PREFACE THE object of this book is to bring together in a con- venient form, for easy reference, some of the best practical hints and schemes of various practical men. Not a mere one-man or one-idea book,- but a book really made by various practical men and one that will be very useful to the old experienced carpenter, as well as to the young beginner. All of the matter in this book was published in The Practical Carpenter, and it was at the suggestion of the editor, Mr. Charles G. Peker, that the task of selecting, arranging and editing the suitable matter was undertaken by me. The task, however, was a very pleasant one, with the knowledge that the information here given will make the work of the carpenter easier and better. Albert Fair. New York, January 6, 1909. HINTS FOR CARPENTERS LVERY carpenter worthy of the name takes pride in his work and has good tools to work with. Not tools that were good, but that are good by being well cared for. The metal parts are not rusty, the cutting edges are keen and not broken here and there. The handles are tight — everything is in working order. In the following pages a number of practical hints and recipes are given for the care, repair, sharpening, re- moving rust, and the selection of tools. A safe rule to follow in making purchases is to buy tools made by a well-known firm, but there are constantly new tools being put on the market by new firms that are of some special value, and therefore all carpenters should know how to select a serviceable tool. Remember that a good, honestly made tool has got to be sold at a good price — the most expensive tools are the "cheap" ones. Carpenters pay particular attention when they buy saws, squares and planes, but outside of these they do not seem to be as particular. 6 HINTS FOR CARPENTERS It is not generally known that the light of the sun and the moon exercise a destructive effect on edge tools. Knives, drills, scythes and sickles assume a blue color if they are exposed for some length of time to the light and heat of the sun ; the sharp edge disappears, and the tool is rendered absolutely useless until it is retempered. Pur- chasers should therefore be on their guard against buying tools from retail dealers and peddlers, which for show pur- poses have probably been exposed for days together to the glare of the sun. The unserviceableness of tools acquired under these conditions is generally wrongly attributed to bad material or to inferior workmanship. A similar preju- dicial effect has been exercised by moonlight. An ordinary crosscut saw is asserted to have been put out of shape in a single night by exposure to the moon. No man should use a dull tool. If there is time to use it, there ought to be time to keep it in good order. There is nothing like having an exact place for every tool and keeping it there when not in use. Keeping tools in good order is as necessary as keeping them in proper place. THE CARE OF TOOLS The wooden parts of tools, such as the stocks of planes and handles of chisels, are often made to have a nice ap- pearance by French polishing, but this adds nothing to their durability. A much better plan is to let them soak HINTS FOR CARPENTERS 7 in linseed oil for a week, and rub them with a cloth for a few minutes every day for a week or two. This produces a beautiful surface and at the same time exerts a solidify- ing and preserving action on the wood. The following recipes are recommended for preventing rust on iron and steel surfaces : 1. Caoutchouc oil is said to have proved efficient in preventing rust and to have been adopted by the German army. It only requires to be spread with a piece of flannel in a very thin layer over the metallic surface, and allowed to dry up. Such a coating will afford security against all atmospheric influences and will not show any cracks under the microscope after a year's standing. To remove it the article has simply to be treated with caoutchouc oil again and washed again after twelve to twenty-four hours. 2. A solution of india-rubber in benzine has been used for years as a coating for steel, iron and lead, and has been found a simple means of keeping them from oxidizing. It can be easily applied with a brush, and is easily rubbed off. It should be made about the consistency of cream. 3. All steel articles can be perfectly preserved from rust by putting a lump of freshly burnt lime in the drawer or case in which they are kept. If the things are to be moved — as a gun in its case, for instance — put the lime in a muslin bag. This is especially valuable for specimens of iron when fractured, for in a moderately dry place the 8 HINTS FOR CARPENTERS lime will not want renewing for many years, as it is capable of absorbing a large amount of moisture. Articles in use should be placed in a box nearly rilled with thoroughly slaked lime. Before using them rub well with a woolen cloth. 4. The following mixture forms an excellent brown coating for preventing iron and steel from rust: Dissolve two parts crystallized iron chloride, two antimony chloride, and one tannin in four of water, and apply with sponge or rag, and let dry. Then another coat of paint is applied, and again another if necessary, until the color becomes dark as desired. When dry it is washed with water, allowed to dry again, and the surface polished with boiled linseed oil. The antimony chloride must be as near neutral as possible. 5. To keep tools from rusting: Take !/2 oz - °f cam- phor, dissolve in 1 lb. melted lard; take off the scum, and mix in as much fine black lead (graphite) as will give it an iron color. Clean the tools and smear with this mix- ture. After twenty-four hours rub clean with a soft linen cloth. The tools will keep clean for months under ordinary circumstances. 6. Put one quart freshly slaked lime, % lb. washing soda, y 2 lb. soft soap in a bucket, and sufficient water to cover the articles ; put in the tools as soon as possible after use, and wipe them up next morning, or let them remain until wanted. HINTS FOR CARPENTERS 9 7. Soft soap, with half its weight in pearl ash, 1 oz. of mixture in about one gallon boiling water, is in every-day use in most engineers' shops in the drip-cans used for turn- ing long articles wrought in wrought iron and steel. The work, though constantly moist, does not rust, and bright nuts are immersed in it for days till wanted, and retain their polish. 8. Mix slowly together 6 oz. or 8 oz. lard to 1 oz. resin, stirring till cool ; when it is semi-fluid, it is ready for use. If too quick, it may be further let down by coal oil oi benzine. Rubbed on bright surfaces ever so thinly, it pre- serves the polish effectually, and may be readily rubbed off. 9. To prevent metal from oxidation : polished iron or steel for instance, the requisite is to exclude air and moisture from the actual metallic surface; therefore, pol- ished tools are usually kept in wrappings of oil-cloth and brown paper, and thus protected they will preserve a spot- less face for an unlimited time. When these metals come to be of necessity exposed in being converted to use, it is necessary to protect them by means of some permanent dressing, and boiled linseed oil, which proves a lasting covering, as it dries on, is one of the best preservatives, if not the best. But in order to give it body it should be thickened by the addition of some pigment, and the very best, because the most congenial of pigments, is the ground oxide of the same metal, or, in plain words, rusted iron, 10 HINTS FOR CARPENTERS reduced to an impalpable powder, for the dressing of iron and steel, which thus forms the pigment or oxide paint. 10. Slake a piece of quicklime with just enough water to cause it to crumble in a covered pot, and while hot add tallow to it and work into paste, and use this to cover over bright work. It can be easily wiped off. 11. Olmsted's varnish is made by melting 2 oz. resin in 1 lb. fresh sweet lard, melting the resin first, and then adding the lard, and mixing thoroughly. This is applied to the metal, which should be warm, if possible, and per- fectly cleaned; it is afterwards rubbed off. This has been well proved and tested for many years, and is particularly well suited for planished and Russian iron surfaces, which a slight rust is apt to injure very seriously. 12. Take 2 oz. of tallow and 1 oz. of resin; melt together and strain, while hot, to remove the specks which are in the resin. Apply a slight coat on the tools with a brush, and it will keep off the rust for any length of time. RUST REMOVERS 1. Cover the metal with sweet oil, well rubbed in, and allow to stand for forty-eight hours; smear with oil applied freely with a feather or piece of cotton-wool after rubbing the steel. Then rub with unslaked lime reduced to as fine a powder as possible. 2. Immerse the article to be cleaned for a few min- utes, until all the dirt and rust is taken off, in a strong solu- HINTS FOR CARPENTERS 11 tion of potassium cyanide, say about ^ oz. in a wineglass- ful of water, take it out and clean it with a toothbrush with some paste composed of potassium cyanide, castile soap, whiting and water mixed into a paste of about a consistency of thick cream. MARKING TOOLS From the wails that most carpenters make about how they lose their tools, it almost seems that the command- ment "Thou shalt not steal" was never given. A good plan is to mark your tools with a distinctive punch mark, so that it will only be seen on close examina- tion. The thief, thinking they are not marked, may after a while be bold enough to use it openly when you are around. And if you should catch him? The common method is to use an etching liquid ; a good mixture is made as follows : Mix 1 oz. sulphate of copper, ^4 oz. of alum, and y 2 a teaspoonful of salt reduced to powder, with 1 gill of vinegar and 20 drops of nitric acid. This liquid may be used either for eating deeply into the metal or for imparting a beautiful frosted appearance to the surface, according to the time it is allowed to act. Cover the parts you wish to protect from its influence with beeswax, tallow, or some similar substance. Some desire something a little more elaborate, so as to give a design or lettering more even than scratching in the wax by hand. 12 HINTS FOR CARPENTERS The method used by wax engravers could be used with success. When any lettering is to appear on a wax cut, they moderately heat ordinary printers' type and press these into the wax, the warm type being easily pressed to the plate or surface of metals to be etched. Designs of which cuts have been made could be used in the same manner. Mr. B. F. Brown describes the method he uses as follows : First, take sandpaper or whetstone and clean off all rust, gum or dirt, from the place where the lettering is to be done; then cover the metal with a thin coating of beeswax or tallow, then take a pencil or any sharp-pointed instrument and do the marking through the wax, being care- ful to have all the letters go through and removing all the wax from the bottom of the letters. Next, take a fluid made from equal parts of common salt and bluestone and water, and by dipping your pencil in the fluid fill all the letters in the wax. If you will do the work nicely you will appreciate it and by the time you have finished your work the acid has finished its work, and you can clean your tool and see what you have done. A HINT ON HOLDING THE RULE The rule, one of the most essential tools of a carpenter, can be used with very little difficulty. Most of the car- penters that I have observed always laid their rules flat on HINTS FOR CARPENTERS 13 the board that they were measuring. It will be readily seen that if some one should come along and push him, as is very frequently the case in a carpenter shop, his rule would slide and he would have to do all his measuring over again. In the illustration of Fig. 1 I try to show how this may be avoided. Instead of putting the rule directly on your board, place the edge of the rule against the side of the board, holding it with four fingers and placing the thumb on the opposite Fig. 1 side. In this way you have full control of your board and rule, and in case you are pushed by one of your fellow workmen, the arm, hand, rule and board all go in the same direction, and will not necessitate doing the work over again. PROTECTING THE STEEL SQUARE The most important thing in regard to a square is to keep the tongue and blade at right angles to each other, and therefore it is a good plan to put a "shoe" on the 14 HINTS FOR CARPENTERS corner or "heel" of the square, as shown in Fig. 2. To make this, take a piece of heavy sole leather, soak it in water until quite soft, and bend it so as to fit the heel. One edge was sewed as shown at A, and through both thicknesses I punched a hole at B through which a piece of strong twine could be passed and tied so as to prevent the shoe from slipping off. The corners above B were cut as shown, so that the twine might not slip. I have found this little contrivance very useful. FILING SAWS The grand secret of putting any saw in the best pos- sible cutting order consists in filing the teeth at a given angle to cut rapidly and of a uniform length, so that the points will all touch a straight-edged rule without show- ing a variation of a hundredth part of an inch. Besides HINTS FOR CARPENTERS 15 this, there should be just enough set in the teeth to cut a kerf as narrow as it can be made, and at the same time allow the blade to work freely without pinching. On the con- trary, the kerf must not be so wide as to permit the blade to rattle when in motion. The very points of the teeth do the cutting. If one tooth is a twentieth of an inch longer than two or three on each side of it, the long tooth will be required to do much more cutting than it should, and the sawing cannot be done well. Hence the saw goes jumping along, working hard and cutting slowly. If one tooth is longer than those on either side of it, the short ones do not cut, although the points may be sharp. When putting a cross-cut saw in order, it will pay well to dress the points with an old file, and afterwards sharpen them with a fine whetstone. Much mechanical skill is requisite to put a saw in prime order. One careless thrust with a file will shorten the point of a tooth so much that it will be utterly useless, so far as cutting is concerned. The teeth should be set with much care, and the filing should be done with great accuracy. If the teeth are uneven at the points, a large flat file should be secured to a block of wood in such a manner that the very points only may be jointed, so that the cut- ting edge of the same may be in a complete line or circle. Every tooth should cut a little as the saw is worked. The teeth of a handsaw for all sorts of work should be filed fleaming, or at an angle on the front edge, while the back edges may be filed fleaming or square across the blade. 16 HINTS FOR CARPENTERS The best way to file a circular saw for cutting wood across the grain is to dress every fifth tooth square across and about one-twentieth of an inch shorter than the others, which should be filed fleaming at an angle of about forty degrees. The following don'ts are by E. C. Atkins & Co. : DON'T bend or twist a hand or rip saw. They are made to saw straight lines with, and not circles. DON'T forget that a handsaw has a spring temper, and, like a spring, if overstretched, will kink or snap. DON'T set your saw below the teeth. The set should be on the tooth and not on the blade. DON'T forget that the less set you give a thin-back saw the easier it will run. SAW HANDLES It is the practice of some carpenters to allow their saw handles to become loose. The other day I picked up a saw the handle of which was so loose it rattled. Now, this is all gross carelessness, for everyone should know better than to abuse his tools in this way. I cannot believe that a man will ever become a finished workman who keeps his tools in such shape, says Fred. Black. STRAIGHT CUTTING SAWS The most exasperating thing in using a saw is to try to cut a rake or a thick piece of wood and have the saw cut HINTS FOR CARPENTERS 17 in a curve, instead of a straight line. A fast or smooth- cutting saw is a pleasure, but a straight-cutting saw is a necessity, says S. M. Lain. I have read several books on saws and their care, but feel that the most important points were gained by ex- perience. The following is part of the experience, and some may profit by it: Fig. 3 Fig. 4 In sharpening a saw which is dull, and not in shape to need new teeth filed in it, set the teeth first (if setting is necessary). Then joint by filing the points of the teeth square with the blade until each tooth is touched with the jointing file. Leave the teeth a little longer in the center, with a very slight gradual curve toward each end. It is sometimes necessary to saw in the center of a plane sur- face, and the ends would scratch if the cutting edge was straight. There are a number of other reasons also. Then file the teeth at an angle to suit the user of the saw. I 18 HINTS FOR CARPENTERS have decided the factory filing — or the angle at which the teeth are filed when new — is the best for general purposes. When filed at too much of an angle, the saw has a greater tendency to saw crooked. File the teeth to an even size and angle till the points are sharp. If this process is done accurately, you have a true-cutting saw — but the perfect filing is the exception or the accident. A very simple and effective way to test a saw after filing is to take a board 12 in. wide and start the saw straight, letting it cut as it will, holding the handle loose in the hand, using the whole length of the blade. Take a steel square and try the cut; if straight, the saw is "good enough. " If it has run either way and the cut is not straight, it is because the teeth are longer on the side it has run (see Fig. 3), or it is set more on that side (see Fig. 4). The teeth should be straightened by refiling or — if not too bad — an oilstone rubbed flat with the blade on the side which is longest will cause it to cut straight. Machine rip and cross-cut saws will run in the same manner from the same causes. It is not as noticeable, but the saw dulls faster, heats, or the boards are drawn from the guide. Try the test, Brother Carpenter, and see how often you have a saw that is "good enough" with the first filing. HINTS FOR CARPENTERS 19 HANDSAW SERVING IN THE PLACE OF SEVERAL OTHER TOOLS Many people have heard about "The Steel Square and Its Uses," etc., but very seldom do you hear about the handsaw and its uses. However, the handsaw is a tool that sometimes comes very handy to use in other ways than to saw in the ordinary fashion, as is explained by Mr. Emery H. Chase as follows : I will mention a few good uses — very good uses ; also a way to shape the point of a saw so a mechanic can keep one in his kit which will come very handy many times. To begin with, the handsaw can be used as a square, and save the use of that tool very often in rough work. When starting to saw a board or scantling you will notice a reflection in or on the side of the saw blade that will indicate or seem to show a continuation of the edge of the board in a straight line — that is, when the saw is cutting squarely across; but let the saw be turned the least bit out of square, and the reflected edge of the board will instantly show a bend or angle. This is a quick and easy way of cutting square — and you can puzzle many a mechanic with it. Now by the same means you can use the saw as a bevel or mitre square. For instance, to cut what is commonly called a "45/" or square mitre : It is quite easy for any one to guess a square ; many people can get it very close. When 20 HINTS FOR CARPENTERS the saw is pointed in the right direction to cut a square mitre, the reflection will show a square. See Fig. 5. While these methods cannot be used much for fine work, they have the merit of quickness that comes in play hundreds of times to every mechanic. The workman who sees a "45" cut in this way will wonder how you get it so close without a line — he cannot see you looking at the reflection, although closely watch- ing you. Fig. 5 One day I saw a fellow try to saw with the point of his saw in the flat side of a board, and I noticed he could saw quite deep, and only one or two teeth were cutting. So I said to myself, if the point of the saw were rounded and teeth were cut in it, it ought to saw deeper; so I tried it, and it worked fairly well, except that it would "catch" or suddenly stop when shoving it ahead. To avoid this HINTS FOR CARPENTERS 21 I filed those teeth on the rounded point so they would cut when the saw is drawn, and this I found to be the best of all. I found I could easily cut through an inch board by having a stroke of only two and one-half inches. And so I keep the saw in my chest, and I find it comes useful very often. Only the other day I had occasion to cut a trap door through a floor, and, having to use the same pieces sawed out for a new door, I did not want to bore through to start the saw, as it would have spoiled the boards on one side of the saw kerf at least, and necessitated the trouble of procuring other lumber. So you see the handsaw in this instance will take the place of brace and bit and compass saw. The point of the saw should be jointed off so the beginning of the curve will be about two inches from the end of the saw, and it should be similar in shape to a sled runner, so that it will look as shown in Fig. 6. A HANDSAW HINT Mr. Emery H. Chase writes that to cut across the nar- rowest amount of wood is the most effective, or at least the most rapid way of cutting with a handsaw. This fact is not generally recognized ; or to be more precise, it is usually ignored. For instance, let a six-inch board be sawed flatwise; that is, so the board will be cut across the broad side; then afterward turn the board up on edge and cut it off 22 HINTS FOR CARPENTERS by sawing the short way through it. It will be found that on an average the board can be cut in two much quicker when the teeth pass the short way through the board. Therefore the lesson to be thus learned is, that when sawing a large piece of wood, to so use the saw as to avoid the teeth all touching across a broad surface at once, and to contrive to make as short a cut as possible. In order to do this in the most practical manner, a piece of timber of very considerable size should be cut by beginning at one corner and sawing to a reasonable depth. As at A, THESE TEETH CU" DURING BACKSTROKE Fig. 6 Fig. 7. Then change the slant of the saw so the timber will be cut to the line B ; then, as the cutting edge of the saw will begin to touch a wide surface, again shift the saw to another position, or slant, and cut inward to C, and so on D, E, F, etc., in their order, as shown. In this way the timber will positively be cut in two one-quarter to one-half quicker than as if it were kept at one angle all the way through. Anyone who doubts this can easily ascertain for himself by the simple method of trying it. HINTS FOR CARPENTERS 23 The same is true in rip sawing. The most rapid and usually the best results are obtained by constantly changing the pitch or slant of the saw from low to high, and vice versa. Fig. 7 This is a method always or nearly always practiced by well-experienced men, but which generally escapes the ob- servation of beginners until they acquire it unconsciously. The point seems to be thus developed that the fewer tooth-points that are cutting, the faster the saw will cut; 24 HINTS FOR CARPENTERS because of the deeper penetration of each tooth under a given amount of pressure. This is also in keeping with the fact that the cutting speed of the different kinds of saws is about in proportion to the spacing of the teeth; from the handsaw to the cross-cut (woodsman's) saw and up to the circular or bandsaw. While in the accompanying diagram a large piece of timber is represented, it should be remembered the same rule prevails if only the cutting of a two-by-four is con- sidered. A HACKSAW HINT Although the hacksaw is principally an ironworker's tool, it is very useful to every carpenter, and in the follow- ing Mr. Emery H. Chase describes a little kink on how to easily make almost twice the usual speed in cutting off shaft- ing and other large irons. Almost everyone knows how brittle the hacksaw blade is — will break almost like an egg shell — and you will notice that the blade is very thin; but the teeth have been given a wide set which makes a saw kerf about as wide as that of an ordinary handsaw. This the manufacturers have to do because of the saws being used by all kinds of people with varying degrees of ability in running the saw in true line. And in a narrow k?rf if the saw be given a short twist it will quickly snap in two. But if the saw were sure to be used only by men who can run it in a straight and HINTS FOR CARPENTERS 25 true manner the set could be much less and the saw would cut correspondingly faster. A wide set means the removal of more metal than otherwise needed, in order to give more play for the saw. It also means the more metal taken out in the saw kerf, the slower the saw will cut. This principle is the same in wood; the more saw dust you make the slower your saw will cut. When you have one or several hours' work in cutting a large piece of iron, just lightly and evenly touch the sides of your hacksaw blade to the side of a revolving emery wheel, removing as near as you can two-thirds of the "set." Your hacksaw blade will then just about make room for itself, but will cut fully as fast again. Of course you must have a good chance to run the saw true and must be careful to do so, for a slight kink will now cause a broken saw blade. It is easier to run a saw true in a large piece of iron than in a small piece, but this also is just where you want the saw to cut fast without extra labor. Save your thin blade for large irons and use an ordinary one for the smaller ones. BANDSAW HINTS Don't forget that small teeth, and lots of them, help to do smooth work just the same on the bandsaw and the circular as they do on the handsaw of the carpenter, says 26 HINTS FOR CARPENTERS a writer in The Woodworker. Another writer in the same excellent paper has the following remarks to make on scroll work with the handsaw: Of all the uses to which the bandsaw can be put, none is more fascinating than scroll work. Whenever it can be employed for that purpose, one should not hesitate a mo- ment in giving it preference over the jig saw, as the work can be done quicker and be of a far superior quality. Our experience with a jig saw has always been, no matter how fine or narrow the blade, that the edges on the under side will be torn and jagged, which, to say the least, detracts materially from the appearance of a job. Nor is it hardly safe to cut close to the line, because, on account of the jerky motion of this saw, it is liable to run away in the wrong direction. In using the bandsaw, however, one has nothing of this kind to fear. The edges are invariably regular and smooth, and one may cut right up to the line without any danger of the saw running off on a tangent. He must be either an unskilled or slovenly mechanic who would allow any such slip to be made ; there is no need of it whatever. A man who understands how to handle a bandsaw knows well enough that the work done by this machine, if care- fully attended to, will need no touching up with either chisel or gouge. In fact, a little sandpapering will make the edges as smooth as the best of trimming can. To secure this result two things need to be kept con- stantly in mind. First, the blade used must be narrow, with HINTS FOR CARPENTERS 27 moderately fine teeth. With such a blade all kinds of curves, even the sharpest, can be followed with ease. The whole responsibility rests upon the man manipulating the piece of wood. If he traces carefully his line, the work will be well-nigh faultless. Second, the saw should by all means be kept sharp. This should be laid down as a fixed rule not to be deviated from, and the observance of which is espe- cially necessary in doing fancy and intricate scroll work. A dull saw never cuts, but scrapes its way through the wood, leaving usually a rough, fuzzy edge. Only from a sharp saw can the best results be obtained; then the cut will be smooth. Now, I imagine some of your readers will say: "I agree with you that so far as sawing along the outside lines of a piece of scroll is concerned, there is noth- ing comparable to the bandsaw. But what about cutting out the inside spaces ?" With rare exceptions, even these can be cut with the bandsaw. Many a fancy piece have I cut out entirely by the use of this machine alone. Take the bracket show r n in Fig. 8 as an illustration. To cut this out get a piece of wood wide and long enough for the scroll part proper, plus the straight piece at the top. Then you can proceed to saw all this out, with the exception of space A. To get at this, make a cut with the saw at a b length- wise of the grain, then follow the inside line, and cut will be accomplished in a "jiffy." After withdrawing the saw, a thin sliver of wood, the same in thickness as the blade. can be firmly glued into the cut, making the piece as solid 28 HINTS FOR CARPENTERS as ever. Last of all, glue on the straight strip c d to form the back of the bracket, and the job will be complete, in appearance quite neat and clean. In our line of work we never use the jig-saw except as a last resort. The work it does never proves satisfac- tory, for reasons we have already stated. In fact, only in cases where we cannot possibly contrive to cut out the inside d Fig. 8 spaces with the bandsaw do we ever think of using it. These instances, however, are very rare, for by means of some device or other we always manage to get along without it. For nice, neat, attractive scroll work our old, reliable friend, the bandsaw, cannot be beaten. One can often bandsaw two or more thicknesses quicker and better than one, and can generally nail the pieces together, outside the pattern, in such manner that the nails HINTS FOR CARPENTERS 29 will hold them till the last cut is made. Nailing inside the pattern is not only open to the objection that it mars the work, but pieces at all slender are liable to be split in taking them apart. SAW FILING VISE Mr. Dan. J. Dodrill gives the following sketch of a saw filing vise that can be very easily made: Tip t £ > mi 2 id' JD ir— B Fig. 9 As will be noted in Fig. 9, the saw is put in between two pieces of board 4 inches wide, 28 inches long and about % inch thick, as shown at D on sketch. B on sketch is a foot-rest, and A is the knee-rest. C C are made of 2 X 4 X 38 inch pieces. £ is a wedge-shaped opening, so that the saw in between D can be pressed in, thus holding it firmly. Pieces A and B should be mortised in end pieces so as to make the thing solid. When in use lean the vise against 30 HINTS FOR CARPENTERS something, put the saw in, place your foot on the rest B and your knee against A, and file away. SHARPENING PLANE IRONS To do good work with a plane the iron must be kept sharp, but frequently the iron is dull and stubbed. When in this condition it is impossible to keep the cutter sharp, for the least wear on the cutting edge would be sufficient to render the tool dull and incapable of doing good work. Fig. 10 Fig. 11 I show in Fig. 10 the shape of a cutting iron as I found it. Now, by examining this figure, it will be seen that the cut- ting edge, A, when pushed forward, will work more like a scraper than a cutter, owing to its stubbedness, and that in fact the back of the basil — i. e., the bevel of the iron at B — pressed against the wood at the back of the cutter, thus preventing it from performing its proper duties. To make this cutter right and capable of doing its duty, I ground the tool until the basil assumed the shape as shown at Fig. 11. HINTS FOR CARPENTERS 31 It will be seen that the cutting edge at A is more acute than at Fig. 10, and that the basil, B, in Fig. 11, is longer than at Fig. 10. It will also be noticed that on Fig. 11 there is a second bevel, c. I explained the use of this second bevel to my friend as being quite necessary to insure good and effective work. I repeat the explanation here : If a cutter is ground down to its cutting edge, so that the line of the basil forms an angle of 25 degrees with the face of the tool, as shown at Fig. 12, then by examining the cut- ting edge, B, it will be seen that it presents a very weak sec- Fig. 12 Fig. 13 tion, much too weak to be lasting or of very much service. Indeed, a plane iron or chisel intended for general use, ground to this form, would be apt to crumble or "nip" out on the cutting edge, or if the temper is so fine that no crumbling takes place, the chances are that, in the case of a plane iron, it will "chatter" or spring and shake during the operation of cutting ; this makes the work wavy and full of transverse ridges, thus rendering the work unsatisfac- tory. Notwithstanding these defects, it has been ascer- tained that an angle of 25 degrees is the proper one to em- ploy when grinding tools for wood-working. To guard 32 Hints for carpenters against the defects mentioned, a second basil is made at the cutting edgt at an angle of 35 degrees, as shown at A, Fig. 13. It will be seen that by this method all the defects of the thin cutting edge are avoided, and all its advantages maintained. In grinding, care should be taken to avoid finishing down to the edge, for if such is the case the edge would be ragged and broken up and would have to be whetted down on the oil stone a full thirty-second of an inch before the cutter would be ready for use. Fig. 14 In grinding tools of this character, the stone should revolve from the operator ; that is, the top of the stone should move away from, not towards, the tool. This gives the operator better control of the work, and gives him an opportunity to see when to cease grinding, which should occur when the basil is brought to within about a thirty- second of an inch of the edge. The process of sharpening should be completed on the oil stone at an angle of 35 de- grees, as shown at Fig. 13. This second basil need be no more than a sixteenth of an inch from the cutting-edge to its termination on the line of basil ; a thirty-second of an inch is quite enough for the HINTS FOR CARPENTERS 55 first few whettings after the tool is ground. Another thing I warned my friend against, and that was making a rocking motion of the hand while whetting the cutter, as this motion has a tendency to give the basil a convex or rounding shape, something like that shown at Fig. 10, which after a while destroys the cutting qualities of the edge. During the sharpening process on the oil stone the tool should be held firmly in the hand, with the thumb on one edge and two forefingers on the upper side of the iron, as shown at Fig. 14, with the end resting against the ball of the hand. The tool should now be placed*on the stone and the left hand brought over and pressed on it, as shown at Fig. 15. Sometimes the operator will find it more convenient to rest the three forefingers of the left hand on the iron while sharpening; on the whole, however, I prefer running the hand over, as shown in the illustration, as it enables one to take a very firm hold of the tool. With chisels, gouges, and 34 HINTS FOR CARPENTERS other handled tools, it is better to lay on the fingers of the left hand than to grip it with the fingers, as it is not ab- solutely necessary that the cutting edges of these tools should be in a right line, or strictly at right angles with the edges of the iron. With plane irons this is different; the cutting edge must be a right or straight line, and at right angles with the edges of the iron on the smoothing-plane, fore-plane, and long- jointer, but it is not necessary to be so particular with the jack-plane; indeed, it is sometimes better to leave the edge of the cutter a little rounding, as it works better than for roughing off stuff and preparing it for the finer-working planes. Another very important matter is the taking off of the corners of the plane irons, so as to prevent the tool from leaving marks on the work, which will be the case if not provided against. It will be seen by examining the iron, 0, Fig. 15, that the corners show clear and acute. Now, if the cutter, O, is tipped up a little on the oil stone, P, and the corners gently whetted off, the iron will cut sweetly and smoothly without having its efficiency reduced in the least. SOME PLANING HINTS I wonder how many of our young carpenters, who have used the old-fashioned wooden planes and have be- come disgusted with them, know that dressing them down with a good steel bottom plane will make them as good as new, says Mr. E. S. Frye. HINTS FOR CARPENTERS 35 To do this remove the bits and handle and lay stock on a level bench, or in a vise, with bottom side up, and plane down smooth and true with a steel bottom plane. Leave it set in linseed oil for ten or twelve hours. The following ideas have been submitted by Mr. C. G. Curry : Fig. 16 shows the face or bottom of a wood-bottom plane, and, as all my brothers know, the throat becomes too large from wear and the plane does not, in consequence, work well and chokes up readily. Fig. 16 I have fixed wood planes in the following way: Take a piece of thin steel, or one-half of a door hinge, and set it in the bottom flush with the face of the plane, as shown in Fig. 16, so as to partly close the throat, and you will be surprised how much better the plane will work. The above has been my own experience. I would like to see some letters from brother carpenters stating their opinion as to which they like the best — wood bottom or iron planes. This is quite an important question in the minds of some mechanics. Also which is the best — the light, 36 HINTS FOR CARPENTERS thin plane iron or the heavy cutters, especially for jack planes or jointers? For my part I prefer the heavy plane iron thickest on the cutting edge, as they do not jump or chatter in the knots or hard places. I also think that most of the plane irons are tempered a wee bit too hard. Mr. L. M. Hodge remarks that every carpenter knows how difficult it is to make a perfectly smooth and even surface on a cross-grained, knurly or birdseye board when there is nothing at hand but a common smoothing plane to do it with, when used in the ordinary way. In smoothing certain kinds of curly redwood and !ike materials it is next to impossible to so sharpen and set a bit in the usual way that a smooth and even surface can be ob- tained, and again it is quite difficult to use a hand scraper on it and keep the surface even and true, as the instrument having no guide will catch on the grain of the wood and gouge out the soft parts to a greater or less degree, be the operator ever so careful. Now these difficulties can be readily overcome by smoothing the wood as well as possible in the ordinary way with a sharp plane set fine, then put a smooth keen edge on the smoothing plane bit and leaving off the cap insert it into the stock bottom side up. Of course the bit must be set very fine for difficult and very smooth surfaces and the corners rounded just enough to keep them from leaving sharp impressions in the wood. It will be seen by reversing the bit as above describe:! HINTS FOR CARPENTERS 37 that the upper or front surface is caused to stand at an angle of about 80 degrees instead of 45 degrees, as when inserted in the usual manner, thus converting it into one of the finest surface scrapers that could well be imagined. While the above may seem very simple, still it may be a pointer that will assist some of the younger "chips" over a rough spot. OIL STONES The oil stone plays such an important part in keeping edge tools sharp that it will be best to say something on this subject here. The reader has no doubt noticed that the oil stone P, in Fig. 15, is surrounded with a wooden case, N. This case serves a twofold purpose: it protects the stone from breakage, and tends to give it weight and solidity while being worked upon. To make this case, a piece of dry pine should be obtained, about 1% inch thick and about 1 inch wider than the stone, and from iy 2 to 1% inch longer than the stone. A recess is then made from a half to three-quarters of an inch deep, according to the thick- ness of the stone. A cover should also be made of wood, to fit loosely over the stone, and which might have its corners bevelled ofif to give it an appearance of lightness. The best Washita oil stones are white, although all of the white stones are not good whetstones. The value of a stone depends upon the hardness, weight and the sharpness 38 HINTS FOR CARPENTERS of the grit, which are the result of the character of its crys- tallization. Every good Washita quarry has its own pecu- liar form or manner of crystallization, and the stones from certain quarries only produce the best sharp cutting and dur- able oil stones. Washita oil stone rock is crystallized silica. The crys- tals are very small, and are formed in clusters with point ends interlaced, leaving numerous cavities. These minute crystals are hexagonal in shape, with sharp points, and can be seen under a microscope when magnified about a hundred times. They are harder than steel, and that is why whet- stones cut from this rock will wear away and sharpen steel tools. Washita whetstones are called oil stones, because oil must be used to fill the cavities and float away the steel particles that are cut off the tools. The peculiar geological formation from which these rocks are taken is not known to exist outside of the state of Arkansas, where it occurs in many of the mountains of Saline, Hot Springs, Garland and Montgomery counties. These strata are in a vertical position, varying from nearly perpendicular to nearly horizontal, and have been consider- ably broken up by upheaval or folding of the earth crust. The best Washita oil stones for carpenters weigh about \y± to 1 5 / 16 ounces per cubic inch, and a stone of standard size, 1% X 2 X 8, should weigh about 1 pound 6% to iy 2 ounces. By continual use the stone will show the wear more HINTS FOR CARPENTERS 39 at the ends than at the middle. This is due to the tool being reversed. When the stone is uneven, a good job of sharpening cannot be done, so the thing to do is to level the stone. There are many ways to do this, and among them all the best and quickest is to take a sheet of No. 1 or l 1 /^ sand paper and place it on a board, fair and straight. Then rub the stone back and forth until level. Two or three sheets of sand paper are sufficient. A writer in The Pattern Maker says that a handy method of quickly reducing parts of a stone which stand too high, or improving the form of a worn slip, is to scrape it with the edge of a piece of glass, used in the same way as a steel scraper is used on wood. A piece of glass can always be obtained when perhaps the ordinary methods of rubbing down are not available or would take too much time. The stone can be scraped in this way either with or without water. Without water is perhaps the best, as it is then easier to see how much is being removed. If one end or one corner of the stone stands higher than the rest, it is easier to reduce to a general level in this way than by the ordinary methods which make the surface flat, but can- not easily remove a slope to one end or one side. A slight inclination in any direction causes the oil to run off the stone, and if is advisable, therefore, always to leave the stone slightly hollow so that the oil will tend to run to the middle when it is left standing. 40 HINTS FOR CARPENTERS HOW TO USE A GRINDSTONE Common grindstone spindles, with a crank at one end, are open to the great objection that the stone will never keep round, because every person is inclined, more or less, to follow the motion of his foot with his hand, which causes the pressure on the same to be unequal. The harder pressure is always applied to the very same part of the stone and will very soon make it uneven, so that it is impos- sible to grind a tool true. To avoid this, put in place of the crank a small cog-wheel of thirteen cogs, to work into the former. The stone will make about 0.7 of a revolution more than the crank, and the harder pressure of the tool on the stone will change to another place at every turn, and the stone will keep perfectly round if it is a good one. This is a very simple contrivance, but it will be new to many of our readers. Another point is mentioned by Mr. Fred Black, and that is when you grind edge tools, be very careful to use plenty of water on the stone, for it does not take very long to draw the temper in the tools. If they become heated, they will be brittle, and the edge is liable to break off. SHARPENING SCRAPERS How should a scraper be sharpened is a question asked even by some old and experienced carpenters. The follow- ing directions by Mr. S. M. Lain answer this question: Most all cabinetmakers understand the process of HINTS FOR CARPENTERS 41 It sharpening scrapers and find it an indispensible tool is just as useful to carpenters in a great many places. A cabinet scraper is a standard tool and can be pur- chased at most every hardware store. They are not sharp when sold, but need to be sharpened then and quite often afterward. Now for the process : Fig. 17 Fasten a file flat on the bench by means of a few screws and file the scraper until the flat sides are straight and free from rust or uneven bumps, Fig. 17. In this pro- cess file both sides of the four edges. Then file the sides and ends square across, Fig. 18, until the edges are straight and have a slight wire edge. Jointing edges may be done a Fig. 18 with a handsaw jointer. Round the corners slightly, as shown at a, to keep the scraper from digging into the wood. The burnisher can be purchased at some hardware dealers or may be made out of a round file. Grind the file smooth and polish it on an oil stone. Sometimes gouges are hard enough to be used for burnishing. 42 HINTS FOR CARPENTERS After filing lay the scraper flat on the bench and rub the burnisher on the sides parallel to the scraper, Fig. 19, and press down hard. Take the scraper in one hand and hold on one edge on the bench ; press burnisher square across the vertical edge and rub upward hard, Fig. 20. Fig. 19 Rub square across twice, then turn the burnisher slightly toward each side and rub upward hard twice, Fig. 21. Repeat the foregoing process on all four edges. The scraper may be fastened in a wood vise and both hands used to burnish edgeways. r Fig. 20 Fig. 21 If a very smooth edge is required rub the corners of each edge smooth on an oil stone before turning. An experienced person seldom gets eight good cutting edges, so a beginner should not be disappointed if all eight do not cut. Enlarged illustrations will make it clearer. All know the reason for sharp square corners. Rubbing the burnisher HINTS FOR CARPENTERS 43 on the sides gives a larger edge to turn back, as shown in Fig. 22. If the burnisher is held at too much of an angle the edge cannot catch when the scraper is held at an angle to suit the hand, see Fig. 23. Too much rubbing with the burnisher will cause the edge to turn too far also. Fig. 22 A heavy cutting edge may be obtained by grinding the scraper to a bevel and sharpening on an oil stone. Just turning one way is all that is needed. Fig. 24. . A Very good scraper for taking off glue, varnish and paint; also for scraping the rough off of floors, etc., is a right wrong Fig. 23 Fig. 24 flat piece of steel (a buggy. spring or file will do) drawn thin and bent at an angle of about 45 degrees. Fig. 25. File smooth on the inside and then bevel to an edge on the outside. They will do very well at first without turning the edge. When dull from filing, only sharpen by first turning edge out, then turn it in to a cutting angle. Fig. 25. A scraper when dull may be sharpened by the process shown in Figs. 19 and 20. In Fig. 19 hold the burnisher 44 HINTS FOR CARPENTERS at an angle to the edge and rub outward as shown by the arrow in Fig. 26. / Fig. 25 Fig. 26 The second and third turnings are sometimes better than the first after filing. One filing will last for about four turnings. USE OF DRAW-KNIFE Mr. R. D. Osterhout says that he finds in using a draw-knife that by working it with the beveled side next to the work it makes a smooth job. If the material is good the piece may be made almost as smooth as if a plane had been used to finish it. This may not be new, but all the carpenters I have talked to about have never tried it. DRILLING OVERHEAD HOLES Anyone who has ever had occasion to drill holes in a ceiling, or any other place where the job has to be done overhead, knows what tiresome work it is, says A. J. Saxe, in Popular Mechanics. A strong man will feel exhausted after holding his arms overhead for five minutes without doing any work, and when the work of feeding and turn- ing the drill is added, it is almost impossible to continue working for more than three or four minutes at a time. HINTS FOR CARPENTERS 45 1 n \°\ stiw ^ — , cfr Z^ \ \ A vJy \\ ^^ Having had occasion to do some overhead drilling, I found that the men's labor could be greatly reduced by means of the device shown in Fig. 27, which consists of simply a board, which acts as a lever, with the fulcrum at the round of the ladder. The board to work well, should be in a horizontal position, and if the round is not in the right place, it may be changed by moving the lower end of the ladder, or if this will not pro- duce the desired effect, a few blocks of wood placed between Fig. 27 the brace and the board will bring the board to a horizontal position. The pressure should be applied to the board as far from the round as possible, thus increasing the leverage. When the ladder is inclined too much it is hard to reach the handle of the brace. In that case the brace can be placed on the other side of the ladder and the board can be raised by placing your shoulder below it. HINTS ABOUT PLUMB-RULES Beginners who have had but little experience in the practical use of spirit levels and spirit plumb-rules are apt to suppose that they can work more accurately with a spirit level or plumb than with a plumb-bob and line. A spirit rule is a little more convenient in most instances, 46 HINTS FOR CARPENTERS and when used by a mechanic of extensive experience and quick discernment one is to be preferred to a plumb-bob and line. But a good bob and line rule will enable a work- man to plumb his work with more accuracy than he can do it with most spirit plumb-rules. A bob and line rule will indicate a deviation equal to one-sixteenth of an inch from a perpendicular line in the height of a door frame, while such a slight inclination would not be shown by the best spirit rule we have ever seen. Besides this, the glasses or vials of spirit levels are not always of the correct form to be affected by a trifling variation from a level or a perpen- dicular line. We have frequently met with spirit rules which would not indicate the inclination of a door frame when it leaned more than one-fourth of an inch from a perpendicular line. Yet beginners, who have not the money to spare for a spirit rule, fancy that they can work with far greater accuracy with such a rule than with a plumb and line rule. After long experience in using both kinds of rules and levels, our preference for ordinary use is decidedly in favor of a bob and line rule made as follows : Procure a piece of clear-stuff pine four feet long, four inches wide, and an inch thick, joint the edges parallel, and strike a gauge mark along the middle ; then cut a hole near the lower end for the plumb-bob to play in. This opening should be at least three inches wide, and of an oval form. Instead of paying fifty or seventy cents for a brass HINTS FOR CARPENTERS 47 bob, make a neat one of lead in the following manner: Break a hole in the small end of a hen's egg-shell and make a pin-hole in the other. Then blow out the contents, wash the inside of the shell, dry it, bury the shell in sand or loam, pack the sand firmly around it, then pour in melted lead until the shell is full. Before the lead becomes solid, hold the ends of a small wire staple in the upper end of the plumb-bob. This will make a neat, true and cheap bob. Procure for a line a strong piece of clock-cord, oil it with linseed oil a few weeks prior to the time of using it, so that the strands will not unwind, and you will have a plumb-rule that will be as accurate as "the left-handed Benjamite who could sling stones to an hairsbreadth and not miss." For setting door frames and plumbing studs, a rule not less than six feet in length should be employed. Then the work will be plumb. SPIRIT LEVELS No doubt many readers will be interested to know the method of making the spirit level glasses. There are two qualities of spirit levels in market : The best kind has the tube carefully ground out on the inside, so as to make it true; the common kind is made from care- fully selected glass tubing, just as it comes from the glass works. 48 HINTS FOR CARPENTERS The tube is sealed at one end by the ordinary method well known to glass blowers, and the other end, after be- ing softened in a flame, is drawn out to a fine tube, which is then broken off and left open. The air in the tube is then expanded by heat and the point of the fine tube plunged beneath the surface of some alcohol. When the tube cools, the air contracts and the alcohol is forced in by atmospheric pressure. By repeating this process the tube can be filled as full as is desirable. It is then held upright and the fine tube is closed by the flame of a blowpipe, and all that is not wanted is broken off. HINTS ON HOME-MADE TOOLS Mr. Emery H. Chase contributes the following useful hints abor.t home-made tools : There are quite a few of the most useful tools the carpenter uses that are home-made, for the reason that manufacturers are slow in producing everything the car- penter wants. And so you can't find them listed in cata- logues, but must proceed to the blacksmith or make them if you wish to have them. Still another useful thing in my chest is the very fine and thin saw. I, of course, could not buy one, so I took a corset steel % of an inch wide and about ten inches long and filed 14 teeth to the inch and did not set it. It works finely. I use it in pattern making; the main object of its use is to avoid much width in the saw kerf. It HINTS FOR CARPENTERS 49 leaves a kerf only wide enough to admit thick writing paper, and cuts smoothly and rapidly, and two pieces sawn in two with this saw and then put together again do not lose much of their original dimensions from the thickness of the saw kerf. It has to be used in a hack-saw frame, how- ever. Just try it though ! Another useful saw, which fitted in proper shape for use, is not for sale so far as I can learn. That is a square- hole saw. Disston sells one, but the angle blade or portion that "turns the corner" is so blunt and increases in width so fast that it is almost impossible to use it in an inch board. After cutting away one-half of this blade and filing new teeth in it and causing the edge to leave the main blade very gradually, it will work all right. To use a saw set on it is quite a difficult matter, however. Another useful thing I tried and that is ridges or cor- rugations running around the hammer handle to keep the hand from slipping, especially when striking hard blows and nailing at a distance. The ridges are like those on the handle of a policeman's club. They should be turned right on the wood when the handle is made. Just carve one out, and you will see how nice it works. Fishermen have good fishline reels; but a good and rapid-winding carpenter's chalkline reel is something not yet dreamed of by the manufacturers. One kind in which the awl can be placed and the line unwound rapidly is on the market, but when the line is rewound it must be twisted 50 HINTS FOR CARPENTERS and twisted while winding it by hand. I made one that works with a small crank, and consequently the line no longer twists and snarls. PINCH BARS Another useful tool is the little claw or nail-pulling pinch bar. In different localities different forms are used ; but after having tried several and having overcome preju- dice against the appearance of some of them, I have finally e jjjj»i>ij»jjj,ijj >»>; t [ |j, 1 1 in n Fig. 28 decided in favor of the 24 or 26-inch square or octagon tool steel bar shown in Fig. 28. It is exceedingly useful in repair work and as a spike puller will save hammer handles. */8- FiG. 29 Mr. Elmer E. List also contributes a sketch of his favorite pinch bar, which is a little different from the one described by Mr. Chase. It is shown in Fig. 29 and is made of %-inch octagon tool steel, with a chisel on one end HINTS FOR CARPENTERS 51 and claws on the other. It cost me 90 cents, and I would not do without it. The round claw end enables one to pull a heavy nail with ease and without the use of a block, while using the chisel end it makes a comfortable and power- ful hand hold. SCREWDRIVERS A screwdriver should be neither too hard nor too soft. A good test is to file the steel ; if it does not take hold it is too hard; if too soft, it can be filed easily. A long screwdriver is easier to work with than a short one. . A writer in The Blacksmith and Wheelwright says that the young mechanic is very apt to ruin one or two good screwdrivers in trying to start set screws or screws that have rusted in. For this and similar work a specially heavy screwdriver is made, the shank being square and strong. The operator can then put all the power he wishes on the wrench, without fear of twisting it or bending the blade. RENEWING SCREWDRIVER EDGE When the point of a screwdriver is worn away, so that it jumps the nick in the screw, it is time that is was sharp- ened as evidently a section of your screwdriver is like Fig. 30, in which the sides of the wedge, in which all screw- drivers terminate, are curves with the convex sides out- 52 HINTS FOR CARPENTERS wards. When the screwdriver is in this condition, it will be apt to slip out of the nick of the screw. The best form is that shown in Fig. 31, where the sides of the wedge are curves with the concave side outwards. With this sort of a point the screwdriver may be easily kept in the nick with- out slipping. To grind a screwdriver into this form it is necessary to use a very small grindstone. Another way to sharpen a screwdriver is by filing, holding it in a vise with the bevel of the point lying hori- zontal and projecting above the surface of the vise jaws; then use a medium flat file on it, giving a forward thrust only, and keeping a horizontal position throughout, directs £ Fig. 30 Fig. 31 the British Optical Journal. Turn the driver over and repeat the operation until the edge becomes very thin. Then file it down to a perfectly straight margin and regulate its width for the size required. This method is more satisfactory than truing up the point on a grindstone. A SCREWDRIVER IMPROVEMENT A writer in The English Mechanic remarking about screwdrivers slipping out of the nick describes a method to overcome this difficulty. All that is wanted is a short tube, big enough to enclose the screw-head somewhat tightly, but only spring-tight, so that it may rise as the screw-head HINTS FOR CARPENTERS 53 comes near the wood. Also, to provide for heads of dif- ferent sizes with the same driver. All this can be done by just turning up a strongish tin tube, three or four inches long, like a slate-pencil case, big enough to slide over the widened point of a round screwdriver, and then fitting spring-tight on the shank by means of a piece of leather wrapped round it; and for larger screws than usual, you might pull the socket off and put a larger one on, with a thicker piece of leather. I find it answers perfectly. You need not even look at your screw, but just put the tubed screw- driver on and turn. It will drop into the nick at the first half-turn, and stay there till the screw is screwed home. HORIZONTAL SCREWDRIVER A writer in Popular Mechanics send a sketch, Fig. 32, of a horizontal screwdriver for use in a corner or other Fig. 32 awkward place. The one shown was made of sheet steel Vg inch thick, % inch wide, and length 4 inches, the width of screw-blade being % inch. SELECTING A LIGNUM-VITAE MALLET In selecting a lignum-vitse mallet choose only the light- colored ones, recommends Mr. Emery H. Chase. Those of light color are taken from the sapwood or 54 HINTS FOR CARPENTERS vital portion of the tree and have greater strength and elasticity than have those taken from the heartwood which is dark. This is parallel to the fact that for the best wagons and buggies and hammer handles, etc., only young or sec- ond-growth hickory is used, thus giving greater toughness and durability. The government tests prove the toughest part of a tree to be the sapwood portion just above the ground. CHISELS When buying chisels see that the handles are good and that the blades are set true in the handle, for if they are not, they will be likely to break under a sharp blow. TO KEEP STEEL TOOLS IN THEIR HANDLES A writer in Machinery says that to keep steel tools in their handles, fill the handle with powdered rosin and a little rotten stone. Heat the tang of the tool hot, and then push it down hard into the handle; when it is cold it will be firmly set. TO MAKE A GLASS CUTTER An old saw-file, with the end freshly broken, makes a very good glass cutter. HINTS FOR CARPENTERS 55 TO MAKE MARKS ON RULES SHOW PLAINLY If you cannot plainly see the markings on the brass side of a caliper rule or slide rule, just rub a blue pencil over the whole slide and clean off, when it will be found that all the graduations are filled in with the blue pencil, and thjese dark markings can easily be seen COUNTERBORING Some time ago there was a kink published in Popular Mechanics, regarding counterboring, which I think worthy of being passed on to my fellow "Chips," who may not have had access to the paper above mentioned. Fig. 33 Every carpenter has had occasion to counterbore holes, and in order to accomplish the job has, no doubt, found it necessary to first plug the hole in order to start the bit screw, which being deflected to a greater or less extent while boring, by the end grain of the plug, gave inaccurate and unsatisfactory results. A much quicker and more accurate method is to use, instead of the plug, a lead disk 50 HINTS FOR CARPENTERS C, which fits the hole B, to be counterbored and is screwed onto the bit point, revolving with it and holding it concen- tric with hole B. All of this is illustrated in Fig. 33. These disks, being soft, are easily made, and a number of different sizes may be kept in the tool chest, and if the exact size needed is not on hand, a larger one may be quickly shaved down to suit. A HANDY VISE Mr. L. M. Hodge says that the vise illustrated in Figs. 34 and 35 is one of the handiest contrivances in its sphere that could well be imagined. ^^vF^^V^ ^r -aw- Fig. 34 Fig. 35 As will be noticed, this device consists of a small vise or clamp mounted on a % X 3%-inch stud, which is pro- vided with a thumb-nut that enables one to readily fasten it to a saw bench or other object in almost any position, and to swing it about to suit the work that he wishes to hold. This little tool is especially handy in finishing work, to HINTS FOR CARPENTERS 57 hold short pieces of base while being mitred, moldings while being coped, and various other work, such as holding a board while straightening the edge with a plane when a work bench is not at hand, etc., and when used in con- nection with the cross timbers shown at 5, makes the most convenient and satisfactory device for holding doors while being fitted and hinged that I have ever seen employed for the purpose. One cannot appreciate the convenience of this little tool or the great variety of work that it can be used for until he has owned one. Fig. 36 If you cannot buy one already made, it is only a few minutes' work to make a pattern and have your foundry man to make one, which should not cost more than 75 cents complete. A SIMPLE BENCH STOP Mr. E. E. Bragg submits a description of a simple bench stop, which, he says, may be old to some carpenters ; it is new to me, as I never saw or heard of anything 58 HINTS FOR CARPENTERS like it until I made one the other day and found it to be a success. At the edge of the bench fasten a piece of wood 1 inch square, 6 inches long, by means of two screws. Take a piece of 1 by 2, 12 inches long, and cut it like the form shown at B; fasten this down by means of one screw at A, but not down tight, so that it can slip backwards and forwards so as to clamp your boards, as shown in Fig. 36; C is a guide piece. BENCH HOOK As my contribution, says Mr. Jacob C. Miller, I sub- mit to your readers a sketch in Figs. 37 and 38 of a very convenient tool for the top of a work bench. It is a bench hook or a tail stop for a bench. Fig. 37 The diagram No. 3 shows the bench hook ; it is made of 3 /i6 incn stee l and about % inch wide - From A to C it is 6 inches long, and from A to B it is 4 inches from centre to centre, with the points A and B at right angles to the upper face ; the points are about % inch in length. Sketch No. 1 shows the hook holding the board flatwise HINTS FOR CARpENTERS 59 cn the bench with the point C in the end of the board and the two points A and B slightly driven in the bench, thus holding the board in such a manner that a man may plane the board lengthwise or crosswise. It is also very conve- nient for holding a board on the bench while sawing for gains to be routed out. Fig. 38 Diagram No. 2 shows the hook holding a board on edge on the bench while planing the edge or while nailing a strip on the edge of the board. The two points A and B are driven in the end of the board, while the point C is driven in the bench, therefore securing the board from falling over. Anyone wishing a handy tool of this sort can have a blacksmith make one; its cost will be a very small item. A SIMPLE BUFFER I have recently been interested in buffing shellac from hardwood floors and have tried nearly every kind of buffer available, but have found none with which I could do the work so easily and effectually as the one described below, says Mr. George W. Webster. It is one of my own im- 60 HINTS FOR CARPENTERS provements, and I describe it for the benefit of any fellow carpenter who may appreciate the same. It is cut from a 2 X 6-in. piece of plank and shaped like Fig. 39. To hold buffer in place a pin is inserted in the hole a. I use a buffer about 2y 2 inches square and cut a saw kerf into the heel of the block, so the buffer will extend below the block about % inch, so it will have plenty of room to clear off shellac and shavings. I sharpen buffer with a file and give a short bevel; then sharpen on oil stone, taking a small gouge to turn the edge of buffer up, so it will cut readily. )« 14' - Fig. 39 Inserted as shown on diagram, I find an angle of ninety degrees about right to turn up edge of buffer. With this instrument I can remove three coats of shellac from 300 square feet of floor in ten hours, down to the natural wood, which includes a thin shaving of the wood. HOW TO MAKE A GLUE SCRAPER Nearly every woodworker has a glue scraper, which is generally made from a strip of iron or a flat file, but HINTS FOR CARPENTERS 61 a better one can be made as shown in Fig. 40. The handle is made from a piece of hard wood 1% X 1% X 12 inches. The blade is made of an old plane bit and is fastened to Fig. 40 the handle by means of a screw and washer, says R. B. Gregg, in Popular Mechanics. USE FOR OLD HACK-SAW BLADES A writer in Machinery says a useful scraper for wood is made as shown in Fig. 41. The handle is shaped, as shown, from steel or brass. The dowels hold the parts Jdacitntri M.T. Fig. 41 of the handle in line and prevent the blades from slipping; they also locate the blades. The blade, being very thin, can be easily sharpened and kept sharp. It makes a most useful patternmakers' or joiners' scraper, and the blades cost 6% HINTS FOR CARPENTERS nothing to replace, broken or worn-out hack-saw blades being used for the purpose. A rough and ready handle can be made by sawing a narrow slit in the end of a piece of hard wood and driving in the blade tightly. A SIMPLE SANDPAPER HOLDER Mr. J. F. Spellman offers a very good suggestion for making a convenient sandpaper holder — an article which every woodworker has occasion to use practically every day in the year. \^nr>' J JS^^m^^^^£i^im^mi^^m^\J.&^^:: rELTjar SAND PAPERS* Fig. 42 I take a piece of %-inch pine about 4% X 6 inches, and on each end of this I glue a %-inch strip, then cut a piece 4y 2 inches wide and long enough, so that it will fit snugly between the two i/^-inch strips. On the large piece of wood glue a piece of thick felt on the side opposite that to which the end strips are glued. Place a piece of sandpaper around the part with the felt and fasten it in place by pressing the 4y 2 X 5-inch piece between the strips, and it is ready for use, as shown in Fig. 42. To make it easy to hold, round the edges of the top piece. HINTS FOR CARPENTERS 63 FOLDING SANDPAPER The following method of folding a sheet of sand- paper, so that no two sanded surfaces will come together, will often prove a great convenience, and a whole sheet folded in this manner forms a pad for the sandpaper block. It is submitted by Mr. W. B. May. Fig. 43 The sheet is first cut half-way through in the middle, as at A in Fig. 43. The quarter-marked 2 is folded on 1 (the illustration showing the plain side of the sandpaper) ; then this is turned on 3 and finally on 4, forming a pad of four thicknesses, no two sanded surfaces coming in contact. EASILY MADE TRAMMEL POINTS A trammel point in which no fine adjustment is re- quired, can be made from pipe fittings and a steel rod, 64 HINTS FOR CARPENTERS as shown in Fig. 44. The device can be made with either one traveling point, A, and one stationary point B, or with two traveling points, as may be desired. It was de- scribed by Mr. George A. Madison in Popular Mechanics, In making the traveling point a two-light gas fixture body is drilled to receive the %-inch rod, and tapped for ^ ' Ma//eab/e ree Two-fight g&5 fixture body 21 J-" J fee/ Rod " 5 fee/ Rod Trammel Points Fig. 44 the steel point, as shown. The 14-inch nipple acts like a set- screw, and the ^-inch malleable tee serves as a handle. The %-inch steel rod can be made any length desired and can be bent either hot or cold. TOOL BOXES One of the interesting features of the Practical Car- penter was the variety of tool boxes described by various readers. In the following pages a few of these are given, lack of space prevents all of them being republished here, although all were interesting.

Bogert, who says that it is made of %-inch material, except the drawers, which are made of %-inch stuff. Cy- press is used throughout, as this lumber can be bought in any width up to three feet, is clear and easily worked, and will stand the weather. The box is divided as follows: Three drawers to be used for small tools ; a large space for large tools ; and a small space for saws in the lower left- hand corner. The drawers, unless made right, will "stick" when drawing them backward or forward. In order to overcome this difficulty they should be made about 1 / 1Q of an inch smaller than the space they occupy. All drawers should have covers hinged at the back to keep out dirt. I would like to call attention to the divisions in the third drawer. The space A is used for the level, the space B is used for miscellaneous articles, and the smaller divisions are used for screws, small nails and a great many other small things. All cross partitions should be mortised into the sides, and they should be screwed together, as nails will work loose. All other joints should be miter joints and well nailed. After all this has been completed, the top should be covered with either zinc or galvanized iron, which makes the box waterproof. The handles should be placed about one-third of the distance down from the top. 68 HINTS FOR CARPENTERS Fig. 47 shows the design of Mr. George W. Webster, and he has the following to say about it: I find it very much handier than any I ever used. It is on the plan of a bureau ; there is no cover to lift, but drawers to pull out. I keep saws and planes in the bottom drawer ; hammers, bits and brace, shop axe, files, floor-set, etc., in the 7-inch drawer; boxes containing brads, screws and special kinds of nails in the 5-inch drawer ; chisels and small tools in the 3-inch drawers. % ^ to* £& 3-3B- ^3v an £2> £^ T — ®-3ftr— Fig. 47 The chest weighs 300 pounds when the tools are all in it; but the way the castors are put on, one man can easily move it anywhere the castors will roll. The two castors in the middle being % inch lower than the two end ones, make it easy to guide the chest anywhere, and also to swivel or turn it around. The convenience over any other chest is a place for everything, and everything in its place. When transported HINTS FOR CARPENTERS 09 on cars, they never stand it on end or tumble it about. My experience with the kind you have published is that at the end of a journey the tools are found all mixed up and the chest more or less damaged. The strap of iron shown in the middle of the front is to keep the drawers in place when chest is being moved. It is 1% inches wide and drops over a staple in which a padlock is placed. It is in two parts, meeting or lapping over each other at the staple ; at top and bottom it is attached to strap hinges. My chest is made of pine, stained cherry. Drawers dove-tailed and work easily on ways. Quite a novel design for a tool chest is submitted by Mr. Lauritz Smith. Fig. 48 is self-explanatory. Plans of shelves, trays, etc., may be changed to suit. He thinks that this is the best plan for a tool chest that he has ever seen. Every tool has a certain place, and one can find any tool de- sired without trouble — in the dark, if necessary. If trays, etc., are proportioned right, there will not be an inch of waste space in the chest. Almost any tool chest may be converted to this plan with little work. Partitions are all made from %-iftch pine. By way of variety we show in Fig. 49 a tool chest made for sale by a dealer in tools. It will no doubt give suggestions on how a box can be conveniently arranged. In connection with the different designs of tool chests, Mr. Emery H. Chase gives the following hint: Let the TO HINTS FOR CARPENTERS HINTS FOR CARPENTERS 71 carpenters try wheels on their chests, like those on safes. I have four 6-inch»iron wheels under my chest, and they are "just the thing" needed. You can wheel your chest over a sidewalk for any short distance quite easily and better than to wait for a drayman. And the wheels are useful every time the chest is moved. Try it! Fig. 49 So much for tool chests ; but the carpenter sometimes wishes a light box that can be easily carried about. Some- thing along the line of a dress-suit case is shown in Fig. 50, which was submitted by Mr. Mansfield Bolls. The tools are held in place by common galvanized iron, cut in strips 1 inch wide, and long enough to screw to inside of box and crook up to form a kind of spring hook. The 72 HINTS FOR CARPENTERS Fig. 50 HINTS FOR CARPENTERS 73 box is, when closed, 6 inches wide, 16 inches deep and 24 inches long (inside measure). The square is the last tool to be put in, so it is always on top and ready for use. The three planes fit in a box made separately for each. The level is held by two strips of iron, one of which is fastened by only one screw, so it can be turned down to let the level go in and out. By being held in these fastenings, which form a spring, the tools are held firmly in place, so they will not "rattle" in carrying. The box is made in two parts of equal size, and hinged together, forming a kind of "grip" or case. At each end, in addition to the handle Fig. 51 which is on top, rings may be attached to fasten a strap to go over the shoulder. Fig. 51 shows the design of Mr. F. C. Zook. The beauty of which is that when open it lies flat down, so there is no need to disturb any of the tools but the one wanted. My chest is made of %-inch cedar ; it is strong enough for all ordinary purposes. The interior can be finished with drawers and partitions to suit the ideas of the user. The ends are 8X13 inches, cut as shown ; the two 74 HINTS FOR CARPENTERS divisions are held together at the bottom by three brass hinges, the top by two clasps and lock. A handle on top makes it convenient to carry. If it is made 32 inches long inside, it will hold any 28-inch rip-saw. If a 28-inch saw is used, it can be placed in the lid or leaf. Three saws can be placed in the lid by having the blade end of one saw placed between the handles of the other two. When finished in cherry stain and varnished, this box looks neat. ' *J t^ ^ ^ a i JJ-ratu-er spo.cg -PoV^-gn Fig. 52 Another shoulder box that folds down is shown in Fig. 52, which is submitted by Mr. Luther Moseley. It is made of i^-inch stuff, except the ends, which are % inch thick. The box is 12 inches high and 8 inches wide. The ends are cut in three pieces each. On the middle of the top is a piece of wood fixed to the ends to which a handle is fastened. The sketch plainly shows how the box is arranged. One side comes down a little lower than the other. The idea is to not expose the teeth of the saws ; hence the side in which the saws are placed is not HINTS FOR CARPENTERS cut as low as the other. This space for the saws is 2 inches wide, so I can place two saws with handles together and one with the handle at the other end and with the blade between the other two handles. In the main part of the box place planes and such tools as are needed. In the drawer or till place chisels, bits, line, chalk, level, etc. The handle bar is 2 inches wide and rabbeted on both sides, so as to receive the sides when closed; this makes the strain on all the top the same. Fig. 53 Fig. 54 A leather handle on the bar costs 25 cents; clasps to fasten the sides, eight brass corner pieces, hinges and screws cost about one dollar. When I stained it with red stain, I had a shoulder box I am not ashamed to take in any crowd of workmen. The till is placed in the box on cleats, fastened at each end with small screws, and when the tools are properly placed in my box I can stand it on end without having the tools fall about. 76 HINTS FOR CARPENTERS A handy little box which can be easily carried is shown in Figs. 53 and 54. It was made by Mr. F. A. Williams and is only 19% inches long. One drawer in each end for two sizes of bits. The lid cheek, with Vs-inch rod connected, locks the two drawers ; then turn the key and the box is all locked. The bottom is *4-inch ash, and the balance is 5 / 16 -inch cypress, glued and well nailed. Stain or finish in natural wood, with five sets of brass hinges. Handle of leather, iy 2 inches wide, bolted to lid. This will hold all of the tools, except the saws and steel square. 7v Fig. 55 Something out of the ordinary is a good, light hand tray for carrying a kit to do odd jobs. Fig. 55 shows a design submitted by Mr. L. Smith. The principal dimen- sions are given on the figure, and a good length is about an inch longer than the longest saw you intend to carry. The height of end pieces may be about 13 inches if made with drawer in bottom, which will be found a great conve- nience to carry small tools. A shoulder strap will be found a great help, if one has to carry the kit any distance. HINTS FOR CARPENTERS 77 Of course the dimensions will be governed by the amount of tools carried, and their size, but Fig. 55 shows the dimensions of a handy size. SOMETHING ABOUT NAILS The following hints are submitted by Prof. John Phin : Every one is familiar with the fact that a piece of rusty iron, wrapped in cotton or linen cloth, soon destroys the texture of the fabric. A rusting nail, for example, if laid upon a few rags, will soon produce large holes in them ; or it will, at least, render every point that it touches so rotten that the cloth will readily fall to pieces at these points, and holes will be produced by the slightest hard usage. From this well-known fact we may draw the con- clusion that iron, during the process of rusting, tends to destroy any vegetable fiber with which it may be in con- tact. This explains, to a certain extent, the rapid destruc- tion of the wood that surrounds the nails used in outdoor work, whereby the nail is soon left in a hole much larger than itself, and all power of adhesion is lost. Part of this effect is, no doubt, due to the action of water and air, which creep along the surface of the nail by capillary attraction, and tend to produce rottenness in the wood, as well as oxidation in the iron. But when we compare an old nail- hole with a similar hole that has been exposed during an equal time, but filled with a wooden pin instead of an iron nail, we find that the wood surrounding the wooden pin 78 HINTS FOR CARPENTERS has suffered least; and we may, therefore, fairly attribute a destructive action to the rusting of the iron. It might, at first sight, be supposed that, as the oxide of iron is more bulky than the pure iron, the hole would be filled more tightly and the nail held more firmly to its place. But, although this effect is produced in the first instance, yet the destruction of the woody fiber and the pulveriza- tion of the oxide soon overbalance it, and the nail becomes loose. Of course, the iron itself being also destroyed, its strength is diminished ; and we have, therefore, a double incentive for preventing or diminishing the action that we have described. The only way to prevent this action is ti cover the nail with some substance that will prevent oxidation. This might be done by tinning, as is common with carpet-tacks, which are now extensively tinned for the purpose of preventing them from rusting, and thus rotting holes in the carpets. Coating them with oil or tal- low would be efficient, if the act of driving did not remove the protecting matter entirely from a large portion of the surface. But, even then, it will be found that the oil or fat is stripped off the point and gathered about the head in such a way as to prevent the entrance of air and moisture into the hole. The most efficient way to coat nails with grease is to heat them to a point sufficient to cause the grease to smoke, and then pour the grease over them, stirring them about in a pot or other vessel. When the nails are hot, the melted HINTS FOR CARPENTERS 7& grease will attach itself to them more firmly than it would have done if they were cold; indeed, so firmly that it will require actual abrasion of the metal to separate it. In erecting fences, laying plank or board sidewalks and the like, it becomes an important matter to secure the nails against the influence that we have mentioned, and yet the work must be done rapidly and cheaply. Nails may be readily prepared as described, or they may simply be dipped in oil or paint at the moment when they are driven in. And we have found, * by experience, that in cases where it is not advisable to paint the whole fence, it is, nevertheless, a good plan to go over the work and touch the head of every nail with a brush dipped in oil or paint prepared so as to be of the same color as old wood. Nails may be more easily driven into hardwood by first touching the small end in grease. To draw a iusty nail that sticks tight, first hit it a blow with a hammer sufficiently hard to start it in a little, which breaks the rusted connection; the nail then can be easily drawn out. SOMETHING ABOUT SCREWS There are poor as well as good screws. A good screw should have sound and well-cut heads, no breaks or flaws in the thread part, and good gimlet points. If they are warmed and dipped in raw linseed oil or tallow, it will prevent their rusting, hence they can be unscrewed easily. 80 HINTS FOR CARPENTERS When the work in which they are used is exposed to much wetting and drying, screws are of little use. They soon rust, rot the wood around them, and draw out, looking like screws without threads. Dipping them in thick paint or tallow before driving them helps to protect them. When used in inside work and in soft wood, they may be dipped in glue. This makes them hold well, and when thus treated they are more easily driven. But the best plan is to heat them with oil or tallow m a pan. The grease then adheres more strongly, and the protection is more complete. It is a common thing, when a screw or staple becomes loose, to draw it out, plug up the hole or holes with wood, and then reinsert it. But screws and staples so secured soon come out again. It has been found that a much better way is to fill up the holes tightly with cork. Screws and iron so secured will remain perfectly tight just as long as when put into new wood. HOW TO LOOSEN SCREWS Few things are more vexatious than obstinate screws, which refuse to move, much less to be drawn out, and in the struggle against the screwdriver power suffer the loss of their heads, like conscientious martyrs, rather than take a single half-turn backwards from the course they have followed, and from the position they have been forced into. Like obstinate children, they must be coaxed or rapped pretty hard on the head, according to circumstances; HINTS FOR CARPENTERS 61 in fact, whoever has a tight, obstinate screw to "draw out" must keep his temper down and his resolution up, quite as much to the sticking point as the screw does. If the screw is turned into iron and not very rusty, it is only necessary to clear the head with the wedge of the driver, and let a few drops of oil penetrate to the threads; but, rinding that excessive heat or rust has almost fixed the screw immutably, then heat, either by placing a piece of hot iron upon it or directing the flame of the blow-pipe upon the head, and, after applying a little oil, turn out gently; but care must be taken not to let the tool slip so as to dam- age the notch. If, however, the screw refuses to come out, try to force it back with a blunt chisel, smartly but care- fully tapped with a light hammer ; but if evidently nothing can dislodge the enemy, it is best to cut the head away and drill out the screw. When an obstinate screw happens to be in wood, merely give it a few taps on the head ; but, fail- ing that, heat it with a piece of hot iron, heat is applied to its head, which may be readily done with a red-hot kitchen poker, when it may be easily turned. A SCREW AND NAIL BOX One of the most inconvenient things for a carpenter is the hunting for the different sizes of screws and nails. In- stead of looking through various bags or other receptacles for the size or sizes required, why not make a box for the screws, also one for the nails, and offset this trouble. 82 HINTS FOR CARPENTERS To make a strong box for screws or nails is a very simple and quick matter once you get at it. A box 15X^X9 (inside measurement) will be found adequate for most wants. The ends can be joined together accord- ing yy ys yA m / ^V— t Fig. 56 ing to taste, but dovetail joints for this purpose will answer to best advantage, because a joint of this class cannot be easily pulled apart. Fig. 56 shows a method of laying out a joint of this kind. Three dovetails are all that are required i_I i i i r Fig. 57 for the height of the box. (A represents the end, B the side.) After the sides of the box are dovetailed together, the bottom is then ready to be put on. This part of the box should be screwed on, as nails become loose too quickly. HINTS FOR CARPENTERS 83 The box is now ready for the divisions to be put in. Thin stuff is all that is required, and this should be notched together as shown in Fig. 57. (A represents the width for the division, B the length.) Fig. 58 The box when completed, if the above instructions are complied with, will contain fifteen divisions, about 3X3 inches, which allows for as many different kinds of nails or screws. Fig. 58 shows the box when completed. REPAIRING A GLUE POT A few winters ago my glue pot was cracked with frost by having water left in it over night. I repaired it by taking some iron filings. By using a horseshoe magnet only the clean filings without dirt were obtained. After scraping the rust off along the crack I spread the filings on, then moistened it with a few spoonfuls of sal ammoniac solution from an electric battery. After drying a few days the filings were rusted together and the pot fit for 84 HINTS FOR CARPENTERS use. It is still in use, but in winter no water is left in it over night. HOW TO MAKE AN ELECTRIC GLUE HEATER In the shop where electricity is used the electric glue heater is the simplest device of its kind. The illustration. Ceiling or wall rosette Water line rncflnftescetu lamp Fig. 59 Fig. 59, shows how it is arranged. An incandescent lamp with a waterproof socket is suspended in the water in the kettle, and the joints between the glue pot and the kettle are made perfectly tight. A 32-candlepower lamp will boil the water in from two to four minutes, says a cor- respondent of Woodcraft, while six or eight candlepower will keep the kettle warm. HTOTS FOR CARPENTERS 85 REPAIRING OLD GLUE-JOINTS Sometimes two pieces of wood which have been joined together by glue separate at the joint. Before gluing them together again, the old glue should be carefully washed off with warm water and the surfaces allowed to dry. Then proceed as if making a new joint. TO PREVENT GLUE CRACKING Glue frequently cracks because the dryness of the air in the rooms warmed bv stoves. The addition of a little chloride of calcium to glue will prevent this disagreeable property of cracking. Chloride of calcium is such an absorbing salt that it attracts enough moisture to prevent the glue from cracking. REPAIRING A BROKEN POLE The following may be of interest to a number of read- ers. I was called upon to repair a broken flag-pole, and it was necessary to repair it as soon as possible, as a flag- raising was to take place. As there was no time to get iron straps, I hit upon the following scheme : Fig. 60 shows the break. Two saw-cuts were then made on each side of the pole, and the strips shown by the dotted lines were removed. One of the saw-cuts was made about a foot from the break, and the other at a dis- tance of two feet. 86 HINTS FOR CARPENTERS These strips were then turned around and nailed on to the middle portion of the pole, as shown in Fig. 61, which explains clearly how the repair was made. The pole was then ready to be used. Very likely this would be strong ._J L_. B >NN ^ yv/> Fig 60 Fig. 61 enough, but in a few days I had iron rings made and placed around the joint as a matter of precaution. SPLICING TIMBERS Somewhat similar to the previous problem is the method of splicing heavy timbers, which is submitted by Mr. D. J. Dodrill. Suppose it is required to have a 24-foot piece of tim- ber and the only available pieces are 12 feet long. The method of doing this is shown in Fig. 62. Let A be 12 feet long and A\ be 12 feet long; thesQ are to be 24 feet long after being spliced. HINTS FOR CARPENTERS 87 Cut a piece out of A as shown in sketch, any length and width desired, and from A\ the same width, only twice as long as a; put a\ twice as long as a on A and the piece a out of A on A\. Get two pieces of strap iron and finish as sketched. B represents bolts, C where the two 12-foot pieces come together. The sketch is plain enough without further explana- tion. It does away with a clumsy splice as is generally in use. n i n p i in i n r r mmmmmm ing for butts. Then apply the rod to the jamb of the frame pushing the steel plate against the head which will indicate the thickness of clearance between the door and frame. Where neat and well fitting work is required, the door jambs should be beveled off slightly with the fore plane to relieve them of uneven places on the surfaces. DOOR HOLDERS In the above article by Mr. Browne, he describes one form of a door holder; there are quite a number of other forms in use by various carpenters, and it will no doubt be of considerable interest to present a few. Fig. 75 One of the simplest is shown in Fig. 75 : it is simply any piece of waste wood, cut so that it will fit tightly between the jambs, with a notch large enough for the door to fit in. This door holder is easily put up in any doorway of the same size, and is simpler than Fig. 76, which can also be made very easily from some waste pieces of studding. Fig. 77 shows another simple design which will hold the door firmly in place while being worked, and has the additional advantage of being very quickly and cheaply 100 HINTS FOR CARPENTERS made, as all the material can usually be obtained from waste pieces on the job. The piece A is % X 10 X 20 or 24 inches. B and C are % i ncn thick, 10 inches long and 8 or 10 inches high. D is a piece 2X2 inches, fastened on the back side of A, to take the end thrust of door while being dressed. Fig. 76 B and C are fastened to A by nailing through A from the under side. The distance between B and C should be same as thickness of door you are working. Drive Fig. 77 nails at E and F, which will secure holder while in use and are easily removed, allowing holder to be removed from room to room. Mr. E. E. Bragg says that the previously described door holders are well enough as he has used them, but HINTS FOR CARPENTERS 101 that the kind shown in Fig. 78 is the best. In his work he is called on to plane quite a number of doors and found that this one holds the door more firmly. To construct this, take, for A, a 1 X 4, 30 inches long; C, a 1X4, Fig. 78 16 inches long; £, a 2 X 6, 7 feet long; and B, just a plastering lath or a 1 X 2 nailed on either side to hold the door; nail them 1% inch apart, or whatever the thick- ness of the door may be. D ^^ B v sss/y.- .V '/ 1 1 *v vN Fig. 79 A very interesting communication was received from Mr. F. C. Bell, in which he says his design, Fig. 79, is superior to other door holders. The one you first described is not a good one to stand the end thrust which the door receives when being dressed. 102 HINTS FOR CARPENTERS The second one, which I used myself until I discovered a better way some years ago, has the great disadvantage that you cannot drive it tight enough between the door jambs without driving them apart, and a door fitted when the holder is in place is apt to bind when it is removed. Fig. 79 is a sketch of one which I have found to be satisfactory in both these respects, and it also has the advantage of preserving the lower edge of the door while the other is being dressed. I Fig. 80 It consists of two pieces of 2 X 6-inch or even 1-inch stuff, nailed together at right angles, the bottom one about 5 feet long, and the other must be cut off so it will not come above the door. A brace is fastened on one side at C. Two cleats are also nailed on at A to suit the thickness of the door, and another one at B will keep the door firm, while a nail driven through at D will keep the holder firm, and is easily removed, allowing it to be taken from room to room. HINTS FOR CARPENTERS 103 Our old friend the trestle can be used as a door holder if the saw horse is made like Fig. 80. This is the sugges- tion of Mr. J. M. Karrash. Use two trestles, place them in position, so that the door will rest as shown; then nail the blocks on the floor to hold the door from slipping. DOOR AND SASH HOLDER For shop use a useful hint is made by Mr. E. S. Frye and shown in Figs. 81, 82 and 83. This little tool can Fig. 81 — Holder Closed be carried in the drawer of your bench, and as it is only 10 inches long it will not take up much room. The handle can be made of hard, tough wood, also the eccentric, which must be as thick as the sash or door to be dressed. Holes can be bored in the side of bench to admit different lengths of sashes and doors, and it takes only a few minutes to adjust it. The illustrations explain the method and man- ner of construction. 104 HINTS FOR CARPENTERS TO MAKE BADLY FITTING BLINDS AND DOORS SHUT TIGHTLY When blinds and doors do not close snugly, but leave cracks through which drafts enter, the simplest remedy, recommended by Mr. Schuetse, building commissioner in Dresden, Germany, is this : Place a strip of putty all along the jambs, cover the edge of the blind or door with chalk, and shut it. The putty will then fill all spaces which would remain open and be pressed out where it is not needed, when the excess is removed with a knife. The chalk rubbed Fig. 82 — The Eccentric Fig. 83 — Holder Open on the edges prevents the adhesion of the putty to the blind or door, which can then be opened without adhesion, and the putty is left in place, where it soon dies and leaves a perfectly fitting jamb. Any smart boy can do this. HINTS ON FITTING SASH Mr. Harry H. Rotherwel sends in a sketch of a "sash holder" that will be found to pay for itself in the saving it will do in preserving the edge of your plane irons and the face of your plane. I myself found it troublesome HINTS FOR CARPENTERS 105 before I used this plan, as whenever a new building is sup- plied with a floor, a troop of spectators will always walk up to the windows and look at the surrounding neighbor- hood. They carry more or less sand or dirt where they walk or step. Often, also, the plastering is done before the sash is fitted because the planing mill man is behind in deliveries. \ i i f! Ox ' ' X.

The holder is shown in the figure and is made of % X 4-inch stuff for floor and upright piece ; for the brace almost anything will do. Nail it together and brace it to the angle of your steel square. Fasten a block % X 2 inches and 4 inches long 106 HINTS FOR CARPENTERS opposite your brace, and it will hold your sash very firmly. In use the sash holder is nailed to the window sill and then you are ready to begin. The upright piece of the holder may be 26, 28 inches, etc., according to the height of the window sill. DOOR CHECK Mr. Francis L. Bain submits a design of a door check, Fig. 85, which has proved to be exceedingly useful when it was desired to hold open any door which was fitted with a spring, or a door which was inclined to "slam to" on a windy day. iwVv^ JD oor F^rfK] ////////'//?////// "/ Fig. 85 The check, A (about 7 X % X % inches), is hinged on a %-inch dowel, which extends about half-way into each of the two supports, B, which are about 3 X % X % inches, with two round-head screws attaching each sup- port to the floor. A small spring, C, of medium tension is let into A near the end as shown, so it just touches the floor. A is depressed by a light pressure of the foot and HINTS FOR CARPENTERS 107 comes back into its original position when pressure is removed. The slot is cut to fit the thickness of the door on which it acts, and if the point of A extends about 1% or 2 inches beyond the surface of the door, and beveled as shown, the door will easily ride into the slot without any difficulty. The check is very useful, as a trial will quickly demon- strate. The height of this check is determined by the thick- ness of the threshold (which is usually about % of an inch). If greater or less, the measurements as given can be slightly altered to suit conditions. A DOOR-KNOB HINT A scheme devised by Mr. Irving D. Banks is shown in Fig. 86 which will save the stooping pr groping to turn the door knob of a door placed at bottom of a dark, steep or winding stairway. It may be of service to others. It is extremely simple to make, and the cost is prac- tically nothing. Take a piece of brass about 1 / 32 or Vie i ncrl thick, y 2 inch wide and 3 inches long. Bend it around the shank of knob, leaving one end projecting. The size of this clamp must be slightly less than the size of the shank, so the bolt will draw it tight. Punch holes through brass where it meets, and also a hole through the long end or ear. Bolt clamp to shank 108 HINTS FOR CARPENTERS so ear is horizontal and connect wire from end hole in brass to end hole in a wooden lever, which should be about 6 inches long and screwed to the door, first putting a little block of about % inch thickness between lever and door in order to give finger room. /VOOD SCREW » M EVER, o -WIRE »CLAMP Fig. 86 ABOUT HATCHWAYS Carpenters are often called upon to fix hatch doors, and the usual practice has been to cut a recess in each door so as to make a hole in the middle, C (Fig. 87), for the rope to go through when both doors are closed. The rope, however, does not go down in the middle on ac- count of its moving along the drum as it is being unwound HINTS FOR CARPENTERS 109 or lowered ; hence it is necessary for any one on a lower floor to go up stairs and put the rope through the hole when it is to be lowered and the hatch doors on the upper floors are closed. This causes a good deal of climbing stairs and also a considerable amount of swearing. Fig. 87 I have followed the plan of letting the rope come down, and where the hook at the end of the rope touches the door, to cut the hole there. This will be seen by the above sketch. As can be readily seen, the rope can be let down through a number of closed hatch doors without its being caught. "DEAFENING" FLOORS From a French journal we gain another suggestion 11" HINTS FOR CARPENTERS for a method of "deafening" floors, attributed to General Loyre, who proposes, instead of loading the floors with plaster, to fill in the space between the boarding and the plastering of ceiling with shavings which have been ren- dered incombustible by dipping them in a tub of thick whitewash. As it is known that soft substances inclosing air spaces form an excellent non-conducting material to sound, it is thought that the shavings so treated will be found of great service, and it is said they are so incom- bustible as to add considerable to the fire-resisting prop- erties of the building. When it is desired to disinfect the space between the floor and ceiling, the shavings may be saturated with chloride of zinc, or the latter may be added to the lime wash. SELF-DROPPING BEAMS In brick houses the beams should be cut at the ends as shown in Fig. 88, so that they will fall out easily without overturning the wall in case of fire in the building. This makes the insurance rate about 1 per cent, less than if the beams were cut so as not to be self-releasing. FLOOR ON CONCRETE Fig. 89 shows a method of nailing down a wood floor over a concrete cellar floor. The flooring is nailed to 3 X 3-inch sleepers of trap- ezoidal form, about 12 or 14 inches apart, as shown in HINTS FOR CARPENTERS 111 the illustration. These sleepers are embedded in the con- crete so that the tops of the sleepers and concrete are even. When the sleepers are made in this form, they are not likely to work loose ; as an extra precaution they should be nailed at the ends and every 6 feet of span. -*s£Hw* *-
