CHAPTER V
THE WORKSHOP
ОглавлениеIf you have a place where you can build a workshop you will find one described in Part III. If not, try to find a well-lighted shop, both on account of your eyes and your work; one that is dry, or your tools will rust and your work be injured; and one that can be heated, for there will be no time you will wish to use it more than on cold, stormy days.
As a rule, an outbuilding is better than a basement or attic, other things being equal, because a basement is liable to be damp and dark, and an attic is bad about carrying materials and finished work up-and down-stairs. Noise in the top story of a house is usually more disturbing to the occupants than noise in the basement; but all these conditions vary in different places.
Have a lock on the door of your workshop, partly to keep small children from getting cut if they should come in without leave, and partly to prevent your work being interfered with in your absence and the edge-tools used for various domestic purposes by your feminine relatives, who might, in their innocence, mistake your best gouge for a tack-puller or the quarter-inch chisel for a screw-driver.
Of course you will have overalls and jumper or a work-man's apron made of denim, ticking, or some strong cloth. If you use an apron, have a pocket in it. A small slip of a pocket on the outside seam of your overalls above the right knee is also useful for holding a rule. When you have a long job of dirty work before you, a good way is to change your clothes for any "old duds" that you may have. This saves your clothes, and in warm weather is more comfortable and healthful than to wear overalls.

Your shop can be all fitted up for you by a carpenter, but it will be better, and better fun, to do it yourself. After the workshop itself is ready the first important thing is the work-bench.
The Work-Bench.—A very simple one (Fig. 37) will answer your purpose for a long time. When you become a pretty good workman and feel the need of something better (for a first-class bench with the best attachments is really a great help toward doing good work), you will still find this first simple affair very useful in some part of your shop.[14] There is no need of a bench being made of stock of exactly the dimensions given, so if you have a pile of boards and joists to draw from without buying, you can, of course, substitute other-sized pieces, provided you use stock heavy enough to make a firm bench. Heavier legs and top (front board) would be better, and in fact there is little danger of making a bench too solid.
Before beginning to work read carefully Marking, Square, Rule, Saw, in Part V., and look up any other references.
The design is for a small bench, 5' 10" long, 2' wide, and 2' 6" high. A larger one can be made on the same principle.[15]
You will require for stock:
1 piece of 3" X 4" joist 10' long.
1 | board, | 7/8" | thick, | planed, | 12" | wide, | 12' | long. |
1 | " | " | " | " | 10" | " | 12' | " |
1 | " | " | " | " | 10" | " | 6' | " |
1 plank, | 1½" | or 2" thick, | planed, | 5" or 6" | wide, | 2' 9" long. | ||
1 strip, | ½" | to 7/8" thick, | 3" or 4" | wide, | 15" long. |
Pine is good, and almost any cheap wood can be used. Hemlock is not very suitable, unless for the legs. Spruce is cheaper than pine or whitewood, and can be used for economy, but is prone to warp and twist and should be thoroughly nailed.
First make the legs and fasten them together. To do this, take the joist and lay it on two boxes or old chairs (Fig. 38), which you can use temporarily for horses, until you make a pair. See whether either end is cut off squarely. If neither is, mark a line by the square a short distance (perhaps half an inch, according to the condition of the end of the joist) from one end, on one side of the joist. Carry this line around the joist by applying the square to each side successively, and saw off the waste end with the cross-cutting saw. Having one end square, measure from that end 2' 5" and mark a line around the joist as before. Saw this piece off, and using it as a measure (but not as a square), mark and saw off three more pieces. These are for the legs.
Fig. 38.
Fig. 39.
Fig. 40.
Fig. 41.
Fig. 42.
Next, from the short 10" board, mark and cut off two pieces 1' 10¼" long in the same manner (Fig. 39), seeing first that the end from which you begin to measure is square. You do not need to mark the under side of the boards, but only the top and the edges. Now square a line 1" from each end of each of these short boards, and start three nails on each of the lines by driving them nearly through the board (Fig. 40). (See Nailing.) Next, place the end of one of these boards on the narrow side of one of the legs, and, holding it firmly in position, nail it securely to the leg. You must take pains to keep the leg and the cross-piece "square." Nail only one nail first and then adjust, testing with the try-square before driving the other nails (Fig. 41). Then nail the other end to another leg, and repeat the process with the other board and the remaining legs. This will give two frames like Fig. 42.
Fig. 43.
Fig. 44.
Fig. 45.
Next, fasten the sides to the legs. Take the 10" board and mark and saw off two pieces 5' 10" long in the same way as before (Fig. 43). At distances of 7" and 12" from each end of each board, mark lines across the side with the square and start nails between these lines (Fig. 44). Then, fitting these lines at the outside edges of the legs, nail the sides securely to the legs, as shown in Fig. 45. But drive only one nail through into each leg at first, until you are sure that the frame is coming together square and true throughout. Test the angles with the square. Stand the frame on as level a surface as you can find and sight across the top endways and crossways to see if either corner sticks up or down. If the top is not true, twist the frame enough to make it so, which you can easily do if you have but one nail in each corner. When the top is true and the legs at right angles, drive in the rest of the nails (Fig. 45). Be sure to test the top for winding, as just said (see Part V.), rather than to trust to the way the legs stand on the floor. Floors are often uneven, and the legs may not be cut exactly the same length. Make the top true and the legs can easily be made to fit the floor afterwards. The piece of 10" board left over you can fit to slip in between the sides, as in Fig. 45. If you nail through the sides and top into this piece, it will stiffen the bench. In making a long bench after this pattern, it is well to insert a few pieces of plank or joist between the sides in this manner.
Next, put on the top. Cut two lengths of 5' 10" from the 12" board. Lay them in position, square lines across as guides for the nails (as before), and nail them down to the legs and cross-boards. Also drive carefully a few nails at the edge down into the sides of the bench. Sink all the nail-heads well below the surface (as much as 1/8") with the nail-set (see Nail-Set).
A better bench can be made by using a plank (say a 2" plank, planed) for the front of the top (Figs. 46, 47, 48). This bench with plank front is much better than the common carpenter's bench just described, and the difference in expense is but slight. It is easier to do good work on, as it is stiffer, steadier, and much better to pound on.
Fig. 46.
Fig. 47.
Fig. 48.
Of course a thicker plank can be used if available. Hard wood is best. Maple is excellent for a bench-top. Take particular care to select a good sound plank, from the centre of the tree if you can (see Chapter III.), as straight and free from winding as possible, and have it planed so as to be straight and true. This can easily be done at any properly equipped planing-mill.
To make this bench with a plank in front, you can proceed exactly as with the bench just described, except that the front legs should be as much shorter than those at the back as the plank you have is thicker than the 7/8" board used for the top of the bench just described. That is, if your plank is 17/8" thick the front legs should be 1" shorter than the back ones. Pieces must be cut out of the cross-boards in order that the top may be even (Fig. 46).
The simplest way, however, is to make the bench just like the preceding one until you come to the top. Then, after putting on the front plank, raise the back top-board to be flush with the plank, instead of lowering the plank to be flush with the board. You can do this by putting small pieces of board of the required thickness under the back part of the top (Fig. 47).
Some workmen prefer having the back board of the bench top lower than the front by an inch or so, with a strip fastened on the back, and sometimes at each end, so as to be level with the top of the front plank, thus forming a sort of tray (Fig. 48) where tools, nails, small bits of work, etc., can remain when in use, keeping the front plank clear for the actual operations. The work, if large, can be rested on the back strip as well as the front part, both being on a level.
The bench can be all filled up underneath with shelves, drawers, cupboards, compartments, or in any way that you wish, but at first, and for a simple bench like this, it is as well to have only one shelf, as shown in the frontispiece. You can easily put this shelf in after the bench is put together. You can tell better whether you want drawers and compartments after you have worked for some time and wish to make a more complete bench.
A nice bench should, of course, be built independently of the shop—that is, be complete in itself, so that it can be readily moved. But a common bench can sometimes be best built against the wall, using the side of the building to support the back. Sometimes one or both of the ends of the bench can be advantageously carried to the walls of the room, thus requiring legs only in the middle or at one end. But such arrangements are not to be advised if you are likely to wish to move the bench before you have used it enough to pay for making it.
Fig. 49.
Figure 49 is merely suggestive. The process of construction is the same as already shown, except that you omit some of the legs and the back side-board, a saving sufficient to allow you to use a plank for the front of the top. As the floor is likely to be uneven, you can first saw the posts a little too long, stand them in line, stretch a cord or a chalk-line (see Chalk-Line) along the line of the front edge of the bench at the proper height for the tops of the posts, cut the posts off where this line crosses them, nail on one end of the cross-boards at right angles, and then fasten the other end to the wall-studding, sighting and testing to have the top straight and true, as in the case of the bench already described. If instead of vertical studding the joists of the wall run horizontally (as is often the case), you can easily nail cleats on the wall if there is no horizontal timber at the right height to nail to.
Fig. 50.
Bench-Vise.—The kinds shown in Figs. 50, 56, 57, though not as good as some more improved forms, are in common use by carpenters, and will answer your purpose very well for ordinary work—until you get to the point of building a first-class bench.
At a distance of about 14" from the end of the bench and in the middle of the side board mark the point a (Fig. 45). Bore a hole at this point (see Boring) if you have a bit a trifle larger than the screw of the vise. If not, using this point as a centre, describe a circle (see Compasses) with a diameter a trifle greater than that of the vise screw, and remove the wood within the circle (see Boring and Paring.) Now take the piece of 1½" or 2" plank which is to make the movable jaw of the vise, and mark a line lengthways along the centre of each side (Fig. 51). At a distance of about 8" from one end mark a point upon this centre line and make a hole for the vise screw as before. The nut for the screw must now be fastened in position on the inner side of the bench, the vise screw passed through the movable jaw and the side board, and the handle plate fastened upon the face of the jaw.
Fig. 51.
Fig. 52.
You can now open and close the vise by the screw, but the movable jaw needs to be made steady and the end projects above the top of the bench. Screw the vise tight together and slide the movable jaw around until it is in the position shown in Fig. 52, when the centre line on the back side of the jaw will cross the edge of the leg a few inches from the floor, according to the width of the jaw and the degree of slant given it. When the jaw is in this position, mark from the back side the lines indicated in Fig. 52, and saw off the projecting ends of the jaw by these lines, which will give the shape shown in Figs. 37 and 50.
Fig. 53.
Fig. 54. Right.
Fig. 55. Wrong.
Next take the small strip, and marking points upon its side as shown in Fig. 53, bore holes with a 3/8" or ½" bit. Screw the end of the strip to the edge of the movable jaw (being careful to get it at right angles with the vertical edge of the jaw), as shown in Figs. 50 and 53 (see Screws). Just above and below where this strip crosses the post of the bench nail small blocks (a trifle thicker than the strip) so that it will pass easily between them. Cover these with a longer piece, making a slot, as shown in Fig. 53, through which the strip can slide freely. If the two blocks are no thicker than the strip, you can put pieces of paste-board between them and the post to make the slot wide enough to let the strip slide through freely. Fit a pin or piece of dowel to the holes in the strip. The use of these holes and the pin is to keep the face of the jaw approximately parallel to the side of the bench. Contrivances for this purpose can be bought. After the jaw is all fitted, bevel or round the edge on the face side at the top (see Bevelling), and you can also bevel or round all the front edges if you wish. The vise is now in working order.[16]
Fig. 56.
Fig. 57.
The important point with this vise (and in fact with any vise) is to have the inside surface of the jaw parallel with the surface of the side of the bench, so that the wood will be pressed equally at all points, else it will slip just when you wish it to be securely held. Be sure that the vise is not open more at the top than at the bottom (see Figs. 54 and 55).
Fig. 58.
Fig. 59.
The holes bored in the side of the bench are to support the end of a long board (Fig. 50).
If you cannot afford to buy a vise, or have to work where there is none, there are a number of makeshifts with which you can get along quite well, though not as rapidly or conveniently.
Fig. 60.
Carpenters often nail a piece on the side of the bench (Fig. 60), which holds boards for planing fairly well, for common work, but tends to bruise the ends of the boards a little against the cleat, and requires a knife, or something, driven in at the other end of the boards to hold them with any degree of security. Another cheap substitute is shown in Fig. 61. This holds boards of regular sizes quite well. Thin pieces can be held tighter by wedging, as shown.
Fig. 61.
Fig. 62.
Fig. 63.
Another simple contrivance, and more of a vise, is easily made by boring a couple of holes in a board, say 6" wide and 12" long, and screwing it loosely to the side of the bench (Fig. 62), making the holes in the board larger than the diameter of the screws so that it will be free to play. By inserting the piece to be held in the end and double wedging the opposite end (Fig. 63) the piece will be held fairly well (see Wedges). For thin boards, blocks can be inserted to make the jaw parallel with the side of the bench. An upright vise made on this principle is often used to hold saws for filing.
If you can find an old wooden hand-screw, you can use one jaw (sawing off the ends if necessary) for the nut to go inside of the bench, leaving the other for the movable jaw, using one screw to tighten or loosen the vise and the other to keep the jaw parallel with the side of the bench. You will require no description to contrive something of this sort. Vises on somewhat this principle can be bought, attachable and detachable at will.
The jaw in Fig. 64 can be hinged upon the strip at the bottom and the latter fastened to the side of the bench. The jaw can then be tightened or loosened by the screw. This gives a square grip only when the jaw is vertical (Fig. 65). You can put in blocks, however. The longer the jaw the less objectionable the slanting grip becomes, of course.
Always try to devise some such expedients, which you can think up for yourself, when you are without the regular appliances, for even a poor vise is better than to hold pieces in the hand or to push them against chairs or tables or the wall.
Fig. 64.
Fig. 65.
For nice work by far the best vise of moderate cost is that shown in Fig. 143, which has been in use for a long time by wood-workers of the better class.
There are a number of excellent iron vises (some with jaws of wood, and also with an "instantaneous grip"). Some of them are admirable, but quite costly compared with the common screw.
You can work quite well with a good-sized common iron vise by fitting wooden blocks or leather or rubber to the inside of the jaws, to save marring your wood-work, though a regular vise for wood is much to be preferred.
Bear in mind when doing work that requires to be held at unusual angles, or in fashioning odd-shaped pieces, that you can usually get the angle or position required by a combination of hand-screws or clamps with the bench-vise as suggested in Figs. 66 and 67.

Fig. 70.
Bench-Stop.—You must have something on the forward end of the bench-top to push your work against for planing and other operations. A simple and good way is to use one or two stout screws (Fig. 68). These can be screwed in so as to project about a quarter of an inch, which will answer for the greater part of your work, and the height can be changed when necessary with the screw-driver. The heads of the screws will be sharp enough to hold the work, and a stop of this kind will answer your purpose very well for common work. The wooden stop (Fig. 69) has the advantage of not making any nicks in the end of the wood, which is important in nice work, such as furniture, but for common work screws are just as good, except that, as they are left permanently sticking from the bench, you may dull your tools against them or scar your work. This applies to a common bench. Of course for a really nice bench with a tail-screw the regular stops should be used (Fig. 143).
Fig. 71.
Carpenters sometimes nail a small piece of board, with a V-shaped notch at one end, to the top of the bench to hold boards or joist for planing on the edge (Fig. 70). Simply nailing a strip across the end of the bench (Fig. 71), and setting the nails well in, will do to push boards against for planing for common work.
Fig. 72.
Fig. 73.
Iron contrivances (which can be raised or lowered) can be bought for a small sum and are convenient for common work, especially for thin pieces. Sink them deeply enough in the bench-top so that when lowered nothing will project to injure the tools or the work.
The old-fashioned bench-stop shown in Fig. 69 consists merely of a square stick of hard wood, one or two inches square, fitted quite tightly to a hole in the top of the bench, so that it will slide up or down by a blow from the mallet or hammer. This stop will not damage the work or the tools. To make the mortise for this bench-stop, see Mortising. Take care to keep within the lines, so as not to make the hole too big. You can easily make it larger if too small.
Fig. 74.
Fig. 75.
The stop should fit tightly and should be set with a very slight slant toward the work (Fig. 72)—that is, the mortise should be cut slightly slanting. The stop should be of hard wood, such as maple. If the top of the bench is only of board thickness, screw cleats of hard wood on the under side to give more bearing surface (Fig. 73), or the continued pushing against the stop will be liable to get the hole out of shape so that the stop will slant the wrong way, when the work will be apt to slip or, in case of a thin board, jump over the stop (Fig. 74). If the stop wears loose in the hole, a saw kerf is sometimes made lengthways in one side and a bent piece of springy wire inserted, or a flat spring fastened on the side (Fig. 75). A loose stop can easily be wedged (preferably from underneath), and it is sometimes made loose on purpose, the wedging tightening the stop and at the same time giving the required slant (Fig. 72). An iron plate with teeth can be screwed on top of a wooden stop (Fig. 76), or a screw can be inserted (Fig. 77).
Fig. 76.
Fig. 77.
Fig. 78.
Two strips, like Fig. 78, can be nailed or screwed on the top of the bench so as to separate V-fashion (Fig. 79). Two wedges, like Fig. 80, can then be made of such a taper that when fitted between the strips their inner faces will be parallel. By tapping in the wedges on each side of the work to be held (Fig. 79), it will be securely fastened without injury. If the inside edges of the strips and the outside edges of the wedges are slightly bevelled, which you can do with a plane or a knife, the wedges cannot jump out of place. The best way to fit this contrivance is to make the wedges first, place them in position on the bench with the square sides inside (facing each other), and then fasten the fixed strips outside of them. Pushing the work tends to tighten this vise. This is much better for permanent use than the notched board shown in Fig. 70. If you have a good vise you will not often have occasion to use such contrivances, but they are sometimes useful as makeshifts.
Fig. 79.
Fig. 80.
The top of a good bench should be as true and as smooth as possible (see Plane and Scraper). Rub it with linseed oil, wipe it off with a rag, and after a few days give it a couple of coats of shellac (see Finishing).
Fig. 81.
You should place your bench so that when you stand at it you will face the light and not have it come from behind you. If it can come from the forward end of the bench and also from behind the bench, as shown in the frontispiece, it will be best, for a cross-light is often very useful, not merely that you may have light enough, but also that when testing your work with the try-square, straight-edge, and the like, any inaccuracy may be detected by the light passing through the crack between the testing tool and the work, and also when sighting by the eye alone. Fasten the bench firmly to the floor (and wall if you can) with screws, cleats, or L irons.[17]
Avoid chopping on the bench top or whittling it or boring holes or marring it by saw-cuts or chisel-marks. Do not use paint, varnish, or glue at the bench if you can help it. If necessary to do so, clean the bench-top carefully when you get through. Lumps of hardened glue will hinder you and deface your work.
Filing-Bench.—You cannot do much of such varied wood-work as you will undertake without having to do a good deal of metal work. It is a poor plan to do such work at the vise you use for your wood-work, or even at the same bench. It scars and defaces the wooden vise and the bench, and the particles of metal are bad for your wood-work and for the tools. It is much better to have another bench—if nothing more than a wide shelf or a box—for such work (Fig. 81). You will find suggestions in the illustrations.
Fig. 82.
Fig. 83.
An iron vise is the proper thing for holding metal. There are many different kinds at various prices, but one of the simple patterns will probably answer every purpose. If you have room for only one bench this vise can be put at the back part of one end.
A small vise can be made of a hand-screw, the hand-screw itself being held in any desired position in the large bench-vise, but metal jaws are better for working on metal. You can make a rough sort of vise for metal-work with a piece of stout board or plank (Fig. 82). Find a couple of pieces of iron with screw holes, as you can probably do in a pile of waste iron junk, and screw them on the board and the bench to form metal jaws. The vise can be tightened or loosened by means of a big screw or bolt; or the board can be loosely fastened in the middle and tightened by wedging below (Fig. 83). A screw with a handle to turn it by and a nut for the thread is better, of course. Another form, such as you will find in use by leather-workers, can be easily made (Fig. 84), and works with the foot, the connection between the jaw and the treadle being made by a strap or rope. You can make a vise in some of these ways that will answer quite well for most of the metal-work you will have to do for some time, although such contrivances are less reliable and less convenient than a regular iron vise.
Fig. 84.
An anvil is often useful and is sometimes combined with a vise. It should have a flat steel surface and also a tapering rounded (conical) point. An old flat-iron does quite well. You can easily find some way to keep it in position on the filing-bench. You should have some sort of anvil, even if nothing better than a junk of old iron (which you can of course find somewhere), for you will be continually wanting to straighten nails, bend wire, and pound pieces of metal. Try to find a flat plate of thick sheet iron—¼" thick if you can—to fasten on the top of the filing-bench (Fig. 81). It is very handy for many anvil uses, straightening metal and nails, and for much pounding.
Finishing-Bench.—Have also a finishing-bench (Fig. 91) if possible—if nothing more than a shelf or box—to keep the regular work-bench neat and clean for its proper uses, for even a skilful workman can hardly avoid making a mess when it comes to using paint and varnish.
Fig. 85.
Now, while there are many of you who can afford either singly or by two or three clubbing together to fix up a shop in first-rate style, there are also many who cannot afford even so cheap a bench as that just described. What can you do in such a case? Only one thing—patch up a bench out of whatever old stuff you can find. Patched-up makeshifts are not to be recommended, except in case of necessity, but when it comes to the pinch, and a matter of having a bench made of whatever old materials you can find or having no bench at all, by all means make one of boxes and anything that can be worked in. For of course the boats, skis, squirrel-houses, and so on, must be made!
