A washer M, to takeup the wear, and a thumbscrew L complete the list.—3TWO HANDY CLAMPS The small clamps illustrated in Fig. 58, being of exactly thesame size and shape, are a very handy thing to have in theworkshop. To make them, select two pieces of machine steel just largeenough to finish to the size of the U frame of the clamp as shown,namely, 2^4 by \]/2 by y> inches. The two broad faces of eachpiece must be filed to as nearly a plane surface as it is possible to HANDY MANS WORKSHOP AND LABORATORY 53 get them, having each piece y2 inch thick. Test the surfaces byplacing the pieces together, and carefully mark the two faceswhich fit the best with a small file cut on one edge of eachsurface. The two pieces are now to be sweated or soldered together,. B Ji Fig. 58—Two handy clamps having these two marked surfaces next to each other. This is donein the following manner: Heat the pieces until solder will meltupon them, then cover each of the marked surfaces with solderingacid and rub on a coating of solder. Place the two pieces with thesolder-covered faces together, and clamp them firmly. Heatagain until the solder runs together, then allow them to coolslowly. Upon removing the clamp you will find that the twoblocks of steel are firmly fastened together, making one solidblock. Next true up the edges of the block, making all angles right 54 HANDY MANS WORKSHOP AND LABORATORY angles. This gives you a neat block of steel 2^ by i/2 by Iinches. Be sure to make the angle between the sides which willform the back and the bottom of the clamp a right angle, so thatholes at exactly right angles may be drilled in a piece of workwithout removing it from the clamps by first drilling with theclamps in an upr
