The method is illustrated by Fig. 106, where A is a piece of flat wood, ¼ in. thick, 1 ¼ in. wide, and about 6 in. long; B is a small T square with one edge tapered off, "as shown; C is a paper scale, marked out as in Fig. 107, and pasted or glued on. Fig. 107 is reproduced full size.
The exactness with which the letters can be placed in position by means of this appliance will amply repay the time taken in making it.
Make a piece of the same shape as B, and see that when A and B are placed together they form a round rod, that is, B simply fills up A where it has been filed away. With a small square file reduce B to the shape indicated at E, and then with a small sharp chisel cut A in the same manner about 7/8 in. up. When A and B are placed together they form a square, which is for the purpose of holding the letter to be used. Now make a small screw with head-about No. 10 B.W.G.-and having done this, drill a hole through A, ¾ in. from the end, to allow the screw to drop through; continue it through B, but make it smaller than the hole in A, because, whilst the hole in A allows the screw to drop through, that in B requires to be tapped. Take care at this point-A is clean through, B is tapped. The screw D should be made a little shorter than C, but of the same diameter. A hole should be drilled for the screw to pass through, as shown; but in this case the hole in A is tapped. Continue the hole into B, but not quite through it, and then enlarge the hole until the screw will drop into it. It has now only to be driven into a haft, when it will be ready for use.
