The Tool Rest





This is the most difficult part of the whole lathe, as it must be rigid, and so constructed that it has a revolvable motion as well as being capable of a movement to and from the material in the lathe.

Select a good 4" × 4" scantling (M), 14 inches long, as shown in Fig. 243. Two inches from one end cut a cross gain (I), 1½ inches deep and 1 inch wide, and round off the upper edge, as at 2.

Then prepare a piece (N), 1 inch thick, 8 inches wide, and 10 inches long. Round off the upper edge to form a nose, and midway between its ends cut a cross gain 4 inches wide and 1½ inches deep. The lower margin may be cut away, at an angle on each side of the gain. All that is necessary now is to make a block (O), 8 inches long, rounded on one edge, and a wedge (P).

A leather belt or strap (Q), 1½ inches wide, formed into a loop, as shown in the perspective view (R), serves as a means for holding the rest rigidly when the wedge is driven in.
