H is a suit- HANDY MAN S WORKSHOP AND LABORATORY 165 able rest for the above clamp. Its shank I is turned to take theplace of the ordinary rest of a small emery wheel. By raisingor lowering the rest, the required clearance is obtained. Whenthe grinding is finished, the edge of the rest engages the shoulderK of the lower plate B, thus making it certain that each piecewill be ground at the same angle and length.—16 CUTTING KEYWAYS ON A DIE SINKER The accompanying drawing shows the way in which a diesinker may be equipped for cutting keyways in piston rods and. Fig. 147—Cutting keyways on a die sinker valve stems and drift holes in drill and milling-machine machinist knows that it is quite a job to drill, chip, andfile a keyway in a piston rod or valve stem. A device of thiskind has proved itself to be just the thing for such work, and itcan be made in any one-horse shop with very little cost. i66 HANDY MAN S WORKSHOP AND LABORATORY Fig. 147 shows the device and the way in which the work isclamped. Stand A is machined, and a dovetail is cut across itsbottom to fit the dovetail of the knee of the machine. Slide B ismachined to fit the top of A, and slotted crank disk C is attachedto shaft D. A T-slot is cut half way across the face of the disk Cto receive an adjustable crank-pin, which gives the slide B thestroke required for the keyways. Bracket E is attached to theside of the die sinker to receive a short shaft, one end of whichcarries pulley F, while the other end is connected by a universalcoupling to the shaft D. Belt G p
