13-030.jpg (27518 bytes) GRAVES PERFORMER. Take the guess work out of shaping and sizing cabochons and faceted stones. Simply assemble the proper cam, turn the handwheel and the preformer will guide the grinding of the stone to the precise size and shape of the cam. Easily adapts to most grinding and faceting machines (only known exception is the Diamond Demon). To save time - stack up to four cabs together and preform all at the same time.

Additional precision molded nylon cams are available as a package, see Item No. 13-031.
