Newly published in PDF format (PCs and Macs) by Gerald wykoff, this CD-ROM provides a comprehensive tutorial on cabochon cutting that includes such advanced techniques as "running a wheel" and "chopping" to assure proper curvature. New, easy dopping techniques are covered along with the tough subject of polishing. In addition, a full section is devoted to making an improvised DIY 1-station cabochon cutting machine with a few scrounged parts. The unit features quick-change on laps, a gravity water supply-drain system and other niceties expected in commercial machines.
