Faceting the top of a Cabochon

Greetings happy thanksgiving! i am looking for information/instruction on how to facet the tops of Cabochon I currently facet using a nice custom built machine and there is a lot of information about faceting gems. However i have come up dry when searching for more in depth education on this process or even cut plans.

Thank you in advance
Chris

Here are a few IGS articles that discuss cabochon cutting techniques:

Lapidary Fundamentals: Cabochon Cutting.
Advanced Cutting Techniques for Cabochons.
Cabochon Carving Tools and Techniques.
This article on managing inclusions in transparent gems deals mostly with cabochon cutting.
This article on dopping techniques has a section specific to cabochons.

I hope these can help you.

It has some Good information but not quite what I am looking for
