I have compiled my cast-not-set class/theory notes, for your reference! The document contains some fundamental "rules" for employing this cheeky setting-in-wax technique. This theory is based on my personal experience, as I am well seasoned with this setting technique, and the guide outlines what "to do" and what to avoid when you're setting gemstones directly in wax for casting in place (in tandem with the metal of your choice). It also includes step by step instructions for flush setting small round gems into a wax ring model. I have also included a handy summary of the lost wax casting process which ensues once your wax model has been prepared!
