Of course, I have kept a list of the above forum locations; and I am curious
if anyone happens to know the present cost of setting up that sort of CNC
system for the cores in something like a Vari-Eze.

Along with Practical Machinist's, and Chaski's Home Machinist, CNC
sections, add for homebrew CNC:
CNCzone.com

A group to monitor, if you are interested in developing a homebrew CNC
machine to mill or cut out your next skychaser.
The cost depends on your own vision of the machine, the task, and your
expected production.
