Just saw that, and thought I would look, kind of an interesting site. One thing I want to mention. They list a few CNC machines that they guarantee can do head work.
One of the brands they list is Fadal Vertical Machining Centers.
The shop I work for... has 5 of them. Best VMC's ever made. By chance, I dont suppose anyone here has a copy of their software, CAMplete, that I could have to try out? It looks interesting, and may be applicable in the shop I work for. I'd love to see how it works with some of the stuff we have to build.
