Hi! Just got switched over to digest - thanks, Bill - Great list!
I've been sneaking up on this CNC thing for a few years, and have
the electronic part more-or-less less figured out.
What I'm having a problem with is the mechanicals, specifically
whether to design and build a machine, or just buy an old CNC mill
and retrofit it. From the prices I've seen for accurate linear
bearings, shafts, ballscrews, and machining, the cost would be
about the same.(?)
Anyway, what I'm wondering about is maybe pouring linear bearings
around semi precision shafting. I've thought about babbit, and just
heard about this stuff called Moglice. Any ideas?
