Can anyone give me a heads up on a machine for sale on eBay? Is it worth anything?

Hi Ray,

It looks like a lot of machine! At least the mechanical aspects sound good.

I'd have to wonder about a 1972 vintage cnc, though. Heck, I can remember 1972 like yesterday, when a 4 function calculator was the only PC around :D It would be nice to find out how a modern PC interfaces with it, what kind of software it runs on, etc. Might make a good retrofit candidate, though.

Looks like a nice machine, The vacuum table alone is worth big bucks! That is an old Allen-Bradley control, They never did manage to break into the CNC control market, in spite of trying. It looks like the Z axis is just point to point positioning and it looks like the PC is just for program download.
As Hu said it looks like a good retro-fit candidate and put a Z axis servo on it and a VFD on the spindle.
