I wonder if anyone has devised a cnc hobber on the cheap?

Yes, I have seen that, and I really want to buy it, but the only site the castings are available from is in the UK and the thing is expensive enough already.

A CNC hobber is called "CNC mill + automatic indexer", I believe. To my knowledge (a few weeks of on-off research) nobody has made a dedicated CNC hobber, although it should be easy to set up if you already have a CNC mill.
