A friend and I were discussing some parts and the question was posed how we would individually go about making them. After thinking for a bit, I answered that I'd consider trying a swiss machine if the conditions were right. I've never tried this, but i'm curious. If I had, say, centerless od ground threaded stock of some sort, say Acme or Ballscrew type, is there any reason why one couldn't make one diameter for a bearing on one side, cut a keyway with live tooling, then feed the bar through to turn a similar cut and mill a similar keyway on the other end. Think Bridgeport mill X axis lead screw.
What do you think?
