Jon; OK, so you want to rig the Z drive to the quill, or the > knee?

Interesting point about the Bridgeport quill arrangement; the Centec one is more basic. I'll (attempt to) do some tests to see how well the knee moves this weekend. As mentioned, generally, it's just locked into place and left until it needs moving again (which can be months) so I'm not experienced in using it for actually dialling in a cut.
