Thank you John for that. The way I have set it up is very similar. I thought I was missing something, but your way is one for the memory bank.
I am working on a 2" tube, and gripped one end in the chuck, and using a level and whatever was handy propped the tube level, then moved the steady tight up to the chuck and fixed the lower fingers, slackened off chuck moved the steady into position, fixed top finger, then tightened chuck.
Thanks again
John
