Are there some of these thrust bearings that we can install on our manual lathes?? No boring big holes, etc., if I want to go back to original.

This is what I was taught to do and have done on all my larger lathes, but on the small SL it was a problem that needed more looking at if I was to use power on the screws, my first thought was I

Hello,Carl Aggreed! Backlash compensation was the first thing we learned in trade school when learning to operate the lathe. The same principle applies to most any machine tool, although theses days

This. Somebody wiser than I am tought me that me that you can't ever totally eliminate backlash on a screw and nut setup. You can lessen it so it is less obnoxious, but you can't eliminate it. So you

Hi Gang: As a toolmaker we learned to always turn the cranks the same way, usually clockwise. This has fallen to the wayside with ball screws and digital read outs. Carl.
