Re: Chuck & spindle nose flex?

Yeah I normally would use the tailstock but it's a test bar (for testing for parallel turning) so the TS would defeat the object, it looks long but it's actually only roughly 3x the diameter stickout which is fine. The broken handwheel is a pain, I have a metal one I can retrofit though. I really wa...

Re: Chuck & spindle nose flex?

Hi Dazz, cheers for your help, I think I have this sorted now. The rear bearing is, presumably erroneous, a tight press fit on the spindle.

I'm trying to ascertain whether the bearings are shot, or whether there's just a problem with the chuck mount. I posted about this over on the MadModder forum but someone suggested I ask here too.
