Thanks for all the advise. So I started checking out the tailstock. After cleaning it and checking for burs I remounted it on the lathe. I put an indicator on the carriage and extended the quill as far as it goes, about 2.25”. I traversed the OD of the quill with the indicator by moving the carriage towards the headstock. Yea, I got a problem. Indicator reads minus .003. I’m assuming that the quill bore is concentric with the od of the quill. So the tailstock axis isn’t parallel to the spindle. I figure my next step will be to see if I have bed twist or if the issue is with the tailstock. Does that seem right to you guys?Just to expand on RJ's comment, you can check for twist by checking the runout at a number of z axis positions. I've done that on my lathe.
If you don't know the source of the problem you are just wasting your time with "fixes".
Does the tailstock quill have a lock?I traversed the OD of the quill with the indicator by moving the carriage towards the headstock. Yea, I got a problem. Indicator reads minus .003
Yes it does have a lock. No variation in reading between locked, unlocked.tho.Does the tailstock quill have a lock?
