Hello- this one really has me stumped and to this point I have used only homemade lathes for turning and this is my first experience with a factory-made lathe of this brand.
Okay; when I turn on this lathe, the Jet JWL 1220 with bed extension, it turns out of round in spindle turning no matter what size the spindle. Making the centers meet, I see that they are out of center by about a millimeter or less, which has never been a huge problem with any of my other lathes. The only difference I can see in the configuration of the lathes is that the tailstock center is not a dead center but some kind of live one.
What could possibly be causing this problem? I make sure that the ends of my stock are square and center the turning piece in the lathe, so just what could be causing it to turn out of round?
Thanks in advance for any ideas.
