Same problem as before, but I now know the correct names of the parts. The quill/leadscrew assembly from the tailstock on my PM 3520 lathe are frozen, so that the whole assembly is inoperable. The handwheel won't turn the screw, so the quill will not advance. I was able to remove the quill/screw from the tailstock, but though the manual shows them as two distinct parts, they are stuck fast together. Since the quill is in the retracted position, it won't accept the live center, so the whole tailstock assembly is useless. Has anyone experienced this before? I guess I'll have to call their service dept tomorrow. Hope there is an easy fix, and I won't have to wait for a new part.
Edit: I solved the problem with a few judicious taps with a wooden mallet, but this is about the third time this has happened. The other freezes were undone without having to remove the quill, so each time it happens, it seems to get worse. I still would like to know if this has happened to anyone else, as I'll probably still call PM service dept about it. It's pretty messy to correct, lots of grease in there.
