7x14 Chuck jaws are binding after mounting the chuck to the lathe.
Hi,
I have a 7x14 minilathe with a 4" 3 jaw chuck that came with the lathe.
The chuck is mounted to the spindle by 3 8mm studs. The chuck registers onto a 72mm boss on the spindle plate.
When I tighten up the 3 mounting studs, the chuck jaws bind and lockup so that I can't move the jaws with the chuck key. If I back off the nuts on the 3 mounting studs, the chuck key moves the jaws fine. It seem like when the mounting nuts are tightened, the chuck is being warped. That said I wouldn't have thought that was possible.
Has anyone experienced this problem before? And have a solution?
Cheers,
Peter
