Thank you for all the help. I had the shaft slipped the spindle I need

Chucks screw on and when the work is cutting it makes the chuck tighter
on the shaft. I have a pre-WWII lathe that has a 1x10 thread and the
chucks I found just screwed on and worked just fine. Only when going
backwards would it screw off.

Someone likely put a screw 'hole' for a center and a DOG. The dog is
attached to the center (or chuck...) by a tough screw and then to the
threaded / and covered screw. The dog must rotate.


A tail stock dog latches onto the tail stock with an arm and
cener/drill/etc with an angle and screw.

Suggest you look up some old manuals for how some of this stuff worked.

Old timers didn't have wood chucks or chucks other those made from wood.
