I have rebuilt a lot of old tools .
I get tail stock and head stock real close.
The chuck a Morse tapper reamer. The re-ream the tail stock quill.? Now it is very accurate and is simple.?
Did like parts you posted on what say about it would have great 50 years ago.?
I would here storeys of casting of machine tools not age. You could see the casting with curve.? Hot castings to machine shop. I think have learned by now or maybe on mini lathes.?
