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 of you book 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.?
