In2, One thing I learned about the old machines and that is they have a mind of their own.
You can work with them but never against them.
Take the case of the average belt driven lathes of yesteryear, with bronze bearings in the headstock.
I learned from fellow workers in the early days of my career, that the parting tool was a nasty vicious tool that would dig in and get the job to ride up on it, and so smash it to bits at the drop of a hat.
Untill one old guy showed me that parting from the rear tool post with the tool upside down worked like magic on these old machines.
Never looked back after that.
