Would this one be rigid enough? It is a 42 inch throw facing and boring lathe weighing 10.5 tons without the face plate shown. There is no tail stock on this type but another face plate or a precision steady can be mounted on the rear.
My son and I are just fettling and setting it up in our collection.
I am just joking because I have no intention of machining a crankshaft in it.
I have trued up several Model A rear flanges in another of our lathes, after straightening the cranks in a press.
A crank grinder is something missing in our collection of machine tools.
