Well, I must have had The Force with me then. I've probably done 50+, from fractional to 150+ HP motors.I did use a support tube designed to clear the shaft, but fit closely. That way the lamination is supported. If the stack is allowed to "dish" at all, it will bite into the shaft, I would concur. I've just not had that problem. NEVER press against the fins/fan. They're usually riveted or peened in place, not cast that I've seen.
I was only offering that as a backup plan anyway. Turning it between chuck an center is the way to go.
In stead of replacing some of the mangled shafts that came in, we would cut off the end, drill it out to accept a stub shaft. 45° bevels all the way down, then weld up, turn and re-key.
