I think not, with the way it stopped the lathe. Maybe if the fixed piece
was allowed to spin before stopping the motor there would have been less
of a jolt.
Friction stir welding is a well-accepted process used to make axles and
driveshafts on auto parts. It may be a bit rough on standard lathes, but
the machines built for the purpose take it day in and day out.
