Thanks for the links! I will have to keep an eye out...A benchmaster seems like the holy grail...Or something like that Barker. We already have too many sewing machines (all older than 45 years)...
Depends upon your skill and tooling. I would spin it pretty fast at 1500-1700 rpm and use roller tooling with lube. Anneal if/when needed - depends upon shape, how much you fuss over the metal, and its original temper.
