Next was the centershaft, no question this would be stainless, and I cut this out of a 5 or 6 pound chunk of 2.5" 304. If you were wondering, ten hours were spent on this part alone. I had made 8mm drive cups out of air-hardening for use with the outrunner (Mike was out of them at the time) so those are now being used on the centershaft.
Lots of photos to come... keep watching
