Thanks again David. You know if you give them a little they will want more. So could you tell me and others were the drive hubs forged then heat treated and then machined. Or forged ,machined then heat treated and then ground to final dimensions.

I am scratch building and would like to machine my own hubs. Would 4140 pre hardened be a usable material to machine these parts from a solid chunk of shaft? I might be able to buy these cheaper than machining these myself but sometimes I get a lot of satisfaction out of making things.
