If you have a local source for hex shaft (preferably 0.500 Inch) for compatibility with Vex/AM parts, it would be trivial to machine that down to .500 round or any metric size smaller that you want to use for bearings.

We have an on-line metals warehouse nearby, and simply pickup all our hex shaft there.

Comment- 6061 is fine for most shafting. We normally use 7075 as its it's yield strength is much better (73Ksi vs 40Ksi).

My understanding is the ThunderHex was designed for teams who don't have access to a lathe (or don't want to invest the time on that project).
