They are quite similar to AM hubs except for the hex which is a 7/16 hex.
We HAD two easy process options for making these.. HAD being the operative word.

Normally we could have set these up on our Haas CNC milling center OR our Haas CNC toolroom lathe .... but alas our shop at El Camino College is undergoing "reconfiguration" to make room for a new Haas VF-4 vertical milling center and a Motoman industrial robot station [which is being installed inside of an 'Ultimate Fight Cage']. With most of our CNC machines offline in the shop we did the hubs the old fashion way on a manual lathe and a Kent mill. The hex broaching was done on a hydralic 50-ton press which proved great exercise for those involved.

Hopefully next year AM will offer these HEX hubs in a 7/16 size and save us the trouble of making them.
