Finished Hub

All that's left to do is put in the bearings.

Rear hub

I started machining my rear hub from that piece of 6" 6061. I got it running true and bored the axle hole. Then I was able to put in registration marks so that I could attach the juice drum on the drive side. Sometimes i keep old broken parts in hopes that I can use them for something one day. In this case, this broken drum was perfect. I drilled out the alignment pins and machined a shouldered piece of aluminum that fit the bore of the bearing race on the drum roughly 1 5/8" while the smaller end fit the 1" hole I machined in the hub. I then drilled and tapped one of the holes so that the plate would fit tight to the hub as well as keeping it from rotating while I drilled the rest of the holes.  The other side will receive a 5 hole bolt pattern so that it can mate to a 15" car rim. Update coming.

Finished Hub

Finished, runs perfectly true.

The cup ended up cracking from the heat and the tungsten got bent some where in the mix.

Modified Hub

Had to make a radius shaped parting tool so I could part the hub on it's face or x-axis rather than the y-axis

Jig to align spoke holes and hold the removed section square and with an even gap. It worked well and after tacking run out was only +/- .005. Final truing done with dial indicator.
