A finished rear hub weighs 6.5 pounds. I wouldn't worry about getting a forging. You won't be able to get it forged close enough to the net size to see the forging marks when you are done anyway. A billet will weigh 51 pounds for a rear hub. You are just asking for a ton of grief. If you are really crazy, I may be able to find some of our old forgings around here.

When the rear hub breaks it snaps at the root of the outer bearing (on the inboard side of the rotor flange). It is a catastrophic, wheel falling off, pants soiling event.

But in that moment hopefully there's time to reflect that at least the right half-shafts are there and didn't break and next time buy hubs from Kirkham
Thanks for the info! I will post pics when mine are painted and assembled.

1/2 shafts don't help. The wheel falls off.

David I just checked where I buy small amounts of metal so the price per pound is high. 17-4 from them is about $7.00 per pound..... It would brake my heart to have to turn 40 plus pounds into chips per rear hub. That a lot of money turned into chips.

I wasn't worried about the forging marks. I thought they would be a little stronger and be easier to machine. Also the amount of chips flying would be a lot less.

If you have some forgings that need machining I would be interested.
