Few pics of a project I'm working on to break up the misery or paint, bondo and rust removal on my V-8 SBC conversion. I'm going to do the sheridan body work on my car and found these wheels which I liked.

The problem is the wheels are 10 inches wide with an offset of 2 inches. In searching the web site it seems that most people with this combo have gone with 3" spacers. This seemed like it would put a lot of force on the bearing and I still would not have many other rear brake options. So.... I found some rear 928 hubs on ebay. the bearings are much larger: 85mm diameter and 47mm wide (versus stock 75mm diameter x 37mm long) and this would provide me with other 5 lug rear brake options. So off to the barn.



First, put a piece of 5 inch 1.25 inch wall DOM(Drawn Over Mandrel steel tubing) in the lathe.

Cut off everything that didn't look like rear hub.........

Cut the sides off for the 928 brake shoe backing plates.

And was left with new hub that could hold a larger (928) bearing. Sure is purty at this point. I'm finally getting the hang of turning parts. The 2 critical dimensions in this hub are the diameter of the bearing bore and the length of the bearing bore back to the its front which is a large circlip. I was confident I got these within 1/1000. Everything else can be done in hundreths.
