It is going to be four operations to finish these wheels. Since I machined the radius on the back of the flange, there was not enough material to safely clamp on using the six jaw chuck, so I will have to finish the front on a face plate.
The front diameter started at 4.435 inches. I took it down to 3.800 in this operation. The wheels will finish at 3.750 inches. It looks like it would take forever to take off that much material, but with a sharp brazed carbide tool, I could take off .040 per pass. It only took about 15 minutes per wheel to make a big pile of chips!
I drilled the center out to 5/8 inch.
Finally, I used a single point boring bar to finish the center hole at 0.6875 inches.
