Lead Truck Wheels

I am using spoked wheels from Allen Models. I will be machining the wheels in three operations. I mounted the casting in a four jaw chuck. I tried to mount the casting so the outside edge of the spokes were running concentric to the lathe spindle.

Cast wheel mounted in the four jaw chuck.

The first operation will face the front of the wheel, drill a work hole in the center, and rough turn the OD to give me a surface to clamp on for the second operation.

Front face machined.
Drilling a 1/2 inch work hole in the center of the wheel.
OD machined concentric to the work hole.

I also machined a chamfer on the inside of the rim and on the outside of the inner hub.
