Shoulder Work

I cut a body to leg circle today and I routed into it to mount a aluminum
plate. The plate will act as a gear so the D shaft from the gear box will
have something to lock and turn the legs.

You can see the bearing bolts to the circle and the aluminum plate is under it.
The shoulder looks off right now because I need to sand it with my drum sander to true the circle.
It really is not that far out of round it's just the camera makes it look bad.
The bottom picture shows the gear box inside the frame. It's not bolted yet,
It's just for the picture.
