Polishing forcing cones in skeet tubes
We mount the tube in the head stock of the lathe and while it spins we use a small mandrel on a flex shaft Fordom grinder.
We polish 600, 1000, 2000 grit and then chrome rouge on a felt bob. Never dwell in one spot and make sure you are polishing the ramp. Keep before and after patterns so you can see what a major reduction in flyers does for patterns.
