In all reality, the reason for turning it is to clean up some pitting

There is a tool that was used on one of my 8 3/4 housings where some welding was done. Tubing sander or some such thing. Fits over the tube no need to rotate the housing.

Smooth as a baby's butt.

Also

The reason you can lift a car by the center of the rear end when it's NOT an 8 3/4.
