I figured out a quicker way to prep rotor housings for p-ports.

You need to get rid of all this stuff on the out side of the
rotor housing so the sealing blocks fit better.


I had the idea to use a pneumatic one inch belt sander. Harbor Freight
had one for $40. I went over there to buy one and the power went
off before I could pay for it. They gave me a 20% discount coupon because
the power went down for when I go back tomorrow.

I'll let you know how it works in a couple of days as I will have
ten rotor housings to clean up soon.
