Make no attempt to reduce the material along side the wear mark in th
middle of the combustion side, where the sides seals wear off the most
material. Wear over .006" should
indicate a regrind and or lap job. Engines will run perfectly well with
more wear but start to use oil and loose compression.
Just use the same time and pressure everywhere, and all will be well. Use
a propane torch on the abrasive face to release the pad glue. This was
standard operating procedure in body shops around for years. Now the hook and
loop stuff and pre-glued pads are taking over. But nobody makes silicone
carbide in hook and loop (yet).
Make sure the DA is set on orbital instead of grind. The DA in this case
means Dual Action.
I didn't know that for years and used one every day. I thought it was a
brand name.

Lynn,
Having looked at that wear area on the end housings, I was wondering if
this was in excess, could we have the surface ground and then
re-Nitrited?
The whole process wouldn't be anywhere near as expensive as new
housings
