How many times can a flywheel be re surfaced?

I use locktite and never a lock washer on a pressure plate or flywheel bolt. They can and will fail. When they do the end result is catastrophic. If you are using a washer it needs to be a hardened, parallel ground flat washer.

On certain pressure plates (the McLeod Borg&Beck/Long covers) you don’t use any washer. Ever. If you do, the cover will fail. BTDT.

Yes, this is a B&B pressure plate, so cutting the mounting surface simply moves the pressure plate fingers x thousands of inches away from the TOB, which can be taken up with normal adjustments. The mounting bolt holes in the flywheel are through holes, so no issue with those bottoming out.
My concern was more about the strength of the spinning mass.
