Dick, I was looking at the 68 repair manual trying to find the minimum
thickness. I may be wrong, but I think they did not list a minimum
thickness. Instead, they just said that rotors should never be turned and
machined! They assumed that nobody will machine them, so they did not
publish a minimum thickness, or so it seems.
