I REALLY would not get too excited about min thickness on those girls. They have LOTS of meat and the pistons have lots of travel. You could easily DOUBLE the allowable cut and still be very, very safe. I have turned hundreds, if not thousands of drums and rotors in a previous life, all the way from little Fiats to over the road truck trailers. And I've relined shoes, and trailer brake shoes, and quite a few winch drums and such.
I know. I KNOW. It's the stated thickness. If this was a single width modern rotor, I would not go .001 under the spec
I still have an Ammco drum/ rotor machine. Turning the rotors, now 3 years ago, when I converted the diesel to 4WD
