How to skim a brake disc in a lathe or a mill 

Not sure when you can feel it, but if there's more than 0.1mm runout I normally skim or replace the disk.

Yeah you do, if I have a disk that's the same bolt pattern, I just turn the front bit off the fixture off and machine the mounting face again. Thanks

@@maxfh768 Thanks 👍 Looking forward to more videos.

Could a 3 jaw lathe chuck not work? Got a lovely old gal (don’t know much of the details and jargon yet) but she’s running to tolerance. I was hoping to nearly use the chuck for direct mounting. I assume it would be necessary to use a dial gauge though to measure for runout? What is the acceptable amount?

I think when I measured them, I couldn't measure any difference in the lathe turned disk, and the milled disk had about 0.02mm variation in thickness
