Let me qualify myself first: I do not know poop from putty about specifications!
Folks that turn shoes are not supposed to go beyond .060, for sure. I would wager that millions of drums were turned until they were clean without being checked for size. However, after getting to 12.060 most cars will be driven many miles causing wear beyond the "specifications." I suspect that many of us are driving our collector Fords well beyond the .060 lathe turning. I had a beautiful pair of 1935 front drums that measured 12.090. If I had a 35 Ford I would not have hesitated to use them. I took them to the scrap yard as I felt, after learning about the .060 limit, it would not be right to sell or give them away. I suppose that there have been many instances where a drum failed due to excess wear. But in my 65 years of working and/or hanging around automotive shops, I have never seen a drum that failed.
