Drub brake specs for turning 12" drums?

[darkone]

Hey all, was really hoping to get my drums turned today, but the guy at the shop said they were too far gone.... thing is, les schwab said they were right on the edge. Bothing with this truck, as far as buyying parts goes, has been easy or accurate. So im turning to you guys (The professionals) to tell me what the min spec should be on the drum to turn it. I can't afford new drums and would just assume throw on discs if I had to replace the drums, but as I said my budget wont allow that. Anyway, any help would be appreciated.... I already have new shoes and hardware so I guess im going to put that together this afternoon. Thanks in advance for any input
