I have one of those grinders from back when we cut 16 1/2" truck drums. There always hot spots that the cutter jumps over. I recently sold most of my heavy truck shop equipment and I am going to sell the rest of it at auction next Thursday. I will keep the drum lathe because no one turns truck drums any more. But with old obsolete stuff turning a drum is sometimes the best alternative. After running over the road trucks for 62 years I am going to be glad to see my stuff go. And hopefully I can find time now to work on my old GMCs.
