Still using a 5" Wilton vice I pulled out of a trash dumpster in about 1979. The shop mechanics said it was cheaper to dump it than to buy new jaws. Well, I called Wilton and they sent me a diamond cut set of jaws FREE. Companies use to do things like that you know!
But I'd still like to find a good deal on one. I THINK I want one with the Round cylinder. Machinist vice I think they called.
