I had myself in a little panic right before I posted that, "tell me I don't have to spend another $300..". After reading for about an hour on some other sites I see there's quite a few ways to grind them, that I already have. I like the diamond blade on the side of the grinder stone trick, that only takes another 1/16" of shop space. But here's another ?, do you have to worry about contamination when you're welding mild steel? or is it just on stainless, alum, etc.? (for shop repair stuff, I'm not trying to pass any tests)
