I picked up a vintage cold-handle skillet, cleaned it all up and love it. It is kind of thin compared to my usual cast iron, but a lot lighter to pack and carry. The only problem is the bottom isn't "flat", over the years it somehow developed a bow so it won't sit flat on a table or burner. Short of pounding on it, which I do not want to do, how can one straighten out the bottom metal? I don't know of any fabricators in the area with a metal shrinking wheel (such as custom car or motorcycle folks), so what are the alternatives?
Can I put it between to heavy pieces of flat steel and use my 8-ton press? Other suggestions?
