I have picked up some lead from tire shops that I melt down into about 4 pound ingots. I agree with bearclaw, I have a friend who ended up with about a thousand pounds of the lead from an old xray room in a hospital they were renovating. It comes in sheets that you can cut with a razor knife, then fold and break it. Lead of all kinds is getting really hard to find, since the scrap metal business is booming. A lot of the tire shops are reusing the lead when they can due to the quadrupling price of tire weights.
