I was wondering about machining lead myself.
Plus one for thrift shop pewter. I have learned how to tell if it's pewter or not, but it usually says on it. I was in a good will in Wichita a few days ago and there was a bowl that weighed at least 10-12 ounces for $4.99. I should have bought it, I suppose, but I have quite a bit already and as stated, a little will alloy a lot of lead.
