I just ordered tin from Roto-Metal in cut pieces of wire. Now my question is how can I tell how much to add? I ordered 3 pounds but using a 20 pound pot will this supply last a good while? I know that it depends on how much I cast but I've never added tin before. In my past casting I just used pure wheel weights.
I fear that I'm making this too complicated. In my younger, and simpler days I just went at it. Now that I'm hanging around you guys I'm trying too hard.
