I've been checking out the prices for bar or wire lead free solder. Cheapest I've found is still over $20 per pound. I've got about 200 lbs of lead sheeting, plumbing pipe and stick on WW which I believe is close to pure lead. To make a 20 to 1 alloy will cost over $200 just for the tin. I know you pay to play but are there any other sources for tin that may be cheaper?
