I have been collecting WW, tin, plumbers lead, and linotype for 50 years. Last summer I got almost 800 pounds of lino tailings from an old printing plant, they are full of slag and trash but it is good alloy when I get it refined. Talk to your dentist, they still use lead foil as sheathing on x-ray film, also your hospital x-ray. Talk to your plumber, if you live where there are old homes there may still be lead drain pipes that he pulls out when he does work. My plumber was replacing drains in the elementary school two weeks ago, the cast iron pipes had lead seals in the flanges that bolted the sections together, he gave the seals to me. Check your local scrap metal dealer, pay for the scrap, as long as he makes a profit without having to handle the scrap he will probably sell. Take a box of donuts with you, even if he doesn't have anything you want, leave the donuts and your name and number.
