Making Black Powder with a Ball Mill
2012-7-17 · Making Black Powder with a Ball Mill. Just so you know what''s going on. This is me in my backyard. I am using a homemade ball mill I''ve had for 20 years, and Skylighter''s ½" antimony-hardened lead balls. Check out my fancy-dancy mill jar! It''s a one-gallon plastic mayonnaise jar stuck inside a large coffee can for reinforcement.
