gunmontey thanks for that vedio good info.
Going through the WW's there is some that are mark with MC & #'s . Some are harder to mark with the side cutters then others would they be lead also???.
I don't think they are zinc.
I have come across a new product for my zinc wheel weights... Making pyramid anchors. So for I have orders for 2. Selling the zinc for $1/lb and a case of beer for casting. Making 2 9lb anchors with stainless eyebolts cast inside.
I was planning on using a plaster mold. After reading the other thread about melting zinc, I am just not sure what to use for a pot. Aluminum?
