I needed to add some weight to a wooden base. I'm always finding wheel balance weights on the road when commuting on my bike. Wheel balance weights are made of zinc, lead, or steel. Zinc and lead both have melting points below 500F, making them easy to cast with steel tools and a propane or propylene torch. In this video, I melt down some weights and cast them into a piece of half inch steel tubing, which I can later insert into holes in the wood base.
