First off, I wanted to share a place to get metal for good prices. I was at Shapiro Metal Supply Co the other day for a different class and was wandering through their warehouses. They have an enormous amount of metal of different type, shape, and size. They are relatively cheap, and the people that work there are friendly. I bought a lot of metal and had it cut, and they cut me a 60%+ discount. Their website is http://www.shapirosupply.com/.
