the deal is that i have access to a pile of scrap metal of various sizes, weight, and color. the problem is that i dont know how to figure out what is the good stuff. i guess to find out what is steel i should just take a magnet to it right? next, i need to find out what would slide well andwhats the hardest so thats where you guys come in. . .
does anyone have any tricks on how to find out what metal is hardest or best to slide? like maybe scratching it with something, what color is what metal, or how it sounds when you tap it?
greatly appreciated if anyone can unleash some wisdom because i have to jump on this asap
