I searched but didn't really come up with much. Im pretty sure allot of people on here scrap rotors/drums as they are pretty heavy and should be easy to come by. Just a few questions so i can get in to it soon with a few local shops im going to try work something out with. Do you bring them a pallet or heavy card board box and let it stack up ? Or just go by weekly/bi and grab what ever you can ? Just trying to get a general idea. I know im going to need a considerable amount because cast iron/steel in hawaii is only 0.3$/LB so i would have to build up quit a bit before making any cash. Pretty much all the shops i know of i know atleast a few people and no one collects their scrap. I think i should make out alright
