Figured someone here probably has the scrap thing figured out, so any tips for getting the best return on the scrap pile? I've got several cubic yards of scrap (cleaning out an old hvac/tinsmith shop), so figure if it would pay better I'd sort it a bit. Obviously separating the metals is a good thing, but what about tube and structural steel from sheet? Cast iron? Stuff like fluorescent light fixtures go in with the sheet? What about nice forged aviation snips that are rusted beyond hope? Buckets of rusty screws and nails? Electric motors? Gas motors? At what point does sheet become plate and should be lumped with the structural? Unsalvageable bottle jacks? Spools of rusted welding wire?
If you can't tell, there's more than a little bit of everything in there. Including a 48" diameter saw blade which I assume came out of a sawmill (which I'll be keeping, along with a bunch of other interesting/useful things).
Thanks for the help!
