Ive started selling junk metal on the side recently and was wondering if anyone had any tips or tricks for me? I know the basics like copper, aluminum and brass bring great money but does anyone know about foundry steel, prepared and unprepared steel? Ive been looking around the net and info seems hard to find. Ive been thinking about buying a chop saw to condense my loads and get better money? Would a concrete saw be ok for cutting thru car frames and such?
