While looking around in my garage, i seem to have collected myself a .. large quantity of disc break rotors.. They are pretty worn down, but there is still alot of metals in these.. I would think there are around 100+kg of scrap metall in that bin.
Now thinking.. Could these be melted and casted into usable shapes for the lathe or the mill.
Or is this steel/cast iron - what it can be, too tough to melt by myself in my backyard?
