Things to consider when breaking items down

I only clean degaussing wire that's thick . I lose weight in plastic, I'm with you about selling transformers and electric motors whole . Maybe a large compressor but then like you said the steel would not lose after removing the copper . Sometimes I clean a big aluminum heat sink. I agree with your logic , I would rather be cutting rads or dismantling ewaste then doing electric motors or transformers . Come to think of it could prob do a computer faster than a large transformer . But that's just me .
