    Lots of work but if you set yourself up correctly it gets easier. I use a 4 1/2" angle grinder for most of them. The larger ones like one I did today weighed about 90 lbs. It took the angle grinder and a sawzall to complete the cut of the copper coils.

    Don't forget to check for Al end caps and other parts made of Al, the magnet is still a great tool, Mike

    Now go beat the copper out of something, Miked

    Theres more money if you scrap fridge motors. Your advantage is that the metal dealers won't pay full 'electric motors' price for it, only shred price, as they don't know whats inside it.

    First, you need a licence to de-gas the fridges/freezers etc. You can either get one & charge extra for having the right paperwork,(ie, get the compressors for free) or scrap them down to metal & bypass the freon issue.

    To bypass the freon issue, you need to scrap the fridge motor into something unrecognisable as a fridge motor.

    So, buy your fridge compressor, about NZ$1.10 each. Cut it open & remove the motor & remove the copper wire from it.
    Put the heavy iron into one pile, put the rubbish out for collection, clean down the copper wire.

    Sell the heavy metal for NZ$250/ton. Light gauge metal for NZ$70/ton. Copper for NZ$7.50/Kg

    You will buy the compressor for NZ$1.10 (10Kg).
    Scrap it.
    Sell the heavy metal for NZ$2.20/ton (NZ$2 each compressor)
    Sell the 1Kg Copper for NZ$7.50Kg ($7.50 each compressor)
    Sell the light gauge for NZ$70/ton (dunno how much in each compressor, I will just ignore it).

    Each 9 Inch grinder disc costs NZ$7 , it will do 14 compressors, thats 50cents a compressor.

    So, buy for NZ$1, scrap it, sell it for NZ$9.70 minus the disc @ 50cents

    Keep NZ$8.20 as profit
