You have to cut the casing of Fridge compressors in half. I have found that 'just above the base' works best. Using a 9 inch grinder with cutting disc.
You can up end it, grab the footplate and shake the compressor out, its hanging by a electric wire and a Steel metal tube, pop the wire off and cut the tube.
I then afterwards fill up the case with the Iron cores from transformers and motor laminations and tack weld two of them 'end for end' and get 'HMS in size' price for it.
The compressors got some Ali peices, a thin Copper tube and a 'Iron/Aluminium' part too it that are seperate from the HMS casting. 3 Allen headed (hex head) bolts hold the shaft in place.
A bit of work and better when prices were higher. I do it anyway, not selling Steel for another 18 months I guess.
Oh, main point here is that the Fridge Copper windings do not have plastic insulation around them, they are clean and lubricated by oil so they are easy to pull out.
I use one of thesewith a Cast Steel hook, and a hammer, to pick the loop end out after cutting the other ends loops off.
I found it, so it was cheap and perfect for the job.
I might mention that someone could make a jig to hold the motor core and use that tool in some way to pull the Copper loop out, like putting a small thrust bearing on the other ends screw and using a battery drill to tighten up the screw thread part, pulling the Copper out.
But I use use a vise and a hammer (and ear muffs...)
