Iggy, I'm not sure you need to de-laminate the iron to remove the
copper. if you just cut through the windings flush with iron on both
sides, then you can use your press to push out the center section.
This video shows what I mean, from about 2 minutes to 2:45. I can't

tell
exactly how your transformers are built but I suspect similar.

But wait, this one is a little better,

See 1 minute 48 seconds to 2 minute 20 seconds.
I don't see any reason to disassemble the iron laminations.


I keep telling him that, Mike. I've disassembled several dozens of those
in my life. Again, not to be scrapped, but to be re-built.

There was a time when labor was cheaper than materials.

The two transformers I have are

1) Big
2) There is no gap between windings and the iron core.

It is hard to get a sawzall blade in to get some travel of the blade
when cutting. Here's a more detailed picture of the 3 phase
transformer.

The copper bars you see sticking out, are 2 inch wide.
