An interesting update; Since I wanted to waste the windings so I could get
to the core, I cut them off on my table saw. I used an old 'disposable'
carbide tipped blade that I never got around to disposing. Cut through the
copper as if it were pine. The cross section of the core looked like a
honeycomb. Even sans the copper the core is still remarkably heavy. Now
I've got the tedious chore of slicing the layers apart with a single edge
razor blade. Not especially difficult but there's so dog-gone many of them.

Hi Daniel

I would be concerned about stripping the coating on the laminations that
protects them from eddy currents. I have never had any trouble getting
apart
the laminations with a butter knife once a few of them have been removed.
Of
course it might be very difficult to get out the first few laminations, and
the extraction might even destroy them.
