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.
