Or you could wind your own...really no reason to use E laminations you
have a lathe...simply trepann out the coil cavity, leaving a "post" in
the center drop in the coils and screw on a round cover to complete the
flux gap

This is why transformer cores aren't solid iron:
http://en.wikipedia.org/wiki/Transfo...ed_steel_cores
"Early transformer developers soon realized that cores constructed from
solid iron resulted in prohibitive eddy current losses, and their designs
mitigated this effect with cores consisting of bundles of insulated iron
wires."
