They were all identical and were E I lamenations. The I was tack welded to
the E. I ground out the tacks and pulled the winding out. Once I knew hiw
to do it without damaging the linations I cut the other three apart. I used
three cores to wind a ballast for my 10 kva pole transformer.
that's useful, but I'm also looking for charging inductors so they need
to stand-off 10-20 kV. I suppose that I could use multiple bobbins in
series, and immersing it in oil isn't a problem.
Does anyone recall what the inductance of a spool of AWG14 house wire
is? (yes, I know it won't hold off 10kV, I'm just looking for a ROM)

Does anyone have a link to sources for suitable cores (laminated,
presumably) for building a charging inductor, or a surplus source for big
inductors (20+ Henry, 20+ kV)
