Ed,
   I was able to remove the center winding by cutting off the connecter lugs
and simply pulling the wire out with a pair of needle nose pliers.  It wasn't
easy with the first turn, but was easier after that.  The hardest part was
breaking the glue, but it is not that difficult.

too much current when shorted.  Why not put a 100K or so, power resistor
across the secondary and let it have a load and reflected impedance and then
measure the current draw?   I was wondering why those trying to use MOT's for
inductive ballast  for a pig don't do this rather than shorting the secondary.
I could be missing something here.
