 Nearly anything will work, Elmer's glue, polyurethene, etc.  The main thing
 is to get it into the problem area.  Your dope of choice should be well
 thinned if to apply to an already assembled core ! !  Maybe apply it in a
 vacuum to get it between laminations.  Commercially xformers are glued
 during assembly.

If you don't plan to take the core apart, use epoxy.  We work on a lot of golf
car chargers (36 volts at 30 amps) and use epoxy to fix the loud ones - which
is caused by loose laminations.   These transformers have very large cores and
would probably be good for re-winding to make a high voltage transformer.  I
would guess you could get 1.5 to 2.0 kva out of one of these.
