Or you could use a coat of pour-on epoxy the regular way, slide it off your
pvc (might need some wax paper or something in there to allow seperation)
and then just put a coat on the inside. I believe that Greg Leyh (?) used a
cardboard form wound and covered with epoxy and then blasted out the
cardboard former with high pressure water leaving the windings encased in
epoxy. Also I don't think that having just the windings in poly or whatever
would do much for performance, it would probably just make a fragile
secondary. After all the losses from the pvc aren't all that big to make
much difference in coil performance (maybe 5% max) as compared to the spark
gap or other parts of the system
