Bert,

I think the windings may need a thick coating to protect them from 
burning up due to racing sparks.    I usually just put a couple of latex 
water-based
brush-on coatings on the winding.  Whenever I consistently get
racing sparks on my coils, the winding eventually is destroyed
and shorts out, or the wires burn in two.  Maybe the water based
coating causes the trouble, I don't know.  The large bang sizes
I use vs. the thin wire diameter, maybe contribute to failure due to
the thin insulation of the thin wire.

Cheers,
John

Unlike power arcs,
"racing sparks" seem to be of comparatively low energy, and seldom seem
to do permanent damage.
