You're talking about inducing the voltage in the coil, then using the neon
bulb as a clamp at 67v.  I suppose that would work.  Only trouble is
having to wrap and unwrap the wire each time, then restart.  I'm not going
to do it live!

I'm wondering if I can fabricate something from say a big clamp.  Like a
battery clamp, or a 'woodworkers' clothespin type clamp, and put two
halves
of a ferrite into the jaws.  Then put a coil on one of the ferrite halves.
Anyway
every try that?
