Re: [TCML] climbing sparks

Thanks for the hints, and what I'm concerned mostly about is the possible 
welding together of two adjacent turns.
I know that a shorted turn affects the Q, and also the resonance, but to 
what degree.  Maybe I'll just use some mild abrasive to remove the carbon 
and re-seal with urethane.  I think I caused the problem myself because I 
ran the coil without a breakout point.  It really looked great though with 
all the long purple streamers!  Thanks again guys.  Dan/ag2z
