Arc pulling, was Touching/Sitting on your coil

["Paul Mathus" <pmathus-at-learningco-dot-com> (by way of Terry Fritz <twftesla-at-uswest-dot-net>)]

     Interesting.  I have pulled arcs off my coil using a 5' piece of 1" 
     pvc pipe.  I ran a piece of magnet wire from the fence where I ground 
     my coil to the end of the pipe and electrical-taped it on, with about 
     4" sticking out.
     
     This worked fine for pulling arcs off the coil, and there was no 
     tracking in the pipe.  This sounds very similar to what Richard was 
     doing, except for the pipe material.  Perhaps because your coils are 
     more powerful than mine?  Or is ABS more succeptible to tracking? It 
     is black here in the states.  I am running a 12/60 nst coil.

Hi
        I have this happen with a chromed steel electrode ball, stuck on the
end of a 1/2" ABS pipe, with a flying lead from the ball fitting to ground. 
A
thin black line has appeared in the ABS, around 3" long, but growing every 
time I use it for pulling out streamers from my coil. Tiny white sparks 
flicker
along this line, and you can see it getting longer as time goes on. The 
rubber
handle on the end is now only around 8" from this tracking.
                                                Richard Barton.

Keep in mind that the discharge will travel MUCH further along an insulator 
than through free air. We have used a "Jesus Stick" since our first demo 
made from 1/2" UHMW round stock and over 8' long with a telescopic antenna 
mounted to the end to attract streamers. When they connect they will climb 
up the stick to the person holding it. We've never been bit, but it will 
easily get to within 2' of the person holding it. Leave it there for a few 
seconds and it will start to carbon track and turn the insulator into a 
conductor, making it MUCH more dangerous.
