Re: [TCML] Primary to Strikerail arc.

["Vinnie" <teslatech@xxxxxxxxxxx>]

Thanks for the info.

I ended up removing a few turns from my primary and raised the strike rail. 
Everything is working perfectly now.
I have a very very short run posted on you tube right now. It's not very 
spectacular and it's very low quality. It's
also before I removed the extra primary turns so you can catch a couple of 
primary arcs.
My buddy had this little hand held usb video cam. If anyone cares to see. 
I'm running it with a breakout point.
My buddy decided to use an r-rated exclamation to describe it so if your 
sensitive to that sort of language
beware.

Also have a question. I have seen people draw arcs off their coils with 
some sort of grounded pole. If one were
to make something like this what are the requirements? I have a helecoptor 
static discharge pole I got off of ebay
a while back that I think could be suitable for something like this but I am 
not sure. Is anyone out their familure with
that sort of device?
