Hey guys,

I dug up my old 6" coil that I made when I was 14 - 8 years ago. I 
hooked up my 11kV pole pig and used only 0.02uF of capacitance (I need 
over 10x that to draw the full 10kVA). I took a few photos and posted 
them to my site (below). Longest spark is nearly 60". Not bad for only 
a kW or so. Also, the primary is steel, yup steel, strip used for 
joining wood rafters in house construction. It's very low Q. And it 
shows. The primary gets too hot to touch after only a minute or so of 
continuous use! I used the strap because it was cheaper and easier to 
bend for a 14 year old. The best pics are on the second page.

Cheers,
