Hi Gary,
 From what I've seen, your planned secondary coil is much larger than what 
is usually necessary. I run a 9000 Volt 120 mA neon on my coil, and the 
secondary is only 6 inches in diameter. But if you have that section of 
pipe available, I think that it should still be okay, but other members of 
the list may know better on that subject. As far as wire sizes go, you 
generally want a coil with about 1000 to 1500 turns on it, with a 4.5 to 
5.5 height/diameter aspect ratio for the wound part. So I would look at a 
wire gauge chart (or the WinTesla program found at: 
<http://hot-streamer-dot-com/rscopper/>http://hot-streamer-dot-com/rscopper/) and 
play around with the various sizes untill you find something that works. 
Hope some of this helps. Good luck, you seem to know more than I did when I 
started so you should do fine. =D

I have done some playing around with coils in my younger days but now want
to build real one. I have available a 12 inch diameter 5 foot long PVC pipe
that I plan to use as the secondary. I have four 9000 volt 30ma neon sign
transformers that give me 120ma in parallel producing about 1000 watts,
presently on a Jacobs ladder. For this size coil what wire would be
recommended and should it be close wound or have some spacing between turns.
I want to make a coil that would be hefty enough to stand an upgrade to a
pole pig from the neons in the future.
I hope this question isn't too elementary for the list.

Thanks
