Re: wire
Just make sure you get the solid core kind, which has a copper core.
Readily available at shops catering to the racer market. About $1/foot. A
cheaper way to make your own is to use vinyl (e.g. Tygon) tubing over
conventional wire.
Another inexpensive HV wire source is coax with the braid stripped off.
RG-59 Cable TV coax works fine. RG-213 (RG-8) would be even better.
Opinions vary on whether leaving the shield/ground on is good or bad. I
personally leave it on for most HV use, but then, I didn't wire my TC
primary with it either.
Also, you can get "Neon Sign Wire", which has a polyethylene insulation and
a PE jacket, fairly cheap by the foot (around $0.15/ft, at least in bulk).
The key would be to just support the wire away from other conductors and
treat it as if it were bare wire with no insulation... that's the cheapest
approach, and probably the most reliable, as well. 2 inches should be
sufficient clearance.
