Hello, I've already built a small Tesla coil (static spark gap), but I really like to try something bigger - and I'd be grateful if you check my design, if it's OK. (javatc data are attached).
Power supply - three phase MOT (Y-connection) PSU, 2 parallel at each phase (6 MOTs total), each pair has voltage quadrupler (1uF capacitors). Estimated output voltage without load 10-12kV, est. short-circuit current 0.5A. Each phase independently regulated using triac circuit.

If this means galvanized iron strip, it will be an interesting experiment, since current wisdom has it, that only copper will doo.
Yes, it's galvanized iron strip - the downside is that the iron has approx. 4.5 times greater resistance than copper. On the other hand, the copper is much more expensive. This is still a yet-to-be-decided topic.

With much current going through that primary, which it sounds like it would, the iron would heat up A LOT. You really need to use copper. Copper tubing like used to connect refrigerator ice machines to the water source is pretty cheap. Available at all local hard ware stores too.

for the spark gap, I think that using cheap thick steel electrodes might be in order (I belive using tungstun is a waste of money, with that much power I think the expence for the electrodes will add up fast, as your coil will eat them for breakfast.)
