What country are you in, it might be possible for you to do it yourself. In canada you can legally do some electrical work yourself and it might be the same where you live.

It's Finland and here you are only allowed to do minor electrical work, like making an extension cord or stuff like that. No messing with the fuse box!
But damn, those are some impressive arcs
Hmm, I've got some mots and caps, might have to try this some time...

*gasp* this is teh sex! :P But does the caps have to be the same type/ratings or is it fine if theyre just from a MO? 'cause ive got around 7 MOC's but not 2 of the same type/ratings although theyre all 2100v and around 1µF.

My caps are odds and ends, and they've held up fine. MOCs can withstand the voltage with a slight margin, and the resonance action doesn't seem to require fine tuning.

Cool, i might try it someday then :o Got all the stuff but im just abit scared, those arcs looks really crazy O__O ..gonna need one hell of a chicken stick before i even dare puttin the stuff together.

I have 12 of them at the moment. How do you think how many should be the best for this circuit (what capacity)?
I think three parallel caps for each MOT are best for big arcs. With four you may get a bit thicker and marginally longer arcs but the resonance starts to fall away and the MOTs get darn hot.
I would put 3 mots in series (if you have) and use 9 caps in 3x3 configuration... You might need to disconnect the MOTs from their cores and put them under oil to avoid flashovers, I have no idea how well would they stand it (remember the resonant voltage is ~3kV per MOT) and of course you would need a storng breaker (~25A at 230V)
