Hi everyone! Ok, first time posting, sorry in advance if im breaking any rules. Anyway, I am building a tesla coil and I have lots of questions before I spend anymore time and money. If y'all wouldn't mind checking out my specks and telling me If im doing anything wrong I would greatly greatly greatly appreciate it. Secondary: 4" sch 40 PVC (4.5" diameter) 20 inch winding height with ~1200 turns of 26awg. Primary: 15 turns =BC" copper tubing =BC" spacing. Power supply: 2 12kv NSTs @ 30 ma each in parallel =3D 12kv @ 60ma Capcitor bank: sort of complicated I need ( I think ) 18nF so (sorry about the lack of a picture) this is what I think I should do. Each cap is 5000pF, and 3kV. 4 caps in parallel and two caps in series should give me 12kv and 10nF. I need roughly double this so, two of these groups will be set up parallel to each other giving me 20nF at
12kV. In order to double the voltage rating I will put two of these groups in series. This should give me 20nf @ 24kv. I think I have this wrong so please help! Oh yeah, each cap has a 1.3mega OHM 1/2watt resistor across it. Spark gap is 7 X =BE" copper tubing on a section of =BE" HDPE. Two squirrel fans for quenching. I need to design a NST protection circuit. I'm sure ill just copy someone else's. How long can I make the secondary after the end of the windings? Can I have a 9 inch gap between the windings and the toroid? (I hacnt decided on the top toroid yet. Thanks again, i really want to get this thing up and running,.- posted
