I'm a bit of a wally when it comes to transformers and tesla coils I'd just like to run some things across before I start building.
I plan to use this as a HV driver/transformer. Will try and find the highest voltage camera I can, using the small photo cap as storage (will rig up multiple transformers and caps if required) to build up voltage, fire the spark gap and power the primary coil.

Now I feel stupid for asking this, but you have the low wind primary transformer connected only to the high wind secondary transformer only connected by a common (not touching) earth, and the resonance does the work?
The primary windings will probably be inside the secondary to make for a more compact unit.
If any HV guys could correct any mistakes I've made, it would be appreciated.
(seen as we're heading up to Perth this sat, I'll head to somewhere that develops disposables and use the magic word to get a bunch of them.)
