Flyback powered Tesla Coil?

Hi.

I am trying to build a Tesla Coil, and there are few thins I'd like to know.

First, I built this PWM (made a few modifications, IRF530 MOSFET and 10nF ceramic caps instead) and connected it to a self wound primary of my fuh29A001V flyback, and it works perfectly, sparks and stuff. Can this power my Tesla Coil?

Next, if it can work, how do I calculate capacitance needed for my tank capacitor?
