My first decent Tesla coil

Well here i am doing the good old electricity stuff again :)

Specs are as follows:

4.3inch Secondary, 18.3 inch winding height, around 800 hundred-ish turns, 24/23 guage wire
Primary is 14 turns of 1/4 inch Aluminium power line, tapped at around turn 6
Transformers are 6 microwave oven transformers, configured to output +-4kv @ 2000w
Toroid is 125mm ducting at 21 inches diameter, i put paper mache over the whole of the ducting to give a smooth surface, then covered with aluminium foil tape.
ASRSG: a 11,000rpm angle grinder with a bakelite disc with 4 brass electrodes, bps is around 733
Capacitors: Surplus Russian military, bought off ebay, get's warm very fast, rating at 32,000v at 35 nf

Max spark length is about 29 inches, but that is pretty good with sub-standard building.
Any comments, suggestions welcome :)
