If I keep them touching nothing happens...

I( 've ? ) finally got the pictures online, so take a look if you'd like to help.
They're quite big, but I always say: the bigger the better :roll: :wink:

The middle screw is the third wire, the ones on the sides are + and -.

Beautiful setup, too bad it doesn't work. I think a possible problem could be that the wires + screws and bolts could mean that the voltage goes too low to make a spark.

Do you mean that there's too much distance ( not as in between the screws, but as in the length of the wiring ) ? I get quite a spark if I tap it with a screwdriver though.

If you were to wire the capacitors thru a ignition coil from a car would that not increase the output?
