This is digging up a prehistoric thread, but here it goes:
You don't need any special tools to build my gap either with the exception of a drill press. I use set screws because they're almost the same mass on both sides, but you could use threaded rod too. It uses a sewing machine motor and arbor from Grainger. The rest is up to you.

I got some welding rods today, cut them into eight 1.75" bits. not sure how to mount them, maybe set screws? still havn't figured out the whole hear thing.
here is my next problem, I have been here and there and I cant figure out where to but the outer elecrodes, and how many...
I think in the link to the thread above its in the same configuration as the first pic below, and I see 4 electrodes. should I go this way?
here is what I was thinking
EDIT, about the pop, its $1.50 CAN per, (hehe) can. But I like pop, and these caps You drink out of before You use, not like "perfessional" caps.
plus, they dont sell good caps at the 7-11 down the street.

for the design on the top left, you can just use a ring shaped conductor on the rotor instead of that U shaped connection. and move the hot stuff to the front, increase insulation distance.
as for the design on the right, i think TDU has a gap like that.
and the number of electrodes depends on what you wnat to build sync or not, and rpm of the motor, bps....

maybe I shoule set it up so I can change it from the one on the left and the one on the right. the I have a huge range of frequency. plus the variac to controll RPM.
as for tonight, finishing 8 more bottle caps.
BTW spending nearly $30 on pop so far, I dont feel to bad about wasting money, i just have to start making my friends and family drink it too.

Corona beer bottles, large tall clear glass wine bottles will work too. I think if memory serves me well a 700mL wine bottle could be 3-5 nF - I have some 1.5 L clear wine bottles that come in at 10nF each!!!
4 large 1.5L wine bottles - clear glass ones will be almost 40nF worth of capacitance , 1L maybe ~6-7nF guessing - 700mL maybe 3-5nF.
