Dan,

Sounds like a nice cap! What voltage are you planning on running it
after break-in, and are the plates vertical or horizontal? Looking
forward to seeing the pictures!

Safe coilin' to ya!

Bert,
	The plates are Vertical and currently my system runs on a 9 KV
120 Ma neon. After I allow the cap to settle for a week I'll test it with a 5KV
neon. And then, 9KV  testing followed by a gradual break in on my coil
for about a week to get the air out. 

Note: I have sandwiched the stack between two 15"L x 8"W x 1"H peices
of pine. As the air is worked out of the stack, I will tighten down the two
1/4" threaded rods, I'm also using as electrical contacts for the plates.

 I will be running at 14.4 KV when my second 5 KVA 7200 Pri pig arrives
sometime in October. At which time I will be back in the Capacitor building
business. And, of course more ballast will be required.

Picture projection dates sadly, I'll say, third week in October. Unless of
course, I can scare some more spark out of my present bank of commercial
capacitors.

Big Red, HV Capacitors. I burned them up.
