Re: Pre-flight check......

Hey Glen....
your system "looks" good didnt pay attention to the wiring but I did notice one issue that over time may give you problems...
your safety gap ( all 3 mounts)... is mounted directly to the wood base. Even tho wood is "insulative" to a degree, at 12KV it isnt so insulative... with enuf humidity, wood becomes conductive and you could end up with internal arcing thru the grain which will eventually carbonize creating a low resistant path and a loss of power or non working coil.... and maybe even a smoldering base assembly :)~
if you can, find some high density polyethelyne plastic ( white plastic cutting boards are an option) , cut it to size, stack it to 1+" and remount the safety gap making sure there is no metal to wood connections... 

other than that, good looking coil for a first time effort....

I just completed final assembly of my first 4" coil  (well, first
coil period for that matter). I wanted to let some of you take a
quick glance and tell me if there are any obvious violations of the
"TC code of ethics".

Actual secondary winding length is 22 inches on a 25'ish inch form.
NST is a 15/60.  Topload is 4x19 sitting at 25 inches.  15 turns on
the primary (which includes the tap as one turn).  Resonant freq is
around 212khz. I used 300amp battery cable as my hookup wire between
components. Spark gap is set to fire at NST voltage to prevent
resonance in the NST. Waiting on caps....will upgrade the MMC when
they arrive.

I do have one question. Could I get by on a counterpoise instead of
drilling through the garage floor to drive a ground rod? maybe 4'x4'
piece of fencing?


Thanks to everyone who got me to this point.
