First Light & Carbon?

["Trent Mullins" <neontrent-at-earthlink-dot-net> (by way of Terry Fritz <twftesla-at-uswest-dot-net>)]

Greetings all,
 
After 3 months and ~450 research and construction hours,
I'm finished.
I achieved 44" streamers from my 15kV 120mA NST, 6"x24", .02 mica cap, RQTCBOR
system.
 
I'd like to extend a very appreciate "Thanks!!" to the Tesla List and it's
many talented members.
 
This is much more than I expected, and luckily, my neighbors love it as well.
 
Now, on to the question:
 
Would carbon rods, the ones used in old theater projection systems, work
well for a spark gap? They are 3/8" inch OD and ~5-6" long.
I ran across a bunch of these and would like to know before I buy them.
 
Many thanks,
 
Trent Mullins
