Wow--that is some nice work, and I like your rotary gap ideas. I too have
thought of using something other than a disk. It looks like it performs
well, judging from your pictures, which are some of the finest coil
discharge pictures I've seen.
Do you have any idea of how much current limiting your getting with your
off-the-shelf inductance? I wonder if the 0.9 ohms DC resistance in
smoothing things out a bit?

I started this Tesla stuff about 16 months ago and do not feel like an
expert on the topic. There are lots opinions and it can be hard to figure
out what is OK and what is a no no. The gist of most coilers seems to be
that it is OK to run transformers beyond the rating for a short time. It is
usually a heat build-up sort of thing. So why not a spool of wire, I ask
I have not done testing on my ballast to see if there are areas inside that
are getting too hot. The outside never really gets that warm. I have a
fellow coiler on video (Gary Lau, I think) saying that it is "slightly
warm". He also tried to put his fingers inside, but did not report
anything. I'll have to get things set back up and check it out in further
detail for myself..
I have put together a bunch of information about what I am running and video
clips from the tesla event.
Check it out. All feedback welcome.
