Hey,
I built the coil described in the article. The coil itself looks quite
"midevil", and is a beauty to behold. I made the supports for the coil
out of clear plex, which may or may not look better than the wood that
the article calls for. I also tried to build the primairy transformer
that is included in the plans (a disruptor style inductor), but I lost
patience with it after winding fourty layers or so of the secondairy
(which is 150 total layers of 250 turns each of #34 wire), which is a
shame, because I think the inductor would be almost as neat as the coil.
I finally just got a NST to do the job of the primairy. The coil is not
a great performer in my opinion, but i have not had a chance to tinker
with it a whole lot so it may just be way out of tune.
For performance, I would recomend a monopolar coil, but I must admit
that this bipolar sure does look good even just sitting there doing
nothing.
FWIW,
