[TCML] tesla coil you-tube videos

Working in the snow was bad (because we could only work for a few
minutes and then run inside to thaw; there is nothing colder than
gelling mineral oil on bare hands!) but it was also good as we had no
trouble with moisture whatsoever, which plagues us all summer.
Unfortunately the coil is currently inoperable, as we finally cooked one
of our last 4 MOTs (they got dirty from sitting out in the weather for a
year, and that caused a short,) but fortunately we just acquired a Pig
from DC, so once we get a ballast, breaker, variac, and a few other
things we should be back up and running, with a much more reliable power
supply. We hope to build an asynchronous gap soon, as our first one did
not run (as you saw; coincidently, that night I joined the TCML. That
rotary would stop turning when power was applied so we could not use it,
turns out dimmer switches make funny speed controls.) It will be neat
to begin volume four of our coils evolution, in a never ending quest for
bigger sparks. Anyway, our longest run time is about 10 min, we did not
count, but it was a long run (we eventually cut power not because we
thought we should, but because we were worried about the neighbors (who
it turns out can barely hear us anyway, so we worry for nothing.)) The
huge toroid gives longer sparks than the neat stove pipe configuration,
if you can get it to break out; both top loads are too heavy. I will
tell the guys "hi from Bart", and thanks again for watching.
