Power arcing on a rotary(?)
Greetings,
Jon Bazemore, a fellow list subscriber, came up to my house today to see
my coil. One of the things that I thought I would try with him was to
put a static gap in series with my rotary I had the static gap tapped at
two 0.030" gaps, as well as the rotary with about 0.060" on each side,
giving a total of 0.060" (approximately) for the static gap, and 0.120
between the stationary and moving electrodes on the rotary, for a grand
total of 0.180" (approximately).
Normally, the gap fires with a snappy sound and no elongation of the arc
between the moving and stationary electrodes. This time, with the static
gap in series, I got a 2" long stretched out arc around the
circumference. Not surprisingly the spark output diminished drastically.
Any ideas?
One other thing to note -- the series gap wasn't truly in series with the
rotary, it was on the other side of the primary inductor.
