MURPHY ! AGAIN ??
Hi all:
My sons and I tried out our 2" x 12" coil again using our
mark-1, mod-1 spark gap based on terry's design. The spacing between the gaps
is now approx. . 0085"/gap. We started out using our solenoid wound primary
and found out that it was arcing to the secondary. At lease something's
arcing. :-)
Back to the 30 degree inverted cone primary. Using 8 gaps (4
plus, and 4 minus) , primary tapped at 3 1/2 turns, we were getting multiple
6" streamers all around the edge of our 2" x 12" toroid. (toroid is now
elevated 4" above secondary) I'm sure I'm doing something wrong, because
everything appears to be going well. :-))
I do have a question for Terry about the proper setting for
the safety on the spark gap. I usually set the safety gap about two gaps
behind my shorting bar. The closer I get to what appears to be resonance,
the more activity I see between the shorting bar and the safety. Should I
move the safety back further, or keep doing what I have been doing?
