Subject: Spark Gaps
Hi Folks ...
I am slowly but surely coming to the conclusion that
the reason rotary spark gaps don't work all that well
for low power coils is that they are mostly not very
good spark gaps.
If a few bolt ends don't work at all well for a static gap,
why should they work any better as a rotary?
Think for instance about a rotary gap made of 1/4 "
tungsten - is this a good gap? - with only two gaps,
one on each end of the rotary piece I don't think so.
How does this differ from two 1/4 " bolts facing each
The only advantage I can see is that any power arc
will be broken eventually.
