I agree.  It seems the rotary spark gap would add more complication and I
won't be jumping onto that just yet.  My new copper tube spark gap works
much better and as an added bonus is sooooo much quieter than the two bolt
method.  The two bolts sounded like an arc welded on steroids.  The copper
tubes are pleasantly much quieter.  I think I'm going to build another
copper tube setup but this time go down to credit card thickness or even
just some thick paper instead of pennies.  This way I can split my gap
across even more surface area.

Thanks

Malcolm,

If you are going to rebuild your static gap, I would suggest making 
the copper tubes longer.  I believe you said that you cut them to 
1.5" long.  Three to four inches is better.  Allowing more area for 
the sparks to dance around and provides better cooling.
