>This was something we stressed here at the TCBOR in our first tapes back in
1989!  My first article for TCBA news stressed that the rotary was a vanity
toy for the new Teslaphile.  The rotary gap is not a rosetta stone to long
sparks or even good operation!  It is not even needed until over 5KW, though
it will often appear to improve the performance of a poorly thought out
system under 2KW!

Properly designed static gaps have been used by our group and others in K=.4
coupled magnifiers with no rotary up to 3KW!!

Too many rush to the rotary gap as a solution for early poor design.

Your coil sounds great, good luck with your fuutre efforts.
