Thanks for the info Gary, that looks a lot like mine except I used 7/8
dia titanium tube. I am setting up a single gap with tungsten rods and a
small fan to try also. Ref the note from Dr. Resonance.
  I do not have a web site to post pictures to at this time.

9 copper tubes 3/4" x 2" long with .030 gaps and a jumper wire for
tuning
the gaps.  Its all mounted inside of a piece of 4" pvc pipe with a 4"
box
fan.
