    Exactly how big is it?  Sounds like a beaty--it should serve you for a
*very* long while.  Don't be surprised if it needs hecka current limiting,
however.  Does it say what type of transformer it is?  Manufacturer?  Date?

    Poo isn't good, is it?  We want the coil to be aesthetically pleasing as
well as the sparks. ; ))  You might be able to find 1/4 inch pipe
caps/connectors and grind off the ends.  (I'm not sure they are even sold in
diameters less than 1/2 inch)  If you can't find "hard" connectors of any sort,
try aluminum tape (found in many hardware stores)  However this doesn't tend to
be a good solution to these kinds of problems, as the adhesive doesn't conduct.
I've run out of ideas--but I'm sure others have more.

    If you have a blower or vacuum cleaner, or even a floor fan, stick it
on the
gap.  It's the easiest mod to your current setup, and the one that will
probably
help the most.  Get those ions outta there.

    23" with the fan.  Add all your 15 60's together, and improve the gap even
more, and expect 50"+.  Stick the 20kva piggy on there and. . . actually don't
stick the 20kva piggy on there.  Just don't.
