Doh!  You've given away my plans now!  Changing the 4kVA coil for
Maggy use might require a lot of changes (mostly to the primary) but
this is where my mind was going.  And if things sort of scale up from
the smaller level, i can hopfully have my 3rd coil sitting 4-5' off
the ground, plus the extra 4.5' of coil height, should allow for some
much longer sparks as i would gain a good 2-2.5' of ground clearance!

Actually, while it didnt ever come close to striking the transmission
line, i need to do a test (while im on this smaller scale, and IGBTs
arent so $$$ here) where the 3rd coil does arc to the transmission
line and short itself out.  I know that 1) the primary current WILL
soar, but this is why i have an over current limiter ;-).  But, 2)
will this put additional stress on my secondary to primary insulation?
 An arc over between the 2 coils wouldnt be pleasant.. and would
really ruin the one thing i was after, and that was to keep the sparks
away from the primary!

Its time to start reading up on magnifiers.  Anyone know of any nice
sites?  I just want to get an idea of what works and what might not.
