Hi Ed,
Where have you been!?! ;-))
Most of the details are in my old post at:

Your four inch arcs are typical for a "novice" attempt at the GMHEICSLR
;-)) Basically your are running it as a transformer or induction coil. I
remove the steel core (which just saturates and eats all the energy) and
run the primary and secondary winding's in a true Tesla coil configuration
with a primary capacitor, spark gap, etc. It makes a BIG difference!!
Probably the heat and wasted energy is killing your standard configuration.
You are putting a few joules into the thing like I do but it is never
making it the them big output arcs. Think of making a Tesla coil out of it
and maybe you will get sparks up to 13.249 inches ;-)))
Cheers,
Terry
