Hey D.C.,
This is Hal in Tucson. I finally fired my 4" coil last night for
the first time. It did quite well. I'll have video on my site later today.
I followed your advise and placed my toroid 2.5" above the last
winding. Will raising it as much as 4" change the capacitance of the
toroid or will it change the resonant frequency of the secondary or both?

2.5 to 4 inches measured from bottom of toroid to the last sec
winding works good with small coils. With large toroids above 30
inches dia., more shielding, we usually go 12-14 inches above last sec turn.

I have a question on the normal location of a top load. My new
coil will max out at 13Kv .150ma , secondary is 6.5/8 dia , is
there a standard starting point for the top load? I see pictures
of other coils, some show it several inches above the top of the
secondary winding , others are quite low with the lower part of
the top load below the plane of the upper winding of the secondary.
Any suggestions on a starting point ?
