Hello Richard:
    The closing comment of yours shown above has me wondering if I might 
have mis-understood some of the information on toroid sizing.  I hope you 
might comment on the physical size of the toroid I built, in a system 
where maximizing spark is the goal.  I have a 48" diameter toroid with 6" 
aluminum duct as the outer rim, this being mounted on a 8" diameter by 
28" long coil.  I have a 14,400 VAC 10kva pole pig and one of the .025 CP 
caps.  My question is, in the above comment I see where you suggest 
reducing toroid size to get best spark, while I thought I had read in the 
TCBA News from early this year where a toroid 2-3 times the secondary 
winding length was considered ideal, assuming enough power was available 
in your article(from memory, not a quote).  I'm sitting here simply 
puzzled, wondering if my toroid is too big, or maybe too small!  Any 
comments would be appreciated-Thanks
