Chuck - wish I could see this baby run! Sounds like it should be a very serious spark maker.
Hope you can post some good pics over the next couple months.

Hello All:
I've been pretty quite lately, mostly because my spare time has been pretty
well taken up with my latest coil project that is "almost" ready to test. I
figure I will be setting it up the weekend of 8/15/98 and putting power to
it now that it is basically complete. I thought it might be of interest to
all to see what my wife has put up with for the last 6-8 months as I've put
this together. Listed below are the general specifications:
Secondary: 23" O.D. by 100" HDPE form, wound on 85 " with #12 magnet wire
(Space wound)
Toroid: 15" x 78" made from aluminum accordion style heating duct and foil
covered insulation sheet.
System Height: 13'
Resonant Frequency: 58 kHz
Primary Cap: .22 mfd -at- 40 Kv
Primary Inductance: 5/8" diameter copper refrigeration tube, 6 turns, 27"
I.D., about 50" O.D.
Gap System: One Rotary with all tungsten electrodes on G-10 disc in series
with an eight gap vacuum gap. Total of 10 gaps each set at .025"
Power Supply: 10 Kva Pole transformer, 14,400 VAC, two Superior 1256D
powerstats with current balancing transformer. Unit built in an old IBM
AS/400 UPS unit. Internal current limiting inductance wound with #4 square
wire tapped between 1.6 mh -22 mh. Three internal cooling fans. Fully
metered. Total weight, about 440 pounds.
The primary/secondary assembly is presently mounted in a transport cradle
which I need to use to get it in and out of the garage (where cars used to
be). It has to be lifted up to the vertical position and this will take two
of us. I have less than 5 hours of work left now so after not running a
coil all summer, I'm getting pretty anxious to get it out and start the
final tuning. Power consumption will be at the 25 Kw level and if I don't
see sparks over 20' by early September, I'll be probably be working to
resolve some built in fault! If a large cloud of smoke is seen over
Wisconsin, that's my coil #5 !
