RE: [TCML] Pig based coil design.

["Jim Mora" <wavetuner@xxxxxxxxx>]

Hi Gary,

Free PVC is good, your advice on spark gaps is less desirable. I had a blown
gap on my 8" coil that worked very well. I would think things would tend to
melt down @ 12KW with your gap style. Can anyone second this claim?

Thanks,
Jim Mora

Ok.... what exactly are you looking for.  Plans you can copy?

Here is a link to my 10" coil.  Secondary is 950 turns of #18 enamel coated
copper wire close wound on a 10" diameter PVC pipe.  Secondary coil has 3
coats of polyurthane.  Primary coil flat would 1/4" copper tubing 1/2"
spacing with strike rail.  Variable speed vacuum fan RQ spark gap.
Capacitor is .035 uf 40K volts. The coil produces 12 foot arcs on about 12KW
at 14,000. volts.  The variac tunes the spark gap to the exact speed to get
maximum output.  I can dial in about 1 extra ft of output arc length with
the spark gap vacuum fan speed control.

My suggestion is forget the rotary it is just a fancy over priced toy. Build
a variable speed vacuum fan spark gap.

I have a 15" diameter PVC pipe you can have it FREE if you come and get it
in Murfreesboro TN 37129.  I have a truck load of other diameter PVC pipe
6", 8" and 10" it is all free to anyone that will come and get it.
