Re: [TCML] Multilayered Secondary Coils...operation photos.
Hey Jeff,
I could do with one of those for my coil ;-)

Here's

There are three videos. The power supply here is my "universal" Tesla Coil
tuner.
http://www.electrotherapymuseum.com/2008/TeslaCoilTuner/index.htm
Additional reactance and a variac lowers the voltage across the adjustable
cap from 700 - 1000V.
The videos were shot at first having one of the mains wires attached to the
lowest setting of the reactance coil. The gap was too far to fire except
when the circuit was broken periodically (the self-induction of the break
raised the voltage enough to fire the gap in successive "pows".). As the
reactance was decreased to the next button, current and voltage increased a
bit and the gap was able to fire and thin crackling sparks appeared. As the
current was gradually increased a flaming arc finally formed. The next
tests will be done with a variety of circuits built espescially for this
coil and gap, to operate on both AC and DC currents. Kinraide designed some
very strange transformers to operate his coils. One form has two primary
coils and no secondary coils. The primary coils were identical and in each
leg of the mains, and a break was connected to the opposite leads. This
break would interrupt the current in the primaries like a kicking coil, and
the self-induction was used to charge a cap in parallel to discharge through
the water-cooled gap in series with the Tesla coils.
Another form of transformer he designed was like a Pancake Coil, but wrapped
in iron. The concept looks really interesting. The windings are opposite
that of an NST or MOT, high voltage taken from the inner-most layers of the
coils, with the least resistance...
