Re: [TCML] 55 deg. primary


Nice looking coil, and good performance for a low voltage transformer.

Have you tried running it with a breakout point?

You might consider raising the secondary coil to be even with the bottom of the primary, for better performance. Any turns below the bottom of the secondary are producing a voltage contrary to that produced in the upper half of the secondary, effectively reducing the length of the secondary and lowering the net output voltage.

Doug Johnson here; I finished assembling my small coil, complete on its 8 inch base and made a short video of it in operation. I am using a 6kv-30ma NST to power it. The caps are 2- 102-30kv doorknobs, the secondary is 6.5 inches of 24 awg on a 1.5 inch coil-form. This is my second coil, the first one I had a set of plans for, and this one was designed using Teslamap and asking MANY questions of Bert Hickman, which he showed great patience in answering! {thanks Bert}
Here is the video.  https://youtu.be/mqqd1vPy8Ko
