Excellent work! I would love to duplicate your efforts, can you provide me with dimensional sizes, etc? This would be a great addition to my 1st Tesla coil.
Thanks! If you send me a private message I can give you the website that I got a lot of the ideas from for this style spark gap. The rotating electrode is a 6 inch long 1/4 inch brass rod. Not the best material for this application, but it's all I had at the time and it seems to do the job. The blue base it is built on is a plastic cutting board. The rest is easily available hardware from ace and home depot.
Do not let the motor spin down while the transformer is on. This will cause dangerous hv spikes that will inevitably kill your transformer at some point. In fact, you should not use a rsg at all without any cap bank to be there to keep it from getting into the transformer.
Well, as the video info says, only the transformer was hooked up to the spark gap. There was no capacitor bank or primary coil hooked up to it. It was only a test. In the final setup, I have filters to protect the transfomers.
Ok well, like I had said, this was only a test. Letting the motor spin down was just something I felt like doing for this test. In the final thing, I don't let the motor spin down. But if it's so bad to do that, then how do you account for people who use asynchronous spark gaps where they change the motor speed while the coil is on?
Well, like i said do not do this "with no capacitor" :P. If you have a capacitor connected it will just 'absorb' the spikes like a decoupling capacitor does to a DC circuit.
Well, there was some interference on the radio when I did this test, but the completed coil doesn't interfere with any of the TVs in my house. I made a Terry Filter to keep RF from getting into the transformers, and I also used line filters wired in reverse to stop any remaining RF from getting into the house wiring. I wanted to avoid having angry neighbors, haha.
With this spark gap the firing of the gap is more controlled than that of a static spark gap. Plus, with the design I did, I can switch between 240bps and 120bps by having all the rods in place, or taking every other rod out.
Wow! This is amazing!

how do you make a terry filter?

Go to classictesla-dot-com and under "Basics All Coilers should know", click "Protect your NST with this circuit"

I know, but even with filters, it could be a bad idea to use without cap bank, especially when spinning down.

Awesome rotary spark gap.

Neighbor's TV must be going just nuts and they have no idea why.

nice neat work. what advantages does this have
over a regular spark gap?
