Re: Design-and-building a large valve Tesla coil (class C, Armstrong oscillator).
Hey Richard, I feel happy that you can see the fruits of your labour in action!
You really did an amazing job.
I was able to re-use the stock that you put in to the ends to turn the piece - they're back to back at the base, one inverted and partially inside the pipe and the other turned upside down. They're glued together and when cured, I can plug the whole unit into a base and unplug it as I wish, for transport, exhibition (eventually) and storage.
I've permanently attached a thick, strain-relieved ground wire to the base (high RF currents) and a copper corona-guard with the other lead-out wire soldered at the top. You can just about make this out in the photo.
How did you apply the varnish so absolutely immaculately without even the slightest run? I can do this on a flat surface but I would struggle with a tube...
Were you slowly turning the lather at the time?
Anyway, beaut job. Thank you again. Stay tuned and I hope you'll be seeing full power before New Year!
