That baby is the mother of capacitors ...

Beautiful!
Congratulations!

Very good video, thank you very much, what I could not find is how to cut the plates, since there are not always places to cut them.
Very nice looking work and caps, sure like to hear a bit of chatter from you on what you are doing, makes for a more interesting video. W4GSM
Doubles as a hard boiled egg slicer that handles a half dozen eggs at once.
cuts homemade bread as well.
Can't get a feeling for the max and min capacitances. How about stopping the caps at max and min instead of the useless spinning with the capacitance meter trying to keep up?
good night mate, all right? Which machine do you use to cut aluminum sheets? thanks PU5RSL
Excellent product .Congratulations.
I would have rounded up the edges and the corners to stop discharge at the higher voltages.
What does achieving minimum capacity depend on?
Thanks for doing this for us. KW4PW
What was that, 17 to 53pf?
very good
KY8D here with ideas for enhancement. First there's the problem of electrical resistance. All of those physical joins. And aluminum stays shiny because of a micro-thin layer of oxide corrosion (which is basically saphire, and highly resistant). How about maybe using a product called AlumiWeld to join all those sections along one edge (maybe even across the stacked spacers) direcly to a lengh of Cu bar stock (or even Cu pipe)? That separately for the stator and rotor. Electrically and physically then, each would be a single piece. Resistance problem solved. Anyhow, I'm going to try this. Won't be for a few months, though. So thought I'd mention. Secondly, may I suggest laser cutting as an alternative to CNC machining for all of those plates? Cheaper by half. Maybe only a little more than buying a Russian surplus vaccuum variable...but without the bellows fatigue-life shortfall. Just my ideas, for what they're worth.
Ĝan Ŭesli Starling , why don't we use brass materials? God bless

Хорошие кондетсаторы
would have been better with some conversation about what was the spec and such.
that's a gigantic tuning capacitor! how much do something like that cost?

I run into you again...lol I am following a path that I hope will lead me back to where I was a few years ago when Grandpa Don was around. I have to say that I know for a fact that the B+W coils are magick. You may know what I am talking about. I had friends that did research on RF coils and the original research on those types of coils is very enlightening. believe that Don's were hiding a structural secret. One coil was copper and the other was aluminum. These capacitors are great but the ones that I have seen work better are made of PCB blanks. There is a video on them. These will do exactly what you need them to do. I also found out the hard way that we need 50kv/20amp diodes after the full wave center tap. My working builds used coils and diodes as well as capacitors from Grandpa Don and now he is gone so I have to reevaluate the values of everything used. I was privy to so much and I did not even realize it at the time.
Do you know I was thinking of making one myself but it's getting the plates cut put me off. Thanks for the video.
hire a water jet. supply the metal.
Beautiful air capacitors my friend!! Are you still around?
For a loop, all those connections should be welded/soldered.
I want to buy one of them from you. I need at least 10-125pf, 10kv at How can I get in touch with you?
still in business?I got no reply to an email
I need this type of capacitor
Do you offer the kit for sale?
Joe Pfeuffer
Yes I do>
the minimal capacity is big
That's what I thought. You're not going to get very great tuning range
How to calculate Tuning Capacitor?

plexiglas ist no god
Plexiglas is not optimum but true Lexan works well.
Pertinax gives better and more consistent performance. God bless
