Building A High Voltage, Air Variable, Plate Capacitor
Not having a lot of money, and having seen the TenTec kits for air variable capacitors, I knew they could be built. So, if TenTec could make a kit, I could homebrew them. I started searching the the internet for ideas. At that time, such ideas were scarce, but I stumbled on an article by a German ham and materials engineer, DL5DBM, Anwar von Sroka.

Build Your Own Air Variable Capacitors!
RE: Build Your Own Air Variable Capacitors! Okay, I think I have it solved. When using spacers instead of nuts to hold the rotors, I drilled two tiny holes near the 1/4 inch axle hole of the rotors, and ran a piece of copper wire bent like a long staple through the holes. After the last rotor, I bent the two wire ends together and soldered them.

How to estimate or measure the max voltage of an air variable capacitor
$begingroup$ The breakdown voltage for air gap is dependent on frequency. As the frequency increases (above 30 KHz roughly) the minimum air gap per voltage breakdown gets smaller. I am not sure if the ARRL posts are frequency dependent or not.
