How I built the CapDisk for the variable capacitor module. Really happy with the sticker cutting machine saves a lot of work and gives consistent results.
If you want to build I have uploaded here https://www.instructables.com/Generat...
I will do the next video for the dielectric I am using basic tests have shown it will get me up in voltage. I have bought an acrylic gloss from a car parts shop and used a brush to paint on removing bubbles and giving good thick coats.
