Note that metal plates need to be thick enough to hold their own weight and shape, as in old style air-gap adjustable capacitors. The plates were about 5 mils thick. Note that high-energy capacitors for arc simulation will use a thick dielectric with metal foil, soaked in a light oil as a coolant and to prevent internal arcing.
