The cleanliness of the construction must be factored in. Dirty
plates or dielectric don't hold up. Lint, dust, hairs, sanding
grit, towel fibers, etc., that infest a homemade capacitor will
drasticly reduce the voltage rating of the completed product.
I make sure that my capacitors are meticulously clean, to the
point of setting up a temporary "clean room" to assemble them.
If you roll your caps up on a carpet floor, they aren't worth
the effort rolling them.
... If all else fails... Throw another megavolt across it!
