Re: dielectric material

I found using 3 to 4 layers of PETE works well for insulating the
secondary from flashover. I just use 2 or 3liter bottles. I cut the
ends off then slice in half and secure with tape. As far as the
bismuth being a metal I don't think I would like to see a cap soaked
in pepto bismaul anymore. Maybe jello tho :)
