Subject: Re: [TSSP] racing arc thought
hello all, I have some thoughts in the back of my mind about those thick poly coatings over the windings on most coils, you see, I never saw a acing arc until the very first coil that i coated with many layers of spray polyurethane? Most all my coils are a "moto finish" red, this is because i tended to coat the windings in layer after layer of insulating varnish. I liked the 2kv per mil. of dielectric property and the color is nice too. I did wind a very small coil onto a "creamora" bottle (polystyrene" i believe) This coil would race up down and sideways even with a 530 nst turned low. This was also the first coil that gave me the "extended charge" zap after a run, since i coated it in moto finish, I tend to believe the charge was in the former? I have a "gut" feeling that those thick coats of poly can build a static charge that at the very least, cannot help guard against racing arcs. Just a thought of mine that i'd be interested in hearing other opinions on. Take care, Marc
