Re: Strange shock (fwd)

Hi all,

I've been observing all of these different comments regarding the obvious
electrostatic phenomena of the sec. coil surface and there is really little
that I can add. I have indeed experienced this effect myself in the past a
few times and it does seem like, to the best of my knowledge, that it al-
ways involved plastic PVC pipe as the secondary form material. With my
very limited formal education in physics, I will not even venture to give any
theoretical explanation for this efffect. I do know that with my large "Med-
usa" Tesla system, which has a 12" dia. concrete from, cardboard tube as
the secondary from, I do not notice this effect, but don't ask me for a logi-
cal explanation! IMHO, I don't think anyone really knows for sure the rea-
son for this, but most ot us coilers, w/ more than a few weeks experience,
certainly know that this "strange shock" phenomena DOES indeed exist
and also know that it is NOT in our immagination!

Take care, 
David Rieben
