Phenolic discs for whimshurts? Answered
So recently I found a webpage about someone using Phenol for a rotary spark gap for a Tesla, I had never heard of this material and don't know too much about it. For a while now I have wanted to make a whimshurst that is larger than the one I currently have (bought online, a gift from my family) but with my current one i have an issue with the acrylic discs not only not being balanced but also warped causing them to start vibrating on their shaft making it harder to turn the handle. I figure that because every piece of acrylic i have ever worked with has been warped that is would be best to find an alternative. My question is, would it be easier to keep phenol flat and balance or would it be best to stick with acrylic? another thing im curious about is this a material that would even work for this application?
Lastly i would like to say that i did try doing a little research on this and didnt come up with anyone trying it for this purpose, i know that in some cases static can act a little differently than normal high voltage arcs (say, from a microwave oven transformer) which brings me to this question.
P.S. im not sure what category this should go in, if anyone thinks there is a better one let me know and i will change it.
