Re: [TCML] wooden bobbin

Well, Tesla himself made much or his HV stuff out of wood, wax and the like. 
But in this case I would recommend using a light plastic. Nylon for instance is easily machined, and similar practices that you would use to machine wood, could probably be used to machine nylon.

Subject: [TCML] wooden bobbin 

Hey all, 
Still doing some research on making flyback transformers, I'm toying 
with the idea of making a slotted bobbin to make a series pancake type 
secondary, as it sound infinitely easier to wind, and I plan on making 
several... My question is can I use wood as a bobbin material, it should 
be fairly easy to machine to my shape, and much cheaper than plastic, and I 
figure it can just be soaked in wax or polyurethane or epoxy or something 
to provide protection from the corona of the windings... Probably a bad 
idea, but what do you guys think, using wood in a transformer, royally bad 
idea or no? 

Scott Bogard.
