Hi,

I saw your message on the Tesla discussion list.  Here is link with 
an article and some schematics that should answer your questions:

I've been on the lookout for some field mill parts for a while now 
but have never seen any.  I think it would be fascinating to use a 
field mill to monitor cloud charge during thunderstorms.  The link 
above has plans for the mechanical parts, but somehow the idea of cut 
up pie pans spinning several thousand RPM inside a metal trash can 
does not seem ideal.  If your source has any extra parts, or if you 
end up with any you would like to sell, I would certainly be 
interested.

Regards,

Charles Brush
