All,

It is often said that one should keep the tank circuit hookups as short 
as possible. However, in a past TC design I noticed the metal parts 
(capacitor housing & spark gap motor) getting hot. I attributed this 
effect to inductive heating due to the close proximity of the parts to 
the primary coil. Now I’m redesigning the coil (This Old Tesla Coil - 
www.ddlabs-dot-com/tesla.html) and wish to separate the flat spiral primary 
from the rest of the tank circuit. What’s a reasonable distance?

Also, I using a 3D rendering program to prototype the physical 
construction of this coil. This will allow me to better communicate with 
the other people involved in this project. I have posted one of the 
renderings on the This Old Tesla Coil web site mentioned above.
