[TCML] Rolling your own toroids

["Stephen J. Hobley" <shobley@xxxxxxxxxx>]

I put together a toroid tonight using some 4" ducting I had laying around, and baking pans. 

I taped the pieces together using the aluminum tape usually used to seal up ducting. I have a question, surely the adhesive in the tape is an insulator, so if I were to wrap the toroid in this tape it would not be continuous, but isolated areas of conduction. 

Is this a problem? Or at high freq/voltage this kind of effect is minimal?

I was thinking about wrapping the whole assembly in heavy duty foil, but again any kind of adhesive used to anchor it could create an insulation effect.

I wondered what the 'correct' approach was?

Steve
