Re: [TCML] Q,,question { litz wire }

["resonance" <resonance@xxxxxxxxxxxx>]

When you initially "tune" a Tesla coil you have to move your pri tap along 
the copper tuning to tune it.  With Litz wire this would be impossible 
unless you dipped the Litz wire into a solder pot every 6 inches forming a 
bare spot to allow for the tuning.  In short, a real mess.  A pri with all 
those solder globs would look horrible --- probably work --- but look 
horrible.

Copper tubing presents a much more sane approach.  Like Dave R. said in a 
recent email, you can smelt your own steel and copper to make your own 
transformers, but what's the point?   Unless one has infinite time to waste 
this is an exercise in futility.

Copper tubing works great to build coils with spark lengths of 20 to 30 feet 
so no real gain is necessary by using Litz wire.
