[Elecraft] K2 Toroid Wire Coating

[Don Wilhelm]

Byron, 

The toroids will work just fine with the outer wires not flat against 
the core, but ---
Pulling on the wire is *not* the way to accomplish nice tight toroids.  
The wire will break before it goes flat against the outside of the core.
The way to make nice tight turns is to use a fingertip to press the wire 
against the outside of the core on *each* turn.  No need to pull 
excessively, just dress it up against the core.
