[Elecraft] Tinning toroid leads

[Stuart Rohre]

The video on tinning toroid leads, does point out the ease of doing it by 
first scraping even a single bare copper spot on the lead, and then starting 
the application of iron heat and solder wire there.

I had not seen this before.  He used an Xacto knife blade and one swipe to 
start the spot.  Keeping the blade on a slight slant and scraping away from 
you should preclude any nicking of the wire.
