[Elecraft] Trouble With Torroids

[redmen1969 at optonline.net]

When I was building my K2, before the 'toroid guy' (or was it the 'torrid guy') came on the scene, Gary, I think it was, mentioned that he had a little solder pot.  So I went out and bought it for only 32 bucks.  Now I still hate winding those buggers, but I have a ball tinning 'em.
