Kevin,

If you are building new kits and are intimidated by the toroids - or 
just want to reduce the effort and have toroids with well stripped and 
tinned leads, order the toroids from The Toroid Guy.

If you wind your own, the big challenge is not in the winding (but 
remember that a straight wire through the core is one turn, and a full 
wrap around the core is 2 turns), but the challenge is in stripping and 
tinning the leads.  I strongly recommend the 'solder blob' method - use 
an iron with a wide tip and a higher than normal temperature (800 degF).

One of the common problems with K2 construction is poorly stripped and 
tinned toroid leads.
