Bud,

In addition to Dave's comments on counting turns, I would add that the 
'secret' to winding tight and nice looking toroids is to 'push' the wire 
through the center rather than trying to pull it (yes, you have to pull 
it for the final short distance), and secondly, form the wire around the 
*outside* of the core with a free finger on each turn - that forming 
will produce nice tight turns - attempting to *pull* a turn tight will 
result in frustration and perhaps a broken wire - while a little bit of 
'finger forming' will work nicely with only a slight final 'tug' on each 
turn.

Also be certain the leads are well stripped - right up to the core and a 
bit onto the core.  You want a visible bit of tinned lead exposed above 
the board when you are all done.

73,
Don W3FPR
