Bud:
Here's a little tip (I'll leave the poetry to Wayne): The first winding
tends to be the loosest, so wind N + 1 turns and then remove the first
one, ending up with the correct number. But make sure you double check
the number of turns. Being off by "only" 1 turn may not sound bad, but
in many cases it represents a big increase in inductance, possibly over
10%. As others have said, just count the number of times the wire
passes through the center of the toroid.
I've easily wound well over 100 toroids in the past few years and have
never had a problem with winding them. Be especially careful stripping
the wire before soldering it into the circuit. You can search the
archives for various techniques. One thing I do in that regard is
insert the part BEFORE stripping the wire, to check for proper fit.
Then I trim it, leaving maybe 1/8" extra on each lead. Finally I remove
it and concentrate on stripping the wire where I know it's going to be
contacting the solder pad. If you don't trim it first, you'll end up
spending lots of time stripping parts of the wire that will either be
snipped off after soldering or will be nowhere near the solder pad.
73's and good luck,

I am worried about the torroids .... should I be?
