There's an old trick that makes sizing wire easy. Take a pencil, and either
measure a half inch or a whole inch on it. Use a knife to make thin nicks on
the pencil to mark the ends of the inch or half inch.
Now just tightly wind your wire between the two marks. Count the turns. If you
used the inch, you now know the turns per inch. If you used the half inch,
multiply by 2 to get the turns per inch. Now you can look up the tpi in any
wire table. It's always there in the ARRL Handbook.
