Hi Richard,

>The 4 turn coil starts at gap 5 of the 14 turn coil and finishes at gap =
9
>making it symmetrical about the 14 turn coil. T5 is actually 16 turns
>rather than 14. Do I need to wind the 4 turn coil starting at gap 7 so
>it is symmetrical?

That's how I did it, and it works well.  That also matches some of the
photo galleries.

The number of passes through the hole is the number of turns.
So, gap 5, 6, 7, 8, 9 is 5 turns?  Remember to only do 4 turns.
