After much experimentation, I have devised a way to wrap 360 winds on a small torrid surface. I have done this by using all 120 pins as a single first wind. Then I use the initial winding

Here is the winding series table for the Vortex coil:

Here is the Yin winding pattern.

Now, using the Yin wire as your guide, wind the Yang wire always to the right of the “guide” wire.
