360 Point Vortex Coil using only 120 Guide Pins

After a series of experiments I found a way to wind a 360 point coil on a small toroidal surface while using only 120 guide pins.

The method is simple.

The first pass uses all 120 pins as a single winding sequence.
This first wire becomes the guide for the remaining winds.

The second winding follows the same path, placed consistently just to the right of the guide wire. Repeating this process allows three full flows to be placed on the toroid.

This produces a 360 point coil composed of three paths:

Yin flow
Yang flow
Boundary flow

Because the second and third wires follow the first winding, additional guide pins are not required. This approach allows a much higher density of copper to be placed on the surface of the toroid without running into physical spacing limitations.

Yin winding

The first winding establishes the guide pattern.

Yin and Yang windings

After the Yin winding is completed, the Yang wire is wound alongside it. The Yang wire is placed consistently to the right of the Yin guide wire.

Boundary flow

When both windings are present, a third path appears in the pattern. This is sometimes referred to as the boundary flow.

The image below shows the coil after the initial winding has been completed using the 120 guide pins.

This approach makes it possible to build a higher density winding pattern without increasing the number of guide pins on the toroidal core.
