This is a mostly 3D printed all-mechanical coil winder that I designed to wind some coils needed for a Moog Melodia theremin. It is based in part on the Morris Coilmaster design that can create Universal or Honeycomb winding patterns, but I added the mechanism to provide a transverse movement that creates what is known as a Progressive/Universal winding pattern.

The purpose of this winder is to create high frequency RF inductors with low inter-winding capacitance. It does this by feeding wire in a criss-cross reciprocating manner so that adjacent turns of the coil rarely run parallel to one another.

Note: This is not a build tutorial and the files for the printed parts will not be available. It is intended to give ideas to adapt to your own capabilities and needs.
