This jig is a very functional replica of a very rare original. Made from high strength urethane plastic tooling resin. This plastic has a shore harness of 70D, with a tensile strength of 3000psi. This is a close comparison to virgin nylon. The jig is tough, durable and paintable. They will resist moisture and mild solvents.
This is a tool for producing a 2 or 3 dimensional metal wire dual helix. This will create a symmetrical dual coil for all types of artwork but mostly coil craft. This jig is produced from a custom mold and is not machined. It will incorporate some divots with possible pot marks from bubbles. My master is not perfect and the duplication will be the same. Any artifacts in the tool will not hinder the functionality. Again, this is a clone from my rare master.

This double helix jig will have a stainless steel headless screw at the top for the starting articulation of the double coil. This screw will only support a gap of insertion no larger than 0.030 width wire. 21 American wire gauge (AWG) will be 0.0285 the maximum allowed without help from your fingers. This screw is in very tight but it is possible to adjust it if need be.

Double Helix Jig:
Weight; 2.25oz, or 35grams. Height;2.375 inches +/-0.25. Width; 1.25 inches. Coils; 5 per helix
MAX wire size 22 AWG

The coils in the picture are for demonstration purposes, and will NOT be included in this SALE. This is what the jig will create.

It is possible to produce double helix coils from larger diameter wire by holding the center with your finger while coiling.

The double helix jig coils in the picture are 22 and 24 AWG copper, copper coated tin, and red magnet wire.
