The Artistic Wire Coiling Gizmo -- who else has one?

[Just Don]

I use a 4-40 machine screw for my T3s coils. It make nice even coils. When you're done wrapping you just lightly hold the coil and turn the screw to remove the coil.

I made a new rod from a wire coat hanger - which mic's out at 2 mm.
