Default Re: Coil Winder Any Info Would Help (See Pic)

Les.
If so, depending on how quickly the travers is back and forth, it could be for making wave-wound coils. In true 'MFJ' style, ('Made From Junk'), I made one of those little 'Morris-Gingery' hand wave-wound coil winders which uses a cam to determine the width of the traverse. I made several cams for coils of various widths. A few pics are attached.

Pic 1 is an overhead view of the completed winder.
Pic 2 is with 40 turns wound onto a coil.
Pic 3 is with 500 turns on.
Pic 4 is an example of a cam. (Which strictly speaking, should be 'heart-shaped').
Pic 5 is a cam which gives 15mm throw.

As Les says, some more pics of the 'mystery' winder might give a few more clues.
