Re: Winding technique

Original poster: "claudio masetto" <claudmas@xxxxxxxxxxxxxxx>

The clamp is clamping the winding wire and therefore tension can maintained while winding resulting in a nice tight coil. This can be a simple peg arrangement with a couple of pieces of felt or it can be made adjustable so that tension can be adjusted to suit the gauge of wire. It is mounted on an arm which is in turn mounted on a lead screw which guides the wire along the length of the coil.
Another thing I have noticed is that a lot of coilers who wind their coils place the spool with the winding wire horizontal to the secondary they are winding supported with some sort of bar. This is not necessary. The spool can be sat upright and the wire will just unwind beautifully. No problems with an overunning spool.

"One interesting trick large commercial xmfr winders use is to route the
enameled magnet wire through a simple piece of cardboard in a "V"
shape.  A
small lightweight clamp allows different tension on the cardboard V
depending on the gauge of wire being wound.  It was amazingly simple but
they used this technique on over 20 winders all hard at work winding

The magnet wire is located on a simple dowel type arrangement and is
down near the floor.  The V cardboard is up on a metal stand at a level
with the xmfr being wound.  The magnet wire makes a approx 70 degree
bend at
the cardboard V.

The engineer told me they have used this technique for over 40 years!
Simple but effective.

We use a similar arrangement with our lathe.

I think I picture the setup EXCEPT I can't figure where the clamp fits
in; what is it clamping?  Please explain more because this sounds very
