Re: [TCML] Secondary winding jig

I personally would want it turning about 4 times as slow as that - but I'm old. The speed you can cope with is primarily dictated by the AWG your using. It's very easy to get a crossed turn on smaller sizes. You then tend to over compensate and you will find your leaving too much space in between windings. Hold the finished secondary up to the light and you will then see the gaps if your using clear tube.
Using a lathe is a good way on a big coil, as you can set the saddle feed up so that it will wind it on automatically and give a nice packed winding.

You also need the motor capable of being left to run unattended for some 8 to 12 hours while the varnish or epoxy dries afterwards

  Subject: [TCML] Secondary winding jig

  Here's my attempt at a secondary winding Jig. <http://yfrog.com/n6coilwinderz>  I'm hoping to be able to wind up to an 8" form on this.  The PVC on there now is 4" x 24".

  The motor is an Oriental Induction motor I got at a surplus store, and as such it's not speed adjustable.  Though the torque is quite high - which could be a downside if I wind up breaking wire - I'm hoping that by only loosely afixing the PVC core to the rotating shaft (with masking tape) the tape will give free before the wire breaks.  The gray PVC endcaps have been turned on my lathe and fit pretty snugly, though they will slip.  Hoping that will act as a "clutch".

  Never did this before, so this is a Version 1.0.
