Jig Preparation:
The winding jig is used to wind the coil. The Jig and the Jig holder are fastened together using M3 fasteners.
Print 2 Jigs, fix them along their shape, and elevations facing each other.
Attach the 3DP Jig Holder on one of the faces. I recommend marking this face, and you should use the same convention when winding all the coils., and the winding direction should match.
Fasten everything togehter
There is a small hole in the jig through which you can slot the wire, to keep it in place while winding. Put the 30 AWG wire into this from the inside of the jig, coming out.
Attach kapton tape in the 3 slots . Once the coiling is done, the kapton will be folded onto the finished coil to hold its shape.
Coil Preparation:
The jig is mounted on a power screw driver/drilling machine using a HEX bit. There is a notch on the jig to indicate when the maximum number of coils are reached.
Try and maintain a constant level of tension on the coils to get a roughly same number of coils. 6 coils will need to me made like this.
Use kapton tape to keep the cool from unwinding. Keep the kapton in place on the inside of the coil, and wind on top of it.
There is a hole on the jig where the start of the coil is placed. As long as you use the same convention for winding, and placing into the coil holder, you should be alright, only the polarity of the DC would change.
To Do: Automate this process with a encoder and counter to be more accurate.
If you have the patience, you can hold the handle and wind by hand, or use a drill/power driver to make this faster. You need 6 coils.
Fold the Kapton tape over the coil to hold it in place. Now work backwards to remove the coil.
