The tool I use to wind coils I affectionately named the "Cigamajig". Back when I designed it coil winders were in their infancy and well, they just didn't do that well for winding uniform coils.
I purposed to design a coil winder that used constant tension to impart stress into the wire. "Turn the tool, not the wire"
This tool can be made in just about anyone's garage for about $10. I stick of wood, two grub screws, a button head cap screw, a washer and drill bits or screw sizes of your choice to wind your coil on is all that's needed. Even cheaper if one decides to make a tool just for one coil size.
I'm not trying to sell these, it was designed for DIY'rs to build themselves but here are the Pros and Cons anyway.
PROS
1. Winds wire directly from the spool (no guessing how long to cut your wire for X number of wraps) (less wasteful).
2. Winds coils under tension whether contact or spaced coils (coils wound under tension are much more likely to retain their shape while mounting and dry burning.
3. No pinching of contact coils required if mounted without imparting external forces on coil.
4. Quick change mandrel held by two grub screws and one piece design (no hunting for winder pieces or changing screw locations).
5. Winds perfect coils in less than a minute.
6. The Version 2 in the pics below can wind contact or spaced coils from 1-3mm.
7. Button cap screw holds tag end of wire securely so you don't have to.
CONS
1. Older folks or those with tactile impairments may have trouble offering enough tension to gain full advantage of this tension winder when winding with wire gauges thicker than 26g.
