Well it's taken a lot of time drawing in solidworks and mastercam, but today a friend and I cut the first pieces to my new winder. I plan to share pictures as it gets built (which will reveal its design) as I have spent hours taking from this forum and want to give something (no matter how small and insignifigant) back
When finished, the winder will have a fully automatic and adjustable traverse. The traverse speed will be fully adjustable while winding without stoping so that you can alter the turns per layer mid-pickup (1 to 100 TPL on a 1/4 tall bobbin). The traverse is driven by belt/pulley to the bobbin spindle. The winder can be adjusted from 0.01 to approx 0.8" tall coils and will wind up to a 5" wide coil. It is cam driven but not in the traditional sense of a traverse rod pushing against a cam or riding with it. The cam contact point is changable with a lever mid-wind without stopping (This features is there to fill either the center or the outside of the bobbin more should it fill up in one space). Max RPM is about 2000rpm.
Here the first picture of the base of the winder. This plate holds the rotating CAM disk and supports the whole traverse mechanism. Doesnt look like much now, but I'm hoping to have her look really sexy in a few weeks.
The one thing I HAVENT figure out yet is the tensioner system. While I know many people here use it and swear by it, I just cant bring myself to use the the felt-clamp method. I dont want that to come off as a slam, but I think I want to have greater control over the tension with some form of selection. I may have to look at a commercial tensioner. I'm going on an experimentation binge and I want to be able to make repeatable minute adjustments to tension.

Might be a bit tricky on the big bits though. When I built mine, I started with the shaft. Once it was centered and everything would turn smoothly I built around it.
