Hi.
Very, very cool.
That motor seems strong enough to wind two bobbins at the same time (humbucker feller here

).
Tutorials are a PITA to make, as there's almost no way of knowing what the basic level of knowledge is. If I for example was making any tutorial, the engineering people would most likely to get it, but for the majority it would be just jumble.
That said, I'd love a tutorial about the winder.
Regards
Sam
