I started out with a winder built from Jason's plans. I left out the automatic traverse because I wanted to hand feed. I finished a new winder made out of a hobby lathe which I am really pleased with. Dead true and spins a lot faster than I need it to.
It's the tail stock that I really wanted in a machine. I made a number of faceplates that clamp the bobbin in between so there is no distortion due to tension. It was really the P-90 bobbins I had trouble with.
