Nice Set-up. I am just getting into the Bedini projects now and slowly gathering the information on building one. I came across the Bedini motors while searching for information on building a wind generator.
You can expand on the jig if you want to wind multiple wires together by making something out of plywood. Depending on how many wires, one form made to hold 8 coils at the same time. That way you can make a 8-filar coil. After the first nylon guides, then add another that is extended out with another nylon guide that all of the wires will go through it. Since I still have to make the coil, I will come up with a drawing of what I have in mind. Your simple coil twister just turned on the light bulb.
