You can make a good secondary winder from an old ice cream freezer motor.
It has more than enough torque to wind a 13" dia form, and probably would do
a 20". You just need a frame and a tailstock to support the other end. I
made the frame from some old Unistrut.
Good luck to the Geek Group. They rock.

Looking forward to seeing the process of rebuilding Gemini.
That reminds me. I need to document the CNC secondary coil winder I am
designing for my tesla coil project (Icarus, which I also need to document
further)
The coil winder has turned into a large project in and of itself. I could
spend hours winding by hand, or spend [at this point, weeks] building a
machine to do it for me. It's designed to be entirely modular. Need to
wind a larger coil? Build a larger base, maybe beef up your stepper motors
and the drivers, and you are golden. It'll also handle turning your coil at
a specific rate while your protective coating is drying to prevent runs.
The idea is you punch in your coil form diameter, diameter/height ratio, and
wire size, and it calculates the rest. Just about got it to the point where
I can click go and have a finished coil wound.
