Agreed, it'd be hard to hook up to a wheel hub. I suggested the headset, where the front fork and handlebars meet the frame. You could just hack the whole head tube off an old frame for something quick. Turned upside down it'll support plenty of weight and keep things nice and straight. One possible downside it that it's not really meant for continuous rotation, so friction might be a little high.

Sounds like you're well on your way, though.

One comment based on a sketch from a much earlier post - you'll probably need to support the tops of the blades as well, or make sure the material you use is plenty stiff. You may be well ahead of me on that, and just omitted it from the sketch for simplicity.
