    Not much to it is there? Vanes to catch the wind- at an angle so that the wind pushes them in a given direction. An axles without too much friction.

    Try here:
    This si for a large windmill, but you can size it down and use stiff paper (like a manilla folder). It's easy to do, take about an hour.
