I was remembering how clunky my first whirligigs used to be, and decided to take a picture of my current experimental creation for you all. It spins silently and much more stably than my older creations did. Probably it is blurry due to its motion, plus this pic was cropped from a larger pic.
This is a long term test -- mostly of the swivel -- as the swivel has been used now for more than one year. You might remember the snowfall that destroyed the sun-weakened older blades by spring of 2016. That was the same swivel plus some grease -- mostly coconut oil.
Besides fewer blades cutting down on the sideways motions of the gig, the clunky older versions sometimes had a center pole plus additional layers of blades. When I add magnets into the mix, the sideways wind resistance will increase again, but hopefully not too much.
I am also considering how to curve the coils so they might still be cut by the magnetic flux lines when the gig goes off center due to sideways motions. But I'm also still toying with the center pole configuration, to have centered magnets rotating . . . .
