Well done, you are right it's not that difficult when you overcome the fear.

I would strongly advise never hand holding any form of wind generator however small.

Vibration is only a tiny issue, the big problem is that you have no reasonable way to stop runaway blades. The immediate instinct is to turn the thing away from the wind. That is the day that you learn about gyroscopic forces and chop your legs or head off depending which way you try to turn it.

Very tempting but please DONT do it.

That's good advice. My Plastic 40 Gallon Drum blades ( http://picasaweb.google.com/jehmobile/Wind/photo?authkey=40RK_KqbAU8#5169085925157103890 ) had some VERY sharp edges. I cut my finger just turning them by hand one time.

And the triangular base ( http://www.jeharper.com/windmill/ ) had sharp screws sticking out all over the place.

YES - I would turn it out of the wind, but it was VERY scary!!!

oh, and those plastic blades spun like crazy. You can make them in literally 20 minutes with a jigsaw or sawzall, so I DO highly recommend them. But they are VERY HEAVY and therefore much more dangerous.
