New sturdy construction
Here are some pictures of the modified blades and support structure.
Also a pointer to a new video.

Fixed vibrations
I've shortened the distance between where the blades connect to the main shaft. I've also put bolts in to permanently hold the pipes and blades at the correct angles. That seems to have solved the vibrations as high wind speeds. The RPM is also higher at high wind speeds, thus capturing more energy.
As soon as we get our new asphalt roof put on our home, I'll attempt to put the VAWT up on top of the roof where it can get higher average wind velocity. I'm also planning to put some solar panels up there.

better connection
I've made a better connection between the windmill and the generator.
It works much better.
We had some >20 mph winds today and I had to stop the windmill due to vibrations.
I need to figure out some strategy for reducing the vibrations at high wind speed.
That is the fun of this project - there is always something new to improve upon or invent.
