    Owners fault! This one is for you Tom; I moved the portable test stand to a different area and mounted the mill on it before I installed the sandbags on the base for holding tower down. Went back for the back for bags and oops! I made of three blades for a customer for his porch fans [the wind off a wide marsh creek kept breaking his store bought blades]. I made an extra blade to test as a wind mill that could double as a battery charger in a long power outage and as a fan with dc motor at other times. Works great mounted to his banister rail when used as a windmill... pepa

Pepa;

I am starting to think of them as "Senior Moments" even though I am still [barely] on the under side of sixty! I had a lot going on that day so probably got  in a "horse seeing the barn door after a day of plowing" hurry and cut corners.

I did find the rest of the shards from the prop about 150 yards downwind. Very thin slivers must have rode the wind. I never have found the "Arts Blades" that came off a Zubbly [RIP] conversion 2 years ago in a spectacular failure reinforcing why NOT to use threaded pipe fittings in a yaw setup.

Thanks for sharing.

Tom

Without fools, you could not look intelligent. There is no knowledge without questions.
