Interesting. Unlike my wife, I think a wind farm in our back pasture would be beautiful, but as long as it is view from the house, she thinks one is all she will tolerate. She wasnt crazy about the first one, but she knew I was set on building one, so we compromised with one.
I built mine out of one 42' piece of 3" pipe, about 1/4" wall thickness, I think they called it 'water pipe'. I guyed mine, and put in a gin pole and a pivot on the 42' tower at the bottom, a plentifully deep and wide concrete base. It works awesome. And really, I think it looks cleaner since there is only one pole sticking up, and from the house and the road, you cannot see the guy wires.
I do enjoy seeing the water pumper style towers, the 4 legged ones with the criss-cross strap metal. I grew up with one that supplied water for the house and the cattle, until we got a submersible, then the mill was just for the cattle.
My design came along well yesterday, and I'm pretty convinced it will hold up very well, I just hope the combination of blade/motors/ratios is a good match. I need to bring the tower down and take off the existing parts off to complete the one I'm working on. Its cold out there and lots of snow, I will probly have to take the tractor out there. Thats OK, we need the moisture.
