Thanks but I did not make the turbine I bought it in kit form from a guy by the name of Conner Coady he made it from stainless steel and the blades are larch I'm very impressed with the design and now want to build a larger one my self 10' or bigger (addiction!! is their a 12 step program for it ) we don't have a very good site for wind so the more we get from low winds the better. I have two more that we will be putting up for other people in the next month or so and will take photos and post them if anyone is interested.
