Wind turbine with bicycle wheels

Step 2 Add bucket base anchoring pieces

I used wheels from an old off road bike past its used by date. I have recently read that a ratio of radius to height of 6-8 is most efficient so wheels from a BMX would probably be better, but I used what I had. To hold the Savonius bucket base to the bicycle wheel fix two pieces of wood on opposite sides of the wheel to hold them. I made these the same width as my bucket base, but if you were using a full circular base you might want to use four of these. I used 35mm square timber. I actually used 70x35 framing pine which was ripped down the middle.
Drill through the rims and secure the timber to the wheel at each end with 50mm timber screws.
