Development Of The Blades Starting off with a very basic wind mill just to test the blades. These blades are made from 6 inch diameter PVC pipe, These blades required wind speeds of 15 to 20 MPH to spin. |

I picked up some very lightweight blades at the local fleamarket and built a second windmill to run side by side comparisons of the PVC blades Vs the lightweight blades. The lightweight blades spin very well in winds 5 MPH to 10 MPH. |

I finally came up with a very lightweight blade that holds up to winds 10 to 20 MPH. This blade above is made from aluminum roof flashing

The blades are stiffened by bending the edges onto the back side and then forming a curve onto the front side of the blade. I used a vise mounted broomstick as a form to work the curve into the blades. Time will tell how strong of a wind these blades can withstand. My most current lightweight design is a 16 inch long blade by about 3 inches wide.
