Build your own Savonius VAWT (Vertical Axis Wind Turbine)

Step 3 Add the VAWT blades

Cut both buckets in half so you have 4 blades. It pays to have the dog check your work ;)

I used an electric saw and just held it there while gravity did all the work. You could use a handsaw easily.

Then use a holesaw to make a hole in the top of each half, so it will fit over the top of the broom handle sticking out of the top of the shaft.

Please be careful and take the time out to think at each stage - the author accepts no responsibility for sloppy planning!
