Making a simple Savonius wind turbine
The timber frame idea comes from wind turbine by faroun
Faroun Savonius Wind Turbine
plus other net published constructions I can't remember plus some original bits.
Step 1: Make base and top frames.
These frames to hold the axle bolt and make the whole construction simpler. I used 25mm pipe. Add an angle iron section across the the centre with a hole drilled at the centre able to take the wheel axle.
Fortunately I have a mate with a welder and is much better at it than me. Thanks Chris
