Just finished my first blade 1 of 3. I tried holding the blade vertically to a moderate/strong wind, I couldn't feel the blade wanting to turn at all? If i made the blade corretly should I feel a lot of torque at the pivot point? UK DIY Renewables forum currently seeking members and help for the Admin.My Link |

Probably not, so don't worry. There is virtually no torque until it is turning around the hub. Steven T. Fahey |

Yes, don't worry about it. A 2.5meter mill with say TSR of 7, in a 20mph wind, will only give start torque of about 100 grams for a single blade. I doubt you would notice it against trying to hold it steady in the wind... not the kind of force that will rip your arms off.
