balancing windmill blades Answered
a 5 blade rotor.
making our own replacement blades
a fair bit o' resestance to rotation from the generator, therefore, balancing it on the generator shaft is probably a no=go.
the owner, for whom i'm doing the work suggests balancing 2 blades against one another. But there are 5! not 2 or 4.
maybe we make it a 4 blade...
maybe we make sure each blade is excactly the same weight AND with CG at the same distance from center (sounds cumbersoe to get both mass And cg identical.
