Thanks Nibs. I might be able to move the thickest part back by adjusting my router, but I don't know how I could get any twist while using a table saw to cut the blade. Also, I should be able to round the lower portion of the leading edge some which would make the effective angle of attack lower also.

I read about Bergey wind turbines using "pultruded" fiberglass blades that were the same chord the whole length and had no twist. They claim that they perform well, so I thought I could get away with something like that, only made out of wood (which is cheap and I have lots of) and using power wood working tools (that I already have). Low to no cost, just some time to figure it out and make them up.
