Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hello,
Hey guy's and gal's I should already know this but I dont on the wind mill does the convex side go towards the wind or the concave side? I believe the only Dumb question is a unasked one.
Thanks Gary

Concave is upwind, convex is downwind.

GOOD QUESTION!

I use "symmetrical-section" blades (no lift), so in my case, it doesn't matter!

Threw that in to show you there is always an alternative design. Each design, by the way, has its own pros and cons.

Hi Mac,

I thought your blades were cut from flat sheet, with rounded edges. This is pretty symetric. I did not think you removed almost half the metal from the flat sheet to make your blades. Did I miss something?
