Hello again Phil,
You mentioned the problem with getting good wood, and I just laminated some 3/4 X 5-1/2 up, this evening !!
I used some clear fir that has been sitting in my garage for about two years, so it should be nice and dry -- total thickness is 2-1/4"..
I noted many guys have been laminating, side by side, in strips, but the best stiffness, is by stacking one on top of the other as aircraft propellers are made !!
I would suggest getting some mahogany, in 1/2 or 3/4" boards and lam them together, with epoxy glue..
Mahogany is a lot like fir, to work with -- but is usually very clear -- i just used the fir, cause I had it !! Also, the last time I bought mahogany, it was cheeper than clear fir...
I will be doing the rough cutting on my band saw, including the twist, and final cutting with a spoke shave and wood rasp -- if it all works well -- it will be on the board, with pictures ...
By the way, laminating also, keeps the wood from warping -- but it must be fairly dry -- The mahogany is normally kiln dried -- again, a big help !!
Nice to see someone experimenting with vortex generators -- keep at it and have fun !! Bill H....

Thanks for the info Bill H and Rotornuts. I'll probably use plywood and about 6 layers of fiberglass on my next set of blades because I have it. Afterwards, the kiln dried wood looks like a very good option.
