Well after I made this vawt and saw the results I said, it is time to go bigger so I started constructing the 48" tall by 32" diameter and finished it up a couple of minutes ago. So I decided that since the existing vawt does not spin fast enough that I should take it down and to my surprise there was a nut on the threaded rod that got loose and got jammed in between the metal base of the pole and it was stalling the damn thing, when I noticed this I got made and I just simply put it on the roof and it started spinng with ease.
And this is the bigger one which is waitng for the ball bearing and the 3/4" shaft pole.
