A BIGGER vawt

Postby charlie_ruizpr on Thu Nov 04, 2010 11:34 pm

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.

Great! That central rod - is it about 8mm? It looks far too thin. Not sure what wind speeds you get there, but say you get 400 watts, that about half a horse power pulling on the blades. Would they stand up to that?

This is the shaft that is on the vawt a about 2 or 3 inches from the ground, still waiting on ball bearings. Center plates will be made as soon as it stops raining.
