How I built an electricity producing wind turbine

Step 3 Building the hub

Next I needed a hub to bolt the blades to and attach to the motor. Rummaging around in my workshop, I found a toothed pulley that fit on the motor shaft, but was a little too small in diameter to bolt the blades onto. I also found a scrap disk of Aluminum 5 inches in diameter and 1/4 inch thick that I could bolt the blades onto, but wouldn't attach to the motor shaft. The simple solution of course was to bolt these two pieces together to make the hub. Much drilling, tapping and bolting later, I had a hub.

When i see the picture showing the the aluminum plate, toothed pulley and the blades assembly, it set me thinking "could one not use a similar looking ceiling fan assembly"?

Hi, would this pulley be something like a lathe hub? I imagine the hub could be quite heavy, but maybe that doesn't matter when rotating?
