re: CD Windmill Generator

Thank you all for the nice comments! I'm pretty happy with the outcome. I did some research on windmills and wind generators and found that my tail should be about 5 1/2" longer for better directional stability. I'll do better on the one I have planned to generate 220 volts for  home use.

Hi Alex, that indexer on the wood lathe is invaluable in many of the projects I do for equal spacing. I also have some discs that mount on the back of my 4 jaw chuck that will do 5, 10 and 7 equal spaces which I cannot get with the 72 hole wheel.

Hi Bigblackyeti. I checked the output of the coils and neither register much at all on DC voltage. But on AC voltage, one put out  3 volts and the other 13 volts with a fast spin on the bench. The wind spins it faster than I could and I get at least 5 volts on the one for the tail because it lights up the 5 v white LEDs when it is really moving. I have to put a new battery in my laser tachometer so I can measure the speed of the fan where it light up the different groups of LEDs.

Cheers, Jim
