Thanks for offering me to share by experience. I live in Barbados W I, came across the otherpower web site by accident and got stuck to it by the wealth of info put out. After seeing all the experiments from way back in 2003 etc, i thought of trying one myself, an e-mail was sent to "forcefield" enquiring about magnets, and the the first set of 24 1" were obtained from them. Break drum,plywood, wire were obtained locally (i don't recall how many turns went with the coils) but the 1 in mags were not strong enough. 24, 1-2-1/2 ndFeB plus 4 35 amp bridge rec were obtained again from "forcefield", this time i tried to work as closely with " OUR LATEST WAY OF DOING THINGS "
http://www.otherpower.com/turbineplans.html (" building moulds,templates ,winders etc untill i came to the blades,i just could not understand the carving, but thanks to all you fellas who shared info i got a piect here ,there , every where untill i came up with a diagram of carving a 39 in blade
"
http://www.windstuffnow.com/Blade-layout.pdf" after 2 sets of blades were carved, the turbine was ready. I had some old lengths of 2 in pipe which were used to erect the tower, about 45 ft, 12 guy wires and my genny was flying, giving me a good 20 volts in moderate wind but when i tried to charge a battery the blades would slow down and stop. I must say the tower was erected by me alone with a 1 ton hand puller. I read somewhere if the air gap (and i presume the distance between stator and mags)was decreased it will not stall, so down it came, air gap adjusted, up it went, but this time the blades were parallel with the wing i think the tail was not performing correct. In the process of taking it down the anchor of the gin pole came loose when it was about 3/4 way down, needless to say what happened. I next obtained a 14 ft lenght of 2-8 pine cut in 3 pieces and followed the method of carving the blades
http://otherpower.com/bladecarving.html. Blades completed coated with boiled linseed paint etc, up again but no turning ( by heart sank , wife and kids having a ball lol)down it came "again" bit more carving and ballencing on the blades, up, spinning ,light bulbs burning to the fullest, ( wife & kids enjoying
the light making plans for a bar-b-que in the yard under turbine lights
By the way this turbine had a break system, used a bicycle system to squeeze the mag disc, We had fairly strong winds one day last week and i could'nt let all that wind go to waste so i released the brakes and boy did that turbine fly, flew fo much that the tower broke from the 19 ft joint ( now the entire family is sad)
