Thank You... I'm headin downstairs to cut the five per your suggestion...This is sooooooo... frustrating! When I loosen the allen screw, it spins much better with less resistence(Just freewheeling on the shaft) I guess this is a good way to balance these also...Though I dont know what kind of weights to use on the hub or the blades for that matter!
I suppose I will have to redrill the hub now for for a five blade configuration.. Do you know what degree i would use for the 3" cut? The last ones I cut two 150 degree sections with a 60 degree leftover. Then I drew a line for the tip at 1.5inches on both pieces of the 150 degree sections which made 4 blades. Would I use the same setup?Or.. do I cut the 6inch into four 90 degree pieces?
Any help is appreciated.

Maybe make the blades about 2" wide at the hub where it screws down. It is up to you how well you sand the edges down. If you don't make the "Magnetic Decogger" you might want to make the blades 3.25" at the widest point instead of 3".
Thats a good idea about balancing them on the shaft with a little oil. It is easiest to have a postal weight scale to weigh each blade as you make them, to get them all exactly the same weight. 5 blades should be even easier to balance. If they are off balance, I just tape a 3/16" little bolt/nut and washers to the blade up near the hub to which ever blade is off, and when It balances, I then drill thru the pvc blade and bolt the # of washers in that location.
I don't know where you live, but summer is not so good for smaller mills around here. The winter is quite good though. Where I am at in Ohio, my solar panels probably do on average TEN times more daily watt hours than my 6 foot mill in the summer time-- BUT my 6 foot mill probably does TEN times more average Watthours than my solar panels in the winter months! It completely reverses. In the spring and fall they seem to be about equal.
You might think about getting solar panels ASAP. (or a 10 foot hawt 40 ft in the air! ha)

Maybe you are not understanding how I made the first set.............http://www.thekevdog.com/projects/wind_generator/ This is the part I need to know!!
Thank You SO Much..
Sorry, my Geometry is not so good. That link goes to his front page but it keeps going blank for me?? I just do it the simple "Caveman" way. Maybe someone else will understand the angles and comment.
If all else fails, it would make a nice Ped generator I'm sure for excersise and 30-40 Watthours. (Thats what I am making right now) [ Parent ]
