V8 Vawt,savonius,vertical Axis,windturbine,ametek)

http://www.vawt.ca After making the V10 I realized that off the shelf, cheap dc Motor requires alot of RPM, I do not want to gear something made of so light material that it does not have the mass to sustain the rotation, so I decided to design and build one that has more RPM yet has the same Blade area and that is when I decided to build the V8.
V8 is made from the follwing:

-8 x 3"x10' PVC pipe cut to shape as in rendering($9.89 each)(79.12 total)(vanes)
-2 x 2"X1" permanent caps (sewer pipes aisle)($1.99 each)(brackets)
-1 6" bike axle from an old bike (free or few $)(top axle)
-1 5" long male/female adaptor ($7.99)(bottom connection)
-1 9" hard plastic tricycle wheel (free)(center bracket assembly)
-24 .75"x1/8" screws ($1.99)(screws)
-1 Ametek dc motor ($60.00)(generator)
-frame made from 2x4 ($11.00)(frame)

Total of::: $164.08

Goal is to generate 100 watts at 35km/h

So I hope you guys enjoy this one like the ones before it.

Vanes

The Vanes are made from white 3" PVC cut down the center.

Later, while it was spinning I realized that it was losing air in the middle, so I modded the vanes by adding another section of pvc in the middle. The photos will explain more of what I am saying.

But in future I should have cut the vanes to shape and that will double the cost of the pvc to $75.00.
note: I rendered a drawing for you to see how to cut your vanes (PVC).

I hope I explained it correctly..

And A 1/8" hole is drilled at each side and it is .5" from side and 1" away from bottom.

Again you have to alternate the pvc pipes because of the flange end.

That is it.

Mount Brackets

The mount brackets are 2"x1" permanent cap from hardware store.

I drilled a 1/8" hole around the circumfrance every 2" to give me 8 holes.

I also drilled out 1/2" center hole for the top axle and bottom axle.

Make sure the holes line up, otherwise you will have uneven height for the vanes and that will suck.

Center Bracket Assembly

The center bracket gives you the extra blade area, the firmness and the Cigar shape.

I actually was looking for a 8" one but could not find one fast enough, maybe later, so I used a 9" instead. I simply screwed it in the center of the turbine, again make sure it is in the center other you will get a bad wobble.

Easy sh!t there nothing else to say...lol

Vane Assembly

All together. Like I said, make sure you are in the center of things.

I have included all the pics that will describe the assembly action.

I am not the best teacher but I compensate with my photos.
