keep in mind that this one is easier to build than my Savonius.

i kept it very basic.

to build the turbine, you need the following material:
-3 bicycle 29" wheels $5.00
-12 lamminate flooring $20.00 ( .25"x8"x4'.4") <----only for testing.
-Various sizes of screws $7.00
-3" PVC cut in 2 $50.00 or (cardboard tubing for start) <------only for testing
-wood or metal straping for the inside of rims to keep it from twisting apart. $10.00
- mider saw, band saw,...etc "$$alot of money for the tools$$"

THis Turbine is only to present a diffrent idea on how to build one of these turbines
-I have included 2 movies that shows it in cartboard and pvc tubing.

use proper material for builing it permenently.

i got the wheel from garage sale a dollar a wheel.

the size is 29" diamater and 1" thick with 36 spoks
the wheel is 5.5lbs.

i am not sure if i am going to use the gear for the generator so lets not make a special placment for that reason.

so all 3 wheel should be the same size and 45.5" in between them.
the top and bottom wheels you need to remove 2 spoks every other 4 spoks
but the middle you need to remove 4spoks and leave 1 and so on.
that is it for the wheels for now, maybe later i need more work on them to brace 3 wheels together.

make sure you grease or oil them for better result.

very nice to u your idia  i will be make 500watt vartical axis wec  dc genereter pls send me alternet details and drawing

hi there guys, i have made a new wind turbine style and call it The "FAWT Silo" (fixed axis wind turbine Silo) maybe later i can do an instructable on it, but for now you can visit my site at www.wrapwind.com to see how i did it. regards

could you explane how you built the three pase genorator i am trying to make one too nice job. sky

This is great! Congrats! Several questions. How did you figure out the the number of wings, their length, and the size of the leading edge? How did you make the base - secure the bottom wheel? Have you ended up generating power from this? How did you hook it up and to what? Thanks Brad
faroun (author)  watkinsbl5 years ago
the number of wings and sizes was trial and error basses, i used 3 wings, 4, 5 but the best config was 6 baldes for that diameter 24.5" at the beginig i used sheet metal but it was to flex and did not work for me so the material has to be firm and not to flex, you can use 1/8" steel but it will be to havy for the barrings, the aluminum is a better choice but more money. remember that the wing size was trial and error to come up with the size and wieght is key. -the leading edge is the most critical, if you notice at first i used cartboard tubes and they where from 1.5" to 6" and the best size was 3" and the layout is key, i had the best result when the leading adge was 1/3 on one side and 2/3 on the other. i tried bigger diameter but i needed more robust frame to hold it and that caused drag and the size was not excceptable and i wanted it to go up and not wide. i simply bolted the bottom wheel axil to a firm surface ( i later changed the bottom to ply wood screwed to the wheel rim. i did and do get power from it, as low as 5mph, at that speed i may get 25watt, i know it sounds low but look at what i am working with, i am hoping for 250watt at 25mph. i used my custom generator, soon i will be mounting a 38 volts Ametek on it. i hope i am making sense. please share and learn but alwyas give credit where is due.. regards faroun
wow! 25watts @ only 5mph, that seems way above what others have reported, especially given its ground level location. You did 6 wings on the top and 6 on the bottom, right? How did you cut the PVC pipe in half lengthwise ( that seems like a major feat to me). Why an Ametek; they seem pricey?
Thanks for both of your inspiring Instructables!

i have 6wings+6wings+6wings stacked, not 2 times. i used bandsaw to cyt them. accually Ametek seems to be the value for the buck and it will be best balance for my turbine power VS blade area. i konw that my instructables are not the best written but i am doing my best. regards

"i konw that my instructables are not the best written but i am doing my best." are you kidding me! You have tons of pictures and closeups of things and they are not blurry! I see alot of things that should have more angles of shots of a project, but they don't....so keep up the good work! Although I am curious of the brand of pm generator, and did you buy it, or scrap it out of something? If so, what'd you rip it out of or cost if purchased? The 3 phase motor. What does it look like? How did you make it custom and same question for this motor as above. Thanks and keep us updated.
faroun (author)  mred25 years ago
thanks very much for the encouragement. I pulled the pm I am using from a treadmill machine, I went to a junk yard close by and voila, I got it for 10 dollars and he though he got a great deal. Go to my site at vawt.tk and click on the download link, in there you will find a load of how to custom pm generators Regards

I like what you have done! : ) You are getting a meaningful amount of power from very little air movement too. That is very significant. I like the view of the yard too, it makes the VAWT look as much like an aesthetic addition as a resource.
faroun (author)  bhunter7365 years ago
thanks man, i have been building them like crazy, few i have not posted because the output is not so great, I reliZed that the blades away from centre Vawt need geaaring or custom build alternator that is why i am testing with the narrow and tall the blade area is greater and the rpm add the inertia factor to the mix. i hope you are doing good. why dont you start some other VAWT? regards faroun
