actually this is my first time trying out a wind turbine, so i have based everything on things i have read here and on other sites, for a newbie i would think its an ok project to start off, and no i won't get put off that easily : )
i will try and improve with time and learn from you guys, i don't need it to power a house i just want it to charge my ups battery because there is a lot of problem of electricity here in Pakistan. Everyday there is no power for 2-4 hours atleast. My Ups gives me 2 hour back-up but i want to extent it by adding this.
Hope i'm clear and you understand what i want to say, its my first time so sorry if i have troubled you guys.
I have bought the motor so i'll have to go with it for now, for blades do you want me to craft wooden blades? 2ft long and 3 blades right. I just want to get the max out of this motor, i live near the sea so wind should not be a problem but its swirling type of wind, no particular angle so i'm worried about that.
Thanks alot again.[ Parent ]
Crafting 3 wood blades, 2 feet long will work.
A taller tower will help the "swirling type of wind". Wind swirls less more meters from the ground. G-[ Parent ]
Never tried crafting wood, will give it a go, what type of wood is used for it and are the blades light or heavy? i read in many places but they do not say what wood they used.

Most woods will be ok. Try to get something straight grained and with no big knots.
Softwoods are easiest to deal with and common pine will be ok if you can avoid big knots, Spruce, cedar, Douglas fir etc are excellent.
For hardwoods, ash is fine but avoid the heavy ones. Avoid things like maple unless you have machine tools to work it.

For wooden blades whats the best angle at which i should carve it to better work in low winds?[ Parent ]
There are various blade calculators that will give you the angles and widths such as Alton's. I am sure Hugh Piggott has a spreadsheet that does the same thing on his site. At http://www.scoraigwind.com/
I'll check and read out that website for making wooden blades which i need as you suggested, the PVC one's i made will have to be kept aside then because not good as you said.
Yes fan blades are manufactured to make wind that is right, but i was just thinking its metal and its angel can be changes, i mean it can be reshaped easily, just a thought i know silly question : )[ Parent ]
