please help me build my own windmill

[pkmawi]

i come from a a place on the planet where things/stuff don't come easy. i am no scientist or scholar, so consider me dumb but i need to build a windmill since electricity too is not to be expected for more than half the time. what i need is a windmill that can produce 500 watt or more in wind speed of <10 mph for most of the time. i would actually be glad if at all it produces any electricity at the moment.
i want to make my own alternator, the one with the coils and magnets, i have started reading about them but clueless as ever, and the things that come after, since we don't get a readymade one around here, even if i could get one would cost me like almost 100000 rupees, which is like trying to save money by throwing it in fire.
i tried using alternators from trucks but it seems they need high RPM to produce any usefull electricity.
so i need help step by step all the way, and i find i might get help here as i am very much impressed with what i already saw on other posts. in the mean time i will also do my homework to try to understand what is being told to me.... thank you

Well my friend, you are in the right place.  It appears you have access to the internet.  All the information you need is on this website and forum.  To ask for 500 watts most of the time from 10 mph winds is not realistic, but being happy to make any power is very realistic. If you get some really windy days, to see over 1kw for short periods of time is very common.  Make sure you check out all the aticles on www.otherpower.com which is the host site for this forum.  You will need some basic metal working tools and someone that can weld.  The rest is done with basic woodworking tools.  You will need some financial resources becaue you will need to buy magnets, wire, and fiberglass resin to build the stator.  Much of the rest can be salvaged/repurposed from metal scrap.  Blades may look hard, but you could carve a set with a pocket knife if you had to.

I did not know how to do any of this unil I found this forum a few years back and started building mine one stage at a time.  You will learn, and others will look up to you with respect because you can make you own electricity.  Unlike myself, you need your own electricity,  I did it for a hobby and do not use most of the power that I make.

Good luck my frind.  You will find the folks on the site quite helpful.

A very good way to get into Wind Turbines is to obtain Hugh Piggott s book "A wind Turbine Recipe Book" (published in many languages), i understand that you can now download it straight from his site,-- scoraigwind.co.uk.
 
The book gives you straight forward and easy to read information from the electric system, matching & winding the coils, making the blades, and all the metal work including the tower arrangements.

Good luck.

Great suggestions so far and I would add: Don't forget about the tower! Having just made a windmill from a treadmill motor and blades from chunks of cedar and mounting it on a 40' tower, I can say that the tower was the most difficult and expensive part of the job. We just raised the tower for the first time yesterday and it was a little scary.
