I am documenting the construction of my first wind turbine. I am not an expert, just learning as I go. I am not building a turbine from scratch, but instead trying to first succeed in mounting one to a tower and wiring it up to power small devices inside my house.

The Power of Wind

I want to document the process so that it would be easier for me to duplicate this a second time, as I would like to construct more than one turbine. Also, if the instructions are of any benefit to others doing a similar construction, I would be happy to know that. Let me know if you have tips to share or would like to show off your own DIY wind turbine.

Buy Wind Turbine

After I raise my first turbine, I would like to attempt building the turbine itself from scratch. But for my introduction and education, I decided to buy a pre-made wind turbine I found on eBay. I found a small turbine from eBay seller blairusa. Butch (the eBay seller) builds turbines and sells them on eBay. The particular turbine I bought is small and according to Butch has the following spec’s:

  • 12V
  • 140 Watts
  • Starts spinning in winds of around 4 MPH
  • Can withstand winds over 40 MPH but not recommended
  • weighs about 22lbs
  • Made of aluminum and steel
  • Propeller diameter: 36 inches
  • Length of generator: 42inches

I paid $305 total (including shipping).

Dig hole

I don’t have the windiest location but want to give this a try anyhow.

I picked a location in my backyard. My primary consideration for picking this spot was that it will be out of view for most of my neighbors. I don’t want to make enemies. The turbine will make a little noise when spinning which might bother my neighbors if I put it right on the property line. Some people, for whatever reason, do not like the way wind turbines look. I haven’t talked with all of my neighbors about it, so to be safe, I’m keeping this one tucked away to eliminate any trouble with the neighbors. Also, the location I chose is fairly close to the house, meaning the wiring will be fairly short, making it easier for me to run wiring to get the power into the house.

The turbine will be mounted to a steel pipe. The pipe will be secured in the ground with concrete and guy wires.

At the target site, I dug a hole 1 ft wide and 2 ft deep.

I used a pick and mattock with a shovel to dig the hole.

I had to get on my hands and knees to dig the last several inches using trowels and the shovel.

Assemble Pole

Now we need a pole to mount the wind turbine onto.  I did some reading online and found a helpful site:  mdpub.com.  That site got me started making a pole out of  steel pipes commonly found at home improvement stores.  Below I’ll show you how I assmembled the pieces.

steel pipe assembly

Above you can see a hinge joint so that the wind turbine can be lowered and raised from the ground whenever maintenance is needed. Most of the pieces for my tower came from my local Sutherlands store.  The tower constructions uses the following steel pipe parts:  elbow, tee, nipple, coupling, and adapter.

Note that the tee above is a bigger diameter than the rest of the pieces, so that the threads are unused on the tee, allowing the tee to function as a hinge joint. Most of the pipe pieces have a diameter of 1 ¼”. The tee above is bigger, though, with a diameter of 1 ½”.

A tee was chosen above to allow the electrical cables to exit from the pipe. Later, you will see how the wires come out of this hole.


Insert the pipe into the hole.

Mix concrete and pour into the hole. Used about (4) 60-pound bags of mix. The mix itself then was about 240 pounds but water was added as well, adding to the weight of the base of this mount.

Dig a second hole and place a stationary pipe in it. The second pipe has an arm that latches onto the first pipe. The arm can be detached at any time. I’m surprised how sturdy this connection is.  The arm can hold the pole up with wind turbine mounted to the top without any guy wires.  However, for safety and extra stability, guy wires are a must.  The guy wire installation is detailed lower down on this page.

Apply Plumber’s Grease

I want to be able to detach the steel pipes at any time for maintenance, re-wiring, or other future modifications. Since the steel pipes are outside and exposed to rain, condensation, and humidity, the pipe threads will rust and fuse the pipes together. Already in the short time I have had them outside, they have already developed rust. I picked up some Plumber’s Grease from Sutherlands.

I used an old toothbrush to apply the grease to all the pipe threads.

I put most of the pieces together, minus the turbine itself, to see how it fit together.

With the setup above, the wind turbine blades will be 16 feet above the ground.

Attach guy wires

When the turbine is up on the pole and the wind starts blowing, we need a way to keep the pole from falling down.  I attached (4) guy wires to secure the pole and prevent it from falling down in high winds.

But how should the guy wires connect to the metal pole?  One site showed how eye bolts could be attached to a pole.  [www.jerryriverguy.com/misc/windy.html]  That encouraged me to try the same.

Another site showed how a hole was drilled into steel to make a tripod.  That gave me an idea of how to go about drilling holes into the wind turbine pole.

The guy wires will connect to the eye bolts which are screwed into the coupling.

VIDEO: Assembling Guy Wires to Wind Turbine Pole

Video above shows how to assemble guy wires for a wind turbine.  I learned most of the details from a PDF:   windenergy.com and from a web page at otherpower.com.

Raise pole


One thing I like about this setup is that the pole is raised and lowered by one person and requires no special equipment.

The next video below shows the typical power output of this little turbine on a windy day. It’s not as nearly impressive as I had hoped, but I was still very excited to see “free” power going into my battery.

Typical Power Output on Windy Day

The wind turbine was advertised to produce up to 140 W. So far I have witnessed a more typical output of around 33 W (about 2.5 A at 13.1 V).  I now see that it is common for wind turbine sellers to overstate the power output of the units they sell.

Add Anemometer to Measure Wind Speed


I wanted to measure the wind speed required to spin the blades and begin producing enough power to push current into my 12V battery. I added an anemometer to the wind turbine pole.

The anemometer is part of a weather station kit, the La Crosse WS-2316U Wireless Weather Station.

Hoping for Wind


  1. Butch Williams says:

    I like your tilt up tower. It all looks great. I hope it does well for you.

    Its me, who built the turbine.

  2. Aditya Parakh says:

    Keep up the Good Efforts ,

    Do Highlight about the details involved in connecting the pole to wind turbine ,
    As everyone may not get the exact same turbine and pole , so do advise on a general tips about how poles and turbines can be attached.

  3. Earl says:

    Aditya, After your post I added a new video above. In the video you can see the wind turbine has its own one-foot black pole sticking out of it. This short section is permanently attached. The black pole then slips inside the slightly larger diameter silver-colored steel pipe. It is simply a slip fit and nothing is bolted down or screwed into place. I am relying on gravity to keep pulling straight down on the turbine. Even in high winds, the turbine makes no attempts to fly up and out of the rest of the pole. It’s just too heavy for that.

  4. elle says:

    hi there, could you email me and let me know what the name is of the pipe that fits into the tpipe on the base of the wind turbine. I need to buy it but not sure what to ask for in store. Also could you tell me the components that fit on the top of the tpipe.

    I really like your design and the ‘hinge’mechanism is a smart addition to allow easy maintenance of the turbine. Good job!

  5. Earl says:

    Hi, I have updated the list of the steel pipe parts to help you know what to ask for. steel pipe parts

  6. Watson says:

    If the turbine is allowed to rotate more than 360 degrees, the cable would get twisted and eventually break. Some stop is needed to prevent this.

    Thanks for changing the CAPTCHA. I hope it’s not too easy.

  7. Earl says:

    The twisting was originally a concern of mine, too. But this wind turbine has been up for over two years with no trouble.

    If you flip a coin 1,000 times, you will get about 50% heads and 50% tails. The probability of getting either side is roughly 50/50. I believe it’s the same for the rotation of the wind turbine. The turbine is probably about as likely to turn clockwise as counter-clockwise. Roughly half of the turbine spins will be clockwise around the pole and the other half of the spins will be counter-clockwise. Because of this, the cable never gets twisted by much. I verify this by looking at the cable coming out the bottom of the pole.

    I do think a stop of some kind would be a good addition for safety and reliability.

    Thanks for testing the CAPTCHA. When I disabled the old CAPTCHA, the spam immediately started flooding in. With this simple script, so far none have gotten through.

  8. Tomas says:

    Did you concider vawt (vertical axis wind turbine) it works in weaker wind because has more active blade surface.

  9. JohnM says:

    Hope your wind genny is working well. I’ve toyed with the idea, but north central Arkansas is not conducive for wind. I’ll stick with solar.

    Are you charging a battery system with the output from your wind genny?

  10. Earl says:

    Solar does seem to be a better choice for areas that get little wind. The strongest wind we get at our location in Arkansas occurs when a storm is rolling through. Remember the year 2014 tornadoes that went through Mayflower and Vilonia?

    Since I installed the wind turbine shown on this page, I came to the realization that the Lord Jesus has authority over the storms, the one who says, Vengeance is mine, I will repay, saith the Lord. [Romans 12:19 KJV] It is hard to generate power during hard stormy wind without the turbine being shredded into pieces, like the trees were shred in Mayflower, as shown in the image above.

    I abandoned my wind turbine project in the past few years, because I woke up to our spiritual reality, which is far more important, and I have been learning what God expects from us to be saved. I learned that God expects us to love one another, even our enemies. [Matthew 5:44 KJV] The world believes the opposite, bringing upon themselves storms, chaos, and hell, because they choose evil instead of good.

    I continue to have a lone solar panel, which has been mostly maintenance free, delivering power to the garage. Peace to you, my friend in Arkansas.
