When we talked about wind turbine, then it’s no doubt that the wind generator blade is the most crucial component. The wind generator blade has a curve and large shape, quite the same with the propeller blades of an airplane, and these sharp blades are the main source to generating electricity. Now if you want to reduce cost in making a wind generator then building your own wind generator blade might be the solution for you, so let’s take a look at how to build your own homemade wind generator blades the easy way and with a minimum investment.

It’s actually quite easy to build your own wind generator blades, some of the parts you need can be found in your own garage, such as wood, metal and also plastic. Woods are counted as a good alternative for the past times traditional wind generators, and plastic is the most recommended material to build your blades. You can choose PVC pipes to build your blades because other materials such as wood can crack and that will adsorb water and ruin everything, so forget about creating your blades using wooden material.

Now you’re gonna need about 5 – 6″ PVC pipe of 4″ long and for wind blades that are 30″ in length, you’re able to build the best of 4″ diameter PVC pipes. To build blades between 30″ and 48″, you might anticipate PVC pipe of diameter of 6″. First, the center line should be drawn down the pipe, as the blades branch from the center line and hence makes more power. The blade had better be made pointed for about 5″ at the root and 2 ¾” at the other end, then cut the blades on the absorbed area.

After that you can smooth en the edges near the cut part to get a good finish and before matching the blades, you also may want to paint the blades with the UV protective paint so it will protect the PVC pipes from getting brittle due to the sunlight exposure. For equalizing the blades, place them on the hub and place the hub on the piece of steel rod with few pillow block support. Spin the blades to mark the bottom blades and trim the bottom one a little more than the others, as balanced blades are better than the unbalanced ones.

Please bear in mind that saving money is not the main reason when you decide to build or purchase your own wind generator, there are some factors you need to consider when building your own wind generator such as your skills, time and also budget. All in all I believe that DIY wind generator can be your most challenging home project and it’s a positive way to make a use of your spare time and backyard, better yet you can help all of us to save the environment.
