How to build the Wind Generator Blades – a Quick Introduction

 Wind generator blades are the necessary part for the working of the wind generator.  These blades are normally arched and big, and they are similar to the airplane’s prop blades, and these blades are the excellent source for producing power.  Making the own wind generator blade is the great way to reduce the cost of making the own wind generator and it also gives some self satisfaction.  This article gives a good explanation on how to make the homemade wind generator blades to save that excess money.

 It is very important to choose the correct products to make the blades as it is directly connected with the efficiency of the wind generator.  Some of the materials that are used to build blades are wood, metal, and plastic.  Woods are considered as the good choice for the yesteryear traditional wind generators, metal are the very easy item to work with, and plastics are the ideal material to make the blades.  It is highly recommended to build the blades with PVC pipes because of so many reasons such as the wood can crack, wood absorbs water, and the crack makes wood to absorb water.  Also, wooden blades are very complicated and highly time consuming.

 For making three wind blades, a person require about 4” or 6” PVC pipe of 4’ long and for wind blades that is 30’’ in length, a person can make use of 4” diameter PVC pipes.  For making blades between 30” and 48”, one may need a PVC pipe of diameter of 6” PVC pipe.  First, middle line should be drawn down the pipe, as the blades branch from the centerline and thus makes more power.  The blade should be sharpen for about 5” at the base and 2 ¾” at the tip, and then cut the blades at the marked line.

 Sand the edges around the cut part to get the fine finish and before balancing the blades, coat the blades with the UV protective paint.  UV protective paint shields the PVC pipes from getting brittle due to the sunlight exposure.  For poising the blades, place them on the hub and place the hub on the piece of steel thin implement with some pillow block bearings.  Spin the blades to find the bottom blades and clean-cut the bottom blade little more than the other blades, as balanced blades are more protective than the unbalanced one.
