Step 2Modifying the Strut
Most homebrew wind turbines are designed to mechanically turn out of high winds. This is called "furling" and is very important to protect the wind turbine in high winds. Do not underestimate the amount of power in a strong gust of wind, as it can seriously damage a wind machine. To have the turbine turn out of the wind, the generator and blades are mounted off to the side of a yaw bearing. We mounted our generator about 6 inches away from the center. This is overkill for this size generator, but we'll be playing it safe as this will cause the machine to furl earlier.
In addition to mounting the generator at an offset, the tail will be mounted to specification to allow the generator to turn while the tail stays straight.
We removed the spring and the inner cylinder of the Volvo strut with a cutting torch. We also removed the rotor (to be modified later) and the piece of metal behind it. Then, the remaining piece of the strut was cut in half and welded onto the side. We also added a piece of metal to give another place to attach the stator to.
