How to build a Windmill
Lets start from the beginning shall we.
Materials & Tools
The basic materials that you will need for your homemade windmill are balsa wood, metal sheeting, metal piping, PVC piping, rotors, strapping and a generator. The tools are your home handy man tools such as electric drill with the extras, saw, hammer and a possibly simple welder.
Minimum Wind Velocity
The minimum wind velocity should be about 7mph and the maximum can be whatever you want but you will need to make sure that in a smaller wind area there are more blades with a thinner diameter and in a higher wind area there are less blades with a thinker diameter.
Windmill Tower
The tower is generally made out of metal piping so that you can place your wiring through the middle of it. The tower should have a pivot connection to the shaft to allow it to rotate at least 270 degrees.
Shaft & Tail
The shaft is a long slab of wood that has the rotor and generator on one side and the tail of the windmill on the other. The shaft should generally be a few feet long and the tail can be made out of sheet metal or wood also.
Rotor and Generator
The rotor is what the blades are attached to and this is one of the most important parts, I suggest using a large pulley wheel. Beneath the rotor is another pulley wheel that is attached to the generator and this is generally smaller to increase energy efficiency. The pulleys are linked by a strap that is generally made out of rubber.
Blades
The blades can be made from PVC or balsa wood and should be attached to the rotor at a bit of an angle. They should also have a slight twist to them just like the wings of a plane, this increases the efficiency enormously.
