Renewable Energy Checklist:
 Build wind
generator
 You might have typed "build wind
generator" in Google and found this site. Here we'll
attempt to take you through some basic tutorials that
will prepare you to "build wind generator", or even
"build a wind generator". For the most part, building
a wind generator is easiest when using wood. Sure, you
can use metal, but by and large wood is easier to work
with.
NOTE: This project involves a lot of woodwork and some
large woodworking machinery. The bulk of this website does
not contain projects requiring such machinery and expertise
in its operation. This one is included only for the people
who really want a challenge.
Task: Build wind generator wooden blades
Types of wood
These blades will be 7 or so feet long, and you can start
with four 8-foot Linden 2 x 6's. You are making 3 blades,
but the fourth piece is used because you will actually need
to cut it into thirds and glue one piece on each of the
three full ones to give a little extra width. This project
can also be completed by glueing two 2 x 4's together. The
wood recommended to use, in the following order:
-
Sitka Spruce - this is usually considered the best,
and is usually found the easiest near the coast.
-
Many people agree that Linden (Basswood) is a
common choice for a turbine blade. It is shown to
be a good breed because it is soft, doesn't shatter
easily, and is easier to find than Sitka Spruce.
(Is wood considered a "breed"? I don't know).
-
Oregon Pine with absolutely no knots in it.
When viewing a blade from the outermost tip and looking
inward toward the root (where it bolts to the hub of the
generator or a flywheel), there is a gradual change in
shape along the entire length. These are referred to as
"stations", with a typical amount being seven.
Note that the left side of this diagram is the leading edge
(the side that first hits the wind), and that one side of
the blade is very simply - flat.
Attaching the Blades to the Hub
The blades are attached to the hub using screws from the
backside. Many people have used car parts here with great
success. You'll want to guarantee that the blades are
all equadistant from one another, as well as exactly the
same length from the hub. If not, they could easily become
unstable, oscillate and shatter when they strike each other
or the tower.
