Building a Vertical Axis Wind Turbine ( VAWT )

Step 9Making a frame around your turbine

Making a frame around your turbine
First you get two pieces of wood that are exactly the same length.
Make sure they are wide enough so you can make a strong structure.
Look for the center of both of them and make a hole the size of the bearing holder for the bottom one and the size of the top bearing for the top one.
I was lucky i had a big drill to do so. If not take your biggest drill bit and drill it out and then cut the rest out with a round axe.
For the bottom one you have to drill the center of the hole trough with a drill one size bigger then the size of the big wire rod that will fit into the bearing. For the bottom one you will have to cut out a little slot so the nipple can fit inside and that you have enough space to put in the grease pump. You can see what it should look like on the pictures.
Take two more straight pieces of wood for the sides. ( I had some plywood so i used that )
Take the bottom piece with the bearing holder inside and put it on a flat surface.
Use one of the side pieces and screw it on there. First drill some holes in the side so the screws will go in better. Make sure its perfectly square. ( 90 degree angle )
Do the same thing for the other side.
Now take your turbine thats completely assembled and lower it into the bottom bearing.
Now you take the top piece and slide the bearing over the big rod. Measure on both sides of the turbine and make sure you measure the same distance, that way your frame will be perfectly square.
The movie shows how well it spins. ( by hand of course )
