Assembling and welding the turbine kit

Begin by locating the stator backing plate and bearing hub as shown in the picture below…

Next.. Insert the bearing hub in the stator plate center hole. You may need to take some sandpaper

to clean up the hole to get the hub to slip in. It’s a snug fit. Make sure the bearing hub is flush with

the face of the plate before welding. You don’t need to weld all the way around the hub as this is not

a structural area, it only holds the stator in place. Four welds equally spaced about ½ to ¾ inch long

is more than sufficient. Be careful not to burn through into the bearing surface. The picture below

shows how it should look when it’s completed…

Below is a picture of the welded assembly from the back side of the unit. The welds are placed in line

with the stator mounting holes

Once this is completed you can weld the yaw tube bracket in place. This is welded between a pair of

mounting holes on the stator mounting plate so there is easy access to the holes as shown in the

picture below…

Notice that the end of the yaw bracket hangs over the end of the bearing hub about ¼ of an inch.

Once positioned weld the top and bottom of the yaw bracket to the bearing hub. Be careful not to

burn into the bearing surface, especially on the ends or you’ll be grinding the edges to fit the bearing.

Next find the yaw tube and insert it into the yaw bracket hole. Center the tube in the bracket (about

4 inches on top and bottom. The hole is sloppy so we can add a bit of tilt to the turbine. Lift the

bottom side of the tube then tack weld it in place. This will add about a 2-degree tilt to help keep the

bottom of the blade away from the tower. The picture below shows the tube welded in place…

Next you will weld the angle bracket on the yaw tube. You can weld the bracket to the tail angle

mount first or the other way around, it doesn’t really matter. What does matter is the positioning of

the bracket or assembly before welding. Below shows a diagram… it should be welded 45 degrees

off.

The final piece to weld in place is the yaw tube stop washer. Simply weld this to the top of the yaw

tube. Center it and weld in 3 - 1-inch long welds in 3 places around the tube… As shown in the

following picture.

Once all is welded let the assembly cool down. Then take a wire brush and clean the welds and

remove any splatter that may have occurred. After its cooled it can be painted the color of your

choice and the bearings can be installed. When the bearings are installed make sure you tap them in

until they are seated against the inner-protruding surface. If they are not then things could go wrong

when the turbine is in the air flying. The bearings could move around changing the gap of the stator

or even driving the magnet discs into the stator. So seating them is important!

Next step is assembling the rotor and installing the shaft….

Find the shaft, ¼” aluminum spacer, magnet plate spacer and one of the 8 inch discs… as in the

picture below…

Slide the shaft in the bearing hub and install the locking collar on the back of the turbine head and

lock it in place. You should have ¼ to ½ inch of shaft extending beyond the locking collar.. as shown

in the picture below…

Now slide the aluminum spacer down the shaft on the front of the turbine as shown below…

Slide one of the 8-inch discs over the shaft down to the aluminum spacer… as shown below…
