Step 7Assemble the wing frame

Assemble the wing frame
To assemble each wing you will insert a rib into corresponding notches on top and bottom end pieces. Make sure that the rib does not protrude beyond the top and bottem pieces. They should should be flush.

With a rib in place, pre-drill a single hole through the rib and into the plywood. Screw the rib into place with a 1" wood screw. You could optionally glue these ribs into place but this isn't necessary unless you are building a turbine that you actually intend to use outside to produce electricity.

Attach the other two ribs to form the wing.
