Step 4Cut out the ribs

Cut out the ribs
You will need to have three ribs to connect the two end pieces of each wing. The length of these ribs will be determined by how tall you want the wings to be. I chose 21" because that's what I thought I could mount on the vertical axis allthread bar.

The ribs should be .5" deep and 1" wide and whatever length you choose (21" in my design).

You will be cutting out .5" x 1" notches in the end pieces where you will dock the ribs. I suggest that you trace the end of the end of one of the ribs on a piece of card paper that you can use as a template for drawing on the end pieces. You could measure the rectangle but by tracing it, you can be sure that the notches will be just large enough.
