Today I started on the wing rib installation. I began by finding all of the ribs for the right hand wing. I then put the spar on top of two 2x4s that I had screwed to the bench with the forward side up. One by one, I located the ribs and then drilled the pilot holes top and bottom. Next, I marked the centerline on each of the .032 spacers and then drilled the pilot holes in them. Following the .032 spacers were .125 spacers. After drilling all of the pilot holes I turned the spar over and marked the center line for the rivets on the end of each rib. Then I pilot drilled the ribs using the rear spar.
