Plans: 1. Drill holes for attaching the wing fabric to the ribs. Status: Complete. I drilled holes to receive the screws that attach the fabric to the ribs. Then I changed my mind and decided to use rivets to attach the fabric. So I re-drilled all the holes larger for the rivets. I decided that the wing fabric is under great stress and felt that the screws would not hold as well as fabric rivets. The rivets will look better as well since they have a lower profile.
