RE: Wing Repair 101
Next up was to fix the rest of the ribs and wing tip. For the wingtip I cut a small piece of 1/16 sheet to double over the damaged area and attached it using thick CA with a little accelerator. Since the tip rib was missing a good size chunk I cut a rib to replace it.
I used the cardboard template to cut some vertical supports to fix the remainder of the ribs. With the grain of the ribs runs fore/aft providing good longitudinal support I decided to add the supports running vertical to aid in compression strength. I measured back from the spar for the correct location of the braces and then drew their location on each side of each rib. Thick CA and clamps where used until they cured.
The right wing had similar damage to the ribs, but no center section or tip damage other than the tip rib its self.
The clamps are shown on the right wing, and the left wing is shown finished and ready to be recovered. I’m estimating the total working time for the repair, assembling the fuselage and recovering the wing will be just over 2 hours. Between 2 rolls of Ultracote and the wood and glue I spent less than $30.00 and will have most of the rolls left to help cover my Balsa USA Smoothie II.
