Finished up the wing tips by rivetting the rear ribs to the tips. This was a matter of countersinking the holes in the tip and epoxying and riveting the ribs in place. I alsow dressed up the trailing edge to cover up the gap left by the wing tip, leaving a hole for water escape. Also cut holes in the support boxes to allow water to escape, if any should somehow get in there. I also wanted to make sure that thse boxes were completely vented for pressure nuetralization.
