Fabricated the rear seat rudder push tubes. When I originally took the parts out, nothing would fit together. I looked at the tubing but the walls were too thin to ream or anything. I ended up taking the bench grinder (with a scotchbrite wheel) and grinding down the rod ends until they fit in.
Used the drill press to drill the holes. For some reason the rivets that Van's provides always seem too long but they mostly worked.
