Backriveted stiffners to LH rudder skin. It was so easy. Learned how at George Orndorff's class, then practiced on the practice kit. Jake and I destroyed the practice kit by over pounding so the trick was to back down the air pressure big time and do it lightly. better to under do it, check with the guage and hit it again lightly if slightly underdone. Not good to pound it to death!
