Today, my father in law helped me to debur the #2 FUS 337 side panel. While he worked on that, I removed the channel, supporting gussets, angles, and the doublers near the top to debur, clean and prime. In addition, I dimpled the #5 bulkhead so the door would fit flush. After he left, I riveted the #1 and 2 FUS 337 side panels, except for a few areas where I still needed to do some work.
