Today I devinyled the left F-770 side skin ( I had already done the right one). After deburring it, Karen helped me with the dimpling. She had to leave before we were done, but I was able to dimple the right F-770 side skin solo. I also dimpled the F-706 bulkhead below the main longerons, and the F-723 corner ribs and its associated clips.
Left F-770 devinyled and ready for deburring and dimpling.
