"To properly fit the skin to the frame, a tuning fork had to be used."
I'd love to know more about this. —Preceding unsigned comment added by 219.78.87.74 (talk) 00:37, 11 February 2011 (UTC)Reply
It's called pre-stressing. The skin needs to be pulled tight in particular directions, and so there will be a precise acoustic resonance, much like a guitar string. The B29 was the first such construction. The wing frames were pushed downwards in a jig and then the skin riveted on. When the jig was removed the wings became straight although the bottom skin tension meant they would not bend upwards very far.203.87.118.239 (talk) 00:00, 17 February 2018 (UTC)Reply
