I just finished dimpling the skin flanges on the Front and Rear Spars (HS-702 and HS-603). I was somewhat surprised at the amount of bowing this operation created. Dimpling the flanges stretched the skin attach flanges to the point that the HS-603 bows 3/3" at mid span.
I am assuming that this is not uncommon?
I also assume that I should not try to straighten these? Have seen no instructions to flute for example.
Thank you in advance for input.
