Interesting where this experimental build brings me. Did some research on 6061 t0-6 ductility and understanding of the process. Perhaps a heat gun and a cold wet rag might help? I don’t know what else to do at this point other than abandon it and get a new skin but then hopefully my holes will line up if not then, I’m in even more of a mess!

How ‘structural’ are we talking here? I mean we’re putting holes in the leading edge for pitot tubes and landing lights. Perhaps that’s my next topic of research, aeronautical structural design!

I had a leading-edge skin that was de-burred, dimpled, and ready to rivet. It got badly bent by a visitor that couldn't keep control of his feet and it couldn't be saved. I got a replacement with the same worries as you. All the holes lined up with the dimples falling into place perfectly.

CNC machines to the rescue.

The wing skins are VERY DEFINITELY structure. do not even think about using high heat on them.

Thanks for all the insight everyone! I’m going to stick with rule #2 of my guiding principles of don’t cut corners/do it right. New skin on order.

I guess I will start making flaps and ailerons while I wait.
