This may not be a huge mile-stone but my -7 wing panels are finally free of the wing stands / jigs after 300+ hours of work. It feels so awesome to have the first "bigger" pieces floating around my shop. I could not be happier with how well the top skins came out. We used a mushroom set & bucking bar method & low gun pressure while riveting the top skins & they came out absolutely flat & looks like a mirror. A big thanks goes out to fellow RV -10 builders / bucking partners Bill & Gordon!!!
