Today I completed all of the #40 holes through the top skin and ribs. Next I need to drill through the rear spar and the main spar. For that process I plan to lay the wing flat and check the twist again with a level. I drilled the #40 holes through the rear spar and then leveled the wing on the bench in preparation for fitting the leading edge skin. Next, I got down the leading edge and started on the fitup.
