Big day building I first center punched and drilled the lower outboard hat sections finishing up the hat section rivet lines. I then drilled to #30 the left and right wing to include the ribs at station 69.0 and 144. I got to use my long reach clecos to secure the upper spar caps. Lots of drilling and shuffling clecos but my wing skins are drilled!!! I also cleaned and dimpled the upper ourboard skin stiffners. (short ones) I will prep and dimple the long upper skin stiffners next session.
