I wanted to wrap up the ribs at station 69.0'. I marked and drilled the rivet holes to secure the double ribs and refit them between the spars. I placed and drilled the spacers and drilled pilot holes through them. Next was drilling the forward spar and rear spar holes using the 5 hole template on both sides (thanks Joe M.). I rechecked the spar level on both wings and used wing nut clecos to secure the spars in the wing stands.
