Aligned frame to rear skin and drilled 3/32" holes in ribs per page 3 of Section 6-T-5 of assembly guide. When marking rivet hole lines on rib flanges it is important that they all be refereced and drawn off the same datum plane (rib face), NOT the edges of the individual flanges. This will ensure that all of the lines are equidistant and parallel to the rib face. See this EAA video for more on this topic - http://bcove.me/q9l9j16s.
Clecoed skin to ribs with everything appearing to align properly. Tip rib should arrive from ZAC tomorrorw so I can finish rib drilling.
