Marked all the flange centerlines for the right wing rear ribs and nose ribs in preparation for drillling them out. I then fit the front of each rear rib to the main spar which requires a bit of joggling/crimping to fit between the main spar flanges. Once they were fit, it was a simple matter of finding the centerline marks through the pre-drilled pilot holes in the main spar. ...except for ribs #2 and #4 - their pilot holes are covered on the front of the main spar, so you have to map the pilot hole positions on the back side of the rib flange and then blind driill into the main spar. I figured out how to do this with the left wing (May 10, 2013 entry) so it didn't take nearly as long this time. Still, it was somewhat time consuming.
After drilling out all the front flanges, I lined up the rear flanges with the rear channel and clamped it in place.
