I cut the bottom and middle longerons about 1/2" oversize with my die grinder and slid them into place.
I lined it up with the center skin with the match hole and then drilled along the main longeron lining up the edge of the skin with the vertex of the longeron. Then I drilled up (down as jigged) the rear cabin rib. I drill stop on the bit so that I would just drill through the rear skin and not the rib that was behind it. This combined with drilling and then clecoing one hole at a time kept me from enlarging any of the holes that were already in the rib (or I was just lucky).
Then I drilled the remaining ribs from front to back. All of them except the second last were already lined up with the flange centerline showing up in the holes. I had to loosen the 2x4 inder the second to last one to get it to line up. Fortunately the notch in the longeron was wide enough to allow the rib to be pushed back about 1/8".
Then I drilled the middle and bottom longerons (every fourth hole on the bottom one). I drilled and Monica came in behind and put in a cleco. Both of us working together knocked it out pretty fast.
I know it is only an illusion but it seems like a lot of progress is being made. It is beginning to look like an upside down fuselage.
