After 3 emails to David Thatcher I I have resolved some plans issues.
The lower longerons aft of the spar have inconsistant measurements and could end up with it too long by 3/8" (better than too short). By chance I built it correct. It's supposed to be 26 1/8" from the rear flange of the spar. That will allow you to get the rear spar 28.5" from the spar web. Also an angle intercostal on the spar is not placed correctly on the plans. I shows aligned with the F5 vertical but does not take into account the contour rib attached. Dave said to relocate just outside the fuselage skin. Oh, and the rear spar is 50.5" long. That is not mentioned anywhere.
I fabricated the brackets to attach the rear spar. Then the seat ribs got the FMN10 bearings installed and then fit and clecoed into the fuselage. I ordered a "tight fit" angle drill to make the rib attach easier. Will be here in 2 days.
Before I can fit the bottom skin in this section, the rear section is not aligned square (skewed by 1/4") I will rig a gin pole to pull it square while fitting the bottom.
