Sect 8-9 Step 1 & 2: Inboard Inspar Ribs riveted to Stringer and Web. Finally, beginning to put it all together starting with this sub-assembly.
Sect 8-10: Finished Steps 1 to 3. Riveted Front Spar to Ribs. (note: two center Inspar Ribs are not yet riveted to Spar pending Nose Rib assembly at same time...next section).
I tried to use Main Squeezer for all the ribs, but several configs didn't allow proper reach &/or interfered with the rib's flanges. I messed up one rivet, so after removing bad rivet, I switched to rivet gun/tungsten bucking bar...and it was easier.
