After the riveting was completed on the F-1206G&H baggage ribs, the whole assembly was flipped over so the F-1224 baggage floors could be riveted to the F-1206A bulkhead and F-1206H baggage ribs followed by the instillation of nutplates in the areas where the access covers will reside.

At this point the plans instruct the builder to assemble the pulley brackets and flaperon mixer arm assembly. These components will be installed on the seat ribs marking the beginning of fuselage construction forward of the center channel. The pulley brackets are comprised of F-1250-L&R pulley brackets and F-1220A&B forward and aft intercostals which are normally riveted with LP4-3 pop rivets. Access for the pneumatic squeezer was good, so the pulley bracket assembly was riveted with AN470AD4-4 solid rivets in place of the LP4-3 pop rivets.

The last item worked on today was the flaperon mixer arm assembly which is comprised of quite a few parts. The F-1220A&B forward and aft intercostals and two F-1218 flaperon mixer brackets are riveted together to form a box of sorts which becomes the mounting platform for the F-1219A&B flaperon mixer arms. Access for the pneumatic rivet squeezer was acceptable, so the F-1220A&B and F-1218 parts were riveted together with AN470AD4-4.5 rivets in place of the LP4-3 pop rivets. After the parts were riveted together, the F-1219A mixer arm received two nutplates and was then bolted onto the assembly along with the F-1219B mixer arm using a couple of bolts, some washers, spacers and a nut that accommodates cotter pins.
