Time: 8 Hours
Today started with riveting the seatbelt backing plates to the upper bulkhead.
Next up was to work on the rear baggage support structure including the ribs and rib angles.
Lots of final drilling and deburring with these parts. I next moved on to the passenger lap belt attach points. They have a beefy angle that has to be cut and shaped to attach the seat belt lugs to.
Those three parts need to be riveted together now so I deburred, scuffed and primed them, leaving the tips unprimed like the others so the paint doesn’t get worn off later while in use.
I will paint these gray later as they will be seen in the cabin. I then moved on to the next steps which was deburring the lower aft longeron, the aft middle longeron, the aft tail cone deck and its spacers.
The lower longerons are over 100″ long and took a while to debur the edges. The seat belt attach assemblies get bolted to the lower longeron and needed to be final drilled with the 3/16″ reamer.
So a long day in the Hangar mostly final drilling and deburring but it has got me to the point where I will be attaching the left and right tail cone skins as well as the bottom skins. It is really fun to see this progress.
