Seat pans & misc

Hours: 2.8 | Posted in Upper Fuse & Skins

Worked on a bunch of odds ‘n’ ends tonight:

  • Marked and drilled the seatback attach hinges (hint: mark & drill one, then use cleco-clamps to attach it to the next and use it as a drill template), then drilled them to the seat pans.  Back-drilled the aft hinges for the rivets that attach to the seat ribs.
  • Trimmed the necessary eyelets from the hinges.  First use of the bandsaw on this project…it really cuts the aluminum like the proverbial butter.  A little filing, a brush on the scotchbrite wheel, and they were done quickly.
  • Removed the aft skins from the fuselage and set them aside to be prepped for primer and later riveting.
  • Installed some snap bushings in the mid-tailcone, where I couldn’t reach earlier with the skins on.
  • Squeezed the two forward-most rivets on the aft deck, which I didn’t do before due to their proximity to the bulkhead (which I also removed).
  • Deburred the harness cable attach bracket holes in the longerons.
