Next up was cutting the tank stiffeners. This wasn't too tedious, just connect the notches with a sharpie, cut, and deburr. The small angle pieces in the bottom photo get riveted to the underside of the fuel filler flange and hold the fuel tank vent line in place.
Its always a little bittersweet starting on the first page of a brand new section. On one hand, there is excitement because you are one step closer to completion; and on the other it is somewhat dreadful because you are on step 1, page 1 of god knows how many.
Just like so many other sections, the start of section 18 has you prepping, cutting down to size, or locating holes in parts for later use in the section.
Measure twice (or 15 times) cut once really applies here. For the life of me I couldn't figure out to how make the threaded flange fit the drawing's specs. Then the light bulb went off and realized my measuring skills were not up to par during this session. One thing I've had to learn during this project is: If something doesn't go together right or just seems "off," stop and walk away (or go to VAF) and come back later.
