Brief Description: Finished fuel tank attach hardware fabrication.
After fabricating the fuel attach bracket hardware twice, I proceeded to match drill the angles with the F-717 lower longeron, F-713 auxiliary longeron, and F-902 bulkhead through the F-770 forward side skin. I removed the angles and clecoed the spacers to the anlgles and match drilled them. I then clecoed them all back to be sure all the holes matched ok. Charlotte deburred and scuffed the parts and now they are ready for priming when I do the next batch. They will be ready to install at the appropriate time.
I then decided to drill the 1.5" holes for the left step. I received hole cutters from Avery Tools and in short order the holes were cut. Much easier that tin snips and Dremel work. The left step torque tube had to be cut shorter also to make the plate flush with fuselage skin. The hack saw and grinder made that quick work. I made a reverse template to pattern the rivet holes to be drilled on the step plate after drilling out one rivet on the F-724 frame to get correct alignment for that column of rivets. Tommorrow I'll drill the step plate then cleco and clamp the torque tube to match drill the through the plate into the side fuselage skin.
