Brief Description: Forward Center Section Bulkhead assembly
Riveted 40 AN470 rivets joining the side angle to the bulkhead. Used the rivet gun and tungsten bucking bar. Set at 60PSI. Riveted all ribs to spar, and attached bolts with appropriate torgque. I used the small, non digital, torque wrench to make sure the AN3 bolts were torqued to 28in pounds as per the directions. Torque seal was applied.
