Today I was able to get to the hangar to confirm the shape of the mask for shaping the fuel tank skins, I was close on the first attempt but I think the shape is improved now to the point of being ready to cut but I'll wait till all of the other jobs are complete on the wing. I installed the rivnuts for the inspection covers on the bottom of the right wing & commenced carrying out the intent of Service Bulletin 0014 Revision 1 on the bottom of the right wing. As with the centre section of the fuselage, I'm using Duralac as the faying surface sealing compound, leading edge rivets complete with half the trailing edge rivets removed now I just need to find the one rivet tail that escaped inside the wing! More of the same tomorrow.
