Up at 5am this morning to rivet the inboard rib into the right fuel tank. I scuffed the edges of all of the contact surfaces per the instructions and cleaned with MEK. Then I mixed up a batch of ProSeal (1.5 oz + .15 oz hardener) so I would have some extra as yesterday I had just enough. For these end ribs, I put on a lot of material as to avoid leaks. Everything went well, we only a couple of stubborn rivets, but no drill-outs. I also managed to prep and rivet (w/sealant) the tooling hole covers that go on the outboard ribs in both the left and right tanks. I hope to set those tomorrow and then I will finish attaching all the internals - attach fittings, reinforcements, vent fittings, return fittings, BNCs, etc. Those all get a lathering of ProSeal too. Then it will be time to close out the tanks with the attachment of the rear of the tank (baffle).
Setting the rib carefully into place so I don't loose sealant and make a mess.
