While PAt was home from school I pressed him into service for a rivet bucking session. I had delayed final riveting of the upper fwd fuse until I had all of the firewall and sub-panel wiring figured out. It turns out that most of the holes are already drilled, and that delaying any longer only postpones needing to find a goo flexible rivet bucker. So Pat got the honors, and with his help we got all of the rivets on both sides that join the upper fwd fuse to the fuse, and also the AN4 rivets that join the 3 ribs to the firewall, I was concerned that due to the Faux firewall, I might end up putting some good sized 'smilies' on the firewall, but that didn't happen. I was also worried that we might not be able to get to all of them due to the engine mount being installed, but, while a couple required driving them at an angle with the swivel head flush set, we were able to get to them all. When that was done I finished riveting the fws portion of the upper fwd fuse skin to the firewall and the cowl attach hinges.
