Yesterday I spent about 5 hours in the shop. Dimpled the l/h F-770 skin, countersunk the F-704H side plates, and cleaned up a few other small tasks. Today, I spent about 2 hours cleaning up everything I could think of that made sense to do before pulling the center section off to prep the upper longerons and the center section-tailcone interface. It occurred to me that the upper longerons are pretty floppy and just generally hard to maneuver when they're on the bench due to them being bent and curved in 2-3 different directions, so I went ahead and countersunk them all the way back to the baggage bulkhead frame. I also dimpled the vertical flanges of the F-705D side channels, although I couldn't get a squeezer on the lowest hole (highest in the picture below) due to a bolt being in the way on the back side. when I get this apart, I'll take that bolt back out to dimple. Seems like theres a ton of stuff like that, where you want it locked down tight for match drilling, but then you end up taking it back out for access for something else. You may notice in the picture that the F-705 is still just clecoed together at the top This is because I'm installing the "Almost a 14" kit during construction. The kit instructions assume you're installing in an already completed airplane and they have you drill out all those rivets to get the factory cross bar out, so I went ahead and drilled them out and put clecoes back in a while back. At this point, I'm ready to get the center section apart and the upper longerons out of teh tail cone for countersinking, dimpling, etc. We're having some family over for the Superbowl in a couple of hours (go Chiefs!). I'm going to grab my brother in law to help me take this apart before kickoff.
