Hard to separate work on the AC from the baggage area. It's all moving toward the common goal which is to close out the floors. Weather was unseasonably warm this week so actually some priming done after work. Got the various AC hose doublers and a few other miscellaneous pieces. Having trouble with gun though and the finishes turned out pretty poor. Just getting a lot of trash in the paint and gun keeps clogging up meaning ithe gun is dirty somewhere. finally found the culprit and cleaned a part of gun not mentioned in the manual, but I found some gunk. Hopefully that fixes it. Will need to sand and respray some parts. The small doubler parts were salvageable and I installed the two fuselage former doublers as well as the tunnel doubler for the AC hoses. Then worked a bit on the baggage access cover. It's going to be removable so I installed nutplates in the baggage floor. I also drilled the #8s for where the top attaches Into the longeron. I experimented with tapping those holes instead of nutplates, but I think I'll probably just go ahead and nutplates them. Slowly coming together.
