The turtledeck got a little banged up in moving the airplane, as the clamp we improvised to keep the rolling door up was not 100% effective. This afternoon I worked on the skin. As you can see, I drilled the rivets that join the port and starboard skins, and tie them into the C-channel that forms the "spine". Since the Bottom Aft fuselage skin in not on yet, I can (barely) access the underside to "sister" the buckled "spine" - today was about persuading the skin back into alignment using a "Pops-A-Dent" glue pulling tool. It's taking some careful hammer and dolly work as well as this tool, but I'm getting there, without having to re-skin the aft fuselage or fabricate a complex insert. The hot melt glued "dolly" literally pops off the panel when you screw the center knob to the limit.

ALSO installed another inspection port cover plate.
