Since I put two extra conduit runs under the baggage floor area yesterday, I decided to go ahead and close everything up. I'll leave the seating area floors unriveted until late in the project since there will be a lot of wiring and potentially a few antennas mounted under that area (the front seat floors are removable, but the aft seat floors are riveted down). The baggage floors are mostly pop riveted, with the exception of the nutplates for the center tunnel screws.
The rear baggage bulkhead is made up of two corrugated sheets that screw into the 706 bulkhead. I matched up the pre-punched screw holes on the bottom edge. There area no screw holes or nutplate holes in the sides/top of the 706 bulkhead. I clamped the sheet in place and drilled the main screw holes up the sides.
After the main screw holes were done, I drilled the rest of the mounting holes for the nutplates, then deburred, dimpled and riveted on the nutplates up the side and in the center channel. There are still a lot more nutplates to do, but I have to finish the top part of the bulkhead wall first.
The larger bottom portion of the bulkhead wall pretty much stays as-is. The top part has to be cut to match the curve of the top of the fuselage, and all of the nutplate locations laid out based on dimensions shown in the drawings.
