Continued seat pans and other cockpit items

August 25, 2015 – The seat pans are ready to install.

I painted the seat pans and a couple of other cabin items. I also remembered to make the hinge pins for the seat backs. Here are the pins and two of them fit inside a hinge half.

I riveted the hinge halves to the left and right seat pans.

I also installed the nutplates on the F749 baggage compartment sidewalls. These panels are removable. I set them in place with no screws for the time being.

Here are the seat pans set in place, ready to install. I have a call out to my EAA Tech Counselors to see if anyone wants to look inside before I install these, since they are riveted in place. This is pretty cool…

Fitted F749 baggage compartment side panels

August 20, 2015 – I also fitted and prepped the removable side panels for the baggage compartment. These panels give access for some of the flap mechanism.

The top flanges of these panels have to be trimmed. There are notches that indicate the location of the trim. I marked the lines and cut them with snips, followed by a scotchbrite pad to clean everything up.

I later prepped the panels for paint.

Finished baggage compartment bulkhead

August 20, 2015 – I finished the baggage compartment bulkheads this week.

Since I had all the screw holes back-drilled through the F706 bulkhead, I needed to do the rivet holes for the nutplates. I took the bulkhead panels out, and used a nutplate jig to drill all the rivet holes, then I installed all the nutplates.

I drilled and installed the wear blocks for the shoulder harness cables.

Baggage compartment floors and bulkhead

August 12, 2015 – It’s been a while since I posted anything. The last work I did was just before Oshkosh. Then we got back and it’s been too hot to do much of anything.

I did get my throttle quadrant at Oshkosh. Got the DJM center mount throttle quadrant. I also ordered an Andair fuel selector valve.

I started on the baggage compartment floors. I realized that I had installed the nutplates in the two center ribs where the tunnel covers go, so I had to remove those nutplates.

I made sure all the holes in the floor panel were drilled, then I primed and painted them. Here they are clecoed in place.

These floors are pop-riveted in. That was pretty straight-forward. The aft flanges are solid-riveted and have nutplates installed.

I decided to try to get in and lay on top of these panels for easier access. In hindsight, I should have put a board in place for a little more support. It went OK, but there is one small buckle in one of the panels. The rest of the structure is OK. I ended up taking off the top skin so I could reach over to get better access.

I took out the four gussets between the longerons and the two bulkheads. I cleaned them up and painted them. They can go in anytime.

After the floor panels were in, I started on the aft bulkhead panels for the baggage compartment.

The lower panel is simple; just screw it in at the bottom and drill the holes through to the F706 bulkhead.

The upper panel is a little more work. It is just a raw piece of aluminum that’s already corrugated. The corners have to be trimmed to a 8 1/2″ radius. I marked that radius…

…cut it to shape, then cleaned up the edges.

081215013 081215014

I marked the locations of all the screw holes, and the locations for the cutouts where the shoulder harness cables will pass through. I piloted the holes to #30, then clamped the bulkhead in place and back-drilled the holes to the F706 bulkhead.

That was a good place to stop for the day.
