Today I finished the back seat covering. Now it’s ready for some airplane noises.
After I finished the back seat I took a little lunch break. Fellow EAA 731 member Kevin Ball stopped by and we spent an hour or so talking about the airplane, then I went over to Bart’s to take a look at his avionics work and to return his bending brake. When I got back, I started preparing the ceiling structure for the skylight.
I also cut the old stringer supports down a little bit to effectively lower the roof line about 1/4 inch, after accounting for the thickness of the new tube that will be on top of it. I copied the spanwise tube sizes from the plans at station C (T3, 3/8 x.035), and the chordwise tube sizes from the existing tubes in that area (T2 5/16x.058). I chose that size since the spanwise tube at station C serves the same purpose as my new tube at station N- a forward border for the fabric and an aft border for the other than fabric.
Bob has also specified that another tube be added between station N and the x cluster for supporting the shoulder harnesses for the front seat passengers, if the shoulder harness is going to attach out in the middle of that big tube at station N.
I also did some measuring to decide on how far forward to take the skylight. One certainty is that this is a lot of effort to make a big hole in the roof, and I’ll have to carry sunshades to cover it up for a lot of the time.
