I primed the mating surfaces and riveted on the forward cabin frame channel attach angles.
I also countersunk the doubler and riveted it onto the channel using the forward holes. The aft holes will tie these pieces to the top skin and F-706 bulkhead.
I cut out the cover that I’m fabricating for the channel and drilled a series of holes with a #19 bit for #8 screws.
I riveted on some countersunk nutplates and screwed the channel cover on. Here it is reinstalled in the plane. I’m going to install a light here that can be used to illuminate the interior both in flight as well as during loading/unloading.
