Access cover mods for oxygen fill valve and rudder pedals

I came up with a way to attach the oxygen fill valve to the seat back brace closetout, using a couple angles to center the gauge through one of the openings:

I also dimpled all the floor attachment holes on the ribs, in preparation for attaching the floors (but am still waiting for the 5" GripLockTies to attach conduits before I actually rivet them):

Once the rudder pedals were installed, I made the openings in the forward tunnel cover for their arms, and split it in two for ease of installation:

That gave me a rough initial cut that then had to be significantly enlarged to give clearance around the pedal arms:

I then needed to make a splice between the two parts - I cut a piece of .040 slightly larger than F-1051G, and copied the hole pattern from that part:

After deburring and primer, I riveted it to the forward section, and also added a bit of edge protection so there's no chance of the brake lines rubbing against the metal on the forward opening:

Total access cover and floor panel rivets: 306
Total access cover and floor panel time: 27.3h
