After a couple of attempts to make a one-piece inboard baffle, I broke it into two pieces. These were much easier to fabricate. The RV14 shows the left inboard baffle riveted to the floor, but I don't think there is any way that the whole assembly could be installed. I elected to used nut plates and screw the two pieces together.
I am pleased with teh air box (snorkel) mounting to the baffle system. It is time to epoxy the assembly together.
