I’ve decided to put storage compartments in the two larger bays below the baggage floors. After doing some measurements and mocking it up in the computer, I cut a hole in one of the floors.
I fabricated a reinforcing ring that wraps around three sides of the hole. There will be a hinge along the fourth side. The joggle at the two ends allows the reinforcing ring to step up onto the hinge so that the corner rivets tie all three pieces together.
