I have been thinking of making the cabin floors removable and I also have a smashed rivet I need to look at, so I decided to drill out one panel just to test how easy it was. The pulled rivets is a different beast than the standard ones, they require a slight different technique. I went fine, I got the access I wanted, but I am not 100% certain I want to remove 3 more panels. I'll sleep on it a little.
