RV-8 Builders: In Section 8 of the builders manual (Page 8-50 for the 4/26/07 rev), Drawing 77, it appears that they are having you hold off riveting the floor stiffeners along the sides of the stick mount until *after* the floor skins are installed rather than before they are installed. Is this because there's no way you can get the floor skins into the right position once these stiffeners are riveted on? I'm referring to F-830C-1 Floor Stiffeners. That's kind of a bummer to have to try to rivet those after the skin is installed for obvious reasons, but begs a bigger question; what about down the road when you might have to remove the floor skins for some reason. Do you have to drill those stiffener rivets out too? Ugg...

Adding those stiffeners was one of the last things I did on my RV-8 which i s being inspected this Saturday. Those floors are a major pain getting in w ithout the stiffeners let alone trying them with. Attaching the stiffeners with the floor in place proved to be no big deal. I recall doing all mysel f. The main 'gotcha' when installing the floors is that many of us forget abou t the flap fairings (comes with wing kit I believe). If you permanently ins tall the floor before installing these fairings=2C you will have to use pop rivets to attach them to the fuselage. No big deal really=2C unless you ar e Oskosh Grand Champion bound=2C but still an annoying revelation. Also=2C the floors shoudn't be installed until you resolved locations for e lectrical items like aileron trim=2C comm and transponder antenae=2C wiring runs=2C pitot static lines=2C etc. I Pop riveted the floor as per plans. I also have nothing under them I need access too. You could use plate nuts in lieu of pop rivets=2C but at @ 20 minutes install time per plate nut you would need to remove the floors seve ral times to offset the speed advantage of the Pop rivets. As a 'gotcha' prevention strategy=2C I would suggest all builders wrap thos e stiffeners up with a labeled tie=2C and then tape them to the flap inters ection fairings. Regards=2C Vince H.
