Subject: Pietenpol-List: front seat back serves as a fuselage bulkheadRob-- I would at least reinforce the perimeter of your front seat area with saysomething like1/8" in plywood x 2" in an inverted U shape place perpendicular to the sides andalong the bottomfront edge of the pilot's instrument panel just for peace of mind--especially withthe longeron having been cut for your door installation. Just my gut feeling, no design orengineeringanalysis to substantiate though.Mike C. ________________________________________________________________________________

NOt a double door, but a single door on the front left.Now imagine the bathtub cockpit...no divider in between front and rear pits.I was thinking of closing the front door area to get the strength back and justgo with the bathtub design. With that configuration, I"m only losing the bracein between the cockpits.If it really bugged me, I could put a steel bar that is removable for entry andegress.Still kicking it around,Rob--------NX29NX, C65, Hegy prop, Blue/Cream flying!NX31TM, C85-12, GN-1, 90% done, Red/CreamNX30NX, Corvair, on gear, wings/tail doneNX31NX, Hatz CB-1, O-320B, on gear, ribs doneRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: front seat back serves as a fuselage bulkhead

Or I could just glue a bathtub in there...I like your idea: somehow I have to translate the torsional stress from side toside. Re-enforcing the sides and bottom of the fuse in a U shape at the rearcrossbrace would probably do it...sorta like a gunnel in a canoe.--------NX29NX, C65, Hegy prop, Blue/Cream flying!NX31TM, C85-12, GN-1, 90% done, Red/CreamNX30NX, Corvair, on gear, wings/tail doneNX31NX, Hatz CB-1, O-320B, on gear, ribs doneRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Thu, 13 Aug 2009 20:46:35 -0400 (EDT)
