I saw somewhere (probably here) that a builder had his oil door opening inward. You just pushed on it and the door hinged down into the cowl. I think it was hinged on the outboard side. He had inserted springs in the hinge to exert closing pressure while on the ground but air pressure kept it closed while flying. The advantages are lightness and smoothness - there is no latch and a piece of standard hinge with one or two springs inserted is all that is required. As the flange is molded onto the back of the door instead of around the opening, it stops the door from arching up in flight.The only disadvantage is that your sleeve is constantly rubbing the paint job on the outside of the door as you work inside.
Can anybody here provide a link to information on this set-up?
I would also be keen to hear opinions on whether this would still work with the SJ plenum I have bought. Maybe it is suction from low pressure over that area of the cowl that keeps it in place rather than high pressure from below?
