Flying Cloud has the door within the main entry door, and I am rehabbing both doors. The hinge originally attached to the main door with some rivets and some screws (screw holes now are empty):
Similarly, the hinge originally attached to the door-within-a-door with some rivets and some screws (screw holes empty):
Can anyone explain why Airstream used the combination of screws and rivets? Aluminum rivets would be better, wouldn't they, in terms of future corrosion? The original screws had corroded considerably.
I want to insulate and close up the door-within-a-door, but if I am going to use buck aluminum rivets instead of screws, I need to do that first.
Thanks for any advice.
