I'm making a mailbox out of one of those party helium tanks. It's coming along fine, but I cannot figure out a hinge for the door. The big box hinges that are narrow enough have quite a bit of slop in them and are the sturdiest designs when only one is used.
I was wondering if anyone has a design or know of a vendor that might have something that is fairly rigid laterally and narrow. Ideally it would mount on the inside but if exterior is the only way - so be it. Mostly if it can survive a mailman having a bad day, I'd be happy lol.
Thanks for looking.
