The molding is giving up the ghost and allowing the crossbeam to pull itself away from the glass. I have fashioned a temporary piece of metal that basically hugs the top together. I'd like to use this idea as a permanent fix, but should I distribute the pressure over a few inches across the top, like a sort of grip pad? I don't know if all that pressure on a finger-tip-sized spot at the top of the middle of the glass is a good arrangement. Should I just use a wide piece of metal? The gap between the lids in only half an inch, so I'm kind of stuck adding weight distribution 'grip pads' of some sort, aren't I?
