Hi Stabor, I did tighten the hinge on my old Elites. I VERY CAREFULLY pried up the disc at the ocular end of the bins (it is glued down), the disc that says "Elite 10x42 5.6* field, etc. At that point, to the best of my memory, there was a small set screw visible in the large flanged 'bolt'. I took this screw right out, took out the large 'bolt', put some 'locktite red, #242' on its thread, re-installed it to a tightness that gave me an acceptable tightness of the hinge re-installed the set screw, firmly, then put a thin coat of contact cement onto the top of the large screw, and the underside of the disc, waited for it to (almost) dry, then pressed it firmly into place.
(I should mention that the disc could be prone to bending, so I lifted it up a tiny bit with a very fine screwdriver, then lifted it the rest of the way with a knife, to try not to bend it.)
Hope this helps, John
