I recently got a good deal on an Olympus OM2n, and lo, the hotshoe is cracked. I understand this is a fairly common issue. The hotshoe still works somewhat, but the cracked base compromises its register with the angled pentaprism housing. I very carefully applied some CA adhesive and clamped the crack shut, but I'm not optimistic as to its permanence.
Any tips on fixing cracked OM hotshoes? I'm thinking either a zip-tie or safety wire tied around is the next step.
