I had the same question. I also did the drill and fill method but I haven’t re-drilled the thickened epoxy filled holes yet. Given that the original hinges were already pre-drilled I was thinking that I could just drill them out in the center of the filled hole to get back to how they came originally (but now with the epoxy ring in the hole). I haven’t tried this yet because I wanted to see the tolerances of the hinge tabs and slots first.
I’m definitely curious what others or you end up doing.
