Hi, Greg If you can close it with a C clamp, how about filling the crack with the heat-thinned epoxy, like I described, and then using the C clamp on it for a day or two? You wouldn't need to fill the crack to the brim if you're going to close it, just get some thinned-by-warmth (slow set) epoxy coating it all the way along. Sounds like very little work, and it might do the trick. The heat might speed up the epoxy set, so I wouldn't hang around -- just get it in there fast and clamp it.
