What glue did you use? It can probably be fixed if that crack is not to bad. What you can do is one of two things you can fill pile a bunch of glue in there I and bind it all together, might have to re tiller. the best thing I can suggest is heat it up in a heat box nice and hot to soften the glue if it is some type of epoxy and separate be boo from the Osage completely resurface the clue surfaces rough them up removing all previous glue and re glue with urac. this will work well make sure to get plenty of glue in the cracked area. you will have to re tiller I'm sure you will loose poundage as well. If it was me though I would stick it in the corner of you work shop, build another one from scrap looking at that one along the way to remind you what not to do lol. That is what I do. I dont try to fix problem bows because you will find that you can make a shooter out of it again but wont be fully happy with it and over many more arrows it will develop problems again. also it is hard to tell but it also looks like from the pictures the glue surface of your bamboo swelled up and might have caused the problem.
