A photograph of the break would be extremely helpful though from what you describe some pining of the joint may also be of help in providing a good sound repair. As for adhesive's my preferred type is slow set Epoxy (this adhesive takes the rush and angst out of getting the joint assembled perfectly, also giving time for cleaning up) because it has been in common use for some sixty years now and still holding stock repairs together in the case of my own guns fifty years. More modern types of adhesives have not been around long enough to prove to me that things wont fall apart in the future.
