I've not had any bow laminations fail using the poly glue. And I done a number of them. But none of them were Osage bows either. Oil in the wood isn't compatible with the poly glue. It's not the best glue around for lams IMO but it does work well if both works are properly prepared. Good thing about this type of glue is that it'll take a lot of heat for straightening and such. But mostly I use the poly glue for arrow footings.-ART B
