I agree with the previous replies, especially as regards TB III. But,..I have to add that I use a lot of "hide" glues. Hide glue is probably the best glue for gluing down rawhide or sinew, but it works well for wood to wood too. The faying surfaces need to be as close to perfection as you can get,and free of oils, but the resulting bond is quite strong. Knox gelatin is a hide glue and I guarantee you can find that. Rabbit skin glue available at most art stores and may be easy to obtain.
Epoxies work OK for splicing billets, but use the slow cure stuff as it's stronger than the 5 min stuff. Ron
