My dad was a custom cabinet maker and I apprenticed under him in my youth. I chose a different path in life but a few things stuck with me. A glued joint is always stronger then the wood itself if done properly.
I use good old Elmer's wood glue or depending on the repair 2 part epoxy with dowels,biscuits,SS threaded rod and fiberglass where needed. Wanna get your adhesive deep in a crack? Use a vacuum bag they sell for clothes storage. Glue it, clamp it, put it in the bag over night.
