Epoxy, even the five-minute kind, is really a better solution for this than carpenter's glue.

Just curious why is epoxy a better solution for this application ?

I've read tests done on various types of wood glues used to make furniture joints.
In those tests where the joint was deliberately broken to test strength, the
wood itself would fail at the grain before the glue did.
