It's like laying rebar in a concrete pour. Fiberglass mesh, anything that can add strength and stabilize the joint.
We've rednecked plastic intake manifolds, cam covers, etc., like this to keep a test engine running.
I've reinforced cracked wood stocks with epoxy and brass screws through the crack. Saw the screws off, trim flush, polish, and they look like small brass pins. You can antique the brass to help it blend into the wood too.
Note: Gunsmiths will be losing their minds about now. I am a redneck hack, who has learned how to cobble most anything. I am sure others can offer better solutions and I defer to their better judgment.
