MTM said:+1 for a thinner epoxy for wood repair. Not that JB will not work, thinner stuff will soak in better. If you have a marine supply nearby Git-Rot is the thinnest I know of that I have worked with. West System has one as well. You might consider drilling a hole from the tang area of the stock through the wrist and using your JB to glue in an aluminum rod. Will never break again.
