I have a bass neck which has threaded inserts however the inserts don't go in all the way. They're sticking out about between 1/16" and 1/8". It's on a beater body now so I just created countersinks in the body so they would fit. However, I'm getting a nicer MIM Fender body and would like to fix the threaded inserts before re-attaching the neck. I'm concerned that just backing them out and drilling slightly deeper holes will weaken them but if I plug them then re-drill the amount of the plug left will be minuscule. Will drilling deeper holes and adding wood glue be strong enough? I also have PL adhesive left over from building my Fearful which I could use instead of wood glue.
