you do it your way, what works for you is not an accepted form of repair.
I would urge any one reading to NEVER use epoxy to affix any part to a guitar, especially any part that may need to be removed at some point in time.
I do not know of any Luthier who would use epoxy for anything but perhaps to fill a fretboard divot or a cracked bridge pin line on a guitar.
Those who do this for a living (me) would never, ever put anything in place on any stringed instrument using epoxy.
I don't work on imported guitars but if I did, not even those would get epoxy.
Hide glue or a simple dab of wood glue.
DMF, Acetone and other chemicals used to soften epoxy will eat any finish out here, be it shellac or a linked polymer.
Let's see, a chemical to soften epoxy which you then get to try and scrape off, perhaps ruining the finish, or a bit of heat and some water to remove a hide glued nut?
I will stick with what I was taught and what has worked for Centuries.
You can keep your many "advanced degree's".
Might look into getting one for common sense.
The nut takes very little to hold it in place when there is a good fit to the fingerboard and peghead. The string pressure alone will keep it in place.
Educate yourself...
