Collapsing the nut
With your slot cut most of the way down the nut, you should be able to grip the nut with some pincers (fret cutters in this image) and apply pressure. And it should collapse. If you’re lucky, it’ll collapse cleanly into a couple of pieces that are easily removed.
Thereof, are guitar nuts glued?
Is it necessary to glue a guitar nut in place? Gluing the nut is not completely necessary, the pressure of the strings and the friction between the nut and neck will hold it in place. However, you can use a few drops of white wood glue to fix it in place to prevent it falling off when changing strings.
Subsequently, can you replace the nut on an acoustic guitar? Different materials will influence a guitar’s tone, and a poorly fit nut will greatly affect playability. For one reason or another (worn slots, a change in string gauge, complete breakage, a need for different string spacing), a nut will occasionally need to be replaced, and many guitarists can do this themselves.
Considering this, how do you fix a broken guitar nut?
Dip the edge of a piece of paper into some superglue then carefully feed it into the nut slot. Allow the glue to dry then repeat the process until the slot is filled. You can now re-cut the nut slots.
How do you loosen a tight nut?
How do you remove a glued nut?
If the nut has been over glued, it may not budge using the tap method. In this case you can saw (with a small fine saw) along the length of the nut nearly all of the way through. Then break the nut out by gripping it with a pair of pliers, collapsing the nut into the saw cut.
