Does anyone know a quick-fix to level the strings on the nut?

It's a 2'nd hand parts-caster made from old Fuji-gen parts, and I'd really like to avoid removing the old nut (it's not coming out easy), was thinking to try giving it some epoxy or super-glue in the slit for the D and B-string, but I'd love to hear any ideas before I start destroying one of my guitars :-)

I think the classic method is bone dust mixed with glue. Though its not as good as a new nut. Here's a thread. Sounds like bonding to plastic like nylon is more problematic.

Classic repair shop trick is baking soda and super glue, just tape around the nut so you don't fuck up the fretboard, when it dries in like 15 minutes you can file it back down

are you happy with the level of the strings relative to the first few frets? if so, maybe you can just sand down the nut from the top.

Thanks for the reminder to cover the fretboard :-)

I'd like to get as high as possible, I want to use it as a designated slide-guitar and I'm trying to avoid the rattle.

Nice thread, really informative.

Yes, this it definitely a temporary fix :-)

Thank you all for being super helpful :-)

I went with the baking soda and super glue

The G and B-string could also use some adjustment, but for now it's playable.

OP used your advice and fixed his nut, but I thought I'd leave this video here for anybody else who runs into a similar problem. This is the process you described with extra tips and bits.

why would you make a new nut when you can save your old one like this? in minutes!

Sorry so late. You can likely fill the "slits" with a mixture of baking soda and superglue as long as you don't mind the color mismatch, and then file out new ones to the correct depth. Epoxy will just give you a bad day
