I have a guitar with a graphite nut that has a problem. The D string nut slot is too deep causing the D string to buzz on the first fret. the other nut slots are fine, and need no attention as the string height is acceptable, with no buzzing.
I know from reading Dan Erlewines books that you can sand a bone or plastic nut, fill the slot with the powder, and harden it with thin superglue, then file as needed. My question is, is this possible with graphite?? Will the graphite produce usable powder from sanding?
I don't want to go thru the whole trouble of installing a new nut if I can repair the stock one. Also, the neck has a 15.75" radius, so finding a nut blank might be difficult.
Thanks in advance for any suggestions.
PS. we don't have to get into a big discussion on "what is the best nut material" Okay?!

Your better off with just superglue. The bonedust is only there for aesthetics. Use a tiny pin head amount of superglue at a time. I advise no more than 2 applications of it. The other thing is it wont last forever. It will get you out of a tightspot for a couple of weeks, maybe a month. Eventualy the string will wear the glue away, particularly with wound strings.

Yes, it is possible with graphite (although in reality it is not graphite, rather, it is a polymer) and it does turn to powder upon grinding. Use a file to grind instead of sandpaper as you don't want the sand mixing in with it.

Advice from 2 of the forums most esteemed members is much appreciated!!
Good point about not getting sand from sandpaper into the nut slot. That would cause friction, which this type of nut is supposed to negate, right?

Right. It is, like I said, a polymer, usually impregnated with Teflon.
