The nut slot for a CBG is ideally a smooth tight fit, 1/2 the diameter of the string deep. It should be sloped upwards so the highest point is the edge of the nut/fretboard. Like others mentioned, if the slot is too wide, it might vibrate in the slot and make a buzzing sound, which can be pretty loud. If it is too tight, the string won't slide smoothly when tuning... (you will hear a popping sound as the string stretches, then slides, stretches, then slides...)
A good cheap tool is at your local welding supply store, they are tip cleaners for gas welders. These are tiny, cylindrical files that come in various sizes in a small kit. Before I bought good (expensive) slotting files, I just used a sharp triangular file, then used an old guitar string to wear in the slot a little, or to check the fit...
Practice, don't be in a hurry... you'll figure it out...
I prefer to notch each string to it's own depth, so the top of the string is even with the top of the bone nut. So my Bass strings will have a larger & deeper cut into the nut then my treble strings. I use a small V-shaped kind of file, works great.

The highest point edge of nut, bridge side right, not tuner side?.
Thanks for the great information.
If the notch is too wide for the string you can get a buzz.
