Nut Slot Repair

[Rob Beck]

Hi All, this is my first post on this forum. I have a problem that I hope you can help me with.

Whilst performing a basic set up on my acoustic guitar, I have managed to file one of the nut slots a little too low and have introduced a buzz when playing the open E string, and although this gives me the perfect opportunity to learn to create a new nut (something I have wanted to do for a while), I have a looming gig to get through before I will have time to do this!

I have read about a technique for filling nut slots using super glue and baking soda, which sounds like it will solve this problem.

My current understanding is that the ratio of medium viscosity super glue to baking soda is 1:1, but I have read conflicting reports on whether to mix the two together first or drop the glue onto the baking soda in situ.

Has anyone done this before, who would be able to talk me though the process please?

Many Thanks

Thanks for the comprehensive reply Paul and I'll definately look up the boom you recommend!
