Official Luthiers Forum!

Hello there, am new here, and not really a luthier. I have an Ecuadorian bandolin, which has 15 strings in 5 sets of 3 each.
Far from any creditable luthier, or any luthier at all, I hope someone can give me some tips, and I can make the small fix that I need here.
The fret buzz is only on the 2nd string and the 15th string, and only at the first fret. All the other frets seem to sound fine.
Really hope there is a suggestion to; raising the slot for just the second and 15th string at the nut?
Don't want to get into messing with the frets at all, since all the other strings are sounding clearly.
I understand that people use "CA" (cyano-acrylic)..is that also known as 'crazy glue'? for filling in at the nut.
Please clarify if that is what you suggest using to raise these particular two strings to eliminate the first fret buzz.
Thanks for any replies and/or suggestions or re-direct to any luthier or forum that can be of help.

Have you replaced the strings in question to see if the buzz is still there? Welcome to the OLF, Dove!

Are the strings buzzing when played open, or when fretted at the first? If it is when played open it is likely the nut slots. On the other hand if it is when fretted it is likely the fret.

Thanks Alex for the welcome! The strings are hardly used, so don't think that's the problem.
Hello Brian! Thanks for your question. The strings buzz when played open, and not when held at the
first fret, or any other succeeding fret. I do think, as you said here, that it is the nut slots.
My idea is to fill these two slots in question, with a little filler.
Here's my next query: Shall I use a bit of "CA" with bone dust? Would that be a good filler?
Then, I can finely sand the surface to meet the proper level above the first fret.

Also, here where I live, it would just be the regular "crazy glue", and not something sold for luthiers in particular.
Appreciate your replies and look forward to a tad more info before I actually go for this. Thanks guys!

I'm no expert. But, sounds like the slot at the nut is too deep for the strings in question. Try a fill and re-slot.
This video from StewMac basically shows you the technique.

Some of the world's best luthiers put shims under the nut for fine adjustment. Why don't you try that. Jose Ramirez uses slivers of business card or index card.
