An alternative to super glue based fillers I would suggest is an epoxy I used for many years in electron microscopes called 'Torr Seal', which appears to be still available. It is a 2-part epoxy, so it must be mixed before application, but it is incredibly hard because the filler is finely powdered sapphire particles and the epoxy itself is much stronger than superglue. Downside is that it is expensive ($50), although one tube will probably repair hundreds of nuts and it has a long shelf life.

Something similar happened to me on my 11C lute, when I replaced Venice twine unissons on F4 with equivalent thinner loaded strings. I heard a definite rattle. I put the Venices back and the problem went away. However later on my 3A unisson HT gut strings a similar rattle appeared, I hadn't changed the diameter, but perhaps some wear had slightly widened the groove or the neck moved a little. I could have changed to slightly thicker strings, but a lute maker friend said he could lightly fill and raise the nut's groove with dentist's dentine. This did the trick, so this solution for changing to octaves could possibly work for you. On my 7C lute, on 5C, I have Venice twine unissons and like yourself, I have been thinking of moving to 1.00 Venice bass and 0.52HT octave, but I fear a similar problem will occur as the lute originally was set up for the unisons so with a wider 1.00mm groove Also, I imagine perhaps wrongly, that a 0,52 Ht gut string will last a lot less than a 1.00 Venice unisson. Am I wrong about that?

I tried it several years ago, using an octave half the diameter of the bass (all in gut). But, whereas the octave g on 6th blended well with its bass, the octave c stood out, sounding jangly, almost as though I had a metal string on there. Perhaps it was poor (thumb-in in this case) technique? At any rate, I switched back to unison. I'm trying octaves again as a result of this discussion, same stringing. One thing I paid careful attention to was the height of the octave: it stood a mere half millimeter above the bass at the bridge, but enough that I was striking the pair of strings unevenly, with the octave ringing out quite plainly. I adjusted the bridge knot, what little I could, and the sound improved somewhat. Perhaps further work with RH technique will further improve the sound. Or--any other suggestions?? Regards to all, and Happy (US) Thanksgiving!

I changed the plain Aquila strings to round-wound Aquilas but to me it sounds quite the same. What I'm missing is the high frequencies that we have on 6c instruments with the octave string. In my mind I call the current sound "plastic-y". The maker of the instrument suggested to try out the Savarez early music strings but I do not think I would recover high frequencies with them. Any remedies that you have tried out with success other than "just get used to it"? An octave string shouldn't be a good idea because it would confuse voices.
