Groovy sometimes; nutty others--and only a distant bridge to unite them. My understanding is that a depth of only half the diameter of the string is necessary with radius only slightly larger than the string. I prefer a little deeper on the chanterelle of my ren. guitar since it loves to pop out but then I get into issues clearing my first fret if it's too deep. s

Similarly how deep / wide should the grooves on a Viola da Gamba bridge be? What do the builders on the list have to say?

Depth should not be a problem; in fact, near the nut the upper surface of the octave should be lower than the bass. BUT--I had not considered looseness across the groove. I'll look into that.

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??
