Would it adhere better to bone (or, shudder, ivory) than a hard plastic
   nut? Wood would be acceptable, too, I suppose.
   It might be that magic material to quickly build up a worn fret, too.
   Carefully done, of course.

            Could it perhaps be   Leonard, that the grooves at your nut
     at 5C
        was
            set up for your thicker unisson strings. 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, too have had issues with octaves on the 5th course
     of my 8
              course lute.   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!

            Hello there,
            I have an 8c lute now since 10 months and from the beginning
     I'm
            "unhappy" with the sound of the unison C strings on it. 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.
            Hoping for some suggestions,
