Well, the non-silver composites used for fillings today do have
   phenomenal properties, but I thought they all needed a special light to
   cure them.

     A lutemaker friend did the work and I can't distinguish it from the
     original bone on the nut.
     He called it dentine. It seemed to be liquid and in a small bottle.
     Perhaps it's a sort of ceramic used for filling front teeth, but I
     admit I'm not sure. Perhaps a lute maker on the list will know.

     I have seen a similar problem when moving to smaller diameter
   strings,
     especially if the nut was filed with jeweler's files giving it a âv'
     shaped profile . However, what is 'dentist's dentine', some sort of
     magic epoxy?

       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?
       Best wishes

             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,
       Jurgen
