Hi Sarah.

I just learned two good tricks about those trichord dampers.
1=B0 use Yamaha damper strips.
2=B0 make a kink at the agraffee in the two outer strings so to increase =
the distance between them and the middle string.  Not much is needed, =
and the damper will sit much better. Do this of course when the strings =
are tensionned at the right pitch.

Regards.

  Subject: after-ring in new dampers


  Hi all,

  I just got finished replacing a lot of moth-eaten felt on my old =
Wissner, including of course the damper felt.  Most of the dampers sound =
great -- not too abrupt/whumpy, but not too sloppy either.  No =
"whooshing" or anything.  The only problem is the split wedges I'm using =
over those wound trichords that all you techs love so much.  (Honesly, I =
think these notes sound fine -- very "ballsy" and not poorly behaved at =
all.)  The problem is that the strings are spaced so closely that the =
little wedges don't insert adequately between them.  (The same wedges =
work fine for the plain wires in the lower tenor section.)  After =
sitting overnight, with the wedges gently "pressed" in place between the =
strings, damping was OK, but not great, for about 30 sec or so of =
playing.  Then the after-ring started up again -- not BADLY like the =
night before, but still noticeably.

  QUESTION:  Is this the sort of problem that will go away by itself, as =
the new dampers continue to seat?  Or am I using the wrong wedges?  Or =
perhaps I should "skinny down" the tips of these wedges by filing their =
inside surfaces with an emery board?

  Thanks for any advice!

  Peace,
  Sarah

  PS Don't y'all go sayin' no bad stuff 'bout my trichords!  It's a =
damper problem, not a string problem!!  ;-)

  PPS How long will gelled hide glue keep in the refrigerator?
