Subj: [kl] removal of tenon socket ring
Date: Sat, 16 Oct 2004 17:56:47 -0400

Dear Clark, Walter and others,

The long story on the tenon socket ring which i hope will answer your
questions and clarify my intent:

The instrument is a 70's vintage Buffet Bb R-13, with a hairline crack
starting at the edge of the tenon socket (top side of the clarinet and
continuing into the first tone hole socket( Bb-F). This crack had been
treated with "super glue for wood" some years ago and the instrument
has been an excellent performer over the
years with many who tried the horn commenting on the power and projection.

Recently there have been sporadic instances of clarion F not sounding
clearly and an associated air/hissing sound. I am assuming that perhaps
the crack has opened, or at least is no longer properly sealed. ( the
crack is still just a hairline you can see and feel with a fingernail.)

I called Walter G. intending to send the horn to him for repair.
Unfortunately he does not perform crack repair.

I was intending to remove the ring and recoat the crack with "super glue
for wood" after removing any remaining old glue residue, and reseat the
ring shimming the ring as necessary.

I am aware of the following: There is not enough wood in the area
involved for pinning as there is very little "bore area" between the
very thin area of the socket, and the tone hole.

It most likely would be possible to band the area just North of the tone
hole...but there is really not much thickness there to cut a relief for
the band, and the band would run directly under the bridge assembly. Of
course the bridge could be adjusted to account for the metal band beneath.

Realizing that the leak most likely does not occur in the socket area
which is filled with the tenon from the upper joint, but rather in the
bore leading to the tone hole or in the tone hole itself I have cleaned
these areas of old glue and recoated the crack as previous.. I have not
removed the ring , but instead recoated the area inside the socket where
the crack is not covered by the ring.

So far the horn plays fine, but it may be too early to tell..I await the
results after a few temp and humidity swings.

Clark , I would still like to know of your technique for ring removal if
you are inclined to share. My one caveat on my horn is removing the
ring may release the pressure holding the crack closed. .. it could be
this very same pressure that makes this ring stubborn.. it is also
possible that a previous owner or repair has glued the ring in place to
help hold the crack.

Any thoughts and suggestions are welcomed.

Thanks,

Dave G
