Subj: Re: Cork cement -- need a testimonial
Date: Thu, 24 Apr 1997 08:04:37 -0400

Good Morning,

I have replaced some corks and have dealt with 100's of clarinets in my
career. Leblanc cork cement does a great job of forming a bond. The
secret is apply cement to both the cork and the clarinet, wait for it to be
almost totally dry, then apply.

On a related issue: Cork grease has a great deal to do with how long a
tenon cork lasts. Try using a cork grease that isn't too "greasy" like the
Leblanc or Buffet label. The Selmer brand (Marshall Music label in MI.)
has a characteristic that soaks all the way through the cork and unto the
glue. The glue eventually lets go. I didn't believe it at first but tried
an experiment this year based on my repairman's advice. I can see
discoloring on the corks with the Selmer grease and some new corks had to
be replaced after 9 months. I found no problem with the Leblanc brand (or
should I say-brand x) No wonder when my repairman sees Selmer grease in a
students case he pitches it.
