Mystery Noise

[Vanderhoofven]

Dear Friends,

Many thanks to Newton Hunt, Les Smith, Jim Bryant, Avery Todd, Greg Torres,
Jim Coleman, Sr., Eugenia Carr, Jim Birch, Lance Lafargue, Kent Swafford
and NBWW@aol.com.  Thanks to your excellent suggestions, I now have learned
the new skill of rebushing damper guide rail bushings in the piano and have
a pleased customer.  My customer was also pleased with the wealth of
technical knowledge available on this list.  You are GREAT!

Thanks!
David
