Key Clamps

[Andrew and Rebeca Anderson]

Matthew,
I have to glue back on the occasional ivory.  I clean both the ivory 
and the key-top, then I coat both the ivory and the key.  Thirty 
seconds later I position the ivory and wrap a rubber band around the 
key and the ivory.  Back to tuning...half hour+ later it goes back in 
the piano.
