Hi Don.

I believe that any denatured alcohol or rubbing alcohol (did you mean =
denatured alcohol with at least 98 % alcohol ?) will do the job, =
foreseen that the glue used for the joint is soluble in alcohol, which =
is the case of hide glue.
I just wanted to point out that my previous post was not a joke.  I've =
tried the way Ric describes, probably with much less talent and =
patience, but as soon as I tried the other way, which I did not invent =
of course (who am I etc.) I considered it immediately a much better way.
When the piano is upside down, the alcohol can soak much quicker into =
where it does it's job : at the joint; and from above, it is very easy =
to apply the exact minimal pressure that loosens the joint without =
risking to damage the panel.  And you don't need to wait two days : I =
got my board neatly out in less than half an hour, so no need of rags =
protected in aluminium leaves to avoid that most of the alcohol =
evaporates too quickly.  Just remember : no heat with alcohol.  Ah, yes, =
I was talking about a grand piano.  Never tried to put an upright upside =
down.

Best regards.

St=E9phane Collin.

  I simply asked for the PTG Journal issue of the article on using =
alcohol as a technique
  in soundboard removal.  I have yet to have someone identify that for =
me.  However the
  "soundboard removal" topic has taken off in a completely different =
direction.  Having=20
  removed many boards by beating them out, I would like to try this =
technique.  By the way,
  I believe it was either denatured alcohol or rubbing alcohol.  Anyone =
have an answer?
