Removing Piano Action from Duo-Art Grand Piano
By John A. Tuttle

Hi All,  To those who have encountered every kind of grand piano with
a Duo-Art player mechanism, you know that there are almost too many
steps to put it all down in writing.  This is especially true of the
units that require the removal of all of the levers in front of the
piano action.  Taking the action out, and putting it back in is about
a three-hour job if you're careful and plan to put every single part
back exactly where it came from.

Personally, I can't over-emphasize the importance of keeping things
in their correct place.  I use a large piece of cardboard and poke the
screws into the cardboard along with the piece the screws hold in place.
This way everything stays oriented correctly.  Care must also be taking
when putting everything back together, as the felt overlays in the
linkage brackets must be in their correct positions.

Compared to removing the linkages, the rest of the job is fairly
straightforward.  The only advice I'd add is to make up a 'dummy' board
the replicates the tubing layout of the tubes that go through the
action.  Just take a strip of wood and drill the appropriate number of
holes in the correct pattern.  Then glue straight nipples into that
board and connect the tubes to that board as they are being removed
from the piano action.
