After the old soundboard is broken out of the piano, a fair amount of wood and glue residue remain. The rim gluing surface needs to be cleaned in preparation of installing the new soundboard. Chisels are used to remove the large pieces of wood residue with extreme caution so that the original rim surface is not damaged. Then the surface is soaked with a special water solution that softens the old glue so that it can be scraped from the rim glue surface.After this process is completed, the rim is left to dry overnight after which the surface is lightly sanded and any repairs that are needed are done.

Removing a soundboard from a piano is the no turning back point in belly work. The soundboard is glued to the piano inner rim and needs to be "broken" out of the piano. I take great care in removing the old board as I use it for a pattern in making the new board. I endeavor to replicate the old board, and make improvements where possible. The pictures show the removed board.

Removing the cast iron plate in a piano can be a bit un-nerving as it weighs several hundred pounds, and could cause damage to the piano if improperly handled, or worse yet, injury to the technician removing it. An electric hoist makes the job a bit safer.
