After the soundboard panel has been assembled, and rough cut to shape, it is dried to 5% EMC. While the board is drying, the ribs are cut to dimension and length, and hand fitted into the rim of the piano.
The dried board is hand fitted into the inner rim, and then is indexed to the ribs. The old board is then indexed to the new panel, and the necessary holes are drilled into the new panel, using the old board as a guide. The rib lay out is transferred onto the new panel, and the panel sealed with shellac.
Finally, the ribs are glued to the new board, using the index holes to locate them so that they will fit into the piano rim at their proper place.
