Rebuilding a piano part 2

Continue from part one

After soundboard Has been replaced, the bridge is taken off the existing soundboard and a paper tracing is made of the location of the bridge pins.(this is where the strings go thru and transmit the sound to the soundboard)the pins are then pulled off and the height measured. Next step is to cut a portion of the top of the bridge off to get rid of any cracks and or splits on it. New maple cap is made and glued on and shaped to the original shape. WhereThe string and bridge Meet a proper "bearing" is   Important for the sound to transmit from the string. The string has to press down and exit leading down from the bridge, too much and the sound will die too soon not enough and the Sound won't transmit to the bridge and soundboard.
