Bedding: the process of making sure each rail, back, center and front, are firmly seated upon the keybed for firmness of touch, lack of noise and resistance to changes caused by weather and heavy pedaling. The process involves making sure the back rail cannot move up or down but will freely move left and right. The front rail touches the keybed at all points with the keyblocks in place and the key end pins are not forcing the center of the front rail into the air. Sanding, planing or shim forcing the rail down or up as needed. THe center studs are then set to seat firmly on the keybed without raising the front or back rails from their secure positions. The art is in making this so. Newton
