ABSTRACT:
Rectangularly-shaped wooden anchors are adhered by glue onto face surfaces of a wippen and a jack in a piano action. Each has a central annular opening through which a looped portion of a string extends for connection to a spring used to impose a spring force upon a repetition lever and upon a jack. Each anchor, made of wood, has a thickness of 0.12 inch or less and includes a slot extending to an edge to adjustably receive one terminal end of the string to provide the desired length to the loop in the string.
