ABSTRACT:
A jig to establish the precise location of a piano key button upon a piano key which takes the form in the shape of a parallelogram with the sides being pivotable with respect to each other. Upon one of the shortened sides of the parallelogram shaped jig is an abutting plate wherein the abutting surface of the abutting plate is located perpendicular to the longitudinal center axis of the shortened side to which it is attached. Upon the opposite shortened side of the parallelogram shaped jig are a pair of aligning pins and the line interconnecting the center of the pins is located perpendicular to the longitudinal center axis of this shortened side member. The pair of pins are to be conducted through a longitudinal slot formed within the key button and to be connected with an appropriate opening formed within the piano key. The plate abutting member is to be placed in flush contact with or in line with the side of the fingertip portion of the piano key with the result being a precise locating of the key button upon the piano key. The key button is then glued or otherwise fixedly secured to the piano key.
