Remove Octave Square

The octave square design is a hard steel rod that travels through a soft brass part. That part (the square) then connects to the octave lever. This mechanism is the first on Bueschers and some Conns to have lost motion and wear. By machining a small part to replace the steel rod and the octave square, lost motion is avoided and longevity of the mechanism is achieved.
