Installing the Punchings

The height of the keys at their front edge is controlled by the cloth and paper balance rail punchings. On each balance rail pin, place a .012 [.30mm] paper punching (or one close to that thickness) from your assortment (see left photo below). On top of that paper punching, place a cloth punching (see right photo below).

The more punchings are used the higher the front of the keys will be. Conversly, removing punchings will lower the height of the keys. We will determine the correct amount of punchings to use under each key in Chapter Six.
