[pianotech] let off gauge

[Marcel Carey]

Hi Jon,

 

You don't need various thichnesses of wood. You can have just one and use a rubber of felt mute to raise the hammer rail to where you want it with the piece of wood you happen to have. I use my grand voicing block for this. One less piece to carry in the bag of tricks.
