[pianotech] let off gauge

[Jon Page]

What works well for adjusting let off on a vertical is a slat of wood
wedged between the rail and the hammers, supporting them at
let off or just a little bit away.  Then you adjust the button to have
the shank 'just' rise off the support.

I have various thicknesses of wood for this and have been
pondering an adjustable supporting jig.
