[pianotech] Damper tray block

[Jon Page]

While you're at it, check the angle of the underlevers. If they are too 
steep, lower the pivot hole.
I'll be doing that on an M today. The underlevers are pitched downwards 
so much that there is
excessive sliding friction on the key end felts. Fortunately the piano 
has not had a lot of use
so there are no trenches plowed outs.

I like to have the key lift the underlever to being parallel with the 
keybed at full keystroke.
This reduces the sliding friction to the minimum, near zero at full 
depression.
