[pianotech] key position at rest

[Richard Brekne]

Thought I might add a couple other clues I have to go on.

Existing backrail felt is pretty thin. Not quite 4 mm thick.  Also, at 
some point someone has added 2 mm thick felt to the back key felts that 
raise the dampers.  I get the feeling I should be using a 5 mm back rail 
felt at the very least.

Thanks for any thoughts

Cheers
