  I'm sure someone's thought of this before, so forgive me if my idea is =
unoriginal!

  For those of you who use Bill Spurlock's grand letoff jig, this should =
sound familiar.  Every upright has a built in let-off jig:  the hammer =
rail.  Today I was playing with a Hallet-Davis (Pearl River version) =
that's about 3 years old.  It needed let-off regulation in a bad way, so =
I experimented with the hammer rest rail.  On this particular piano, I =
could push it far enough forward so the hammers were close to the =
strings, even ON the strings.  Some pianos won't allow for that much =
movement, but this one did. =20

  I set a some samples for letoff, then pushed the rail forward to the =
point where those hammers would wink when I depressed the key.  I =
blocked the rail so it stayed there, then adjusted the let-off to make =
the hammers wink.  Worked like a charm. =20

  Pianos that won't allow for such free motion of the hammer rail may =
require something to clamp onto the rail for the shanks to rest on--the =
Spurlock jig comes immediately to mind.

  Hope this helps someone in some small way!
