Thing of it is, do you know the specs here. How much deflection per =
how much
side pressure? I'm guessing that the only test people really use to =
check side
play is the old screwdriver blade, or brass rod, under the shanks gang =
style
to check for winking hammers indicating a loose center pin bushing. =
This is a
good test, but it is neither definitive nor quantitative, right? Also, =
whether
a loose center shows up on this test depends in part on how smooth the =
rod is
as well as how loose a bushing is. </FONT></SPAN></DIV>

Steinway is
doing in addition to friction measurement: measuring the amount of
