    But even if the stretcher and keybed are level, isn't it possible 
that in some pianos, the whole plate could be mounted in the piano with 
a slight tilt, depending on how they determined its correct placement 
relative to the bridge for proper downbearing?   Maybe this would happen 
only in cheaper pianos -- I don't know, having never checked.  But the 
main thing is that the plane of the strings in each agraffe has to be 
parallel to the crowns of the hammers, and if the plate has any tilt to 
it, you'd end up pulling a left unison string up and pushing a right one 
down, or vice versa.  --David Nereson, RPT
