When bedding the keyframe, try working from the second stud from the base, 
rather than from the end.  Then when the others are set, go back and do the 
bass.

Also, on a number of instruments, the keyframe has a tendency to 
"float".  Stated differently, they are exceptionally sensitive to humidity 
changes.  If/as I notice this kind of behavior, I tend to set the bedding a 
bit more tightly than I otherwise might.

Along the same lines, many more modern instruments do not seem to want to 
get properly bedded unless this is done with the keys and stack in 
place.  I do not think that many people still try to use the 
newspaper-under-the-balance rail approach anymore.  It really is rather 
useless when the keyframes are so flexible.

Hope this is of some value.

Best.

Horace
