Greetings, 
   I have found it useless to bed the keyframe without also checking to see 
that all the cleats from the stack are also in contact with the keyframe, 
itself.  It is VERY common on soldered action stacks to have one or more of the 
"feet" up in the air.  If not shimmed or bent to touch, they interject a stress 
in the keyframe that makes it very sensitive to climate changes. 
    Also, a properly bedded keyframe stays in contact with the keybed when 
both una-corda and damper pedals are firmly depressed!
