I've been caught a couple of times on this one. Just a slow learner I guess. <G> Before the sand paper comes out, I have a little key bed check list. 1. Lever clearance. 2. Spring condition and security. Also smooth action sides. 3. Bass stop block and hammer position. 4. Dag/frame wear. Use a few layers of masking tape on the top of the frame to check this. If the graphite on the frame is worn through or not worn at all, this will be a clue 5. Keybed/frame cleanliness. Once had a paper clip half imbedded into the rear rail of a Yamaha that gave me some grief. 6. Check the bed for straightness with a 48" straight edge.This can yield some clues for what you have to deal with. 7. Check that no frame/action stack screws are protruding. 8. Finally, back out all glide bolts before starting. Suprising how many pianos clean up the front and back rail when doing this. And then I usually find a tapered key height. You can be caught out very easily with key frames, the 'knock or bow' is not always the cause of the problem, just the symptom. Moral of the story: Look before you leap.
