Take one hammer near the middle of the piano and turn down the drop screw as far as it will go. Next, set the let-off on that note. Now re-set the drop. I've had this situation before and this was the solution. Now do the rest of the regulation steps.

These are new hammers shanks & flanges, but I didn't hang them. I had previously shaped the tails On the first four notes in the treble, I roughed the tails, filed down the edges of the tail, and reset the back checks, making the rake more "flat," I also allowed the hammer to check lower and reduced the rep spring. That helped some, but not enough. I looked at some of the other suggestions, but none really seem to apply. Out of the piano, the action behaves perfectly. But once it is in the piano the bobbling problem doesn't go away. Finally I took some measurements, and maybe this is the problem. What is supposed to be the distance from the center pin to the end of the hammer? Here is what I found. note 1 5 1/4 note 26 5 1/8 note 27 5 3/16 note 41 5 1/4 note 54 5 7/32 note 55 5 9/32 note 72 5 1/4 (As I said, I didn't hang these hammers, and neither did Steinway) Can any one tell me if these measurements are related to the problem?
