That's often the culprit.

The client is complaining about noisy keys on a new RX2 she purchased in October. When I try the piano I hear a loud leathery kind of squeak on just about every key. The first thing that comes to my mind is jack against knuckle kind of sound. I take the action out, lift the hammers out of the way and push up on the whippens by hand, the squeak is still there, so it's not the jacks and it's not the capstans. Everything looks properly aligned, nothing seems to be rubbing against anything but all the whippens squeak, some louder than other, but all 88 do. I decide to take one out to get a closer look. It looks normal, I wiggle the jack, the repetition lever, the flange, no problem. I screw it back on the rail and then the squeak is gone! So all I did then was loosen every single single flange screw a couple of turns and screwed them back in. And that took care of the problem. But I am still puzzled. Then back at the store I tried another RX-2 and sure enough, it squeaks too. Not as loud, not as distracting, you really have to listen for it, but it's there. I tried my trick with the flange screws on that one but it did not make any difference. Any comments, ideas?
