I wrote down notes on all your suggestions, shouldered my big tool case, an= d went downstairs to do battle with the D. I pulled the action and put it on a table and started checking. It bothered me a little that it took so much harder of a blow to make the note click on the bench than in the piano, but I figured this was due to some resonance thing going on. I couldn=B9t make i= t click by manually manipulating individual parts, like the jack or the rep lever, but it clicked real well when I struck the key. I couldn=B9t see the jack hitting anything, so I decided to remove the hammer and see what happened. No click. In looking at the flange, I noticed a small black lin= e on the underside of the nose of the flange. Aha! The jack was hitting the flange, and left a graphite mark! I replaced the hammer, and looked at it some more. For some reason, the tip of that flange was a little lower that its neighbors, as were some the other clicking notes. I didn=B9t want to mes= s with key dip, since I just barely had enough, so I played around with shimming the flange. I ended up putting some travel paper under the back side of the flange (opposite the drop screw) crossways, only on the vertica= l part of the very back part of the groove. I wish I could draw a picture! Any way, the result was to move the flange back, and raise the drop screw end as it rode up on the rail. Of course, this necessitated readjusting th= e capstan, letoff, and drop. After that, no more click on the bench! Almos= t home! The action goes back into the piano, and it clicks just like it did before. The work process is interrupted at this point by a short stream of unprintable comments. The action comes out, and I can=B9t make it click for love or money. Back in, and it clicks on a keystroke that=B9s barely mf. Okay, think now. It must be something in the piano that=B9s making the noise= . Dampers! Hold the damper up, play the note. No click. Aha again! Pull the action out, work the damper. No click. Work the damper really hard. No click. I notice that the dampers on the clicking notes travel up quite = a bit farther than their neighbors. Finally the light comes on. Earlier, in regulating the sostenuto, I had bent the bracket down to get the bar properly lined up with the tabs. It didn=B9t work at all before I started working on it during semester break, and it doesn=B9t work now. But the clic= k sure went away after I bent the bracket back up! The underlever was, of course, hitting the sostenuto bar. I don=B9t think I ever heard the jack hit the flange when the action was in the piano, and I=B9m not sure I ever played the notes hard enough to make it hit. It was a rather effective distracter= , though. Now I just hope the pianist for the Amadeus Trio won=B9t need the sostenuto Friday night. I don=B9t think it=B9s going to work until I replace the underlever action, and that=B9s not going to happen this week. Boy, I=B9m glad this is over.
