<HTML><HTML>List Turns out that the problem wasn't one single glaring mistake, but rather a c= ombination of little things  that added up to less than satisfying res= ults.  Went back yesterday to find that the after-ring had diminished, somewhat.&nb= sp; As I suspected/hoped, the damper felts seated themselves to the strings= on their own over the course of the week.  There was still some after= -ringing, though, so I set about to check a few of the things that were sugg= ested to me. 1. There was some ringing of the non-speaking portions of the bass strings, = so I muted them with felt. 2. There were two bass dampers that had become glued together, and thus were= not damping their strings as effectively as they should, resulting in a hig= h overtone-y ring. 3. There was one tenor bichord damper that wasn't centered well enough, leav= ing the right string to create some after-ring. 4. But the biggest improvement came after I did something that no one sugges= ted, other than myself when I subtitled my post "probably just stupidity on = my part": I hadn't tightened the action bracket screws into the plate quite = all the way!  The screws were hand-tight, but I was able to force the = bracket closer to the plate with a little hammering and I found I could put = another turn or TWO into the right action bracket.  Although this brac= ket was farthest from the dampers, it did make a difference. I'll have to file this one under: D'oh! BTW, the customer was satisfied with the new dampers even before I made any = improvements.  Now, however, I, am satisfied with the results and woul= d like to thank everone who contributed.  Tom Sivak Chicago PTG Associate </HTML>
