Thank you for the help.

I also have been surprised that the buzz is isolated in the bass strings =
and that all of the bass strings are producing a buzz.  The first thing =
I thought of was something loose on the soundboard, loose ribs etc but =
after numerous checks have just about decided it is the bass strings =
windings. When I twist the string or replaced a string there was a =
definite improvement but a buzz that sounds like loose winding is =
pronounced. I am thinking of ordering a couple of fresh strings just to =
see if that solves the problem.  I am going to do some more checking =
around the rim but I have yet to find where any  fork lift has come =
through the rim or any repair has been made.

  Can you describe the buzzing more.  I would be surprised if it were =
the strings.  Loose windings developing on all wound strings at the same =
time seems unlikely.  Have you checked the connection of the soundboard =
to the rim on the side that was impacted by the forklift?  Go underneath =
and push up around the edges with your thumbs and see if you hear any =
crackling or see any movement.  Use a thin feeler gauge to check for =
around the edges and the ribs as well.  Take a mirror and a flashlight =
and look around under the plate for some foreign object, check the bass =
bridge for delamination of the cap.  I'm sure there are other =
possibilities as well.

    Are there any piano techs on this list that are still interested in =
talking about piano problems or are we now just solving political =
problems.  If so, I could use your input.

    I am the servicing piano technician for a Hamburg Steinway (D) 9 =
foot grand. According to the serial (450690)number it seems to be a =
1977.=20

    I first came on the scene with this piano a couple of years ago and =
although everyone seems to be in love with the piano I immediately was =
taken back by a pronounced buzz in all of the 39 wound strings.  There =
seems to be plenty of bearing on the bass bridge. I have exhausted all =
of my known fixes. I have put additional twists in the strings in hopes =
of tightening the windings. I've tapped the strings down on the bridge =
and hitch pins. all of which improved the piano a bit.  There is a box =
of Mapes strings which I assume were kept for emergency replacement that =
have been boxed for 6-7 years. I replaced a few of the strings with the =
strings from the box.  This also improved the sound considerably  on =
those strings but a buzz is still quite audible.. From what I have =
heard, at the time of purchase, a fork lift had been run into the side =
of the piano and the church had made a special buy on the piano after =
the repair. I can'! t help but wonder if the mapes strings being rolled =
up in the original box wouldn't also have developed a few loose =
windings. I have heard some good reports about Arledge Bass Strings and =
am very interested in any experiences you have had with these strings.

    This piano is used for many concerts during season. I am surprised =
that we have had no complaints from the artists. Any help and =
suggestions will be greatly appreciated.
