Damper tray flange screw

[David Chadwick]

Thank you Dave. I'll try to get something from Kawai or S&S/Boston first. If I come up empty I'd like to get a copy of your technical bulletin. I can think of several other pianos in my care that need attention to this area.

  Hi David,

  I got some technical info from Kawai awhile back.  They have a little kit with a technical bulletin attached for replacing the damper flange blocks.  I suspect it's the same as on your Boston.  In it is the information you will need to gain access to the necessary screws, as well as information on replacing the blocks, flanges, and pedal system adjustments.

  I can copy it for you and send it along, or you can see if you can get a similar bulletin from Boston.

  Let me know if you'd like me to send you a copy.  I was unable to compress the file to a small enough size to make it practical to send via e-mail, but I might be able to figure out how to fax the thing, or snail mail it if necessary.

  Does anyone have a special tool or trick to tighten the flange screw that the damper tray is mounted to? (see photo) The piano is a Boston GP-156 about 3 years old. The complaint was that the notes were in continuous sustain mode. I operated the pedal and heard many little clicking noises. Upon inspection all of the underlever flanges were just about ready to fall out. Every screw in the piano was loose. It was stored in a garage for several months while the client was building their home and out here in Las Vegas it is usually a death sentence in the summer months as it drastically dries out any moisture content that the wood might have and shrinking away from the fasteners.

  It looks impossible to get any kind of a tool on the screw head without removing the entire underlever system..... or maybe I'm missing something obvious. Any help will be greatly appreciated.
