[pianotech] Damper Pedal

[Carlos Ralon]

One of the reasons these damper rod swings break is that the felt stop is missing under the sustain pedal and the pedal over pushes to the floorboard. Be sure you replace that hunk of stop material or it will do it again.  I always did the repair on site. After replacing the swing, take a sharp punch and punch around the area the swing meets the rod swedging it to the swing rod. As mentioned before, the hard part is getting to it.

  Mig welding works, too! You can build up a nice filet to really beef it up.

   

  It might be a two piece damper rod with a missing rubber pad between the tenor and bass sections.

  Sounds like one or two damper rod hangers have bent or broke.

  If so remove damper rod, and drill out broken hanger.

  Insert a suitable size nail, cut and bend to shape.

  I have used a mini torch and solder to hold in place, and it seemed to work. Mind you, it was on a snug fit.

  Brazing would be better.

          A client today had a Kimball console.  When I depressed the damper pedal, most of the dampers in the bass didn't budge, until the mid tenor when they barely started lifting, and then by the time you looked at the treble, they were away from the strings by an inch or more.  Is there some underlying issue here besides regulation?
