[pianotech] agraffe leveling

agraffe levelingJoe,
Dampers are in newcondition. Actually not the damping that is the problem, but the out-of-phase strings caused by the poor mating of hammers to strings. If the strings just cannot be leveled by lifting, how much can you file a hammer before it causes another problem?

  Hi Scott,
  Could have someone trimmed these dampers to eliminate whoosh?

    I have a Samick like that. I have never gotten the bi-chords properly leveled. So just how much angle can you put on a hammer face without upsetting something else?

      I was attempting to level the strings on a newer Yam C6 the other day.   According to Goss's leveling device, all the tenor agraffes were way off.   I tried pulling up the left string to level but couldn't make enough of a difference.   A bad batch of agraffe drilling?   I guess in this situation you have to fit the hammer to what you've got?
