Est. time for Young Chang Brackets

[Jim Johnson]

The new brackets will sometimes be off a little bit in terms of left/right orientation.  If they are not perfect, the string grooves will not line up with the strings and the tone will suffer.  I usually plan on hammer shaping as well if the hammers are starting to get grooved.  If nobody has tried to regulate the action, things should fall back in place.  If someone regulated it after the brackets started to expand (fairly common if they don't understand the problem), you will have a fair amount of regulating to undo what they did.

  What is an average estimate of time to replace the grand action brackets on the Young Chang's? Can we simply unscrew the brackets and install new or is there more leveling to the keyframe prior to re-regulating everything? (Hey, maybe this will turn into another class at the convention!)

  Sure enough, I ran into a 1991 piano that someone did a full regulation on this one three years and things are already drifting!!!  I regulated another grand last summer with the same issues.

  Is the manufacturer  covering any of the labor involved on any of these issues due to the brackets?
  Thanks,
