[pianotech] Bridge pin locations help (image oops)

[David Love]

There are probably multiple causes for "falseness" depending on how you define it. Individual string anomalies, flag polling bridge pins, poor capo terminations or even bridge movement which is just out of phase with string movement (a theory Del suggested to me on one occasion). 

I don't think that an imprecise match between the bridge bevel and the center of the pin is a cause, at least not where the pin contact is to the speaking side of the bridge bevel (unless it's extreme and contributes to flag polling). There are just too many examples of pianos where this occurs that do not have that problem.

Roger,

With no offense intended, and with respect to my particular circumstance,
   I am hoping you are in error, and Ron is dead on target.

By the way: the event for Sunday has been canceled,
   so I shall have to wait until a bit later to determine the outcome.

Sincerely,

Keith

I've found that false beats can be reduced or eliminated by seating, on both new pianos out of the crate that don't have loose pins and strings on 90 year old pianos that obviously have loose pins. …
