<DIV><BR>Regulating 3-4 samples is good practice on any regulation, =

most
players, so the first place to look is a blow that will require a dip =
of

jack and
the butt. The leather that the jack pushes on should be approximately
perpendicular to the jack, when at rest. That allows the jack to slip =

under
the butt, either the blow is longer than optimal for those parts, or =
the
hammers are too long. Either will force the butt back too far, =
creating a
"cavity" under the butt that won't let the jack by without too much =
lost
motion. The action will still work, but this is a clue that it is not =
