<DIV><FONT face=Arial color=#000000>I have on two occasions come to=
wonder about action mounting in an upright. In both cases, I hav=
e found the action to be somewhat ajar and not even settled upon the mo=
unting pins in the keybed which have made these pianos play lousy. =
; The one piano was completely cured simply by repositioning the action=
properly and the customer was so overjoyed that I made extra money on =
that tuning. On my current project, I found that the action is no=
t properly resting on all the mounting pins. In fact the middle t=
wo pins are not even in contact with the wells in the action supports.&=
nbsp; These pins are threaded and squared so that turning them moves th=
e mounting pins up and down in the keybed. I suspect that at anot=
her time, some "tooner" ran into trouble seating the action and at a mi=
nimum raised the treble end as the treble hammers were striking the v-b=
ar and making no sound. So, minimally, I'll lower the far upper m=
ounting pin and this should cause all mountings to fall into proper ali=
gnment. Intellectually, I'm wondering overall what any procedure =
might be to precisely locate an action using these mounting pins. =
I understand that raising or lowering the action changes the striking =
point of the hammers on the speaking length of the wires, so I'm curiou=
s as to how the striking point is found or if there are any good refere=
nces on this, and what might be a proper procedure for adjusting (regul=
ating?) the mounting pins in the keybed of an upright? Is this a =
factory only adjustment?</FONT></DIV>
