<DIV><FONT face=Arial color=#000000>My name is Rex Burrus from Chicago a=
nd I'm
new to the list and recently new to piano technology having been indoctrinat=
ed
by classes of a local mentor and taken under the wings of the Chicago PTG
chapter early in 2005. I've been tuning mainly, but also work the
technology angle of pianos, plus work on players for all of one year

<DIV><FONT face=Arial color=#000000>I have on two occasions come to wond=
er about
action mounting in an upright. In both cases, I have found the action =
to
be somewhat ajar and not even settled upon the mounting pins in the keybed w=
hich
have made these pianos play lousy. The one piano was completely cured
simply by repositioning the action properly and the customer was so overjoye=
d
that I made extra money on that tuning. On my current project, I found=
that the action is not properly resting on all the mounting pins. In f=
act
the middle two pins are not even in contact with the wells in the action
supports. These pins are threaded and squared so that turning them mov=
es
the mounting pins up and down in the keybed. I suspect that at another=
time, some "tooner" ran into trouble seating the action and at a minimum rai=
sed
the treble end as the treble hammers were striking the v-bar and making no
sound. So, minimally, I'll lower the far upper mounting pin and this
should cause all mountings to fall into proper alignment. Intellectual=
ly,
I'm wondering overall what any procedure might be to precisely locate an act=
ion
using these mounting pins. I understand that raising or lowering the
action changes the striking point of the hammers on the speaking length of t=
he
wires, so I'm curious as to how the striking point is found or if there are =
any
good references on this, and what might be a proper procedure for adjusting
(regulating?) the mounting pins in the keybed of an upright? Is this a=
factory only adjustment?</FONT></DIV>
