class=968171017-11062007>In most grand pianos the centerline of the keys are
perpendicular to the front of the keybed. Then, just behind the headscale, they
angle off -- flare -- to one side or the other so they end up in line with the
various capstans. Just before the capstan line the angle back again so that the
key c/l is once more perpendicular to the front of the keyframe.

class=968171017-11062007>In some pianos the action components (hammershanks,
wippens, etc.) are not perpendicular to their respective action rails. (Certain
Chickerings come to mind.) In these cases the keys generally do not have that
second angle. </SPAN></FONT></DIV>

action design using Renner wippens and hammershanks. For these to be mounted in
the conventional manner -- i.e., with their c/l's perpendicular to the action
rails -- new keys were required. </SPAN></FONT></DIV>

class=968171017-11062007>You start from the hammer strikeline and work down. The
hammer strike centers are transferred to the new action rails. Action brackets
are located and fitted. Action parts are mounted and aligned to the strings. The
hammer strike centers also become the capstan centers once an appropriate action
ratio has been developed. From here a keyset and appropriate keyframe is drawn
out using the original headscale spacing and the new capstan line and a new set
of keys and keyframe are made. In this case the drawing went to Rick Wheeler
(Roseland Piano) who made the keyset and keyframe. </SPAN></FONT></DIV>
