Everett upright

[James Dally]

Hi:  I just started work on an upright that has the sostenuto as you
describe.  It is complete except some of the tabs are loose or ready to
fall off.  If a picture will help you let me know.  Jim Dally

> On the old WNG upright actions that incorporated sostenuto, it works like
> this:
> 
> Each damper has a wire that extends in the  opposite direction of the wire
> that holds the damper head.  This wire is about 2 1/2 inches in length and
> has a tab on the end.  A rail parallel to the rod that actuates the
> dampers, and below that rod is attached to the action frame such that when
> the sostenuto pedal is depressed, this rail pivots out, away from the back
> of the action.  On this sostenuto rail are "flanges" for each damper, and
> each flange has a spring loaded tab that, when the sostenuto rail is
> rotated outward will intercept the tab on the back of the damper.  When a
> key is pressed, the tab on the back of the damper is rotated back away
from
> the action.  When the sostenuto pedal is pressed, the tabs on the
sostenuto
> rail are moved in position under the tabs of any dampers on any depressed
> keys.  Clear?

> Every part of this sostenuto mechanism except for the flanges on the
> sostenuto rail could be easily fabricated in a well equipped shop.  The

> find them, you would have to be one hell of a craftsman to make them.
