[pianotech] Soft-fall mechanism

[Paul McCloud]

These are made by QRS.  You can detach the cord from beneath the piano.  There is a small sleeve, much like on an upright damper block, with a setscrew you can loosen.  THe setscrew holds the end of the cord.  The cord/wire is then pulled out of the small bellows arm.  You can then remove the fallboard.   To install, just reverse the procedure.  It's a little tricky to thread the cord down between the keys and through that hole.  Thread the cord thru the bellows arm and secure with the setscrew and sleeve.  
I've installed a bunch of these.  I had a lot of callbacks where the screw eye came out of the fallboard and it stopped working.

Serviced a two year old Boston grand today and needed to pull the action to find out why b5 and c6 keys were binding. In the attempt to remove the fallboard, I found what looked like a plastic coated wire attached to the rear of the fallboard.  The attached wire ran down between two keys, through a hole in the keybed, and hooked onto a mechanism underneath the piano that operated in such fashion as to produce a slow fall of the fallboard.

Has anyone on this list had any experience with this type of mechanism?  If so, who might be a distributor? Better yet, who might be the manufacturer.  I need to know how to go about detaching the wire in order to pull the action without damaging the mechanism.
