David Ilvedson, RPT Pacifica, California Original message From: Piannaman@aol.com To: pianotech@ptg.org Received: 1/12/2006 3:26:15 PM Subject: Upright let-off jig I'm sure someone's thought of this before, so forgive me if my idea is = unoriginal! For those of you who use Bill Spurlock's grand letoff jig, this should = sound familiar. Every upright has a built in let-off jig: the hammer = rail. Today I was playing with a Hallet-Davis (Pearl River version) th= at's about 3 years old. It needed let-off regulation in a bad way, so = I experimented with the hammer rest rail. On this particular piano, I = could push it far enough forward so the hammers were close to the strin= gs, even ON the strings. Some pianos won't allow for that much movemen= t, but this one did. I set a some samples for letoff, then pushed the rail forward to the po= int where those hammers would wink when I depressed the key. I blocked= the rail so it stayed there, then adjusted the let-off to make the ham= mers wink. Worked like a charm. Pianos that won't allow for such free motion of the hammer rail may req= uire something to clamp onto the rail for the shanks to rest on--the Sp= urlock jig comes immediately to mind. Hope this helps someone in some small way!
