Marcel Carey, RPT Sherbrooke, QC -----Original Message----- From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org]On Behalf Of Piannaman@aol.com Sent: September 3, 2005 9:14 AM To: pianotech@ptg.org Subject: sticking note puzzler Actually, the real puzzler here is why anyone would conceive and build these pianos in the first place. A Nordheimer, made in the USSR before the wall came down in '89. Calling this a PSO is being too kind. What surprised me in the end was that the problem was really not related to the quality--or lack thereof--of the questionable piano in question. It really could have happened on any piano, though this was my first sighting of this particular problem. Symptoms: Key plays fine, then suddenly not. Examination reveals excess lost motion--not between the jack and hammer butt, rather between the capstan and the wippen heel. What it wasn't: tight center action parts rubbing together (my first suspect, and what I focused on for the first 20 minutes of my trip) Glue dropped on action parts anything to do with the key itself sharp edges on the jack rough material on the butt As I said, it was a new one on me. A simple, but unexpected problem. I'll post the answer tomorrow if there are no correct guesses. Dave Stahl ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
