Tom Driscoll ----- Original Message ----- From: Delwin D Fandrich <mailto:del at fandrichpiano.com> To: pianotech at ptg.org Sent: Saturday, July 16, 2011 2:09 AM Subject: [pianotech] Weekend puzzler The piano is a 1928 Chickering Model M, Scale 141 (small concert size). The problem is this: As the key is depressed slowly—pianissimo—for the first millimeter or so the key and hammer move smoothly. Then something starts binding, it feels like something in the action is dragging, holding the key and action back. After forcing the key down another three or four millimeters action becomes free and everything operates normally. On a medium to hard blow there is good power and the problem is hardly noticeable but at pianissimo the action will hardly play. What is the problem and what caused it? ddf Delwin D Fandrich Piano Design & Fabrication 6939 Foothill Court SW, Olympia, Washington 98512 USA Phone 360.515.0119 — Cell 360.388.6525 del at fandrichpiano.com — ddfandrich at gmail.com -- Bruce Browning The Piano Tuner -------------- next part -------------- An HTML attachment was scrubbed...
