Nope. Had nothing to do with backchecks. Dragging backchecks do so on hard blows. This one worked on hard blows. ddf Delwin D Fandrich Piano Design & Fabrication 6939 Foothill Court SW, Olympia, Washington 98512 USA Phone 360.515.0119 - Cell 360.388.6525 <mailto:del at fandrichpiano.com> del at fandrichpiano.com - <mailto:ddfandrich at gmail.com> ddfandrich at gmail.com From: pianotech-bounces at ptg.org [mailto:pianotech-bounces at ptg.org] On Behalf Of David Love Sent: Saturday, July 16, 2011 7:15 AM To: pianotech at ptg.org Subject: Re: [pianotech] Weekend puzzler Backcheck bent too vertical or the tail of the hammers weren't arced. David Love www.davidlovepianos.com From: pianotech-bounces at ptg.org [mailto:pianotech-bounces at ptg.org] On Behalf Of Delwin D Fandrich Sent: Friday, July 15, 2011 11:09 PM To: pianotech at ptg.org 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 <mailto:del at fandrichpiano.com> - ddfandrich at gmail.com -------------- next part -------------- An HTML attachment was scrubbed...
