The hole in the keybed is is about a 1= inch hole (forstner bit again). The archives has lots of stuff= on this... David I. Original message From: Barbara Richmond To: Pianotech Received: Mon, 16 May 2005 16:12:33 -0500 Subject: Damper pitman Hi list, If you ever want to find out how much changes in the field of= piano technology, just take a nice long leave. When you come= back you will find that some things which were very= "fashionable" have gone by the wayside, or worse, find out that= a one time favored method or whatever is actually considered= harmful. (Sort of makes me think of a very funny scene in Woody= Allen's film, Sleeper.) Anyway, speaking of damper systems and trapwork--when I first= started in the business, I was told by John Ford (!), to remove= the pitman, drill a little hole in the end to insert a center= pin (a small bit of the sharp side protruding). This would keep= the pitman in place and eliminate noise. Since I've come back= to work, I've read that folks make the hole in the keybed= larger. So, is it a toss up, or did I horribly damage all those= pianos where I inserted the center pin? Anxiously awaiting enlightenment! :-) Barbara Richmond ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
