The 1/2" dowel with a 3/4 = inch punching glued to each end and fitting into a 3/4 inch recess = (forstner bit) eliminates that remaining friction. The hole in the = keybed is is about a 1 inch hole (forstner bit again). The archives = has lots of stuff on this...

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?=20 Anxiously awaiting enlightenment! :-) Barbara Richmond ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
