What = happens is when you change to lifting the damper when the hammer is, sa= y, 2/3 of the way to the string is that it is closer to let off and fee= ls more like a longer, contiguous bump, rather than two separate ones. = And as Dean noted, the fingers have more speed at the point where the = key contacts the underlever. Makes a big difference. You can always try it on your action model... I'll be doing the warranty tuning on the 1st piano I did this on--some = 6 months ago-- next week. I'll give a report, and am fully prepared to= go become Tech Flambe. Dave S. In a message dated 1/19/2006 1:42:11 P.M.

I can feel that . Actually, IMHO, an 1/8 th inch in damper lift timing can make a HUG= E difference in action feel especially with high ratio actions. Frank= ly it doesnt' concern me what Seiler might think but rather my clients.= There is a sweet spot for ,most pianos, & when setting this up I fi= nd it most often that spot to be at half travel when the key aciton cyc= le is at it's most efficient & friction free spot in movement Picking= up the damper prematurely can increase the feel of touch weight or hea= vy touch syndrome dramatically on some actions. I'm always looking fo= r the optimum sweet spot when setting up a custom balnced action so tha= t I don't inadvertantly sabatoge all that fiddlin & didlin I just went = thru to create a very fluid action feel. Regards DAle Erwin The damper timing I thought was determined by the manufacturer. When t= he key goes down it meets a couple of resistance points. One, the end = of the key contacting the damper lift lever (but who can feel that?) , = and two, the jack contacting the let off button. (which everybody can f= eel) Since the contact between the key and damper lift lever is what,= 1/8 inch leeway what difference does it really make? The most importa= nt consideration is that dampers lift as a unit as the damper pedal is = depressed so that =93half dampening=94 can be utilized. I can imagine asking any of the piano makers including Seiler who show = up for the National Convention where they prefer the key to hit the dam= per lever and why. ---ric www.pnotec.com Dave Stahl Dave Stahl Piano Service 650-224-3560 http://dstahlpiano.net/ ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
