Talk to Jack Wyatt in Garland, TX. He did a tech at our September chapter meeting called "Turbocharging the Upright" that deals with doing just that: adjusting the position of the action so that you can get repetition out of it. It basically involves tilting the action forward which changes the plane of contact between the jack and the butt. This will obviously require compensating lost motion, dip, etc.; and finally bending the action bracket to compensate for change in down weight. (I'm relying on my memory here). Two things I recall Jack emphasizing very strongly regarding this procedure: 1) It is an advanced procedure not to be attempted by beginners (like me). 2) Charge a lot of money for it, because it adds considerable value to the piano. Give Jack a call at 972-278-9312 for details. ======================================================================= Benjamin Treuhaft wrote: > > My customer wants to repeat notes on an upright without coming all > the way up with the key, in fast playing.
