I Don't Think So !! Pratt-Reed Problem
By John A. Tuttle

Hi,

I rarely take issue with people. I simply let them stumble around in the dark but in this case I must speak out.

Adjusting the dip on an upright piano has absolutely NO effect on the regulation of the player action to the piano action. The two are totally separate. And as a matter of fact, most players are equipped with a key lock so the keys won't move at all while the player plays. With the exception of having the key capstan adjusted up so high that it lifts the hammers off the hammer rail, the lost motion adjustment at the key capstan can not effect the performance of the player mechanism

Furthermore, Larry said the piano hand played just fine.

You are correct regarding the fact that the pneumatic should raise the wippen ever so slightly above the point that the keys do.

There is one slight correction I need to make to the letter I wrote to Larry. The felt circles I spoke of were actually small rectangular blocks of red felt. Why red? I couldn't tell you but I saw it in my dreams last night. I just wish I could remember which maker it was that installed them.

Play nice and have a Great Day, John --------------------------------------------------------------------------- John A Tuttle "Self-Playing Pianos" E-mail:tuttleja@concentric.net 407 19th Avenue 908-840-8787 (leave message) Bricktown, NJ 08724 Rolls:1-800-870-8784 (leave order) "We Keep Your Music Rolling" http://www.concentric.net/~tuttleja/ ---------------------------------------------------------------------------
