<DIV><FONT face=Arial>How often is too often to tune a piano? I =

<DIV><BR></DIV>Hi<BR><BR>I'm guessing the English action refered too =
is more
or less similar to the following diagram.<BR><BR>As you can see, the =
key has
to pretty much make it back up on its own. There is a repetition =
spring
to bring back the jack however, and if the hammer is checked high =
enough and
the return spring is strong enough it is possible to get the jack =
under the
knuckle quite quickly, aiding in the return of the key. That =
said, the
key has to be friction free enough and weighted appropriatly. It =
simply has to
get moving on its own.<BR><BR>Not much you can do except regulate =
checking as
high as you can get away with, get rid of excess friction, and make =
sure you
have enough weight back of the balance rail pin.

would be
easy enough to place <BR>a weight on the end of the key and see what =
happens.
