Just a slight hint of chucking and the key will = clatter.=20 I have never heard "noise from the balance rail/ hole/pin" ..caused = by the back check wire! If you hear "chucking" consider easing the keys = slightly at the balance rail. Slightly flexible and the check helps to absorb that noise energy. I = think Wim mentioned, better checking from thicker wire. Flexible, in any type of playing, will cause ""uneven check"". Wim is = correct imho! This is not so. The slight flexibility helps trap the tail. Like = all things in piano work there is a window for the parameter. There is always a window, in tuning..and voicing. A very..very..very = small window when it involves regulation. Too flexible unstable regulation, too stiff, then too much noise.=20 Yes to the first part. Too stiff, in my experiance..great check. The = noise?? Back to the balance rail. Tell me the relationship between the = back check wire and the "uneased key at the balance rail" I would love = to learn! Checking is more of a function of leather/felt quality, and tail = geometry, plus a little flex. <G> Correct....but...you fill in the blanks. =20 Definitely going back to sleep. Sleep well my friend.
