[CAUT] back check wires

[Roger Jolly]

Hi David,
                   The very rigid wire tends to create key noise, from the 
B/R hole/pin.  Just a slight hint of chucking and the key will 
clatter.   Slightly flexible and the check helps to absorb that noise 
energy.  I think Wim mentioned, better checking from thicker wire.   This 
is not so. The slight flexibility helps trap the tail.  Like all things in 
piano work there is a window for the parameter.   Too flexible unstable 
regulation, too stiff, then too much noise.   Checking is more of a 
function of  leather/felt quality, and tail geometry, plus a little flex.  <G>

Definitely going back to sleep.

Roger
