[CAUT] Action Rail Flange Cloth

[rwest1 at unl.edu]

Paul,

One thing that didn't get mentioned is the possible cushioning effect  
the cloth might provide.  I've always thought the cloth allows the  
flange to breathe a little bit with the changes in humidity.  The  
flange stays in position, but isn't damaged by the squeeze between  
the screw and brass rail.  Sort of like what a flange bushing does.   
I can't prove any of this, except to say that Steinway left the cloth  
off for a few years, but the cloth is back now, whatever the reason.
