David,

Thanks for the reply.  Yes, the [piano has the spade screw supports for 
adjusting the jack-stop rail.  They seem a bit insecure, and are bent, so 
that when I turn them, they turn in an eliptical fashion.  I think I'll see 
if I can straighten them, then adjust the rail inward.  Taking it off would 
work, but that would be a major hassle.  Bending it the supports would work, 
too, which is what I think they did at the factory when they regulated it.  
That's probably why they make a funny rotation when they turn....:-{
