<DIV> In traditional<BR>American actions there is no jack slap rail =

instead there is a felt<BR>cushion behind the balance hammer below the =

aperture.<BR><BR>Regards<BR>Alan Forsyth<BR>Edinburgh</DIV>

<DIV> I agree that most (American) actions, especially =
new
ones, do not have a jack stop rail, but I've seen them in many old
uprights. I think Yamaha may have used one in its U7 or some other =
model. In the actions that don't have the rail, they have felts on =
the
jacks or catchers or both, to prevent the jack from flying too wildly or =
far
away from the butt on certain types of blows. -- David =
