  Subject: strange action configuration in Sejung


  List,=20

  Today I was prepping a brand new Vivace piano, made in China by =
Sejung.  I regulated and aligned the capstans, and was about to regulate =
the let-off when I noticed something strange:  the jack-stop rail is =
directly above he eyelets for the regulating buttons.  There is NO room =
to get the regulating tool in there.  IN order to access the eyelets, =
I'll have to bend the jack-stop rail a fair amount.  What were they =
thinking:  that the let-off would be set for life?  =20

  Any ideas?  Is this a weird configuration or what?  =20

      Yes, that's exactly what they were thinking.  It's amazing how =
many things in pianos are designed with the underlying thought that "Our =
pianos are perfect; nobody'll ever need to adjust this or get a tool in =
here ."
      If the props for the jack stop rail turn easily, I would turn it =
in far enough to be able to regulate let-off.  If that prevents the =
jacks from coming far enough away from the butts, then try bending the =
rail up.  Do you have the type of eye-screw regulator that lets you turn =
the screws at an angle?  Or are they the spade type?
      It'd be a big hassle, but you could remove the jack stop rail, =
regulate let-off, then put it back. =20
