Cool checking

[Stéphane Collin]

Hi Ric.

Yes, the device is checking under more soft playing than the usual 
arrangement, even with the repetition springs kind of hard limit regulated. 
The backchecks are at 68 °.  On this action, the only problem I had is that 
the regulation of the backcheck is not very continuous : I mean that just a 
little more higher checking is immediately too much, and a little lower is 
immediately way out.  But just right is curiously evenly just right through 
all the scale.
Like you, I never ran across another example.  It sounds to me like a very 
good idea, and after all not that expensive to implement.  Anyone thinking 
about possible drawback ?  Obviously, even the durability is far superior.

Best regards.

Stéphane Collin.

Hei Stéphane

I cant say that I have run into this arrangement before and I'd be very
curious to hear if anyone else has and what their experience with it
is.  You say the thing checks not only quietly but solidly under all
levels of play ?

    Hi Ric.

    Here is a pic of that Rönish checking arrangement.  The piano is
    from the 1920 and I have no reason to believe that what you see is
    not original.  Yet, see the condition of the leather !  And this is
    in the tenor section, where you usually have the parts worn out.
    And the noise to catch strength ratio is the best I have ran across.

    Curiously enough, the rest of the piano is kind of cheap.

    Best regards.
