Oops-
I meant to write backcheck, not damper....that happens more and more =
these days.  Anyway, it was a great class about backchecks.  And the =
action geometry is also very good. =20
You could maybe set up a bunch of backcheck problems that way.  And it =
would be cheaper to buy a Steinway action model (naive thought, there).  =

The thing about doing it with a full action is that you wouldn't be able =
to see it...which is the way these darling problems happen.  I guess you =
could throw a curtain over the action model.

    Hello, Horace, where've you been?

  Under a rock....



    Richard Davenport's damper class is very, very good.  It is mostly =
about installing new dampers properly.

  Hmmm - the class I was thinking about was one for which he had built a =
special action model with modified parts so that any number of variables =
could be achieved.  I think it was called: "What if?"...but, memory =
fails.


    What I'm imagining is an action that is rigged to have as many of =
the subtle frustrations (such as Wim's backcheck problems) as could be =
fitted into 88 keys.  The object would be to learn to diagnose quickly, =
mostly by touch, without pulling the stack.

  Richard's model was only one or two keys (I think). =20

  I like the idea of a full action, but wonder about the visibility of =
the parts/relationships.


    If anyone has a Steinway action about to be ditched, I would =
undertake the rigging!

  What? Throw away the Crown Jewel of Perfection of piano manufacture?  =
Get thee behind me!  Block my hammer!

  Still, the visual does have some degree of visceral appeal...

      Ed,


      Something on this order used to be a part of a class that Richard =
Davenport was teaching a few years back.  Perhaps he is still teaching =
it from time to time.

          to remove a sharp corner might make it work.


        I am going to look at the wire, to make sure it is tight in the =
key. I will also look at the nap of the buckskin. I have already sanded =
the bottom edge of the tail to remove the sharp edge.=20



          Are you making a laminated checklist of all these suggestions? =
  You could teach a=20
          class next year.   Or sell the list.  ;-)



        I am saving all the suggestions for future references. I don't =
know if I will have enough material to teach a full class, but maybe a =
mini class. As with all educational material, the information will be =
free for the asking. :)
