/let-off button position

[Barbara Richmond]

Thanks.  Silly me, I was looking at those broken jacks wondering if there was a way/angle the toe was connecting that made them more vulnerable and break.  Duh--if there's a screwball way of looking at things, I'll come up with it.  :-)

On to the next bit.  With the new jacks, I need to use the longer screws for the let-off buttons and route out bits of the rail to move it forward (towards the front of the piano).  There's plenty of room between the old buttons now, so there is room for the larger diamater buttons.  Why have the buttons gotten bigger--is bigger better for some reason?  Or is it simply that there's more fudge room, or bigger is easier to produce, or something else?

Thanks,

Barbara

  Hi Barb,
                  In a perfect world in the centre.  The Crescendo let off punching's from Jurgen has less sliding friction, and are a nice and firm, and still resilient.  They make let off very reproducible and consistent.

    Ha! I went downstairs to have another look and the poofy punching of the one new jack I installed; it had compressed nicely in however many hours it's been.  <Never mind>   :-)
     
    OK, a question about let-off buttons.  Does it make any difference where the jack tender/toe hits the button?  Is there an ideal place?
