Steinway M Backcheck Problem

Steinway M Backcheck ProblemHave you double-checked (ha-ha) the backcheck height??

William, are you talking about the height of the backchecks in the key or the height that I'm setting them at to check? I have tried setting them higher and lower with not much improvement.

Is it possible your bench set-up is enough different than your piano that it is unreliable?  

It certainly seems to be with this piano. I have always use wedges to be sure the action is sitting properly on my bench as I did with this action. I am in the process of adding glides on the front of my regulating bench as in the Baldwin keybed. I will see if I can adjust them to try and duplicate the Steinway keybed. Still working on it.

  Al,

  Have you double-checked (ha-ha) the backcheck height??

  I'd guess your problem would lie in height or angle, given the age of the parts.  I wouldn't concern myself where the bend is to establish the angle as long as the angle is correct.  I also would caution against roughing the checks any more.  If they are soft and like new, they don't need it.

  Another possibility: have you tried setting checking in the piano first, on a few samples?  Is it possible your bench set-up is enough different than your piano that it is unreliable?  

  Good luck,
  William R. Monroe

    Thanks Jon, good info, I'll check the angle and measure the arc against the hammers I arc myself. I also brushed the buckskin. They are soft and like new, but I will try and rough them up a little with some sandpaper to see if that helps any.
