Steinway M Backcheck Problem

Steinway M Backcheck ProblemOK.......... back to the piano on Monday and check all of this out. 

This is one of the reasons I have a policy of bringing all pianos into the shop for action regulating or action rebuilding. IMHO it's the only way you can do the job 100%, 100% of the time! (In the meantime, I have my Baldwin SF-10 half strung waiting for me).

Many thanks for all the input. I'll report back when as soon as I find the answer.

  Also, check hammer tail length, I like to see a 1" tail.

    Al,

    I was referring to the height of the backcheck in the key.

    NY Steinway calls for the check angle to be 68 degrees to the key, and there should be a 1/16" or about a 2mm gap, between the top of the backcheck and the tail of the hammer when the hammer is AT let-off.  That is, 2mm before the hammer drops.

    If these things are correct, I'd see if I can get some samples to check properly while I'm sitting at the piano, pulling the action, adjusting, checking, repeating, ad infinitum.  I don't recall if you tried to set samples in the piano and then duplicated that on the bench, or if you were just setting checking at the bench......??

      Have 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.
