Steinway M Backcheck Problem

[Willem Blees]

I had a similar problem with a D at the university. As John suggested, reshape and rough up the tails. Also check balancier pinning. But even when you've done all you can,?I have seen this problem on brand new Steinways. So apparently it's something Steinway allows to happen.

Subject: Steinway M Backcheck Problem



I am regulating a 10 year old Steinway M with all original action parts. I am having a problem with checking. The piano checks 100% on the bench, but no checking at all in the bass section and 85% OK in all other sections.? I have adjusted the angle on the backchecks with no success. Does anyone have any thoughts on what the problem my be and?a possible fix?
