I have thought that there might be metal fatigue in the backcheck wire, that it might be close to breaking. Now I suspect that the wire is just moving in the enlarged hole in the ... doublet. Others, pleas comment. Thank you, John Baird </BLOCKQUOTE> I have also had back check wires bend very easy. However, I don't think the wire was moving in the doublet. (I figured out what it is, although I still have never heard of that piece of wood called that before). I also don't think it was wire fatigue. I just think it is a weaker wire material. Why Steinway choose to use that I don't know. Wim </HTML>
