It would be lovely to be able to buy two or three different degrees of narrow/wide, all for the same piano. Steinway Ds need some extra narrow trichords for the bass wound trichords, completely different from the plain wire trichords above the break.  <div><span style="WHITE-SPACE: pre"></span>It's a little hard to know how to measure. Unless you have a lovely custom tool for the purpose. I can see inserting a wedge and marking and miking, but that would be off by a bit. Are the thicker strings as wide as the space (one could see which one fit tightly)? I'm thinking you need to have a standard way of measuring if you are wanting to get usable results.<br> <div> <div> <div style="WORD-WRAP: break-word"> <div><br>Regards,</div> <div>Fred Sturm</div> <div>University of New Mexico</div> <div><a href="mailto:fssturm@unm.edu" target="_blank">fssturm@unm.edu</a></div> <div><br></div></div></div><br> <div></div></div></div></div></blockquote></div><br>
