The eye shown below is the very version about which I held this reservation. This style of loop will tend to tighten like a noose on the hitch pin.</div> <div><br></div> <blockquote type="cite" cite align="center"><img src="cid:a06240810c1b2e6464221@[10.0.0.25].1.0"></blockquote> <blockquote type="cite" cite><br></blockquote> <div><br></div> <div>I posted the example below of the style of double looped eye that we use, a couple of days ago. As you can see this loop is centered on the axis of the back length wire. This is achieved by first bending the wire with a very tight bend (to the right, as you look at the image below), before forming the loop/s. In addition to centering the coil, eyes formed in this way will not tighten down onto the hitch pin (provided that the loop is a relatively close fit to the diameter of the hitch pin).</div> <div><br></div> <div>I conducted quite a few eye-making experiments, before coming up with a jig which allowed me to make consistent double loop eyes.</div> <div><br></div> <div align="center"><img src="cid:a06240810c1b2e6464221@[10.0.0.25].1.1"></div> <div><br></div> <div>Notice also that while the back scale wire segment will be raised slightly, reducing the downbearing relative to an English twisted eye, a double looped eye such as the one shown above won't reduce the downbearing any more than will the single looped eye.</div> <div><br></div> <div>I recall someone mentioning this as a problem with using the looped eye in pianos which were set up for English eyes. When building a piano from scratch, or when the bridges are being recapped or replaced this isn't a problem. But certainly, it should be given consideration when setting the downbearing on instruments where the original bridge is being retained without lowering the plate.</div> <div><br></div> <div>Hope that makes sense.</div> <div><br></div> <div>Ron O.</div> <x-sigsep><pre>-- </pre></x-sigsep> <div><font face="Times New Roman" size="+1" color="#0000FF"><b>OVERS PIANOS - SYDNEY</b></font></div> <div><font color="#000000"><i>   </i></font><font color="#0000FF"><i>Grand Piano Manufacturers</i></font><font color="#000000"><br> _______________________</font></div> <div><font size="-2" color="#000000"><br> </font><font color="#000000">Web http://overspianos.com.au</font></div> <div><font color="#000000">mailto:ron@overspianos.com.au<br> _______________________</font></div> </body> </html>
