Changing the brass pins for a very smooth plated set would be a plus.</div> <div><br></div> <div>The Renner cloth is long lasting stuff. There's also some very good English felt available from Heckscher. I think Norbert Abel uses it for some of his parts. Heckscher's website can be found at;</div> <div><br></div> <div><font face="Lucida Grande" size="-3" color="#000000">http://www.heckscher.co.uk/</font></div> <div><br></div> <div>Ron O.</div> <div><br></div> <blockquote type="cite" cite><font face="Verdana">I've got a bunch of Yamaha C3s from cruise ships to do key bushings on. Many of these piano get fairly rough use 7 days per week (piano bar and all that). So we're searching for a better way. Some of these get worn out in a matter of several months.</font></blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite><font face="Verdana">We've considered leather bushings, but my understanding is that there can be a chemical reaction between the leather and the Yamaha brass key pins. I don't see that the supply houses offer plated/steel pins in the Yamaha size.</font></blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite><font face="Verdana">So maybe we need to use cloth key bushings. I heard from some that Renner has the most durable key bushing cloth. Any opinions on that?</font></blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite><font face="Verdana">What about lubrication on the cloth bushing material to minimize friction and increase longevity? Microfine Teflon powder? But doesn't that just sort of fall out quickly? What about some sort of graphite? A synthetic grease, maybe like VJ lube? Anyone ever try anything like that? Any other ideas (constructive)?</font></blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite><font face="Verdana">Maybe I should just stand in back of the piano player with a whip or a well proportioned maple 2 x 4?</font></blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite><font face="Verdana">Thanks.</font></blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite><font face="Verdana">Terry Farrell</font></blockquote> <div><br></div> <div><br></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>
