I doubt the rest will never be addressed, but I'd still like an answer to this one. If I ever get it, we'll try the next. If the crowned bridge supports soundboard crown, as you said, why do so many Steinways (with crowned bridges) have negative soundboard crowns before they even get out of the showroom? There is a fundamental contradiction here I'm trying to get you to answer to.</div> <div><br></div> <div>I also would like to know, how a long bridge supports sound board crown?</div> <div><br></div> <blockquote type="cite" cite>I will continue to try and help those with less experience than I by offering input.

I think there are others on this list that may be interested in discussing piano rebuilding issues from a point of view other than piano re-engineering.</blockquote> <div><br></div> <div>to which Ron N replied;</div> <div><br></div> <div>Again, I'm not discussing re-engineering. I asked for an explanation of a claim you made. It's very simple.</div> <div><br></div> <div>Agreed Ron, but nevertheless John, there is nothing wrong with re-engineering a piano if you;</div> <div><br></div> <div>a) have the skills and knowledge to carry it through and</div> <div><br></div> <div>b) if the resultant piano warrants to the effort required.</div> <div><br></div> <blockquote type="cite" cite>For the most part replicating their design and implementing many of the original techniques leads directly to better results and improved efficiency.</blockquote> <div><br></div> <div>That just depends on the understanding and knowledge of the rebuilder. On the other hand, replicating the original techniques could be a complete waste of time and effort. Everything should be reconsidered. If the original idea is good lets do it, if there are better ways of obtaining equal or better results lets dump the old idea.</div> <div><br></div> <blockquote type="cite" cite>I know through the phone calls I get and questions at chapter meetings I attend that there are many technicians just starting out or at an intermediate level that are interested in these basics of piano re-building.</blockquote> <div><br></div> <div>Of course. We all start out interested in the basics, which hopefully will lead to a pursuit of further knowledge, over an above the understanding of our forebears.  To recreate something in its original form, just as it was<font color="#0000FF"> (warts and all)</font>, would seem to be nothing short of a wasted opportunity.</div> <div><br></div> <div>I would like to add in conclusion that, like Ron Nossaman, I have found the bridges do not need to be 'crowned' to follow the contour of a crowned sound board. Sure the long bridge will rotate backwards on its axis<font color="#0000FF"> (from end to end)</font> just slightly to accommodate the crown of the board, but it will be so minimal as to be insignificant. The rib profile,  'stress in extreme fibre' and paring profile is where its at!</div> <div><br></div> <div>Ron O.</div> <x-sigsep><pre>-- </pre></x-sigsep> <div>_______________________<br> <br> OVERS PIANOS - SYDNEY<br> Grand Piano Manufacturers<br> <br> Web: http://overspianos.com.au<br> mailto:info@overspianos.com.au<br> _______________________</div> </body> </html>
