The new installation instructions are much improved over what we used to have. You should not ignore some of the "evil" suggestions, including Wapin, I would add channeling hammershanks right down to and through that section (personally I do the whole piano tapered by weight). This will stiffen the shank and also reduce the shank weight making the hammer more prominent (theory).  Also try changing hammer (strike)weight, up first of course and then down unless up works.</DIV> <DIV>Bob Grijalva recommends doing all your voicing tricks first then setting the resonator but I have had success doing some of each and back and forth. But for getting the sound out of the box and putting more air under the tone (improving carry) nothing has impressed me more than these devices. This provides the best foundation for balancing registers and adjusting brillance I have ever encountered short of a new well set Steinway board (I do find them once in a while).  I have had similar experiences to Eric W the more the piano "needs" the greater the result. You might even reasonably expect miracles in your situation.</DIV> <DIV> Chris Solliday</DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: black">From: <A title=dporritt@mail.smu.edu href="mailto:dporritt@mail.smu.edu">Porritt, David</A> </DIV> <DIV style="FONT: 10pt arial">To: <A title=caut@ptg.org href="mailto:caut@ptg.org">College and University Technicians</A> </DIV> <DIV style="FONT: 10pt arial">Sent: Wednesday, May 16, 2007 2:57 PM</DIV> <DIV style="FONT: 10pt arial">Subject: Re: [CAUT] Killer half-octave</DIV> <DIV> </DIV> <DIV class=Section1> Thanks for all the suggestions from my query this morning.  This is not a new problem, it’s just that it finally reached the dean’s desk.  The (relatively) small area that doesn’t project got worse (i.e. wider – more notes) in the winter and is now marginally better in the spring.  The piano needs rebuilding about a year before I’ll have enough budget to do it.  <o:p></o:p> <o:p> </o:p> I think I am going to order one of those treble resonators since I can try it at a modest cost.  The hammers are fairly new, Ronsen Wurzens that I can’t blame.  It is clearly a sounding board stiffness problem.  I just didn’t have any exposure to this particular “fix” so I wanted to see what experience others have had.  So far the reports are favorable.  <o:p></o:p> <o:p> </o:p> I’ll let you know if I get a miracle cure that would allow me to delay its rebuild even longer (I do have other problem pianos to address though not ones that are this public)!<o:p></o:p> <o:p> </o:p> dp<o:p></o:p> <o:p> </o:p> <DIV> David M.
