I just wanted to see if it would make it even better.<o:p></o:p> <o:p> </o:p> On a weak instrument I would recommend giving it a try. As you said, $155 is an affordable experiment with potential for great return. I bought a <st1:City w:st="on"><st1:place w:st="on">Hitachi</st1:place></st1:City> 12” flexible shaft tool ($20, I think) for my cordless drill to be able to drill in tight quarters as you will need to be doing. You have to buy drill bits that have the hex quick release base to use the flexible shaft tool as well. <o:p></o:p> <o:p> </o:p> Hope this helps.<o:p></o:p> <o:p> </o:p> Eric<o:p></o:p> <o:p> </o:p> <div> Eric Wolfley, RPT Head Piano Technician Cincinnati College-Conservatory of <st1:PlaceName w:st="on">Music</st1:PlaceName> <st1:PlaceType w:st="on">University</st1:PlaceType> of <st1:City w:st="on"><st1:place w:st="on">Cincinnati</st1:place></st1:City> <o:p></o:p> </div> <div> <div class=MsoNormal align=center style='margin-left:.5in;text-align:center'> <hr size=2 width="100%" align=center tabindex=-1> </div> From: caut-bounces@ptg.org [mailto:caut-bounces@ptg.org] On Behalf Of Porritt, David Sent: Wednesday, May 16, 2007 8:48 AM To: <st1:PersonName w:st="on">College and University Technicians</st1:PersonName> Subject: [CAUT] Killer half-octave<o:p></o:p> </div> <o:p> </o:p> Esteemed colleagues:<o:p></o:p> <o:p> </o:p> Our NY D, (1983) has developed – in the last year or so – a killer half-octave from about A#5 – E6.  I’ve added some mass to the bridge right under C6 and that helped a little but the problem remains.  I’ve been searching through the archives this morning checking for any further heroic measures I could take within the confines of my budget.  <o:p></o:p> <o:p> </o:p> What’s the general consensus of opinion about the “Treble Tone Resonator” that Pianotek sells?  While my current budget precludes a full remanufacturing I think I can manage the $155.00 for that!  However, I don’t want to spend even that  – nor expend the time installing it  – if it wouldn’t help.  <o:p></o:p> <o:p> </o:p> Any ideas, suggestions, experience with it etc.?????<o:p></o:p> <o:p> </o:p> dave<o:p></o:p> <o:p> </o:p> __________________________________<o:p></o:p> David M.
