This removes minimal material, and seems to pack felt at the surface, at least in my experience. Gives a subtle bit more "zing." Paddle or strip (backed with tape).<DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>There's also ironing. Using the brass fixture in a thermostatically controlled soldering iron (IOW, the keybushing ironing/sizing system) gives controlled results. One can vary temperature, time, and pressure applied.</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>And then there is single needle deep probe in the shoulder. Straight toward the core, or perhaps angled a bit up toward the crown. Experiment, sometimes yes, sometimes no.</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>Something Terry Otake showed us at the Shigeru Kawai one week seminar was a deep, multi-needle push from shoulder up toward the crown, using the metal needle fixture sold by Pianoforte Supply and Renner (Page 3-7 Renner catalogue, #1430D), intended for upright hammers. This is short enough that you can use it with fairly long needles and more or less "scoop them" from mid to deep shoulder so that the needle heads fairly deeply in the direction of the crown (easier to show than describe). The visualized concept is that you are pushing interior felt upward. I have had success to some extent with this.</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>Oops, now re-reading your post I see it is an upright model. Well, I guess all but the last item apply, and the last item might work but only from the top, and no need for the special tool. A regular needle tool would work. The special tool is for doing it from the shank side on a grand, needed because there isn't much room. Can't get there on an upright unless you remove the whole butt assembly.<BR><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><DIV>Regards,</DIV><DIV>Fred Sturm</DIV><DIV>University of New Mexico</DIV><DIV><A href="mailto:fssturm@unm.edu">fssturm@unm.edu</A></DIV><DIV><BR class="khtml-block-placeholder"></DIV><BR class="Apple-interchange-newline"></SPAN></SPAN> </DIV><BR><DIV><DIV>On Jun 14, 2007, at 10:17 AM, <A href="mailto:reggaepass@aol.com">reggaepass@aol.com</A> wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Hi Lists,</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">A client with a two year old Yamaha U1F complains that the C5-B5 octave is not as bright as the rest of the piano.<SPAN class="Apple-converted-space"> </SPAN>I listenened, and proposed to voice down the surrounding octaves.<SPAN class="Apple-converted-space"> </SPAN>He wants me to brighten up the octave in question instead.<SPAN class="Apple-converted-space"> </SPAN>I've never had to make a Yamaha brighter before.<SPAN class="Apple-converted-space"> </SPAN>I would probably be inclined toward some slight of hand if not for the fact that he sits there and watches the entire time I am working on his piano.</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">I cannot imagine juicing Yamaha hammers.<SPAN class="Apple-converted-space"> </SPAN>Is there another way to go other than filing the hammers in the C5-B5 octave?</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Thanks,</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Alan Eder</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">________________________________________________________________________</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">AOL now offers free email to everyone.<SPAN class="Apple-converted-space"> </SPAN>Find out more about what's free from AOL at AOL.com.</DIV> </BLOCKQUOTE></DIV><BR></DIV></BODY></HTML>
