There isn’t going to be a lot of side load and you could reinforce the thin wall by soaking it with CA or epoxy. It also looks to me like you could scab on a thin piece of wood on a few of those keys enabling you to move the capstan a little bit more. Or without a lot of effort for a master woodsmith such as yourself, just cut 3-4 mm off one edge of the key and glue 3-4 mm on the side where you need more meat.<o:p></o:p></span></font></p> <p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size: 10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p> <div> <p class=MsoAutoSig><b><font size=6 color=navy face="Bradley Hand ITC"><span style='font-size:22.0pt;font-family:"Bradley Hand ITC";color:navy;font-weight: bold'>Dean</span></font></b><font color=navy><span style='color:navy'><o:p></o:p></span></font></p> <p class=MsoAutoSig style='margin:0in;margin-bottom:.0001pt'><u1:PERSONNAME u2:st="on"><font size=3 color=navy face="Times New Roman"><span style='font-size:12.0pt; color:navy'>Dean May</u1:PERSONNAME>             cell 812.239.3359 <o:p></o:p></span></font></p> <p class=MsoAutoSig style='margin:0in;margin-bottom:.0001pt'><font size=3 color=navy face="Times New Roman"><span style='font-size:12.0pt;color:navy'>PianoRebuilders.com   812.235.5272 <o:p></o:p></span></font></p> <p class=MsoPlainText><u1:PLACE u2:st="on"><u1:CITY u2:st="on"><st1:place w:st="on"><st1:City w:st="on"><font size=2 color=navy face="Courier New"><span style='font-size:10.0pt;color:navy'><u3:place u4:st="on"><u3:City u4:st="on">Terre Haute</span></font></st1:City><font color=navy><span style='color:navy'></u3:place></u1:CITY></u3:City> <u1:STATE u2:st="on"><st1:State u5:st="on"><st1:State w:st="on">IN</st1:State></u1:STATE></st1:State>  <u1:POSTALCODE u2:st="on"><st1:PostalCode u6:st="on"><st1:PostalCode w:st="on">47802</st1:PostalCode></u1:POSTALCODE></st1:PostalCode></span></font></st1:place></u1:PLACE><font color=navy><span style='color:navy'><o:p></o:p></span></font></p> </div> <p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size: 10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p> <div> <div class=MsoNormal align=center style='text-align:center'><font size=3 face="Times New Roman"><span style='font-size:12.0pt'> <hr size=2 width="100%" align=center tabindex=-1> </span></font></div> <p class=MsoNormal><b><font size=2 face=Tahoma><span style='font-size:10.0pt; font-family:Tahoma;font-weight:bold'>From:</span></font></b><font size=2 face=Tahoma><span style='font-size:10.0pt;font-family:Tahoma'> pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] <b><span style='font-weight:bold'>On Behalf Of </span></b>Farrell<br> <b><span style='font-weight:bold'>Sent:</span></b> Wednesday, May 14, 2008 8:43 PM<br> <b><span style='font-weight:bold'>To:</span></b> pianotech@ptg.org<br> <b><span style='font-weight:bold'>Subject:</span></b> Key-Capstan-Wippen Heel Alignment</span></font><o:p></o:p></p> </div> <p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size: 12.0pt'><o:p> </o:p></span></font></p> <div> <p class=MsoNormal><font size=3 face=Arial><span style='font-size:12.0pt; font-family:Arial'>Got an old action that I'm rebuilding (all new parts except keys, frame and rails).

This action needs to work very well. I'm thinking the best thing to do is to offset the capstan some amount (but not so much that the integrity of the capstan hole in the key is compromised - i.e., not too close to the key edge) and tolerate the capstan not being perfectly centered with the wippen (making sure the capstan isn't lifting its adjacent wippen, etc.). Appropriate compromise should not negatively impact action performance - correct? Or is there some sort of slick solution out there that I'm not aware of?</span></font><o:p></o:p></p> </div> <div> <p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size: 12.0pt'> <o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=3 face=Arial><span style='font-size:12.0pt; font-family:Arial'>Thanks.</span></font><o:p></o:p></p> </div> <div> <p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size: 12.0pt'> <o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=3 face=Arial><span style='font-size:12.0pt; font-family:Arial'>Terry Farrell<br> Farrell Piano</span></font><o:p></o:p></p> </div> <div> <p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size: 12.0pt'> <o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=3 face=Arial><span style='font-size:12.0pt; font-family:Arial'><a href="http://www.farrellpiano.com">www.farrellpiano.com</a><br> <a href="mailto:terry@farrellpiano.com">terry@farrellpiano.com</a></span></font><o:p></o:p></p> </div> </div> </body> </html>
