When the keys (primarily C3-C6) are <br> released there is a noticeable "wooden" noise. The action was <br> regulated and key bushings replaced about 6 months ago. I suspect the <br> wippen cushion is the source. Any opinions? <br>  <br> The other problem with this piano is bouncing hammers in the <br> mid-section. Some will even double-strike on a mf, staccato blow. <br> The hammer pinning does not seem excessively loose. I did the "swing" <br> test, but did not check with a gram gauge, and got 5-8 swings on <br> several of the hammers. Any suggestions greatly appreciated! <br>  <br> Richard Capp <o:p></o:p></span></font></p> </div> <div> <div class=MsoNormal align=center style='margin-top:7.5pt;text-align:center'><font size=3 face="Times New Roman"><span style='font-size:12.0pt'> <hr size=2 width="100%" align=center> </span></font></div> <p class=MsoNormal style='margin-top:7.5pt'><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>AOL now offers free email to everyone.
