<div>The noisy action might be overly hard knuckles, and possibly backrail felt. </div>
<div> </div>
<div>The bobbling hammers could be let-off/rep spring/blow/checking regulation having changed due to climatic changes.</div>

<div>Hope this helps.<SPAN contentEditable=false style="DISPLAY: inline-block"></SPAN></div>

<div class=AOLPlainTextBody id=AOLMsgPart_0_879f88c0-998d-401b-b686-1b014f970cb4>I am trying to solve a couple of problems on a Schimmel CC208 (6'10"). <br>
The piano is about 8 years old and is used by a teacher who teaches <br>
very talented, advanced students. 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>
