if all screws,specifically Front ones are tight holding the Action
Stack..Good luck!!

The noisy action might be overly hard knuckles, and possibly backrail felt.


 

The bobbling hammers could be let-off/rep spring/blow/checking regulation
having changed due to climatic changes.

 

Hope this helps.

I am trying to solve a couple of problems on a Schimmel CC208 (6'10"). 
The piano is about 8 years old and is used by a teacher who teaches 
very talented, advanced students. When the keys (primarily C3-C6) are 
released there is a noticeable "wooden" noise. The action was 
regulated and key bushings replaced about 6 months ago. I suspect the 
wippen cushion is the source. Any opinions? 
 
The other problem with this piano is bouncing hammers in the 
mid-section. Some will even double-strike on a mf, staccato blow. 
The hammer pinning does not seem excessively loose. I did the "swing" 
test, but did not check with a gram gauge, and got 5-8 swings on 
several of the hammers. Any suggestions greatly appreciated!
