[CAUT] wayward hammer return springs

[G Cousins]

Alan,
I agree with "the Don's" analysis however check the area for any rogue sales type persons. 
Added comment: Be sure to check the tightness of the spring rail. Winter dryness could have caused some loose screws (Yes Don, like me.).  
Another possible (debatable) benefit of springing the butts and stringing the flanges.

Good 
question, Alan.  It'll be fun to see what ideas crop up.  You didn't 
mention if you had serviced the piano before, so can attest to their having been 
in place at the last service.
 
Some 
guesses:
 
1. A pencil (or similar) was clumsily dropped inside and fell 
between the hammers and dampers.  The removal process dislodged springs. 
Not likely if this has the one-piece lid and front panel, of 
course.
2. 
Last person who worked on the action did not put the springs into the felt 
punching, but accidentally left them at the side of the punchings, on the 
wood.
3. 
Weak springs?  Maybe - but seems like they would not spring forward very 
far.
4. 
Mouse in action - other evidence would make this apparent, 
methinks
5. 
Evil spirits.
 
In 
any case, it is obvious that this client needs to buy a new Kawai.

List, 


Does anybody out there have any idea how a hammer return spring could 
become dislodged from it's cloth-lined groove in the hammer butt?  About a 
dozen were poking out from between hammer shanks on a Baldwin Hamilton, and I 
haven't been able to offer the client an explanation as to how they became 
truant from doing their usual duty.


Thanks,


Alan Eder
