A once-in-a lifetime-problem

[PIANOTECHNICIAN at aol.com]

I have a customer with a beautiful Sohmer console from the 1960's, a model  
34-96 I believe. He complained 
of an echo. When I got there I loosened the nut on  the damper pedal and it 
went away.
A few weeks later, he called me with the same problem. I was baffled. What  
could possibly be causing
the lost motion to DECREASE in a pedal? It's always the other way around.  
When I inspected the trap work closely, I found the answer. The heavy spring on  
which the trap lever pivots, shaped like a Sigma, that connects the trap  
lever to the piano's floor was slowly breaking from metal fatigue! And as it was  
coming apart, the top part of the spring was coming up from the bottom part 
of  the spring, thus pushing the pedal rod up, and lifting the dampers off the  
strings! Has anybody out there ever seen this problem?
