<HTML>List, I was sitting on the floor(the tables were too small to fit an action) o= f a Chinese restaurant filling the hammers of an MX 80 Yamaha 42" console wh= en I noticed something I had never seen or noticed before:  the hammer = rest rail "felt" was actually foam rubber.  Well, the shanks do land so= ftly...:-) It made me wonder about the quality of materials in the rest of t= he piano.   Didn't have time to do a full inspection as I was hustling to get the pi= ano back together in a fairly dark environment before the restaurant opened(= made it with 5 minutes to spare).  Like most Yamahas that I've tuned, i= t had very few strings with false beats and the pins were consistent.  = But how long before it starts to self-destruct?  Especially since it is= a Disklavier and gets played at least 8 hours a day...
