Yo Roger, Thanks for the tips on procedure. In my experience, I have very rarely found one well bedded from the factory (that being the source of my wisecrack to Vince). His observation about noise is, I think, well taken - not because it is impossible to do a good bedding job with the design, but because the design means that humidity fluctuations in either direction will cause knocks to appear. Dry will make them appear anywhere (and I think maybe exacerbated by springiness in the areas between glides, leading to more of a bounce effect than when the rail is solidly mated to the bed), wet in the middle due to bowing caused by the fulcrum effect of the outer glides. It does have the virtue of being easy to fix/adjust. Of course, the Steinway design also has seasonal knocks, at the outer ranges. I find the least noise problem with those like Yamaha and Kawai that just bed the rail flat and do it well. Regardless of design, somebody has to keep after the piano, which, as Mr. Jolly will be the first to point out, means job security.
