List, Several years ago, I worked for a piano dealer who had 2 used Steinways on the floor. Both had the accelerated action. Both had severe cases of pulley keys ( worn balance holes ). A rep from a good competitive company explained to me that Steinway has this problkem a lot because of the accelerated action. He then drew me a picture showing the curved felt punchings and explained that it was caused bacuase the keys rock in an arch rather than on a pivot point like a traditional action. Another good technician told me that this is false and that the Steinway is simply a different design and that both actions rock in an arch. Both technicians are well respected in the PTG at the highest levels and have names for themselves. Who is right? Ron Shiflet, RPT Phoenix Chapter
