The keys seemed normal without the use of the sustain. I also remember this happening in other pianos. What causes this and what is the fix? Thanks, Jere Fryett PTG Associate >> Most likely the wippen flanges are sluggish. It could also be tight key bushings. First try easing the keys. If that doesn't solve the problem, pull the action, and do something to free up the wippen flanges. There are several things that can be done. 1. Use Protec or other lubricant to lubricate the center pins. Put he action on it's side, and drop the lubricant on each flange. Repeat with the action turned on its other end. 2. Clean out the bushing cloth. I do this by taking a center pin remover, and carefully pushing the center pin out of the flange so that the other side is just barely free of the flange. Ream out the open side. Push the center pin back, and do the other side. In addition to reaming the bushing cloth, you might want to also put a drop of Protec in the hole. 3. Repin all the wippens flanges. 4. Rebsuh and repin all the wippen flanges. Before you go to that trouble, I would seriously consider replacing all the flanges. You don't think it was going to be easy, did you? Good luck Willem
