Horace, Jim, et al, First, I don't do dampers. Second, when I am forced to do dampers at the piano (like when one doesn't work properly), if it's the bushing I use a brass rod the size of a treble mute wire, heat it and burnish the guide rail felt. Works great. In a pinch, I've even used the treble mute wire. Takes much longer but will work. I've never pushed the felt thru the guide rail hole since I started using this method, and I can't recall having to do a second repair on the same problem damper. Don't even have an umbrella tool anymore. (I blatantly stole this from Jim Harvey.) Gina Carter
