I find the most stable results from bedding the keyframe without keys or stack on it, then placing the stack on there and making sure that all the "feet" are sitting evenly on the cleats. This way, there is no tendency of the metal stack to warp the wooden keyframe. With everything relaxed, I use shims under the stack's feet to fit it to the keyframe. If the stack doesn't sit evenly on all its feet and you go ahead and screw it down, then bed the keyframe, it will leave a stress in the keyframe that will cause it to move when the weather changes,(since the wood doesn't react like the metal, particularly in the Steinways). If you keep the action's foundation relaxed from the bottom up, this problem is greatly reduced. Regards, Ed Foote RPT
