Hi folks. I was traveling the back action today of a little grand I am finishing up rebuilding. I do not seem to be able to fully understand the geometry of this little bugger. It seems that there is a rotational component to some of the damper levers. As viewed from the piano bench (if the action were in the piano) you are looking nearly straight down the long axis of the damper lever, and of course, the dampe wire block sits on top of the end of the damper lever. Upon raising the damper lift rail, one can observe some damper levers travelling a bit to the right or left. But what also occurrs on some notes is a twisting motion of the damper lever that results in the damper wire block tilting (leaning) off to the right or left as the damper lever is raised. I realize that the damper wire blocks will move right or left with damper levers that travel right or left, but I am talking about a twisting motion along the long axis of the damper lever. I can only imagine that this would put quite a strain on the damper wire - pushing it against the guide rail. Is this unusual? What would cause such a motion? How can it be corrected short of parts replacement? Thanks for any thoughts. Terry Farrell Piano Tuning & Service Tampa, Florida mfarrel2@tampabay.rr.com
