Marc, While all these suggestions are possible (and especially helpful is Roger's suggestion that you bring in a qualified tech who is already adept at damper work), you might also consider whether the damper upstop rail is set too high. If the damper travels too far (especially on a hard blow), the damper lever travels further in its arc, causing the wire to bind on the guide wire bushing. Take a good look at your favorite grand regulation manual (Yamaha, Steinway, etc.) for proper specifications. And I hope to see you in Rochester in some of the damper and regulation classes!

<div>If you still haven't solved the damper problem, I learned that Y.C. damper wires often lean on one side of the damper bushing. The lower bend needs to be regulated so that the wire doesn't rub so hard on the bushing. This most often causes a problem in the treble section where there are no weights to pull the underlever down. Usually, the wire is rubbing on the left side of the hole. Adjust the wire by bending near the damper block, preferably at the lower bend. I learned this from Phil Glenn. YMMV.
