List; I found numerous sticking dampers when new pianos (name omitted) were brought to the (DRY!!! in the winter season) college that I worked at. Some were tight guide rails, tight bushing flanges or missalignment of the damper wire to the guide rail. For the tight guide rails I had to remove the damper and ream some of the guide rail bushings as the easer would not work, For the dampers that were out of alignment it was simply a matter of realignment, but for the many tight flanges, I treated them with a water and alcohol solution (50 50). I only had to repin 1 to 2% of the flanges that did not respond to the treatment. In an earlier post I do believe the wood and felt shrinks and will become loose but if it shrinks past a certian point the hole will become smaller causing stickyness. I have also found the same to be true in other action centers. This of course is totally different from New Orleans Humidity. Regards; Ray hopland
