Lim The only way for the damper guide rail to touch the strings is for the soundboard to expand. This is probably caused by the high humidity. There really isn't anything you can do, except put the piano in an air conditioned room. The pin block not being flush with the stretcher is probably a poor fitting job by the rebuilder. The repairs are not difficult if you are familiar with rebuilding, including soundboard replacement, but not worth it.

The owner relocated from NY to tropical Singapore(humid) last Sep 2011. It was fine then but now it has problems. 1. The strings (bass and treble) are touching on the damper guide rail. 2. The pinblock is not flush with the stretcher at the mid section. Is change of climate the culprit? Will the repair be difficult?
