It seems like I read something about this at one time. String (frames) plates seem to creep over time. Sometimes the tuning pins are crowded against the backs of the holes. Not all of this can be attributed to pinblock fatigue. While beginning teardown of a Steinway D for new bridge caps, I noticed this and also that the perimeter bolts leave an impression that seems to creep forward and out from under the bolts. Does anyone know of what might have been published/shared about this? I am thinking of shimming the front edge of the pinblock when I reinstall it to compensate for this, but I wanted to know what others have observed. If the piano is really old, it may be quite severe.

I was recently looking at an article on piano plates that discussed this issue , the purpose of the holes on plates etc. Will try to find it since it is an interesting topic.

My upright has several holes in the plate and I think they might be there to catch falling action pieces and keep them virtually unretrievable. Not sure what the purpose would be in a grand...

Piano plates are cast-iron and need to have cooling holes built into the design so the cast-iron cools slowly and evenly.
