Ralph Stillwell, a member of our chapter had an extreme case of this = problem on a upright piano with an open pin block.

He then replaced the pins in = the new "thicker" pin block. This greatly reduced the angle between the = tunning pins and the string. Finally he glued a piece of veneer on the = back of the piano to cover the holes that came through the back side. He = said it solved the problem. When I called Ralph to get his permission to = submit this he said he thought hardwood plywood would be better than the = maple he used if you could find it.
