The bridge suffered from missing wood in nearly all of the chord groups. The pins slant toward the direction of the lateral force of the strings, and there is no reinforcement under the bridge on the inside...the bridge pins go through the top and that's IT. The missing wood would leave the pins free to move at the ends that show, pivoting at the point where they go through the top...gee, that wouldn't crack the top...would it? (And yes, it did.) Needless to say, I reinforced the area under the bridge before putting it back together.
