I disagree. This is not really a band aid repair. I remember first hearing about CA in pinbocks in the early 90's. Some of those pianos are still holding up just fine. The trick is to get enough material as deep as possible for best results. That's why I'm planning on using a heat lamp on my next job. I've even contemplated drilling a small hole through each pin bushing to facilitate penetration into the block. Done properly, I believe that this repair can be fairly permanent. CA glue is pretty tough stuff. I doubt that it will break down significantly over time. Its basically acrylic plastic, right? The treatment may outlast the rest of the piano.
