>>Typically CA makes an instrument tunable again, sometimes makes pins actually tight again, but not in the "Brand-New Baldwin" category. I've seen it happen when too much CA is used. AS Thump said earlier, CA will continue to cure over several days. It needs moisture to cure, and if you use a lot of it, it will take awhile for it to happen. I would not recommend putting more than 2 oz on a piano. You should know where the section with loose pins is and give it a little more than the rest of the piano. There may a handful of pins that need additional treatment after a few days, or the next time you come out. Give them a few more drops, or pull them out and squirt a little directly into the hole. Don't use accelerator. You want a slow cure time. You want the glue to soak deep into the wood. It is not an adhesive bond between the pin and wood we are going for here. Any such bond is broken the first time you turn the pin. The glue soaks into the wood, swells it, and sets. It reinforces the cellular structure of the wood. It reestablishes the interference fit with the wood. It is the wood gripping the pin, which is exactly what we want. But be patient. If the block is dry it may take a few days for it to achieve full gripping power. Blessings, Dean
