Perhaps you know this, but avoid using CA glue for gluing plate felt & cloth. I tried doing this with CA glue when I did not want to wait for the drying time needed by other glues I normally use. Much to my dismay in several weeks I had to completely restring the piano because the chemical reaction had severly rusted the strings where they contacted the felt and cloth. Not a good way to learn. Thought this might be of some interest. I learned sometimes the quick fix is not always the best fix. As someone just starting in this business, I'm here more to learn than to advise. But, I've been a chemist for twenty years, and, perhaps, can shed some light on this topic from a different angle. After mulling over the facts, doing a little research, and re-reading the thread a couple of times, it seems to me Don's problem was from fuming. He mentions that he didn't want to wait for the drying time of other glues, so maybe he closed up the beast too soon. Even though CA glues bond quickly, they can take a couple of hours up to a couple of days to fully cure. The fumes will react with any moisture they contact (felt's full of it, probably anywhere the strings were touched, wood moisture, etc.) and could cause corrosion on strings where they contacted the felt. It's true that the polymer formed is waterproof, so any "treated" metal, such as tuning pin, hitch pins should be okay. So maybe the take-home lessons is to use CA glue when appropriate, but for your safety and the piano's, have good ventilation, and maybe leave the case open for a day or two.
