Hi Andrew I dont see a down side to useing CA glue either. Clearly in significant numbers of instances the application of CA yeilds a result that shows a lesser degree of false beats. So hey... use it by all means. For that matter... as far as that same scope goes... I aggree with Ron N in that useing larger bridge pins is rather a waste of time. On the other hand... there may be another root issue at hand that really causes the false beat that perhaps a large pin in itself addresses. We dont really know. And thats my point... I dont think we know that loose pins in themselves are a determinant in causeing false beats. In fact I rather doubt it because I can find plenty of examples of loose pins that dont exhibit any such falsness. I've even gone so far as to purposely install over loose pins... as in very over loose to check that out and find very often that either no falseness occurs, or even in some cases that false beats that were evident dissapear. This tells me that loose pins per se are probably not the direct cause. But hey !! grin.. as long as CA'ng seems to address whatever is the real cause to the degree it evidently does... then by all means use it. I do all the time. Cheers RicB Ric, I readily agree that CAing bridge pins will not necessarily remove all false beats. Some times that problem isn't at the bridge, sometimes its at the capo or agraffe and sometime it is sympathetic beating from a duplex, front or rear (design issue). I have serviced a piano where bridge cap replacement was not in the budget. There were cracks around the bridge pins in the treble and it was terribly noisy. In desperation I gave it as much CA to drink as it would take. The next day I stopped by to check it out. I'd say 95% of it gone. The rest I can work with. Maybe even reduce. Does CAing the pins work? Has for me. 100%? No. But well enough to add to the arsenal. I can't see a downside to this. Sincerely, Andrew Anderson
