Ron Ok... so I have been digging in the archives and old reprints of Journal articles and come up with the following.... This particular kind of false beating comes from the fact that the Bridge pins are able to vibrate somewhat freely inside the wood of the Bridge, and it doesnt seem like there needs to be a great deal of "looseness" to get this kind of false beating started. ("Bridge Pin" and "False Beats" got a lot of hits on the archives btw) It also seems like its almost impossible to avoid as it would require a perfect fit all along the length of the bridge pin in the bridge wood, and this fit (if it can be so acurately bored and pinned to begin with) is going to be wrecked sooner or later by variance in climate through the years, the sideways stress on the pin, and a few other factors. Adding CA or epoxy would seem to help to begin with, if done well, but I suppose in the end climate concerns would wreck this fit as well. As to re pinning with next size up pins. I am wondering if heating the hole so that the pin just fits in with an easy tap would be an idea ?? That way when the would cools down again it would expand around the pin and make a real tight fit ???? All this brings me back to the old... sheeshh... there has got to be a better way.. grin... One other question I am not clear on. Is it then necessary for the strings energy to be transmited deeply with in the bridge via some kind of insert (like the bridge pin) or could that be accomplished just as well by contriving some way of keeping the string "pressed" firmly onto the top of the bridge alone ??
