How to re-glue a bridge
Instruments- discuss specific features, luthiers, instrument problems & questions
oh oh....Maybe the bridge was supposed to be movable!!!!! I NEVER glue my bridges down. I adjust intonation of my dulcimers by making my bridges FLOATING. I know there's been discussions on this before. And I know that some ONLY glue them down or make a little trough to set the bridge in. However, when I've found these old home made dulcimers and fixed 'em up......OFTEN that little trough is way off and that dulcimer was never in tune. Before you glue it down, string up the dulcimer. The strings will hold that floating bridge down. Using a app on your phone or a tuner....... On the lowest string first pluck it to a D or C........ THEN pluck the 7th fret. If it is a perfect octave, your bridge is in the right place. I go even further to see if the 14th fret is 2 octaves perfect. Now if it's SHARP, lower your floating bridge by moving it away from the top of the dulcimer. If's it's FLAT, move that floating bridge up. ALL IN TINY MOVES. Now you can do that with each string after that. Sometimes you'll have the bridge too high....sometimes too low. And as we've talked on here before. Your string height up at the NUT of the dulcimer should be close to a DIME (money) distance. Down at the lower strumming part of the strings, it should be about a Nickle's worth of distance from fret wire to the string.
I read this over and over, I sure hope this is clear. Please anyone help correct me if this doen't make sense. I've loved it when I've made fixed bridges on repair dulcimers become floating bridges. I "think" I hear the dulcimer say, "whew, finally I'm in tune!!" The dulcimer surely has a sweet tone when they are IN TUNE!! aloha, irene
