    I have two different acousic guitars that I worked on about a year ago or so and glued new bridges on to both of them and now both of the bridges are starting to lift off. So I am trying to find out what I did wrong. I sanded both surfaces ( top of the guitar) bottom of the bridge. I used Elmer's wood carpenter's glue and I used 3 U Clamps to attached the bridge. One dead center and one each on each side of the bridge and they seemed totally solid after the glue had dried. I let them sit for 3 days before I released the clamps. Could it have been the type of glue I used? What does everyone else for this? Please give me some feedback as I have them coming in next week for repair.

    Thanks,

    Gary

    BOTH BRIDGES ARE ROSEWOOD. The wood on one guitar is mahagony and on the other it is spruce.

    Thanks,

    Not a problem, but the answer is really weird. One is lifting at back left corner and the other one is lifting in the middle front. I haven't seen the middle front one yet. I am picking it up this evening. I also remember on that one that there was damage to to wood under the bridge and I had to use a wood filler for part of the repair it that makes a difference.


    Thanks,

    Gary

    Filler . Sounds like you may have answered your own question .
    The other sounds like you may not have gotten down to virgin surfaces and/or a lack of glue .
    When you redo this , you may want to give the rosewood a swipe with acetone to remove any oils , although this is not typical with rosewood . More of an ebony issue , but it can't hurt .
    Assuming you are getting a good clamp , there are few issues to what you are doing . Just basic stuff .
    You want to squeeze out a bit of glue around the entire bridge , but not squeeze it all out .
    Cleanup is easy after about 5-10 minutes .
