Repair glue joint?
Hello, how would you treat this?
A classic Swedish made guitar from the early 70s. As you can see on the photos the glue joint is defective and it is possible to insert a thin paper between the top and the bridge. What is there to do, please?

The proper way to treat that is to remove the bridge, clean up the bottom of the bridge and the bridge foot print on the top removing all the glue back down to wood. Then reglue the bridge in place.
It's a very basic job for an experienced tech or luthier and will cost you $50-100 bucks depending.

It's just not possible for me to know. You can try it if you want, it probably won't hurt anything. Just go slow and if you hear a ripping noise then it's probably going to come off. But it won't shoot across the room either it will just peal off. The risk being that it takes some wood splinters with it.

The top is Romanian spruce of (reasonably) close grain and the saddle is Brazilian rosewood. Tell me if I´m sacreligous, but if you drill two holes in the bridge for location…
Not only that, there seems to be, when looking inside, a cut-off screw in both the bridge and the fingerboard (but just one in each).

Usually where there are screws in the bridge there is some sort of MOP inlay over the screw head. So that's a bit odd. Where is the location of the screw relative to the bridge? It's not unusual to have a pin or two to hold the bridge in the proper place for gluing. And when you say screw do you mean a machine screw with a nut or a wood screw?

The "screws" seems to be going in the center of the guitar (on a straight line of symmetry). As far as I can see they are not magnetic. What they really are is a guess. Some sort of dowel pins...?
The one under the bridge is through the center brace. The one under the fretboard is just parts of an inch from the heel block. I tried to take photos. Had to be seen through a mirror. The item, mainly looks like a drilled hole and is marked within red area. The photo under the fretboard is the easiest to see and get anything out of. https://www.dropbox.com/s/cqyiht1wgj...01365.jpg?dl=0 https://www.dropbox.com/s/zntfxwxgek...01366.jpg?dl=0 https://www.dropbox.com/s/2qrl9bv11w...board.jpg?dl=0 Last edited by Henning; 12-16-2019 at 12:52 PM.
