You can see, even from this view- that bridge is lifting off the corner. This particular bridge is lifting due to the instrument being too dry, causing the top to belly upward excessively. The pics below show in more detail. Apparently the bridge had been repaired prior, although I couldn't see any sign of it. All that had been left were scratch marks and glue residue.
After removing the bridge it had to be planed flat again. The second picture shows how badly warped it is. The areas unaffected by the sanding are warped upward significantly (several millimeters). After tons of elbow grease, I got 'er planed flat again - ready to be reinstalled.
This reglue was a challenge mainly because of the shape of the bridge. All the protruding edges have the tendency to pull upwards on a bulged top (or a top less than flat). I was successful in reseating the bridge - using epoxy for it's strength. Anything less would not work.
