Once in a while a straightforward repair job starts to grow in complexity upon deeper inspection. An older Martin came in, the owner requesting "a neck set" to deal with rising string action, however it looks like the real issue is not with the neck pitch (there is plenty of back set) but with the top. The top is sinking in front of the bridge, which seems to be rolling with the torque of the strings over the saddle. Looks like the bridge patch is failing to stiffen the top between the X braces.
But upon inspection, the bridge patch has been replaced; by the squeeze-out I can see that it is held with Titebond. Aliphetic resin doesn't slip and reconstitute when it is heated like hide glue does. So now the question is: can I heat the bridge patch to remove it without causing damage to the adhesion of the adjacent braces and tonebars? My impression is that its bond will let go at a higher temperature than hide glue so this is trickier than it would have been.
Has anyone been faced with this dilemma?
