An older instrument has a number of deformities to the top table. I'm not sure, but I assume these deformities developed gradually over many years. In particular, the table has sunk around the feet of the bridge, and has somewhat bulged out in the lower bouts, especially on the treble side. One f-hole "wing" now curves out from the surface of the table, the other curves in. The instrument has an excellent sound, but I'm wondering about its future with all the movement that has happened in the table. I know that I need to have a qualified luthier inspect it for possible risk of table collapse, but assuming there's no imminent risk of collapse, has anyone had any luck at having a table reshaped to original form? If you didn't have to do so (because of imminent risk), would you bother?
