The top two images left and right show where the bass bar has been removed exposing the woodworm tracks. The woodworm love the animal glue which is used to glue up all the joints. Woodworm holes are more often found in the edge work or ribs where they are glued to the belly and back. In this case they found a rich glue source under the bass bar. Above left shows the repair being done fitting four patches similar to a Soundpost patch but elongated. Two thirds the thickness of the belly is remove to allow new wood to be fitted flush with the belly. The square blocks locate the patch for fitting and are easily removed later. The new bass bar is fitted and new studs or cleats are fitted along the centre joint as it looked suspect.
