In for repair, a 1935 Gibson jumbo

This guitar had some very poor repair work around the bridge. The original bridge plate was gone and a 1 x piece of pine put in its place. Bolts, screws, and epoxy did not fix what ever trouble it was supposed to. The bridge was still pulling off.

To repair this guitar, the mess first had to be removed. The epoxy was softened with heat, applied directly to the bridge. Once the bridge was out of the way then the 1 x piece of shelving material needed to come out. It was epoxied in, so pulling and prodding until it finally came out was the only option. The bridge plate and a large portion of the top was missing, leaving a large hole in the top so I decided to put in a larger bridge plate. Cleaning up the top was difficult as most of the epoxy had to be cut off, taking finish with it. The finish was repaired making use of violin retouching techniques as this would result in less original finish removal. The repair came out well.
