1974 ES-175 Loose Brace Repair

Back Camera Back Camera This ES-175 had a sunken top due to a loose brace on the bass side.  The brace had separated at both ends with about 2 inches attached in the center.  It was easy to separate it completely from the top with a palette knife. Luckily the pickup holes provide a little extra access but it is still challenging to clean the old glue from the inside of the top. I used sandpaper stuck to a rare earth magnet to get to the areas that were not accessible by hand.

After cleaning the brace and the inside of the top I was able to reglue the brace using a clamping caul made from the contour of the back. The contour was traced on plywood using a compass and bandsawed to shape.
