Regluing Gibson Braces
A clean brace reglue is all about taking the time to set things up precisely. Gibson brace ends are notorious for popping loose, and getting them back down again can take some real coaxing.
In the case of this early ’50s J-45, the shrinking pickguard had cupped the top so badly that the upper soundhole brace, X brace, and a finger brace were all loose from the top and tightly sprung. The pickguard was removed, the top ‘ironed’ flat, and the braces are now getting reglued one-by-one.
It’s not uncommon to need to make custom brace-end gluing cauls that are specific to the guitar being worked on. It’s a lot of extra work, but a well-fit caul is critical to a clean end-result and a repair that will hold in the long run.
