Loose back brace :: 1958 Gibson LG-O
Here I'm gluing up a loose back brace with a scissor jack inside and two cam clamps on the outside. The center seam is also open so that will be glued up as well.

2014 Martin Custom X Series D :: high pressure laminate explosion
This X series Martin Dreadnought has high pressure laminate (HPL, Formica, etc) back and sides. The guitar slipped off of a strap and fell onto a hardwood floor. The back broke loose from the treble side (neck-to-tail block) through the linings. The first back brace was also split on the bass side. Here everything is being glued back together with a combination of spool clamps, cam clamps, scissor jack and brace jack. Luckily this was not solid mahogany, else the damage would have been much worse.
This Alvarez had a Planet Waves soundhole plug installed to help block feedback when plugged in. Upon removing the plug I found that there was a broken piece of the soundhole edge holding on by a thread. A little hot hide glue, a piece of plexiglass and a modified brace jack were used in the repair.
