This Gibson J- 200 came in with a nasty crack in the top seam. It measured almost 8 inches in length and traveled under the bridge area.
I found a nice piece of Spruce material to carve thin shims to fill in the area affected by the top separation
The crack width measures .005. The shims are now ready to be inserted and trimmed. The cleats will then be glued underneath the top in the affected area.
