The wood lid front piece is completely broken away from the lid top, under the cover's tweed fabric. This dark shadow is cast by loose covering that folds backward with the broken lid front when the case is opened. Repair is done by (1) heating and removing the tweed covering flap from the interior of the lid front piece, (2) injecting glue under the lid top & front covering via access through the broken wood separation and smoothing the glue evenly under the lid top & front covering, (3) applying glue to the broken wood to create a new joint, and clamping the joint from the outside and inside to keep the joint in place, (4) allow the repaired joint to dry, (5) restrectch the interior covering and glue it back in place. The glue required by Industry Standard is a glue that melts under moderate heat and therefore allowing any future repairs to be done by applying heat to make it workable again. |
