ABSTRACT:
A panel-forming system including a plurality of bulkheads and one or more extensions. A first group of the bulkheads are used to define the overall dimensions and shape of the panel, while a second group are used to define at least one aperture formed into the panel. The aperture extensions are configured to allow various-shaped recesses to be formed in the panels adjacent the apertures, and are made up of a bulkhead-engaging portion and a separate recess portion that extends from and cooperates with the bulkhead-engaging portion. The surfaces of each bulkhead-engaging portion include a plurality of chamfers to create complementary surfaces in the panel being formed.
