Pyramids have fascinated us for centuries, with their grand scale, and the mystery surrounding their construction. While the construction techniques of the great pyramids are still a puzzle, there is no such ambiguity around building model pyramids. Wooden pyramids are often made as decoration pieces, but why not go one step further and make a model pyramid into a box? That way you can store your treasures inside, just the like the ancient Egyptians used to.
Measure and cut a 5 inch square of plywood using the set square and jigsaw. Cut the square edges at an inward angle of 25.5; use the protractor to measure the angle.
Measure and cut four right-angled triangles. The base of the triangle should be 5 inches, and the other two sides 3.5 inches. Cut the base of the triangle edge at a 25.5 degree inward angle and the sides at a 22.5 degree angle---the angled edges will allow the pyramid to fit together with nice, clean corners.
Dry fit the pieces together, the square flat as the base, and the triangles forming the sides of the pyramid. The angle edges should form flush seams, but sand them if necessary to get a good fit. Mark the connecting pieces with a pencil, so you'll know which pieces fit together. Set one triangle aside.
Run a line of glue over the connecting edges of the pyramid, reassemble and clamp tightly while the glue dries---one side of the pyramid should be open. Take off the clamp once dry.
Fit the two small hinges over the side of the remaining triangle, equal distance apart. Screw down with 1/4-inch screws. This is the door of the box.
Position the triangle door of the pyramid box over the opening in the pyramid, aligning it so that it fits into the opening. Screw down the remaining portion of the hinges into the side of the adjacent triangle edge of the box, so the door is attached.
Sand and paint your pyramid box---painting in a sandy yellow colour, then painting on the brick lines in a darker golden brown is one idea. Be sure to let the paint dry with the door of the box open.
