Double ovens range in size from 24 to 36 inches wide and can be as tall as 96 inches. Building a custom wall cabinet for a double oven requires the dimensions for both ovens so the overall cabinet design fits those dimensions. Ready-made cabinets have oversized cabinet fronts in the double oven area that the consumer cuts to the size they need with a jigsaw. In some cases, double oven cabinets will have no back in them. This allows for easy access to electrical or gas connections.
Lay the 83 3/4-by-23 1/2-by-3/4-inch plywood cabinet sides on a worktable. From one corner, make a mark at four inches on both the long and short sides. Put the triangle square on the marks and draw lines to create a square. Cut this out with the jigsaw. Repeat this on the other piece of plywood.
Fasten the 19 1/2-by-4-by-3/4-inch plywood pieces to the sides behind the cutout with the box nails. Measure from the top of the cleat and make a mark at 11 3/4 and 12 1/2 inches. Set the framing square on the marks and draw lines across the plywood. Make marks from the other end of the sides at 14 1/4 and 15 inches. Draw lines as you did before.
Stand one of the cabinet sides up so the cutout is facing up. Put one of the 28 1/2-by-23 1/2-by-3/4-inch pieces of plywood on top of the cleat against the cabinet side and secure it with finish nails. Repeat this with the three remaining 28 1/2-by-23 1/2-by-3/4-inch pieces between the lines drawn and at the top of the cabinet.
Apply glue to front edges of the cutout. Attach the 30-by-4-by-3/4-inch piece of plywood to the front of the cutout with the finish nails. Turn the cabinet over on its front.
Glue three edges of one of the 28 1/2-by-4-by-3/4-inch plywood pieces. Place one between the sides and against the bottom side of the second shelf from the bottom. Secure it through the cabinet sides and then the shelf with the finish nails. Repeat this with the remaining two pieces between the sides and against the bottom of the next two shelves.
Frames and Doors
Place the two 26-by-2-by-3/4-inch plywood pieces between the 12 1/2-by-2-by-3/4-inch pieces with the 2-inch side flat on the table. Secure the four pieces to each other with the corrugated fasteners to create a rectangular frame. Repeat this with the 15-by-2-by-3/4-inch pieces and the remaining 26-by-2-by-3/4-inch pieces.
Set the two pieces of 51 1/2-by-3-by-3/4-inch plywood on the worktable so their long sides are touching and they are even on the ends. Measure from one end and make marks at 22 5/8 and 28 7/8 inches. Put the triangle square on the marks and draw lines across the material. Separate the pieces to place the 24-by-6 1/4-by-3/4-inch pieces between them, one at each end and one between the lines. Secure them with the corrugated fasteners.
Turn the cabinet over on its back. Secure the 15-by-30-inch frame at the top of the cabinet with the finish nails and the 51 1/2-by-30-inch frame just below it and the 12 1/2-by-30-inch frame at the bottom.
Install the cabinet door hinges on the 12-by-14 3/4-by-3/4-inch plywood and the 9 1/2-by-14 3/4-by-3/4-inch plywood doors according to the manufacturer's instructions.
Cut the frame in the middle according to the double oven dimensions with a jigsaw.
Set the nail heads with a nail set and fill the holes with putty if desired.
Do not leave loose nails and power tools within the reach of small children.
Do not apply a finish to the double oven cabinet without proper ventilation.
