The dimensions of this build will be based on the dimensions of your cabinets. Therefore a comprehensive cut list is not included.
Begin measuring the entire width of your cabinets.
Things to consider when measuring:
- If there are several cabinets in a row, measure the entire width of the adjoined cabinets.
Width of Cabinets + ½” (overhang) + ½” (overhang) = Length of 12 ½” & 10” horizontal boards.
- If the cabinet series dead ends into a wall.
Width of Cabinets + ½” (overhang)= Width of Boards 12 ½” & 10” horizontal boards.
- If the cabinet series dead ends into walls on both sides= Width of the cabinets= Width of 12 ½” & 10” horizontal boards.
The depth of “Upper Cabinets” is fairly universal. However, for clarity sake, you take the depth measurement of your cabinets and add ½”.
I used 3/4″ Plywood for all of my boards. In order to hide the exposed ply I used edge banding to wrap my boards edges.
Before assembling I prefer to sand my boards.
Secure the sides to the top board by driving 1.5″ screws through the top board and into the sides below. Use the diagram below for dimensions and spacing.
Attach Bottom of Under Cabinet Shelf
Using 1.5″ screws secure the bottom of the shelf by driving screw through the bottom shelf and into the side supports above it. ( See diagram below for more dimensions and spacing.)
Attach Back Support for Shelf Under Cabinet
Using 1.25″ pocket holes screws secure the upper back support to the interior of the shelf. See the below diagram for dimensions.
Assemble Base of Under Cabinet Shelf
Using the below diagram drill pocket holes and attach the back bottom support to the sides of corbels. ( The dimension of this board will vary based on your cabinets.)
Width of Horizontal Boards – 1/2″(overhang) – 1/2″(overhang) – 1 3/4″ (corbel) – 1 3/4″ (corbel) = Interior Bottom Support
Attach Base Support
Using DAP Weldwood and 1 1/4″ pocket hole screws, secure the support to the bottom of the shelf. (See diagram below for dimensions and spacing.)
