Step 1: Preparing the Panel
Start by cutting all the dados on a single panel. This method simplifies the process and reduces the chance of error. Set the blade height to about one eighth of an inch and make a test cut on a scrap piece of plywood to ensure accuracy.

Step 2: Cutting the Dados
Set the fence 2 inches away from the blade and run the panel through for the first cut. Adjust the fence to widen the groove so it fits a quarter inch piece of plywood. After several passes, you should have all the dados cut.

Step 3: Dividing the Panel into Parts
Once all the dados are cut, divide the panel into its respective parts. Cut the left and right sides first, as the inner dividers need dados on both sides. Repeat the dado cutting process on the opposite face to ensure they mirror each other.

Step 4: Assembling the Outer Frame
Using screws and butt joints, assemble the outer frame first. Use clamp squares to ensure the corners are square. This design is simple, but you’re welcome to incorporate more advanced joinery if desired.

Step 5: Installing the Middle Dividers
Install the middle dividers using spacers cut from scrap MDF for accurate spacing. Secure the dividers with screws, and then attach a back panel using glue and brad nails.

Step 6: Creating Pullout Trays
Next, cut even-sized blanks for the pullout trays. Shape a pullout tab and ensure it fits smoothly within the dados. Use a bandsaw for cutting, and clean up the curves with a spindle sander for a polished look.

Step 7: Mounting the Cabinet
To mount the cabinet, use a French cleat system. Tilt the blade to 45 degrees and rip a piece of plywood in half. Glue and secure one part to the cabinet and the other part to the wall using Tapcon concrete screws.

Step 8: Organizing Your Sandpaper
Now it’s time to load up your sandpaper organizer! Use a label maker to categorize your 6-inch and 5-inch sanding discs, along with sanding sheets and accessories. Keep everything neat and easy to find.
