Step 1: Take apart the boards
Step 2: Cutting boards into uniform lengths
Step 3: Sanding the boards
Step 4: Attach the basic box boards
Begin by putting a small line of wood glue (Titebond II works really well and it is water/weatherproof) on the ends of the small shelves and attach them inside the long pieces, as shown in the photo. Clamp lightly if desired, while inserting the center dividers.
