Start by drawing evenly spaced marks along the two 2x4 wood strips to indicate shelf placement. Precision here ensures stable, level shelves.
Adjust your table saw blade height to 1 1/2 inches and tilt it to 45 degrees. Carefully cut along each mark on both strips for clean, angled slots.
For broader slots, use a sharp chisel and hammer to remove material between each slot set, creating ample space for shelf boards.
Secure the two strips to each side of the 3/4-inch plywood board using screws, forming a strong frame ready for your shelves.
