Step-by-Step Instructions
1. Cut the 37.5" boards into four pieces for the vertical supports and three pieces for the horizontal connectors.
2. Drill pocket holes at both ends of the 37.5" boards for attaching the shelves.
3. Assemble the first module by attaching one 57.5" shelf to two vertical 37.5" supports using pocket screws.
4. Add two more 57.5" shelves at equal intervals, securing each with pocket screws.
5. For the horizontal connectors, attach the three 37.5" boards at the back of the module, ensuring they are flush with the tops of the side supports.
6. Repeat steps 3-5 for the remaining modules.
7. To connect modules, drill corresponding holes in the sides of the vertical supports and use dowels to lock them together.
8. Sand all surfaces and edges for a smooth finish.
9. If desired, apply wood stain or paint, followed by a protective finish to enhance durability.
