Position two 1/2-by-24-by-36-inch side storage boards parallel to each other on their shortest edges. Set a 1/2-by-24-by-24-inch top storage board on top of them and move the side storage boards out to the edges of the top storage board so the outside surface of the side boards is even with the edge of the top board. Use the drill and make holes every six inches down through the top board and into the side board. Drill the boards together with 1-inch wood screws.
Rotate the assembled section 180 degrees so the top board is now against the working surface. Set 1/2-by-24-by-24-inch bottom board on top of the side boards and line them up in the same manner as the top board was aligned. Attach the bottom board in the same manner as well.
Arrange available 1-inch-thick wood scraps in the form of a 3-foot-by-5-foot tabletop. Set four 1/2-by-4-by-34-inch tabletop support boards on top of the tabletop and parallel to each other with their largest surfaces flat against the tabletop. Drill two holes down each support board and into each tabletop board it touches, then drill in 1-inch wood screws, so all the scrap tabletop boards are attached to the support boards securely.
Place the assembled storage section on top of the tabletop. Drill four evenly spaced holes through the top storage board and into the tabletop support boards. Attach the storage section to the support boards with 1-inch wood screws. Flip the table right side up.
Fill any large holes in the surface of the tabletop with caulking and allow four hours for it to dry. Cover the tabletop with a coat of sealant using the brush, and let the sealant sit for four hours. Add three more coats of sealant, allowing four hours of drying time between each coat.
