  • 2-by-4s for the tabletop, cut to the desired length and width
  • Ten 2-by-4s for the legs and stretcher rails
  • Four 2-by-8s
  • One sheet of ½-inch plywood, slightly larger than the tabletop
  • Sixteen 4-by-3/8 carriage bolts with nuts and washers
  • 3-inch wood screws
  • 1-inch flathead screws
  • Clamps


  1. Glue four 2-by-4s together and clamp until dry. Repeat to create enough for the tabletop’s width.
  2. Glue the four-piece sets from step 1 together to form the tabletop and let dry.
  3. Sand the top of the tabletop until smooth.
  4. Flip the tabletop over.
  5. Cut two 2-by-8s to the width of the tabletop for the end rails.
  6. Fasten the end rails along the width of the tabletop with 3-inch screws until flush with the tabletop.
  7. Cut two 2-by-8s four inches (102 millimeters) longer than the tabletop for the side rails.
  8. Fasten the side rails along the length of the tabletop with 3-inch screws until flush with the tabletop. The ends must be even with the outer face of the end rails.
  9. Cut two 2-by-4s four inches (102 millimeters) narrower than the tabletop for stretcher rails.
  10. Stand the stretcher rails on their side edges, between the side rails and one-third in from each end rail. Fasten the stretcher rails to the side rails with 3-inch screws.
  11. Attach the side edge of a 2-by-4 to the face of another 2-by-4 with 3-inch screws to form a leg. Repeat to make three more legs.
  12. Place each leg inside a corner of the table.
  13. Drill 3/8-inch holes through the rails and legs.
  14. Insert the carriage bolts from the outside. Secure them with washers and nuts.
  15. Mark each leg 12 inches (30.5 centimeters) from the bottom.
  16. Cut two 2-by-4s to fit between the legs along the length of the tabletop as bottom side rails.
  17. Align a side edge of each bottom side rail with the marks. Fasten them to the legs with 3-inch screws.
  18. Cut two 2-by-4s to fit between the bottom side rails along the width of the tabletop as bottom end rails.
  19. Insert each bottom end rail between the bottom side rails. Fasten them to the legs with 3-inch screws.
  20. Turn the workbench right side up.
  21. Attach the plywood to the tabletop edges with 1-inch screws [source: Designing a Workbench].


1. What materials do I need to build a workbench?

The materials you need to build a workbench depend on the type of workbench you want to build. For a basic workbench, you will need lumber, screws, a saw, a drill, and a measuring tape. If you want to build a more advanced workbench, you may need additional materials such as plywood, metal brackets, and a workbench vise.

2. What size should my workbench be?

The size of your workbench depends on the space you have available and the type of work you will be doing. For a general-purpose workbench, a good size is around 6 feet long by 2 feet wide. If you need a larger work surface, you can increase the length or width as needed. Just make sure that the workbench is not so large that it takes up too much space in your workshop.

3. What kind of workbench vise should I use?

The type of workbench vise you use depends on the type of work you will be doing. If you will be doing woodworking, a woodworking vise is a good choice. For metalworking, a metalworking vise is a better option. A bench vise with a swivel base is also a good choice, as it allows you to rotate the workpiece as needed.

4. How do I attach a workbench top?

To attach a workbench top, you will need to first attach the frame of the workbench. Once the frame is in place, you can attach the top using screws. Make sure that the top is level and that the screws are evenly spaced. If you are using a large workbench top, you may need to use additional support brackets to hold it in place.

5. Should I use a finish on my workbench?

Using a finish on your workbench is a good idea, as it will protect it from wear and tear. A polyurethane finish is a good choice, as it is durable and easy to clean. You can also use a stain or paint to give your workbench a unique look.

6. How do I add storage to my workbench?

To add storage to your workbench, you can add shelves or drawers to the frame. You can also attach pegboard to the back of the workbench to hang tools. If you need more storage space, you can build a separate storage cabinet or shelving unit.

7. What safety precautions should I take when building a workbench?

When building a workbench, it is important to take safety precautions to prevent injuries. Always wear safety glasses and ear protection when using power tools. Make sure that the workbench is stable and level before using it. Keep the work area clean and free of clutter, and keep tools out of reach of children.
