How to Build a Workbench in a Shed

Cutting the Wood

• 1

  Determine the size of your workbench. The size of the work bench is really your choice but for the purpose of this article, we will make a workbench that is 50 inches wide, 24 inches deep and 36 inches tall.

• 2

  Cut the side rails from the 2x4s. Cut four pieces 47 inches long.

• 3

  Cut four pieces for the legs, 36 inches long.

• 4

  Cut two more pieces of the 2x4 for the ends. These should be 24 inches.

• 5

  Cut two pieces of the OSB, each 24 x 50 inches.

Assemble the Frame

• 6

  First assemble the two long sides. Attach a side rail to the tops of two legs with four screws, so that the legs are at a 90-degree angle to the side rail. Then attach a second side rail about six inches from the bottom of the legs for added support. Repeat this step for the other long side.

• 7

  Attach an end rail at a 90-degree angle to the right side of each side rail. This will create two "L" shaped sections that match up.

• 8

  Join the other ends of each end rails to the adjoining side rails to create the frame of the workbench.

Adding the Top and Shelves

• 9

  Flip the frame back over so that it is right side up. Now place one of the OSBs on top of the frame and line it up so that it fits perfectly on the frame. Secure the corners of the board, using deck screws, to the four end posts.

• 10

  Cut square notches into the corners of the second board, which will serve as a shelf. These cuts should be 3 x 5 inches.

• 11

  Place the shelf into the frame, on top of the lower side rails. You will have to insert it in at an angle and then lower it to get it to fit right. Once the shelf is properly positioned, secure it with a few deck screws.
