How to Build a Large Workbench

Do you enjoy working in your garage on carpentry projects or perhaps on cars and need a large workbench? A workbench is a great addition to any garage or workshop and provides space for tools and an area for you to do work. This article walks you through step-by-step instructions on building a 10-foot-long by 5-foot-wide workbench. All that is required in accomplishing this task are a few carpentry tools, lumber and hardware.

Difficulty: Moderate

Instructions

Things You'll Need:

• One sheet of 3/4-inch smooth-finish 10-foot-long by 5-foot-wide plywood
• Four 10-foot-long pieces of 2-by-4 lumber
• Six 6-foot-long pieces of 4-by-4 lumber
• Measuring tape
• Circular saw
• Sander
• 2 1/2-inch wood screws
• 1 1/2-inch wood screws
• Screwdriver

Cutting The Pieces for Your Workbench

1. Cut four 4-foot 9-inch-long pieces from two 2-by-4s with the circular saw.

2. Cut the three 6-foot-long 4-by-4s in half to get six 3-foot-long pieces for the legs.

3. Sand all rough edges off the cut pieces as well as the uncut pieces.

Assembling Your Workbench

4. Use the six pieces of 2-by-4 boards and construct a 10-foot-wide by 5-foot wide frame for the table. Put the two uncut 10-foot-long pieces on their edges on the floor parallel to each other 5 feet apart. Place a 4-foot 9-inch long section between them on each end to form a rectangle. Attach the frame together by driving two 2 1/2-inch screws through both ends of the longer pieces into the shorter ones.

5. Place the remaining two 2-by-4s inside the frame for the support beams. Position them parallel to the other 4-foot 9-inch pieces and equally spaced between them. There is about a 3-foot space between all four pieces. Attach the beams to the frame by driving two 2 1/2-inch screws through both 10-foot sides into the beams.

6. Lay the piece of plywood over the frame and line it up. Screw it to the frame by driving 1 1/2-inch screws down through it every 6 inches around the edges into the frame including the support beams.

7. Flip the completed section of the table over on its top. Screw in four pieces of 3-foot long 4-by-4 into each inside corner of the frame for the legs. Sit one 4-by-4 piece on end against each inside corner and drive the 2 1/2-inch screws through the frame into them. Use two screws on both sides of the frame that each leg touches.

8. Attach another 3-foot-long 4-by-4 in the center of each 10-foot side in line with the corner legs. Drive two 2 1/2-inch screws through the 10-foot sections of the frame into them.

9. Turn your table over on the six legs. Drive two 1 1/2-inch screws through the table top into all six legs for extra sturdiness.
