Building an Outdoor Bench Swing Building an Outdoor Bench Swing

An outdoor bench swing is a comfortable place where you can relax outdoors to enjoy your surroundings. Buying an outdoor bench swing can cost several hundred dollars. With a few basic tools, you could build your own outdoor bench swing and the following article will show you how.

Tools and Materials Needed:

  • 8 feet of 2x4
  • 20 feet of 4-inch by 4-inch post
  • 22-feet of 1-inch by 2-inch  lumber
  • 24-feet of 1/2-inch by 2-inch lumber
  • Concrete
  • Wheelbarrow
  • Rake
  • Water
  • Hand auger
  • 6 2-inch by 3-inch base plates
  • 1/2-inch diameter by 1 1/2-inch long galvanized wood screws
  • 1/4-inch diameter by 3/4-inch long galvanized wood screws
  • 1/4-inch diameter by 2-inch long galvanized wood screws
  • 2 galvanized ductile iron swing hangers (with 3/8-inch diameter bolts)
  • 4 eye bolts (1-inch diameter hole)
  • 16-feet long chain
  • Drill
  • Drill bits
  • Table saw with miter fence
  • Plumb bob
  • Spirit level
  • Tape measure
  • Flat-sided gravel
  • Open "S" hooks

Step 1 - Cut Wood for Frame

Use the table saw and cut each piece of lumber so that each end is tapered at a 90-degree angle. Out of the 2x4, cut a 7-foot long piece to be the top rail. Cut the post material in half so you have two 10-foot long posts.

Step 2 - Assemble the Frame

Attach one post to each side of the top rail. Use the one metal brace per contact point. Secure the braces in place using the 1/2-inch diameter galvanized screws.

Step 3 - Secure the Frame

Decide where you want the outdoor bench swing and measure a 6-foot by 8-inch gap and mark the end points. Use the hand auger to dig a hole at these points that are two feet deep. Lift the outdoor bench swing up and place the posts into the holes. Fill the holes halfway with the gravel to help support the posts. Use the plumb attached to the spirit level to determine that the frame is level. Fill the holes with the concrete above the hole to a slight mound. It can take up to a week for the concrete to cure.

Step 4 - Cut Wood for Bench

From the 1-inch by 2-inch lumber, cut out two pieces that are 2-inches by 1-inch by 24-inches to create back braces. Three seat bottom pieces need to also be cut that are each 18-inches long by 2-inches by 1-inch. Out of the 1-inch by 2-inch lumber, cut out two pieces that are 5-feet by 10-inch long to use as the back and front frame. Cut the 1/2-inch by 2-inch lumber to fit the length of the bench.

Step 5 - Assemble the Outdoor Bench Swing

Attach the two 5-feet by 10-inch pieces between two back braces using the galvanized screws that are two inches long. Use the 3/4-inch long screws and affix the 1/2-inch by 2-inch across the back of the seat. Continue adding boards until covered with a 1/2-inch space between each piece. Install the hangers on each side of the underside of the top rail. Attach a hook to each and clamp the end together after you place the chain. Install two eye hooks to each side of the seat along with hooks. Attach the chain and close the hooks.
