A homemade see saw is a very easy project that can change an empty space into a personal backyard playground for a child. Also called a teeter-totter, this playground equipment basically comprises of a narrow long board that is either supported or suspended in the center, allowing one side to go up when the other comes down. Metals and plastics are also used to make see saws, but wood is generally preferred when making this backyard project at home.
Step 1: Making the Seat Board and Brace Board
Find an area in your backyard that has room for a See-Saw and remove any objects that might hinder its up and down movement. To prepare the seat board of the See-Saw, cut one of the 2 x 8 inch boards 9 feet in length. Cut the other 2 x 8 inch board to the same length in order to make the brace board.
Step 2: Constructing and Planting the Posts
To make vertical posts for the See-Saw take two 2 x 8 inch pieces of wood and cut them at least 3 to 4 feet in length. Remember to sand the edges using a sandpaper to make them smooth. Plant these posts in the ground after digging two holes in it. These holes need to be at least 4-feet deep and 1-inch wide to provide a strong foundation. Dig even deeper if you live in an area that can get frosty. Use concrete to fill these holes so the posts are set securely in the ground.
Step 3: Make Notches
Using a jigsaw, cut U-shaped notches, 2 inches deep in the center of the brace board and at the top of the upright boards. These notches in the top of each upright are made from the galvanized pipe to hold the pivot bar.
Upturn the brace board so the notches are facing down and fix it to the top of the upper side of the seat board using galvanized screws driven every six inches along the length.
Step 4: Make the Pivot Bar
For the pivot bar, place a piece of the galvanized pipe in this notched area, allowing a bit of it to overhang on each side. You can additionally protect the pivot bar by adding pipe straps. Drill holes in both the uprights and place metal dowels there to ensure the pivot bar remains in place.
Step 5: Make the Handles and Paint Your See-Saw
Make the handles of the See-Saw using marine rope. Drill two holes that are roughly 16 inches from the end of the seat board. Insert the rope and go on to tie knots so that they do not come loose. You can even consider singeing the ends of the rope so as to avoid it fraying.
Once you are done, have a look to see how your See-Saw looks. Smooth any splinters or sharp edges with your sand paper and apply at least two coats of lead free oil based paint to protect your See-Saw against the weather.
