How to Build a See Saw?

You can easily build this simple seesaw. Begin with a used tire that will be the mobile base. Build the wood framework and put the tire on top of a piece of plywood. Fill the tire partially with concrete and insert the framework. Add more concrete if needed to fill in any low places and allow to dry completely. Attach the pivot bar and build the seesaw plank and install it. For more information look here:
