All these pieces of play equipment were formed using our Universal Fabricator. The Pedal Helicopter and Ferris Wheel were built by myself for my grandkids. The copter cockpit was rolled on the Pedestal Arch & Ring Roller. Caution! It must be noted that when building kid's play equipment extra care needs to be taken for safety. Since all the blades rotate, as the helicopter travels around a center concrete mounted post in a circle, they are made out of a durable foam. I am currently redesigning the helicopter to eliminate the rubber wheel by driving the rotation off of the center post.
