Completed sculpture #76

This is my latest project. It stands 5ft high and is 3.5ft wide on each side. A chain lift brings the balls back to the top and releases them into the 4 tracks on this sculpture. This sculpture has several fun elements. First is the Plinko Track Scrambler. 3 of the 4 tracks go into this element and the marbles mix up, taking one of the 3 tracks exiting. The fun part is watching the balls bounce around randomly before dropping off and continuing on the stainless steel paths. The loop d' loop has 7 inversions, and jumps into a basket. See the video of the sculpture here:



One of the paths goes into the Ferris Wheel Lift. The 1-3/8" marble is directed around the outside of a large 12" ring. The ring has tines that catch the marble, and allow the marble to spin the wheel. When the wheel spins there is a smaller ring on the inside that lifts 1" marbles, about 4 inches, onto their own small path. They race out and around before returning to the lift. I have only made two of these elements, this being the second one. I spent a lot of time turning this one over in my head to make sure it was built correctly. I think it came out just right. The most complicated part to making this element was getting the bearing exactly in the center of the large ring. Once that was accomplished, the rest was easier, but no less important. Building slow, is the key to building something like this. Below is a video of the Ferris Wheel Lift.
