Rolling Ball Sculptures | Marble Machines by Steven Kozari Frank

Rolling Ball Sculpture No.3

It's my first motorized rolling ball sculpture, and has a helical lift mechanism. The tracks are stainless steel, the frame is steel. It has a very durable black powder coating which is also UV resistant. It has features like switches, a multi-ball mechanism, balls on tracks, a loop, wavy tracks and a horizontal spiral, three tracks in total. The video below shows it well. Width 800 mm, height 580 mm, depth 300 mm. Marbles are 25 mm.
