28″h X 20″w X 18″d – THREE tracks – Chain lift

This is a style of my usual tetrahedron frame, three legs with a ring at the top. I like the three-legged frame as it is easiest to level on any surface. This one has a chain lift and three tracks. 2 tracks splitters feed the three tracks and you can see a loop d’ loop, a tall coil, a ball collector, flat spiral and a collector plate. The collector plate merges the three tracks back into one for the chain lift. DC motor can be speed controlled from slow to fast to fit your mood or audience.

100% stainless steel, TIG welded.
