#74 rolling ball sculpture 4' X 4' marble machine

4ft X 4ft X 18" deep. 3 tracks with a chain lift that delivers about 6 marbles per minute onto the tracks at the top.
I use 1-3/8" glass marbles and all stainless steel. There are 7 spinners on these tracks. 2 large rings, 1 reverse jump-rope spinner, and 4 small rings. They add a nice clink sound and spin around, some fast, some slow when hit by the marbles. The loop d' loop has 5 inversions and ends with an open ended track. The only thing keeping the marbles from rolling right off the end of the track is their back-spin. The back-spin stops the marble quickly and sends it back the way it came.
Completed May 2008

Just a really great rbs. One of the best I've seen. I own #72 that Matt made.  I am jealous of his talent.

I really enjoyed the detailed ramps and the length of the video. Too often it is too short to really appreciate it. Good Job!

I saw this video linked from the Yahoo list...Nice work! I really like the way the train of marbles looked going through the horizontal S-curves when viewed from the front of the sculpture.
