#75 just getting started; framed and lifted

This is my current rolling ball project - a wall hanging sculpture that measures 22" high X 32" wide. This ball run will have 3 tracks when completed.

This is the frame, it stands off the wall 7 inches so the track can go in front and behind the frame. It gives me more room to work and will keep the track from sticking out too far. The frame is made from all 1/4" stainless steel rod.

I just got the lift installed today. It's a helical lift, and uses a 7rpm DC motor. The tube in the center of the lift is 1" stainless tubing with 1/8" wire wound around the outside to lift the marbles.

Shown here are the two track switches I will need to turn one track into three. Think of it like this; The track from the lift leads directly into the first switch. Two track leave the first splitter-one track is full length and the other just leads to the next splitter. The second splitter has the other two full length tracks come from it, and that makes 3 total. The white plastic is made from a polypropylene rod, cut to 1" lengths and a 1/4" ID self lubricating bronze bearing pushed into the center. The bronze bearing keeps the switch moving smoothly for a long, long time.

The first track I will work on? The loop d' loop!
