Lower Ball Lift
The rolling ball sculpture (kugelbahn/marble-run), is coming along slowly but surely. The video shows the lower ball lift working. The upper lift arms will attach to this same frame and lift the ball another five-ish inches.
I bought some nicely colored 1” marbles to try this time. I normally use 1” steel balls, but the marbles might add a nice touch of color. It will depend a lot on how I build the track, since a machinery style will look good with marbles but an organic style might look better with steel balls.
