I built another of my own design Spacerail ball machines. I call it Poleopolis because it has so many poles. It contains my new dumper element. I built my dumper element with my dad, and it is made out of wood and metal. It takes 3 balls to tip the mobile track. See image below.
For this Spacerail ball machine, I did something I have never done before: horizontal poles! Below are the pictures of the two horizontal poles in this ball machine.
Below are more pictures of Poleopolis, and its video.
