Rotating Balltrack Loop

[Diamabolo]

Marble Run in Motion
After seeing @marblemachinepolyhedron1751's marble runs, it was clear I wanted to try something like that.
A long time and frustrated pauses later, this is my first attempt.
A lot of fine-tuning and hose cutting were required.
 

 

more details...

That is truly amazing!!! It is awesome!! 

[MAB]

That is very clever. Is it possible to adjust the track so that the ball never stops apart from at the start/finish?

That is darn awesome.
Mindblowing how people come up with these design - I feel humbled...

That would work. The difficulty is caused by the different speeds. Therefore, it's easier if the ball starts with a defined start.

Nice!

What if, you add another track there? 2 balls running?

This would be a good further projekt....after  the next rigged hose bricklink order

[Shiva]

Good luck and would be nice to see it :)

This is astonishing! I really want to try to make one myself now. Is there anyway to get a list of the sizes for the hoses you used? Thank you for sharing.
