For this contest I'm building a ride inspired by The Zipper:
Here is my current progress:
I started with the rotating arm to get a feel for size and weight. Currently there is a lot of sagging on the chains, I tried to build in a tensioner with springs, but I do not know if it will be strong enough in the end. Also the driving wheels for the chains rely purely on friction, this might be to weak as well. I have an alternative in mind, but first I will create all pods to see what happens with all weight attached.
More to come...
