Here is the third ring finished.
And the fourth!
I used yellow-sized bendy parts to create a little decoration and color.
I also used grey-sized bendy parts to add some dimension to the inside.
And finally, the last ring!
I've got spaces marked out for each gondola, so now I just have to create them.
I am figuring out how I am going to motorize it while still creating a stable enough spindle for the giant wheel to ride along.
This is the view from inside the wheel. I decided to use tan pieces to keep the wheel in place along the axis. I then took 4 yellow connectors and 6 red rods to create the part that will help to turn the wheel.
And as you can see, it is taller than I am. It will easily be over 6 feet tall when I finish up with it!
