Faux Wheels

[alr2]

Hi... Just keeping up to date with the extended info here.

Now...
(Bear with me on this)
In order to build like Oliver, you need to think like him.
Example: who the hell would use Lego for details on a droid to be used on a blockbuster Star Wars film? Easy: Oliver!

So with that in mind, I set out to think like Oliver.
One over the things I first thought was what size where the wheels and what on earth could he have used for the balls? (they have to be commercially available)
They're not light.
They're not cheep.
They're no soft rubber.
So I looked REAL close at them.
Then... Thought out of the box.

Here is my evidence and thoughts.
