Nice drivetrain

Couple questions:

1. What was the reasoning behind using different-sized wheels for such a drivetrain?
2. I believe you asked me this same question on my first custom butterfly drive, but to this day I am still confused on how to solve that problem . Here's the question: With a chain-in-tube drive like that, does it take into account rivets and other pieces of hardware that share the drive rails?
