I bought two sets of each, which should give me 72 conveyor belt links and
200 chain links. With 2.5 gear teeth/stud and 2 teeth per link, that
should be enough for a conveyor belt that is about 100 studs long (or more
than one belt, of course, which is my goal).
That is assuming that the chain links are actually useful in making a
conveyor belt. I had assumed that most conveyor belts were made with the
chain links and an occasional belt link to act as the "bucket" that pushes
the balls up. However, after following the recent discussion, it seems
that maybe people are using the conveyor belt links exclusively?
Can you build an effective conveyor belt with a mix of the two parts
above? I sure hope so, because at $0.28 per link, conveyor belt links are
not exactly cheap. Not that $0.10 per chain link is great, but it's
better...
I'm thinking of building a sluice-type chute with a chain in the middle,
with a conveyor belt link spaced regularly along the chain. Something
like this, where 0 is a chain link and I is conveyor link. The I's are
the chute itself.

The balls would obviously rest on the bottom of the sluice, rather than on
conveyor belt links, but they're balls: they should roll just fine! :)
Right?
Does my wonderful ASCII art make sense? If so, will this work? Or am I
stuck with a bunch of useless chain links? :)
