I’m not exactly sure how many “teeth” = 1 stud, but I know it’s not a whole
number.

It’s exactly 2.5. 10 teeth on a gear rack, divided by 4.

I’m using two upside-down 1x16 TECHNIC beams to straddle 24-tooth gears on each
end (see my great ASCII art below, top-down view, not to scale). I might not
even need tension in the chain at all; the tread links slide on the flat bottom
part of the beams, and that seems to work fine. I haven’t yet built a support
structure to test the chain for real.

My “buckets” are simple and work pretty well, even at steep angles. Every fourth
tread link has a 1x4 plate on it, and on each plate are two of those 2x2
right-angle plates making a squarish area for the ball to rest in. Again, some
beautiful ASCII art:
Step 1:
_______
|_______| <- that's a 1x4 plate
Step 2:
_ _
| |_ _| |
|___|___| <- those are right-angle plates
What other bucket designs do people have?
