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?

Well, my lift for loading the train car uses both chain links, and tracks. Each
track has a 1x4 tile on it, and the balls roll up.

That's close to what John did on his roller coaster:

This red module: http://www.brickshelf.com/gallery/Hassenplug/GBC/10stevechainlift.jpg
uses a pair of axle joiners: http://www.peeron.com/inv/parts/6536 with some #3
axles. Brian came up with this, and it works very well.

I have just placed wheels regularly spaced along my chain to support it.

Mine are similar, but use a 1x3 plate with a 1x1 plate with tooth on each end,
at a slight angle, and another 1x3 plate on top. I was finding that even with an
accurate feeder, they were occasionally bouncing over the side when I used 1x2
plates on each end.
