I have a few questions about your elevator design. How much clearance are you putting in between the round surface of the bearing and the aluminum it's rolling on? Also, how difficult was it to get the tolerances needed to make it roll smoothly?
EDIT: Why did you decide to go with cascaded over continuous?

We've done 0 and had it work, there is some slop in the holes interfacing with the bolts that help.
You can add more if you're concerned with manufacturing tolerances.
It should be pretty easy to hold a few thou accuracy on manual mills and routers.
As for cascade versus continuous... A lot of reasons. Just in rigging alone it's FAR easier. The videos I posted on it talk through it a lot. The ability to do whatever power transmission you want for the first stage is very nice.
The fact that both stages move up together puts the carriage centered in the 2nd when the 2nd is centered in the rigid frame, greatly reducing the chance of a carriage popping out.
