If you are referring on how to capture hex shafts so they don't move, my preferred method is to capture it by turning the ends on a lathe into round and using flanged bearings on either side. I've also used a combination of Delrin spacers with either shaft collars, E-clips, or tapped ends of the shaft (with fender washers) to retain it.

In the case of the shaft collars, I had the section of hex turned down to round and used an aluminum split shaft collar.
