Are you referring to making the sprockets fit on the shaft easier or something like that? We use a tool I call the "vertical lathe" (there actually is such a thing, but this is not it). We pop the shaft into the chuck of the drillpress, spin it up and put a nice file, sandpaper, or preferable emery cloth to it. Works every time. Slightly less ghetto.
