Bolt sprocket to wheel. Stick big bolt through spacer, sprocket/wheel/bearing setup, apply locknut/jamnut/other locking fastener. Done. (Or, use a length of steel rod from McMaster, thread the ends with a die or drill for a cotterpin. Still a minimum-machining job.)

A live axle requires a keyway/hex feature and some sort of retention for the wheel/sprocket separate fro each other.
