Think of it as a primitive bushing. Woburn has used a 0.5" bore on the drive wheels for at least the last five years, each time using a wooden wheel with no special hub. It hasn't failed yet. The shafts are usually embedded in needle bearings or bronze bushings, and are free to rotate independently of the wheels (since the sprockets are themselves bolted to the wheels, with spacers as necessary). Last year, confronted with the need to save weight, instead of ground mild steel shafting, Woburn used 6061-T6 aluminum shaft from Home Depot. It was perfectly acceptable for the 3.5" wide wheel wells.
