That's a good suggestion, I don't have a wheel hub laying around unfortunately.
3 jaw and 4 jaw just refers to the chuck (part that clamps the workpiece) of the lathe.
Ended up using the slotted mounting holes in the 4 jaw chuck to mount the drum. I just bolted it to the chuck and indicated it on the center bore that locates on the wheel hub.

Happy with the results, should give the shoes a nice mating surface. All 4 took about .030 to .040 to clean up.
