I used the Dave Brown Ultimate Spinner cut for the 3W48B2 and a 20 X 10 prop. The whole deal with the adapter cost me around $55 direct from Dave Brown.

Du-Bro makes a prop balancer that uses wheels instead of magnets. It is possible to configure this balancer so that the large prop overhangs the workbench and the axle rests on the lower set of wheels the back part of the axle pushes up on the bottom of the second set of wheels. This way your prop can spin all the way around and it is possible to get a good balance on the prop.
