The Full Bell sheller has successfully met its criteria of cutting the costs and keeping its effectiveness. The mold for the Full Bell can be used to make shellers of other materials as well.
By experimenting with different kinds of aggregates and cement formulas, a sheller can be produced that
can be lighter, stronger and more cost effective. Just by simply changing the
ratios of gravel, sand and cement in the Full Bell, or by adding fly ash or fibers, the durability will remain the same or even better. The Full Bell has opened up endless possibilities of using materials such as adobe, papercrete, styrofoam and plastics.
