Abstract: A machine including two hollow members, each divided into two chambers with a diaphragm being the divider between the chambers, one of the chambers of each of the devices adapted to receive fluid to push the diaphragm in a direction to force abrasive material adapted to be held in the second chamber through an orifice extending outwardly from the second chamber, and a baffle positioned in the orifice to prevent expansion of the diaphragm through said orifice and to direct the flow of abrasive material into said second chamber when said hollow members are positioned to cooperatively move abrasive material through a workpiece held between the orifices of said members.
