A removable bottom panel is mounted to the body portion beneath the floor in alignment with the cylindrical guide. The reinforcer loader is inserted into the reinforcer loader receptacle support so that the loaded stack of reinforcing rings are positioned upon the removable bottom panel directly beneath the punching ram. The punching ram is forced downwardly through the stack of reinforcing rings and has an enlarged punching tip that passes through the central apertures in the reinforcing rings.
