Abstract: A lathe steady rest has a frame adjacent an axis about which a lathe rotates a workpiece, a pair of arms pivotal on the frame about arm axes parallel to the workpiece axis and having outer ends radially displaceable relative to the workpiece axis, and a slide displaceable radially of the workpiece axis on the frame and having an outer end turned toward the workpiece. The outer ends are angularly spaced about the axis. Respective rollers rotatable on the outer ends about roller axes parallel to the workpiece axis radially engage the workpiece. Respective caps mounted on the arm outer ends over the respective rollers have passages with outer ends directed radially inward against the workpiece adjacent the respective rollers. A fluid is supplied under pressure to the passages to flush particles from the workpiece. The chamber allows the respective cap to change position without losing pressure in its passages.
