A wooden wine barrel has one end removed, and is supported by and rotated by power driven support wheels. A router type cutter head extends into the barrel on an inner end of an arm which is pivoted at its outer end so that the cutter head can follow the contour of the barrel, and means to move the barrel longitudinally with respect to the arm (or vice versa) to effect relative longitudinal movement between the arm and barrel.
