WoodRiver Salt and Pepper Mill Grinder Kits are made with quality ceramic mechanisms that ensure a perfect grind and are available in three shaft lengths - 4", 6", and 8" - to provide flexibility in sizing. Adjust from extra coarse to an extra fine grind by turning the knob on top of the mill. Use our WoodRiver Bushings (sold separately) to make turning your mill’s body easy. Bushings can be mounted on any standard pen mandrel to turn the 3-3/4" mill body or mount between centers using a 4-jaw chuck to turn the 5-3/4" or 7-3/4" mill body. Wood or man-made blank for the body sold separately. Kit comes complete with easy to follow instructions for assembly and installation and all the hardware to make one Salt Mill or one Pepper Mill.About Us: Founded in Boston in 1928, Woodcraft's operations were moved to Parkersburg, West Virginia in 1989.
