For the greatest accuracy in milling with Alaskan Mk III or Small Log Mill, the initial cut must be smooth and level. A set of Slabbing Rail Brackets helps make the ideal guide for the mill to follow. Simply attach to 2 lengths of 2" x 4" timber (not included) to complete the guide rail system. Also includes screws and double-headed forming nails for securing the slabbing rail system to the log.
