  • First fully adjustable sawmill with precise rapid cut band saw
    Patent number: 5035166
    Abstract: A sawmill includes a band saw mounted on a trolley. The trolley carries the band saw back and forth across the length of a log to cut it into boards. A log supporting table is adjustable to accomodate logs of various size. The trolley rails descend incrementally after each cut to reposition the band saw blade for the next cut. The length of each increment, or board thickness, is user selectable by way of an indexable detent bar and limit switch combination. The thickness across the board is held uniform by a pressurized bellows that maintains the proper blade strain in the band saw blade.
