ABSTRACT:
A portable sawmill is provided in which a rigid straight channel support is placed on a floor or on the ground with one end slightly elevated. A pair of longitudinally spaced log supports are mounted in the channel piece at a distance corresponding to the length of a log to be placed thereon. A carriage with rollers is mounted to ride along the upturned edges of the channel piece and is adapted to roll by gravity from the elevated end of the channel piece to the lower end. The carriage includes a bandsaw driven by a low horse power motor and is equipped with a release mechanism for automatically disengaging the drive between the motor and the saw at the end of a cutting stroke. A jacking mechanism and adjustable shelves on the log supports are included for raising the log to a new height after each cut.
