Abstract:
A cutting saw, comprising:a motor that induces rotary motion in a shaft;a plate that is mounted to the shaft so that the shaft can be held stationary relative to the plate on all axes except a longitudinal axis of the shaft, whereby the shaft can be freely rotated about the longitudinal axis of the shaft;an elongated saw-bar mounted to the plate, the saw-bar having a perimeter;a cutting-chain entrained about the perimeter of the saw-bar and about the shaft so that rotation of the shaft induces rotary motion of the cutting-chain about the perimeter of the saw-bar, the cutting-chain including at least one tooth that is capable of removing solid material;a base that is slidably mounted to the plate to permit the plate to move relative to the base between a first position and a second position; anda depth stop that limits movement of the plate relative to the base to a plurality of third positions that are between the first and second positions;wherein the base encloses the saw-bar and the cutting-chain in the first position, and wherein the base encloses only a portion of the saw-bar and the cutting-chain in the second position.
