Abstract:
1. A chain saw arrangement for cutting flat sides on an elongated round log or timber having a longitudinal axis, comprising: a chain saw housing at a first end of said chain saw; an elongated chain/blade supporting frame extending from said chain saw housing; a multi-tooth chain/blade movably supported in a peripheral track on the periphery of the elongated frame; a substantially L-shaped support bracket having a first and a second side that extend parallel to the length of the chain saw, the first side adjustably mounted to the supporting frame and the second side extending, substantially perpendicularly from the first side; a shoulder formed in the support bracket along the entire intersection of the first side and the second side that provides clearance for the movement of the multi-tooth chain/blade to move along the periphery of the elongated frame; and wherein the support bracket is vertically adjustable to control the depth of the blade teeth on the multi-tooth chain/blade extending out of the shoulder, beyond the second side of the support bracket and into the log or timber being worked and wherein the second side of the bracket provides support to the chain saw to permit sideways guided movement of the chain/blade along the longitudinal axis of the log or timber to cut flat sides into the log or timber.
