Abstract: A chain saw gauging attachment having a fitting at one end adapted to be received under an existing nut on an existing stud of a chain saw, a rod extending outwardly from the fitting, means for firmly attaching the rod to the fitting, and an indicator which is slidably affixed to the rod and adapted to be fixed in predetermined positions. The fitting of the gauging attachment may be provided with a rotating means which permits the gauging attachment to be swung to the rear of the chain saw and away from the working area when not in use. When mounted, the gauge rod extends along the length of the work piece of a log to which is to be cut, and the indicator of the gauge rod enables the user to fix by sight the place on the log where the next cut is to be made. The gauge rod is slender and resilient whereby it will spring back to its original shape if accidently flexed.
