Abstract
Abstract The disclosure is of a guide which may be fitted to the cutting bar of a hand-held chainsaw, in such a manner that the chainsaw and guide may be used together for the purpose of sawing dimensioned lumber from logs. The guide is adaptable to any chainsaw of the hand-held variety. The advantages of the milling guide of the invention resides in its ability to guide the kerf of the chainsaw with relative ease, and its ability to provide leverage support to help press the cutting teeth of the chainsaw into the log, and its simplicity of operation and portability compared to other devices of this type.
