Apparatus for accurately cutting logs and large timbers at selected angles with a chain saw is disclosed. The invention includes a base framework which works in combination with a support table. The base framework includes vertical rods mounted to the base framework. The bar of the chain saw is secured to guides which slide up and down on the rods. The chain saw and base framework combination are pivotally secured to the support table such that the chain saw blade can be positioned at various angles with respect to the log or other material being cut. Once the angle has been selected, the chain saw and base framework combination are secured to the support table such that the angle at which the logs are cut will remain constant as the saw is operated. One embodiment includes means for counter balancing the chain saw weight to aid in operation of the saw.
