ABSTRACT:
A compound miter jig apparatus includes a base unit and a plurality of connectors for connecting the base unit to an article to be cut. A pair of pivot support assemblies arc connected to the base unit. The pivot support assemblies are spaced apart from each other on the base unit and include longitudinally adjustable first pivot elements. A bearing block assembly is supported by the first pivot elements and is located between the first pivot elements. The bearing block assembly includes a pair of second pivot elements in contact with the first pivot elements. The bearing block assembly also includes a shaft bearing assembly. A shaft assembly is supported by the shaft bearing assembly. The shaft assembly includes a chain-saw-connector assembly. An adjustable tilt-lock assembly is supported by the base unit and is connected to the bearing block assembly for locking the bearing block assembly at a predetermined angular tilt. The base unit includes a component-support portion which supports the pair of pivot support assemblies and the lock block and may include a base extension portion which extends away from the component-support portion.
