ABSTRACT:
The miter box has a flat rectangular base and a pair of upraised, parallel and spaced-apart longitudinal guide rails. One of the guide rails is rigidly secured to the base, while the other can be laterally adjusted to guide the support plates of different makes of circular saws. A work piece guide bar is provided, being pivotally secured to the base at one of its ends and provided with a bolt-and-nut arrangement engaging an arcuate slot in the base, for releasably locking same in a desired angular position in relation to the path of the saw. A portion of a depression made in the base between the guide rails is occupied by a removable plank for receiving saw-cuts made by the specific saw used with the miter box.
