ABSTRACT:
A simplified miter box suitable for use with a conventional carpenter's saw comprises upper and lower relatively rotatable platforms with a pair of radially spaced, upstanding saw guide posts fixed to the lower platform. Each post has a vertical, upwardly open saw guide slot extending therethrough. The slots are radially aligned with each other. The upper platform rotates about the first post and has an outer circular edge captured for sliding movement by a complementary groove in the second post. An upstanding workpiece support is fixed to the upper platform, and an angular scale alignable with a reference mark of the lower platform is inscribed on the upper platform outer edge.
