ABSTRACT:
A miter attachment for use with a portable electric circular saw. This miter attachment has a smooth upper platform secured to rails positioned at 90.degree., and at 45.degree. right and left which are also secured to the base. A portable saw is placed on the upper platform with the circular blade in the marked pre-cut saw groove for true miter cutting. The saw shoe is fixed in position by clamps and the user releases the elevation knob on the saw, allowing it to move freely up and down on a pin hinged to the saw shoe. A plunge cut is achieved as the saw is lowered and the blade passes through the workpiece, placed and held against the rail between the upper platform and the base.
