Crown molding cutting jig

A workpiece support fence mounting arrangement for mounting a workpiece support fence to a miter saw, the workpiece support fence having a first wall having a first workpiece support surface and a second wall extending forward from the first wall, the miter saw having a vertical fence having a first mounting aperture through the vertical fence, the workpiece support fence mounting arrangement comprising:

• a back plate configured to attach the workpiece support fence to the miter saw, the back plate having a first horizontal slot and a first vertical slot, the back plate having a front side facing the workpiece support fence in an assembled state and an opposite rear side facing away from the workpiece support fence in the assembled state, the rear side facing the vertical fence when mounted to the miter saw;
• a first connector attachable to the back plate within the first vertical slot configured for securing the workpiece support fence to the back plate for vertically adjustably positioning the workpiece support fence relative to the back plate;
• a second connector extending rearward from the rear side of the back plate for extending through the first mounting aperture in the vertical fence, the second connector adjustably positionable within the first horizontal slot to allow for adjusting the horizontal position of the back plate relative to the vertical fence of the miter saw when mounted thereto.

A jig for supporting a piece of crown molding to be cut by a miter saw having a vertical fence having a first mounting aperture through the vertical fence, the jig comprising:

• a workpiece support fence portion having a first wall having a first workpiece support surface and a second wall extending forward from the first wall;
• a first workpiece support block assembly removably attachable to the second wall, the workpiece support block assembly configurable relative to the workpiece support fence portion to selectively provide:
• in a first configuration, a third workpiece support surface that extends at a first angle relative to the first workpiece support surface, the first angle is non-perpendicular and non-parallel orientation relative to the first workpiece support surface;
• and
• in a second configuration, a fourth workpiece support surface that extends at a second angle relative to the first workpiece support surface, the second angle is non-perpendicular and non-parallel relative to the first workpiece support surface, the second angle is different than the first angle.
