Miter Saw with Adjustable Fence

Abstract

A miter saw includes a base, a turntable rotatable in relation to the base and including a work piece support surface, a support assembly attached to the turntable, and a saw assembly attached to the support assembly and configured to cut a work piece supported on the turntable. A fence assembly includes an elongate fence body that extends along a first axis. The elongate fence body is supported by the base and positioned over the turntable. The fence body has a first connecting structure, and a fence insert defining an elongate work piece abutment surface and having a second connecting structure. The fence assembly is positionable in a first configuration and a second configuration. In the first configuration, the second connecting structure cooperates with the first connecting structure to secure the fence insert at a first position in relation to the fence body. When the fence assembly is positioned in the second configuration, the second connecting structure cooperates with the first connecting structure to secure the fence insert at a second position in relation to the fence body. A second axis intersects the first axis in a perpendicular manner. When the fence insert is secured at the first position, the elongate work piece abutment surface is positioned to intersect the second axis at a first point. When the fence insert is secured at the second position, the elongate work piece abutment surface is positioned to intersect the second axis at a second point, and the first point is offset from the second point along said second axis.
