Abstract

A miter saw including a base having a support surface for supporting thereon a workpiece and a turntable mounted on the base for rotation about a generally vertical axis. A support is mounted on the turntable for movement therewith and a saw arm is mounted on the support for pivotal movement about a horizontal bevel angle axis such that the saw arm is adjustable to cut the workpiece at a selected bevel angle, and the saw arm being mounted on the support for pivotal movement about a second horizontal axis perpendicular to the bevel angle axis to allow movement of the saw arm between cutting and non-cutting positions. A reversible fence is removably connected to the base to support the workpiece on the base. The fence has opposite ends such that one end has a vertical edge portion for supporting the workpiece during conventional miter cutting of the workpiece and the other end has an angled edge portion for supporting the workpiece during compound miter cutting of the workpiece.

Dependent claims

A miter saw comprising:

a base having a workpiece support surface for supporting a workpiece;
a turntable supported by the base for rotation about a generally vertical axis;
a saw arm having a vertical position and being supported by the turntable for pivotal movement about a horizontal bevel angle axis such that the position of the saw arm is adjustable from the vertical position and with respect to the base workpiece support surface to facilitate cutting of the workpiece at a selected bevel angle, and the saw arm being mounted for pivotal movement about a second horizontal axis perpendicular to the bevel angle axis between cutting and non-cutting positions;
and
a reversible fence having a workpiece support surface and including a clamp mechanism for removably connecting the reversible fence to the base to support the workpiece on the base, and the reversible fence having a first end including a vertical edge and having a second end including an angled edge and the fence being positionable in a first position when the saw arm is in the vertical position such that the vertical edge is adjacent to the cutting path of the saw blade for supporting the workpiece during conventional miter cutting of the workpiece and the fence being end-for-end reversible to a second position wherein the angled edge is adjacent to the cutting path of the saw blade for supporting the workpiece during compound miter cutting of the workpiece.

2 more elements

An elongated, removable workpiece support fence for use on the base of a compound miter saw to support a workpiece on the base, the miter saw having a fence support mounted on the base and a saw blade for cutting the workpiece, the saw blade defining a cutting path and the workpiece support fence comprising:

a first end having a vertical edge for supporting the workpiece when the workpiece support fence is in a first position such that the first end is adjacent the cutting path of the saw blade;
a second end having an angled edge for supporting the workpiece when the workpiece support fence is in a second position such that the second end is adjacent the cutting path of the saw blade;
and
means for removably connecting the workpiece support fence to the base such that the fence is positionable in a first position when the saw arm is in the vertical position such that the vertical edge is adjacent to the cutting path of the saw blade for supporting the workpiece during compound miter cutting of the workpiece and the fence being end-for-end reversible to a second position wherein the angled edge is adjacent to the cutting path of the saw blade for supporting the workpiece during compound miter cutting of the workpiece.

1 more element

A miter saw comprising:

a base having a workpiece support surface for supporting a workpiece and having a fixed fence including a vertical support surface;
a turntable supported by the base for rotation about a generally vertical axis;
a saw arm having a saw blade and being supported by the turntable for pivotal movement about a horizontal axis between cutting and non-cutting positions to define a cutting path for the saw blade;
and
a reversible fence having a workpiece support surface and having a first end and a second end;
and
a clamp mechanism removably mounting the reversible fence to the base such that the reversible fence is positionable in a first position wherein the reversible fence support surface is substantially in the same plane as the fixed fence support surface and the first end is adjacent the cutting path of the saw blade, and such that the reversible fence is end-for-end reversible to a second position wherein the reversible fence support surface is substantially in the same plane as the fixed fence support surface and the second end is adjacent the cutting path of the saw blade.
