Abstract
This disclosure is directed to a miter gauge and methods of use thereof. Generally, this disclosure is related to a miter bar of a miter gauge that includes at least one spacer member which applies pressure to a side of a channel defined within a worktable. The application of this pressure by the at least one spacer member enables the miter bar to remain in a substantially constant position between the first side and second side of the channel and reduces the degree of play between the miter bar and the first and second sides of the channel. Retainer members are provided on a bottom of the miter bar to aid in preventing the miter bar from lifting vertically out of the channel during use.
Claims27
A tool for material processing comprising:
- an elongate body having a top and an opposed bottom, and a first side and a second side extending between the top and bottom;
- and
- at least one spacer member provided on the first side of the body;
- wherein the at least one spacer member is located within a slot defined in the first side of the body;
- wherein the at least one spacer member includes:
- an outer wall which is convexly curved;
- a first wall which meets a first end of the outer wall at a first corner;
- a second wall which meets a second end of the outer wall at a second corner;
- wherein the first wall and second wall angle inwardly and rearwardly away from the first corner and the second corner and towards one another;
- and
- an inner wall which extends between the first wall and the second wall;
- wherein the outer wall, the first wall, the second wall, and the inner wall bound and define a central space;
- wherein the inner wall is located within the slot and the outer wall extends at least partially outwardly from the slot and beyond the first side of the body;
- wherein the outer wall is movable relative to the inner wall and thereby relative to the first side of the body between a first position and a second position;
- and
- wherein when in the first position, the outer wall is located further outwardly from the first side than when in the second position.
A method of working a surface of a workpiece comprising:
- inserting a bar between a first side and a second side of a channel defined in a worktable;
- providing at least one spacer member on a first side of the bar, wherein the at least one spacer member is located within a slot defined in the first side of the bar and wherein the at least one spacer member includes an outer wall which is convexly curved, a first wall which meets a first end of the outer wall at a first corner, a second wall which meets a second end of the outer wall at a second corner, wherein the first wall and second wall angle inwardly and rearwardly away from the first corner and the second corner and towards one another, and an inner wall which extends between the first wall and the second wall, wherein the outer wall, the first wall, the second wall, and the inner wall bound and define a central space, and wherein the inner wall is located within the slot and the outer wall extending at least partially outwardly from the slot and beyond the first side of the bar, wherein the outer wall is movable relative to the inner wall and thereby relative to the first side of the bar between a first position and a second position;
- applying a force to the first side of the channel with the outer wall of the at least one spacer member;
- holding the second side of the bar in contact with the second side of the channel;
- operatively engaging a workpiece with the bar;
- moving the bar longitudinally within the channel while holding the second side of the bar in contact with the second side of the channel;
- contacting the workpiece with a working element on the worktable;
- and
- working a surface on the workpiece with the working element.
