Abstract

A work piece guide assembly is for use with a table saw having a fence that defines an elongated slot. The work piece guide assembly includes a body having a mating component configured to be received in the elongated slot of the fence. A handle for manipulating the guide assembly is supported by the body. The work piece guide assembly includes an arm having a first end portion pivotably mounted in relation to the body and a second end portion defining a work piece contact surface. A roller is rotatably connected to the second end portion of the arm.

Claims (14)

1. A method of guiding a work piece on a table assembly with a guide assembly, with (i) the table assembly including a base defining support surface, a saw mechanism supported by the base, and a fence supported by the base, the fence defining an elongated slot, and (ii) the guide assembly including a body having a mating component received in the elongated slot of the fence, a handle supported by the body, an arm pivotably connected in relation to the body and defining a contact surface, and a roller rotatably connected to the arm, comprising:

advancing a work piece on the support surface along the fence and under the arm of the guide assembly in a cutting direction;

positioning the roller in contact with a top surface of the work piece as the work piece is being advanced under the arm, the arm being oriented so that the contact surface is positioned above the top surface of the work piece while the roller is in contact with the top surface of the work piece;

maintaining the guide assembly supported on the fence in a fixed position while the roller is in contact with the top surface of the work piece;

further advancing the work piece on the support surface until a trailing end of the work piece moves past the roller and the roller becomes spaced apart from the top surface;

pivoting the arm downwardly until the roller contacts the support surface and the contact surface is positioned facing the trailing end of the work piece after the trailing end of the work piece has moved past the roller; and

moving the guide assembly in relation to the fence in the cutting direction after the roller is positioned in contact with the support surface and the contact surface is positioned facing the trailing end of the work piece so as to push the contact surface against the trailing end of the work piece and cause the work piece to further advance on the support surface,

wherein the contact surface is positioned in front of the roller relative to the cutting direction so that the contact surface is moved into engagement with the trailing end of the work piece when the guide assembly is moved in the cutting direction with the roller positioned in contact with the support surface.

2. The method of claim 1 , wherein:

the mating component of the body is located in the elongated slot of the fence, and

the mating component is advanced within the elongated slot of the fence when the guide assembly is moved in relation to the fence.

3. The method of claim 1 , further comprising:

cutting the work piece with the saw mechanism while the roller of the guide assembly is biased against a top surface of the work piece, and

cutting the work piece with the saw mechanism while the contact surface of the arm is positioned in contact with the trailing end of the work piece, and the roller is positioned in contact with the support surface.
