Abstract
A portable saw guide and T-square and method of use where an accurate and straight saw cut is desirable. The T-square saw guide has an alignment arm and a flexible guide arm which can be quickly and accurately secured to a work piece such as a sheet of plywood by a clamping mechanism in order that a worker may use a guide edge of the T-square to accurately maneuver and guide a saw along a desired course despite variations in the surface of the work piece. The guide arm forms a flush linear contact between a surface of the workpiece and the saw guide to compensate for any non planar irregularities such as a bow, sag or warp in the work piece to cause continuous contact between the saw being guided along the guide edge of the T-square to produce a straight cut along the work piece.
Claims10
A portable saw guide comprising:
- a guide arm having a near end and a far end;
- an alignment arm attached to the near end of the guide arm, the guide arm and alignment arm defining a first plane;
- a clamping mechanism extending adjacent the guide arm and being separately attached to the near and far ends of the guide arm;
- and
- wherein the guide arm has a guide edge flexible along a second plane substantially perpendicular to the first plane.
A portable saw guide comprising:
- an elongate base arm having a first and second end defining an x axis;
- an elongate guide arm having a first and second end defining a y-axis, the base arm and guide arms being connected at a joint defining a z axis, with the respective x and y axis defining an x-y plane and the z and y axis defining a y-z plane perpendicular to the x-y plane;
- an elongate clamping device having a first and second end connected with the first and second end of the guide arm respectively, and
- wherein the guide arm is rigid in the x-y plane and flexible along the y-z plane perpendicular to the x-y plane.
A method for cutting a work piece using a portable saw guide, the method comprising the steps of:
- providing a guide arm having a near end and a far end;
- attaching an alignment arm to the near end of the guide arm, the guide arm and alignment arm defining a first plane;
- attaching a clamping mechanism extending adjacent the guide arm and being separately attached to the near and far ends of the guide arm;
- and
- providing the guide arm with a flexible guide edge variably movable with respect to the clamping mechanism along a second plane substantially perpendicular to the first plane.
