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.
Claims11
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 along the guide arm and being fixedly attached tip the near and far ends of the guide arm;
- and
- wherein between the near and far ends the guide arm has a central guide edge freely flexible along a second plane substantially perpendicular to the first plane.
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;
- the guide arm has a guide edge flexible along a second plane substantially perpendicular to the first plane;
- the clamping mechanism further comprises a housing supporting an adjustment lever adjacent the near end of the guide arm, and a clamp adjacent the far end of the guide arm, the adjustment lever and clamp being connected by a clamping rod extending through a passageway in the housing;
- and
- wherein the housing is a rigid member connected to the guide arm at the near and fat ends thereof and a spacing mechanism is provided intermediate the near and far ends and between the housing and the guide arm to provide a variable spacing therebetween.
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;
- the guide arm is rigid in the x-y plane and flexible along the y-z plane perpendicular to the x-y plane;
- and
- wherein the guide arm has a middle portion which can be variably spaced along the y-z plane from the elongate clamping device.
