Workshop accuracy begins with a benchmark straight edge as a surface reference. These Canadian-made precision steel straight edges are ground flat over the entire length on both edges, the 610(24") length to within 0.025mm and the 915mm(36") length to within 0.038mm. All have been stress relieved to remain true under temperature variation. Useful for checking whether surfaces are flat or straight, they are 38mm wide and easily stand on edge unsupported, leaving both hands free for precise measurement or tool adjustment. All have hang holes, allowing storage on a nail or hook.
915mm(36") Steel Straight Edge
Great for long-bed jointer and larger machine set-up, the 915mm straight edge is a good master shop reference. Weighing a substantial 2.6kg, it is 9.5mm(3/8") thick. The linished sides give a textured surface that makes the straight edge easier to grip with confidence.
