Tool: Magnetic Straightedge Shop Now
Manufacturer: Lee Valley
MSRP: $7.50
Don’t have a drafting table? Can’t draw freehand to save your life? Here’s a tool from Lee Valley that lets you easily make isometric shop sketches.
The tool has two parts: a standard 12″ ruler with a matte finish and an innovative black straightedge. Seven slots are milled into the back of the straightedge corresponding to commonly used angles (30°, 45° and 60° in both directions, plus 90°). Two rare earth magnets embedded in each slot hold the ruler in place at any of these angles, like a T-square with an adjustable arm. A small amount of play between ruler and slot makes the angles only accurate to within 2°, but that’s OK for a sketch. The ruler can also be attached parallel to the straightedge.
While playing around with this new tool, we found that it’s best to tape the paper to a 9″ x 12″ piece of 1/4″ hardboard and turn the tool over. The paper stays put and the board provides a reference edge.
Here are some supplies and tools we find essential in our everyday work around the shop. We may receive a commission from sales referred by our links; however, we have carefully selected these products for their usefulness and quality.
