If you’ve purchased a miter noticed up to now few years, you may need seen the LED “laser” that got here with it. The objective was to indicate the place on the piece the noticed was going to chop. However over a yr or two, you may need discovered the laser to have drifted or skewed right into a crooked line. [Fisher] determined that his after-market laser wasn’t solely correct sufficient and added a shadow line as a substitute. (Video, embedded beneath the break.)
The blade has a thickness (referred to as kerf), and with a laser to 1 facet, you possibly can solely precisely minimize on one facet of the road. A shadow line works in another way. By shining a line on the prime of the blade, you get a mark the place the blade will minimize exactly. It’s also possible to see your marks because the laser doesn’t shine over them. Beforehand, [Fisher] had tried to make use of LED strips, however after a remark instructed it, he discovered a stitching gentle on a gooseneck. It labored nice as a small compact gentle becoming the blade housing. After some fast modifications, sizzling glue, and duct tape, the sunshine was put in, and the wires have been routed whereas nonetheless permitting the noticed its full vary of movement.
The result’s spectacular, with a transparent shadow on even darker hardwoods. Simply the few check cuts he made appeared solely correct. Of course, you possibly can at all times go deeper down the opening of accuracy and measurement. However general, [Fisher] has an ideal little mod that hastens his workflow extra precisely.
