If you’ve purchased a miter noticed up to now few years, you might need seen the LED “laser” that got here with it. The aim was to indicate the place on the piece the noticed was going to chop. But over a 12 months or two, you might need discovered the laser to have drifted or skewed right into a crooked line. [Fisher] determined that his after-market laser wasn’t totally correct sufficient and added a shadow line instead. (Video, embedded under the break.)
The blade has a thickness (generally known as kerf), and with a laser to at least one aspect, you may solely precisely minimize on one aspect of the road. A shadow line works otherwise. By shining a line on the high of the blade, you get a mark the place the blade will minimize exactly. You may also see your marks because the laser doesn’t shine over them. Previously, [Fisher] had tried to make use of LED strips, however after a remark prompt it, he discovered a stitching mild on a gooseneck. It labored nice as a small compact mild becoming the blade housing. After some fast modifications, scorching 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. Just the few take a look at cuts he made appeared totally correct. Of course, you may at all times go deeper down the hole of accuracy and measurement. But total, [Fisher] has a fantastic little mod that hurries up his workflow extra precisely.
