If you’ve purchased a miter saw in the earlier few many years, you could have seen the LED “laser” that came with it. The intention was to demonstrate exactly where on the piece the noticed was going to slice. But above a yr or two, you might have found the laser to have drifted or skewed into a crooked line. [Fisher] made the decision that his soon after-current market laser wasn’t fully correct ample and extra a shadow line as a substitute. (Movie, embedded under the crack.)
The blade has a thickness (regarded as kerf), and with a laser to just one facet, you can only accurately slice on a single facet of the line. A shadow line performs differently. By shining a line at the best of the blade, you get a mark exactly where the blade will slice specifically. You can also see your marks as the laser doesn’t shine around them. Beforehand, [Fisher] had experimented with to use LED strips, but following a remark suggested it, he found a sewing light on a gooseneck. It worked good as a compact compact light fitting the blade housing. Just after some speedy modifications, incredibly hot glue, and duct tape, the light was installed, and the wires were routed while still enabling the noticed its full selection of motion.
The end result is amazing, with a crystal clear shadow on even darker hardwoods. Just the handful of exam cuts he produced appeared fully precise. Of course, you can constantly go further down the gap of accuracy and measurement. But in general, [Fisher] has a wonderful small mod that speeds up his workflow extra correctly.
