If you’ve purchased a miter saw in the earlier number of decades, you might have discovered the LED “laser” that arrived with it. The aim was to clearly show wherever on the piece the observed was likely to cut. But above a year or two, you could have observed the laser to have drifted or skewed into a crooked line. [Fisher] determined that his right after-current market laser was not totally accurate enough and extra a shadow line as an alternative. (Movie, embedded underneath the crack.)
The blade has a thickness (regarded as kerf), and with a laser to a person facet, you can only properly slice on a single aspect of the line. A shadow line works in a different way. By shining a line at the prime of the blade, you get a mark exactly where the blade will slice exactly. You can also see your marks as the laser does not shine above them. Formerly, [Fisher] experienced tried using to use LED strips, but right after a remark advised it, he located a sewing light-weight on a gooseneck. It labored excellent as a tiny compact gentle fitting the blade housing. Right after some quick modifications, hot glue, and duct tape, the light was set up, and the wires were being routed when however enabling the saw its full vary of movement.
The result is extraordinary, with a obvious shadow on even darker hardwoods. Just the few check cuts he made seemed entirely correct. Of system, you can generally go deeper down the gap of accuracy and measurement. But all round, [Fisher] has a good little mod that speeds up his workflow extra precisely.
