Just saw this on you tube and thought it might have potential.
Only in rare instances Roger. The cut through the base is normally enough on this type sled and my one runner sled uses the edge of the cut but if you couldn't register the mark against those it might have some application. What impressed me was repurposing the lasers off old tools the most, I hadn't thought of that. I can see the idea being useful on a drill press where you use 2 of the lasers and form crosshairs. I also have an over the saw blade dust collection plan in mind and it would be easy to add a laser to that to help with lining up rip cuts at times.just watched it and wonder does it do anything that the existing saw cut in the sled does not?
