The week my framers used a laser level that was clearly possessed...
Last Tuesday in Eugene I watched three grown men argue with a laser level that was bouncing the line all over the foundation. Turns out a spider had built a web right over the sensor and was throwing the beam off by almost 4 inches. Has anyone else had a tool go haywire over something dumb like that?
Had a circular saw that kept tripping the breaker once. Took me an hour to realize a piece of sawdust was stuck in the safety switch. Tapped it out with a screwdriver and it worked fine after that.
