Am I the only one who just found out my laser level was lying about being level?
I picked up a cheap laser level at a pawn shop in Reno about two years ago and never thought twice about it. Last Tuesday I was framing a small closet and my corners kept coming up off by about a quarter inch, which didn't make sense since I checked everything with the laser first. I finally laid a 4 foot spirit level right next to the beam and the bubble told me a different story, so I tested the laser on a known flat table and it was off. Turns out the thing needed calibrating the whole time and I had been trusting it on maybe a dozen jobs. How often do you guys check your lasers, and is there a quick way to test one in the field?
