Rant: Old timer in Pittsburgh showed me up on a tape measure trick
I was on a job in Pittsburgh last spring, hanging 12-foot boards in a hallway with a bunch of angles. This guy, must have been 60 years old, comes over and watches me measure, mark, and cut each piece one at a time. He just shook his head and said 'son, you're wasting half your day.' Then he showed me how to mark multiple studs at once with a chalk line and a speed square, cutting all the boards in one stack. I felt like an idiot but honestly it saved me about 45 minutes on that room alone. He didn't even say much else, just walked off to his own work. Has anyone else had a random stranger on site teach you something that simple but game-changing?
