I messed up a staircase stringer so bad I had to scrap the whole thing
I was working on a custom staircase in a house over in Arlington back in March, and I got too confident with my layout. I marked the first stringer in about 20 minutes, cut it out with my circular saw, and then realized the rise was off by nearly a half inch on the top step. Turned out I used the wrong multiplier when I was doing my math, and I didn't double check before cutting. I had to toss that whole stringer and start fresh, which cost me an extra $40 in lumber and about two hours of time. My boss walked up right as I was throwing the scrap in the dumpster and just said "well, that's a learning experience." Now I always verify my layout on the framing square before I make any cut, and I write the numbers right on the wood so I can see them. Has anyone else had a stringer layout fail that forced you to scrap a whole piece?
