The tube alignment on unit 3 at the Cayuga plant was off by a quarter inch and the old guy called it in 1989
I was doing a walkdown at the Cayuga generating station last Tuesday and noticed the bottom row of tubes sit a hair off center compared to every other pass. An operator there told me a fitter flagged it during the original erection back in 1989 and they just left it because it still drums fine. Any of you ever run into a job where the old hand's call from decades ago still holds up?
