I used to think you could eyeball the ladder pipe angle on a cutterhead dredge
For years on the Mississippi, I'd just set it by feel and watch the spoil color. Then we hit a rock shelf near Baton Rouge and bent a drive shaft because the angle was too steep. The repair bill was over 15 grand. Now I use the inclinometer every single time before we start cutting, no exceptions. Anyone else get burned by skipping a simple check like that?

Yeah, the part about chewing up the cutter teeth in twenty minutes really hits home. I read a case study from a dredging safety group that said most mechanical failures start with skipping the basic instrument checks, just like rosew37 said about hard lessons. They had a whole section on how even a few degrees off can put crazy stress on parts you don't even see. It's wild how a five second look at a gauge can save you from a week of downtime and a huge bill.

Yeah, that'll make you change your tune fast. Always figured the old hands knew best with the eyeball method too, until a similar thing happened on a gravel bar up north. Not a bent shaft, but we chewed up a set of cutter teeth in about twenty minutes. Now that little digital gauge is my best friend before the pump even turns over.
