My father-in-law has worked for decades in the oil and road industries. He currently runs a research lab at Iowa State University. He's pretty good at what he does, and I believe him when he says he has done something in the past. I asked him if he had a waterjet table at his shop and he said they don't. He then went on to explain how they used to cut 3/8" steel in the field back at the oil wells. They would use a 2500 PSI pressure washer and garnet sand poured into the stream after coming out of the nozzle. A far cry from the 9000 PSI they use to cut bridges, but still in the realm of feasible. They could cut steel with no problem in a matter of minutes this way. He said the cut was about 1/4" wide, obviously much more coarse than we're used to, but still an intriguing idea. My pressure washer is only 1300 PSI, but I know a guy. . . .
Has anyone tried this?
