    Damn ! The amount of oxygen used to cut that shaft into the pieces shown has to be unbelievable ! (Oxygen Lance video)

      I've cut 4140PH 5" in diameter with abrasive cut off wheels a number of times when I was younger. It was slow but effective, no broken wheels... Used wheels like the below in a 9" grinder. I'd score around the circumference to get a clear groove to follow by eye and then cut the majority of the way through on one side and rotate 90 to finish up.

      These days I'd probably torch it and, if I needed a clean face, hard turn / part in a lathe. Feels faster and quieter than running the angle grinder and I don't have a water jet!
