JT...was just wondering what the deepest cut you've made with your SB? I've long ago changed over to the way you explained it to me (sharp tools, back gear, low gear). With mild steel I usually cut .060 but tonite I was in a hurry to turn down some hubs from 4" dia X 1 1/2" thick flame cut blanks from plate. The ol' SB9 will easily cut .090 DOC but it's grunting pretty good. I'm thinking you take deeper cuts than this so what is the limit you've found? I'm not sure that I've got the tool sharpening down to go much further. Thanks!
