re: Cutting steel for plane blades

George..... I tried it and it worked but it scared me some so I'm not doing it. Better safe than sorry. What bothered me is that I'm pushing the metal into the spinning disc on the TS and it all counts on my ability to hold it while pushing it thru. If I misjudge the heat build up and can't hold it then I have a flying blade!! No way Jośe! 
I'm doing it with my hand grinder and touching up on the bench grinder at the moment. When cutting it with my hand grinder I can clamp it down on my workmate.
Way way safer!!
