Used oxy-acetylene, oxy-propane, oxy-gasoline, carbon arc, and plasma cutting torches. Performed straight line cuts, 30 and 45 degree bevel cuts, and hole cuts. I am not flawless at creating hole cuts, I can be off by 1/4 inch to 3/8 inch somewhere within the hole cut or the hole cut is almost fully uniform but not quite fully uniform in shape. Not always able to consistently maintain a flawless hole cut.
