I had the oppertunity to go watch the Guntner's at a demo in Pery, OK last month. Chad Guntner was holding his punch with a set of tongs, I was talking to him about why he did it that way, and he said that you can keep your hands away from the work and it saves room on tooling. I liked the idea and took it and ran with it. Now I'm having trouble, I'm using 01 tool steel and I think I heat treated everything right. I heated to around 1600 degrees, then quinched it oil. Then I bake it in the oven at 450 degrees, until the steel turned a straw color. I was pretty excited to use them today. When I started to use them is when I ran into trouble, they broke in the troat. How might I prevent this from happening again? I have put the rest aside until I can come up with a solution, or before I hurt myself. Any help will be greatly appreciated.
