I need to make a short run 7/8" round punch. I figured I would get some oil or water hardening drill rod to make the male part of the punch. Maybe some oil or water hardening flat stock to make the female part of the punch. I also thought a good way to do the female side of the punch was to use a 7/8" drill bushing. Seems to me it would work if I surface grind it so the ID edges have no chamfer. From what I can gather oil hardening material is better. So my questions are:
What is the procedure for hardening this material?
What type of oil do I use?
From what I can gather a forge is better that a torch. Unfortunately I don't have a forge will a torch work OK? Again, this is a short run (30 pieces) punch for some stainless steel screen. Wire diameter of the screen is .016"
