    I can definitely can understand your views John when are making tools to sell. I think if you are making tools to use in your own shop then playing with salvaged steel can add to the learning experience. I really enjoy these projects that you walk us thru.

      @Pntz Englnd Well... Where do I begin...? 😂
      I built it from plans I found on the interwebs, but when it came to welding the springmountjointthingmabobber I turned it the wrong way so the springs doesn't pull enough. So now it has like 4"/100mm of stroke, should have something like 20" 😂🤦🏻‍♂️
      Haven't really done any blacksmithing since I finished it, started working on my cars instead.
      And yes, Jönsson svensk 😉

    Hoe ram bits don't have as much carbon as you would expect because they are subjected to so much stress and you don't want them to break. They also have a small amount of molybdenum and Manganese (usually around 2% of each) sometimes tungsten as well depending on the manufacturer. They are excellent steel for what they are made for. I have used this metal in making gun parts a few times and it works great because it doesn't wear much over time. I normally ice quench the contact surfaces and let the part air cool. One thing you will find is that it doesn't forge weld very well. As you probably have much more blacksmithing experience than I do, you probably know more about why that is than I do. Hope this is some help to you. Oh yeah, before I forget, I really enjoy your videos.

    Just a FYI the flatter I made 20 years ago was never hardened and it is still fine. Sure harden it if you wish but as a struck tool on hot metal, dead soft is fine. Also, it will get hot when in contact with your work and will aneal more anyway.

    And this is why I use S7 for all of my tools. No guesswork and S7 is incredibly forgiving and more than tough enough for hot work even if with less than perfect heat treating. If I ever get an electric oven, I may start using H13 but until then I'll take the convenience of S7.

      possibly, but since it couldn't be broken after the oil quench I doubt it had any cracks. If it were cracked after the water quench it probably would have broken first hit. But that is why I discard all of the steel involved in that test.

    Could just heat it to the non-magnetic range to determine the critical range? Or is that not a universal.

      I’m afraid it’s not accurate. Most steels loose magnetism in the 1450 range but some have critical temperatures much higher. That work for simple steels like 1085 or W1. But not so well if it is something fancy.

    The twist is super annoying. Happens to me all the time making flatters and bottom tools. My tools always have a left-handed twist; maybe because I'm left handed? To correct it, I forge the high corners down, turning 90 degrees every blow in between upsets at the block.

      Several people have been sure they knew exactly what it was. Sadly no two seem to agree. It did get quit hard at 1500, not sure if it needs the 1650. 450 did result in a better tempering

    • @Fireworxs2012
      @Fireworxs2012 5 років тому

      Hey there Mr. Bear...You are correct. Without further testing (spectrum analysis) it's impossible to know what it is for sure..That said, 25 years ago I had a Buddy that worked for the Nebraska State Highway Commission. Occasionally they would break a road breaker bit and he would grab it. Those Bits were 8630. From the video & what you describe from your spark testing and seeing how it looks when you're working it (it has a slick almost wet look to it when cherry red) it sure looks & acts like those old Jack Hammer bits. 8630 is basically 1060 with extra chromium, nickel & molybdenum..Makes lousy knives, great forming tools. (swages, fullers, & wutnots)..Dial down the tempering and it makes great wear plates.. Less finicky to forge than Shock series steel, super tuff stuff when tempered right...Always thought it would make great anvil plates..Anyway, that's my 2 cents worth..*tosses a nickel on the table..Can't help wonder how many feet of snow you guys got down there...

      The problem with learning on scrap is that it all behaves differently and you never know if you are having problems because of your technique or because you found some odd bit of steel. Learning on mild steel keeps that one thing constant and once you have developed your technique it is easy to tell if a particular steel has its own problems, which many do.

    people often seem to overrate the heat treat of steel, this might be due to the constant circle jerk happening around it. in the end, it doesnt really matter here anyways, the hammer needs to be hard enough so it doesnt get deformed by the thing you are hammering on, but thats already it. if you'd care about the hardness of the end result, you shouldnt make it out of an unknown material in the first place, so not having the tools to determine what material it most likely is, isnt a drawback here
