How could i make something like this? The whole thing is solid hardened steel. It retails for around $240 but i feel like it could be made diy for cheaper

    What is it for? Does it need to be hardened steel? It would be very hard to do without expensive equipment because of the material

      This. What is it for? Does it need to be 100% solid? and does it have to be hardened steel?

        It's a tool to break thin stones in a predictable way. You place a stone on top of it, hit It from the top and it breaks over the tip. as I said it retails for around $240 which just seems ridiculous but then again I'm not a steel guy so maybe that price is right.

        I was thinking of trying to get a piece of thick angle iron, like 1/4", sharpening the corner, welding it to a base plate and trying that out. Although I think it's meant to be made out of solid steel as it apparently weighs 12lbs, so I'm unsure if a piece of angle iron would work because it wouldn't be heavy enough.

          As the other anon said
          https://www.harborfreight.com/5-lb-wood-wedge-94349.html

          If it needs to be a wider angle, just slap two of them together and then grind the points together

          Part of the hardness requirement comes from that edge. It's hard to make an edge hold up to that kind of use without a really hard material.

          In order to fabricate something like that you’ll have to learn more about hardness from an engineering perspective. You don’t need a college course, but you’ll need to research what goes into surface treatment of steel, the hardness of the stone you wish to work with, and how to get a higher hardness on the exterior surface of a part like in OP to begin with.

          Youll also want to make up a free body diagram of this part to get an idea on the forces involved in the parts use. Even with a hard enough surface, the part will have to be strong enough to withstand what you’re doing to it.

          You could try to copy the real part’s geometry and do the rest through guess work and experimentation, a lot of times thats enough to get results.

          You will be hard pressed to match the quality of this expensive part with your own work. Understand that many professional manhours have already gone into designing this part and its manufacturing. It may not be worth the time you would have to spend to emulate that. That ultimately depends on you.

            A lump of steel isn't that hard to replicate.
            A hardened tool designed for a specific purpose, regardless of how "simple" it looks is extremely hard to replace. It's like asking if you can make your own surface plate at home. Yeah you "can" do that, but the amount of engineering required to make that possible is not worth the $240 you'd spend just buying the damn tool

          Ok what i would do is go to a place that parts out heavy equipment and get a piece of cutting edge as wide as you want your stone breaker to be. Weld that to a heavy base plate and add some gussets on each side to make the wedge shape. I would leave like an inch or two of cutting edge exposed at the top for future sharpening...

          Or see if they have any old cutting tooth points they would let you have for cheap. That might be all you would need...

            By a cutting edge do you mean something like this? Because this looks like it could actually work pretty well. Thanks man, great ideas.

            It looks like if i got a thick enough piece of steel i could just grind down the tip of it to make an edge like this and it would work too. The only tools i have at my disposal are grinders of various sizes

    How thick is that steel? If it’s like 1.5” or 2” and mild steel at first, all you need to do is make a few 30deg cuts, maybe you could do it slowly with a steel blade on a miter saw while spraying it to keep it cool, then tap the bottom of the two pieces with a couple holes each, bolt it through the plate. The steel is so thick that a few bolts on the bottom may hold the apex of the triangle together as long as your cuts are good without welding it or anything. Harden the pieces after you cut them?

    So you would need like 12” of that ~1.5”-2” thick bar, a steel cutting blade that may be dead at the end, and whatever 6”x6” plate for the bottom.

    Could you do it with mild steel then treat it? Might be a little easier, maybe.

      How do you treat mild steel?

        Carburize it.
        But the correct answer is to make everything out of angle or channel and then braze in a piece of hardened steel into a notch at the top that you left to accept your hardened piece of material. As for material, there are dozens of pieces of barstock that machinists use (HSS or any other grade of tool steel) Some tool steels will be too brittle, so you may need to anneal it just a bit.
        The other answer is a redesign. Since you’re just using it to break stones, you can take a long piece of [preferred/cheapest grade] hardened steel and bolt/screw/epoxy/wire tie/zip tie to a piece of plate steel and you will be in business. I can’t imagine why it would need to stand six inches tall. A quarter inch height should be enough to introduce the fracture into the stone.

      You're an idiot. Why did you post? Copper is more expensive than steel and a worse material for cutting tools you numb digger.

    if it isnt hardened it will just deform the first time you use it and be useless.
