    The key to avoid the folding is to make it in steps, increasing the depth of the mold each time. I think there is even theoretical formula to know how many steps you have to do.

Its so cool to think how many things deform in this way- clothing when you bend your knees and elbows, towles hanging on a rack, paper you crumple up, etc; all follow the pattern of buckling/folding. I guess this must be the cheapest way for the universe to deform flat surfaces or something? Its so cool

      @thomas robinette I am glad to hear that you are doing well money wise as that is always a good thing to not have to worry about. However, my point was to say even people that know everything there is to know about any give thing sometimes still have to work things out and don't just know the answer. D-day, who doesn't? June 6th 1944, the invasion of Normandy. No offence but what does the day you were born (other than the fact that you are probably retired by this point) or the amount of money you have, have to do with whether you have to work your way through a problem or not? Anyway I was not trying to be offensive in my previous post nor this one so I hope no hard feelings.

    Some thoughts I had mid way through the video: Would it be of any use to prototype molds with thinner gauge metal, or even aluminum foil? Perhaps adding some relief cuts in the blank would remedy the “bunching up” problem Maybe you could try forming metal preheated in an oven or use annealed stock

  • secretsquirrel

    Thanks for sharing this, I really enjoyed watching the iterations you went through. Thanks again much appreciated. What if something happened to fall and land at the back edge of the steel, could (or would) it fold down into your croc/foot? How heavy would something have to be for that to happen? I’m interested because I have a cautionary tale. I was in a shared art studio with several people working on different metal sculptures and related projects. Everyone was meant to be wearing steel capped boots (made to the Australian safety standards), but one dude had purchased a cheap pair. So anyway, he was cutting a big sheet of metal with a gas-axe, had the piece to be removed hanging over the edge of the workbench and….yeah, that large piece of metal (about an inch thick and approx 2foot x 1 foot) it fell down and landed right on the back edge of the steel toe, the steel toe insert bent down and cut into his foot, sliced off 2 toes and almost severed the others. It was a great day for everyone obviously 🙄. Long story short (er) Everything was (kinda) okay in the end, lots (and lots) of blood and lots of tools in the studio available for the paramedics to cut off the boot (Gag) And off to the hospital with toes in a bag that were then put inside another bag filled with ice. All toes except for one were saved. Soooo, LESSON LEARNT. Don’t be a cheapskate with safety gear…just don’t..NO. Also - Safety was drastically improved, footwear inspected prior to ANY studio access. No appropriate footwear, no access. Apologies for the overshare, but the mention of steel toes, always makes me think about that damn “back edge” and it’s guillotine potential - awesome I know. 🙂🐿

    • secretsquirrel

      @BlueFire Animations oh for sure, it was really obvious upon inspection (and he admitted to it) that he had purchased basically a fake pair of steel caps. Hence the cautionary tale. It’s frightening to think that people will manufacture fake safety equipment, but given the mark up, not totally surprising either.

    • BlueFire Animations

      I believe the back edge is reinforced on most steel toes to protect against this problem, I might be wrong though and it might just be my pair.

    Thanks for the video :) This is an interesting idea. I've head that steel toes may cause problems if a heavy enough object falls on them preventing the removal of the foot or even causing further damage. Even though this is just a prototype, an externally removable steel toe or "shield" may help mitigate this problem. Of course, maybe removing a steel toe or "shield" may not be the best medical course of action in all cases in order to stop bleeding until better medical help arrives. See the Mayo Clinic's website for better details.

      @Omega chad requiem Hey, don't write us off so easily! Blacksmiths routinely have to make shapes like that, and armorers existed well into the 1900's because they were making things like helmets and such. The tools and techniques haven't changed much in a thousand years, and what you see in the video is pretty much the same thing it takes to make a gas tank for a custom motorcycle or car fender. We're still here making cool things out of steel!

    • Three Rivers Forge
      Three Rivers Forge

      Exactly. I didn't want to brag or anything, but I was watching the video to see when he talked about annealing the blanks as they are already work-hardened from being made into the sheet that he bought. Never happened. He never used lube, either, and his blanks were a bit over-sized for what he was trying to accomplish. Of course, it's also a very complex shape he's trying to achieve in just one squish. Kudos to him for giving it a go!

  • OnTheRiver66

    I’m not sure of the condition of the sheet metal when you start, but I’m thinking annealing the steel first to soften the alloy to reduce spring back and allow the steel to more easily stretch during forming. If it is too soft for proper foot protection after forming it could be tempered to a spring temper if it has sufficient carbon content.

    I've made (heavy) fiberglass dies to do steel and aluminum pressings. I've pressed pieces up to two square feet. I have a large-platen 100 ton press. It's mostly a matter of location and keeping the material in place with pins. One thing that makes the pressing easier is to use low strength "tryout" steel. Only about 30kpsi yield, so it forms easily.

  • Matthias Wandel
    Matthias Wandel

    I'm surprised no one in the comments has mentioned "draw beads". Draw beads are bumps overwhich the metal is pulled on the edge of the form to put resistance to pulling it in. Not stop it from pulling it in, just resistance, so that the metal is under a lot of tension, which helps it stretch better without wrinkling. Go look it up. As a student, I once worked in a research lab that investigated the effect of different lubricants on draw bead friction. The auto industry spends a lot of money on this.

      @The Artisan Hack It's definitely a learning process. You have to account for the metal shape before being drawn. Variable resistance needed at each point... draw beads... wax... Etc.. I was just a temp monkey for a week or two that placed the metal and wax paper if needed then pressed a button. 🐵

    • The Artisan Hack
      The Artisan Hack

      @Tony Parker we do deep drawing also. Mostly aluminum. We run our blanks thru a waxer that coats the outer side with a thin layer that does the same thing. I think they tried wax paper at one time but it evidently didn't work for us.

    • Tony Parker

      I worked at a job making small sinks. They used wax paper under the metal as lubrication to make it draw easy and not bunch/pinch.

    I think it's too much of a bend happening too slowly. You should try making the cover in two steps. Instead of pressing the metal into the shape all at once, make the first tool not as deep. Then put the partly stretched steel into the final form.

  • empireDirt

    I would try forming the steel incrementally; in order to prevent the wrinkling; but that would involve pressing the steel with multiple forms until it gradually reaches the ideal shape.

    Nice work. Lesson to be learned from WWI. German helmets stopped bullets. Ours did not. Multiple pressings. Each going a little deeper, each time. Plus soapy water. This led to a more even wall thickness. So bullets to the forehead, temples, etc .... were stopped. Maybe that would fix your issue w/ folding/bunching up. I look forward to seeing more of your work!

    • ErikThorvald

      German helmets were not designed to stop bullets but lower velocity shrapnel and debris. the multi stage drawing process allowed them to to have a helmet that had more coverage of the head compared to the Adrian and Broady helmets. The Germans did develop special 6mm thick hardened steel brow plate that attached to the front of the helmet with 2 studs. these were issued to mg crews but were absurdly heavy and strained the neck. Because the Germans over engineered their helmets it took them much longer to equip their troops with helmets compared to the Allies.

    • Ewan F.

      @Chaste Thompson that's a good point. you could also rough out the piece with the press and finish it with a hammer. this would also give the benefit of work-hardening the piece, making it slightly harder, and less likely to compress.

    • Chaste Thompson
      Chaste Thompson

      They might could also try planning for the wrinkles instead of trying to remove them entirely. Because there's that portion they cut off, if they can figure out a way to get a repeatable, uniform fold there, it would keep everywhere else from wrinkling. As long as the actual part turns out okay, it doesn't really matter what shape the excess material is in. You could probably accomplish the same thing if you made a cut there, but that would be an entirely separate new step, so it seems like too much effort here.

    • Ewan F.
      Ewan F.

      using multiple passes to form the piece will help a lot. my 2 cents would be that one could use a half-sphere with a corresponding negative to form the piece, moving the piece of metal so that the press acts as essentially a replacement to hammering by hand. one could also use just the negative half of the form and use a hammer to shape the metal. this would allow you to hammer out wrinkles as they appear, resulting in a less complicated overall method of construction, however this would remove the benefit of automation. one could also rough-form it with a press and finish it by hand, thereby resulting in a better fit as well as less complicated press tooling. i don't have much expertise in press-forming, so i could definitely be wrong, but i don't see any reason it wouldn't work

    Die design is a fickle beast. Easily as much art and intuition as science. I must commend you. You have wrapped your head around draw die concepts that take years for some die design engineers to grasp. And you’ve done it with a Chinese press and some scraps of wood!! As far as showing your face on camera...I’d say whatever makes you more comfortable and doesn’t interrupt you workflow too bad.

  • corey miller

    I use to work for a company running a press machine to make car parts and of course it was all metal on metal but it would stamp down multiple times slowly forming the shape more and more each time it goes before it got to the end, to avoid it crinkling and such

  • Gaming History Source
    Gaming History Source

    I used to work in an automotive press shop. We made parts for BMW. From my experience I can tell you that pressing the part in one go is not the best method. The way the presses worked in the automotive field is that they used a step method. The part was stamped out bit by bit using large rolls of sheet metal. The stamp would come down on one part of the metal & make a shape into it. Then the moulds would open up on top & bottom & the sheet metal would me moved along to the next stamp. So on & so forth until the final part was clipped off at the end of the run. This would prevent the metal from buckling & would provide a nice consistent form The extra scraps of metal would fall off into a conveyor system where it would be routed to a metal collection bin that would then be remelted & reformed into new sheets of metal. Nothing went to waste.

    You are so right about this part 15:32. In designing stuff you have to ambrace failure. I know it can be hard for some but I would say to become a good designer in general one must to learn to fail fast to get to the end goal. We shouldn’t spend too much time trying to think if the prototypes along the way are finished or not becouse we just want the end product to work. Embracing failure is one of the ten design heuristics I live by and apply it to my own business

    I come from aircraft engineering so I’m more of an aluminum guy, but we would typically use annealed stock for a formed part with radii that tight, and then use the work hardening itself or tempering to hit specs. I’d reason that you would still run into some issues if you fully annealed the stock at the start just based off the gauge you’re going with, but if you started with an initial rig that is similar to what you have going, I’d say you could take it three quarters the way to your ideal shape and avoid buckling. From there you could trim to your final dimensions, hit it with a quick torch anneal (benefits of it seeing a croc and not an aircraft haha), and then pop it into a final forming block (a registration pattern of some sort would be helpful) that would set your final dimensions and work harden it back to steel toe territory. Would hopefully avoid a lot of springback related calculations, and would mostly just give you an excuse to put a mirror polish on those bad boys! Anyways, just figured I’d throw my hat into the ring! Who doesn’t love a little armchair manufacturing engineering? 😂 Love the videos!

      I was thinking about that too but then my brain said "you can't harden mild steal so annealing it wouldn't matter" but then it occurred to me that I don't know what I'm talking about so I thought all that was definitely important to tell here because..... reasons

      @Sac Winged Bat's a Tad Bit Sad having done a bit of work with mild steel sheet to make an instrument, annealing really helped me get the tight curved I needed without any buckling or cracking

      Steel doesn't typically work-harden, you have to heat it very hot, above the Curie temperature, and cool it quickly to achieve any real hardening. Even that's only true for high carbon steel, which I doubt the sheets in the video are. What they most likely are is mild steel which hardly hardens at all so I doubt annealing would do much to help. Doing it in multiple steps to prevent springback, or hammering it which essentially just bends the metal in hundreds of steps, each only moving the material a little would certainly help regardless, but steel is just a lot tougher and harder material than aluminium and your only two real options are a stronger mold and brute force or a metal mold and hot-working the steel.

      @Stock photos guy when you bend or harden metal, you leave a lot of stored stress in the metal. Stored stress makes metal hard, which also makes it difficult to bend. Making the metal really hot, keeping it hot for a while, and then letting it cool really slowly gets rid of the stored stress. With less stress, the metal is easier to bend. The process of heating, holding, and slow cooling metal to remove the stored stresses is called annealing. There's actually more to it involving the crystal structure of the metal, but that's the easiest explanation for layman's terms.

    This was a technique from back in medieval times for shaping steel sheets into armor, they would burn out and carve shapes in stumps and get to work with a hammer. I got the chance to bang out some plate armor and it is a very labor-intensive process of going back and forth especially if its armor that is being fitted for someone.

    I've been talking about steel toed crocs for years as a joke but seeing it become a reality is kind of surreal

    • lusteraliaszero

      it's been a thing for years in scandinavia, not crocs as in the brand, but security clogs/sikkerhedstræsko.

    I'm still confused if wouldn't be easier to pre-cut off some of the steel, for then when pressing the metal, not getting those distorted sides.

    I thought this video was going to be boring. Spoiler alert: it wasn't! Great video, would love to see timestamps on future videos to relate to your working hours!😂

    when he realizes he has to make another tool for the left foot

    • soundgod06

      Really he could probably do it quite well with one tool that has both left and right in a sort of kidney shape. He already added that extra lump on the back to balance the form, might as well make that off cut lump useful.

    • LexMc0606

      Shhhhhh... Don't tell him yet, he can figure it out on his own. His IQ is bigger than Mount Everest, he'll figure it out.

    I've only formed with sheet metal a few times once with forming blocks and aluminum sheet metals to make convex shapes with two different sets of sheet metal hammers and a second time to make a form of the joggled piece of metal to conform to the shape of the aircraft spar part that I created I formed using the piece of sheet metal and the metal form and the hydraulic press that allowed me to get to that form of shape I formed the metal parts without having to use a bunch of technical equipment like you did and still gave me smooth and accurate forms of the parts however I do like the way that you did it and if I had the technical equipment like you do id gladly do it the way you did it

    I like how you talk about mass production, yet you have only developed the tooling for a single size croc, let alone a single side of a pair. It would be interesting to tackle this with progressive forms that prolong the forming process by decreasing the applied force at any one time; the theory behind lifting objects with ramps in affect.

    My first solution would be to try and make it a 2 step pressing. First the outer edge and then the inner top

  • dmarkieb

    Maybe pre heat the steel before you start the pull process? When i am bending aluminum I heat it a bit to keep things from cracking.

    I am new to your channel and was wandering what your formal educational background consists of? Software engineering with Applied Mathematics and or Mechanical Engineering maybe? Coming from and undergraduate background in Math & Physics and retiring from Software Engineering 6 years ago, I find your projects interesting in both the technical and creative side. Good stuff young man! Keep it coming. Most enjoyable.

    Actually, Dutch style wooden clogs are quite comfortable and protective. Farmers and country workers in Holland France and Germany still wear them.

    i think cutting some extras in the beginning esp from the corners will reduce the chance and intensity of crinkles and creases. there should be less resistance (ideally, so that you don't have to cut at all any extras at the end!) idea: how they press soda cans.

    I dreamed about steel toe Crocs since I first started wearing them in the shop. I can't believe I'm not alone. Will definitely buy ones..

      They do make croc type shoes with protection. Toffeln EziProtekta comes to mind. Look around in your work shoe stores, you will find them.
