I want to see so much more iron casting and work on improving your green sand! This was so cool. And working with Joseph and HTME was cool and would have enjoyed more with them
There really isn't enough cast iron stuff on RUclips, I'd love to see them do other stuff with it like recreating antique tools and gadgets or 3d model new ones and print them out and cast them.
1.) It's not hot enough, you need to get well above its melting point to ensure it flows into the mold properly 2.) the molds need to be vented in some way, the air inside them needs to go somewhere. The wet sand will hold its shape but it's not porous enough to allow natural venting 3.) the bubbling in the open molds is a result of the mold containing moisture. Even the smallest drop of moisture can result in a steam explosion that sprays molten metal all over and causes bubbles in the surface. Preheat your molds until dry whenever possible.
Totally agree, but want to add that the way to increase the temperature is by adding oxygen... NOT using compressed oxygen from a gas bottle, but blowing in air with a blower, (a pipe through the sidewall of the foundry to which you attach an old hair dryer, although you can use a manual bellows if you need an intense arm workout). Also has to have a port for the air to exit, preferably creating a vortex inside the foundry, swirling around the crucible. The color of the molten metal is the indicator of its temperature. Red hot is not hot enough, orange-getting warmer, yellow-almost there, almost white hot, get ready to pour. Don't know for sure, but I think having the mould angled slightly downward from the sprue may help. Biggest thing though is venting. Trapped air inside the mould will prevent adequate filling. Here is a good resource on making green sand foundry101.com/mixing-sand/
Also you should never use wet molds you will have it make steam which can either produce air pockets in the metal or worst case it explodes in not a good way :)
Not to mention that a pre-heated mold will just cool the metal slower. Thermal transfer is proportional to the 4th power of the temperature difference, so even a little heat added to it will help a lot.
I've only ever casted aluminum and I did it nearly 2 decades ago but when casting, I believe we had a breather hole on the opposite side of the pour hole so it could flow without any pressure buildup. This will let the metal flow better in the cast and also let you see on the other side when you have enough poured as it will start to rise out the other side.
There are some amazing mold coatings that are like a ceramic paint but they use extremely flammable solvents that burn off almost instantly and leave a mirror smooth surface finish right out of the mold. I've done a lot of aluminum casting and I've cast over 1000lbs of lead so I thought I knew alot about casting. Then I watched some professional foundry workers and realized that I only knew about 5% of what there is to know about casting.
This, more than anything! It's also a good idea to make a riser, a reservoir above the mold which gravity feeds your iron in. Most guys use a soup can and some steel tubing as a form. It really helps to shove the metal into the corners.
I have completely stopped watching tkor after they got rid of nate and calli. At first i was a little skeptical of those two when they took over but they did really well and the experiments were great. Now the experiments are kind of stupid and boring and it seems as the whole personality of the show is just for kids no fun in it for adults anymore.
Yes! I would absolutely love to see you expand further into perfecting the pan. I just love all your videos, great job as always... Also, how cute was it making those tiny meals, oddly satisfying and funny. Lol
I'd love to see more of this. So many people don't show failures, but failing is often the best teacher, imo. I'd love to see you figure out what parts are going wrong and how to address them.
It would be best if the sprue was on the bottom of the pan and was large enough to act as the riser also to control shrink, the handle should have a vent on the tip. It will relieve pressure and signal a complete pour.
I remember from brass casting, your pore hole should be at the end of the handle. You might also put a pore hole on the far side of the pan. Build the sand mold withe the pore channels so you don’t have cave in. Cut off the excess afterward. Our castings used more than 1 pore hole to complete the fittings.
Hey Nate, worked in a legit iron foundry for a number of years, I have some tips that could help. Try adding a wooden bead around the inside of each mould half, ideally a half round dowel, 20mm diameter would work, or failing that, a 10mm square baton, nailed to the inside of the wooden mould halfway up, this would give the green sand something to purchase onto. Also, we used resin set sand "air set moulding" it used a slow curing resin mixed in with the sand, set in about 20 minutes, after which, we would remove the "pattern" (the thing we are casting and then close the two sides up. we would only add the pouring hole and sprues on one side of the mould, and we would also add a smaller pouring hole, that would allow the iron to flow through and not create an air pocket, ideally this would be polar opposite to the hole you are pouring into - feel free to hit me up if you want to know more. loving all of your videos.
I wondered if you could mix something in with the sand to harden it, but would resin be able to handle those temperatures, and would it be food safe with regards to residue? Also have you ever used graphite for molds?
@@DFPercush so we used resin in a commercial iron foundry, 100s of employees. So I assume it was the correct stuff. And at those temperatures, I assume anything that could be considered non food safe, would be burnt off by the 2000 degree iron. We made all sorts, including iron pans.
@@topcat2757 That's interesting, thanks for responding. One more question though, does the resin make the mold reusable, or do you still have to break it each time?
I think you need to add vent holes at the extremities of the mold to allow the air to escape. It’s creating pressure especially with the high heat. So once the liquid metal backs up, that’s it. It’s not going to go much further than where it is.
keep going. Love how you are willing to show your mistakes and how you learning from them. Life is not easy. Sometimes you fail. We really need to remind people that failing is not a bad thing.
The sand needs to have some oil mixed in to make the sand pack and pack the sand in layers when getting the mold ready also you need a pour spot and a return hole
Nate: YOU HAVE TO PUT AN AIR PORT OPPOSITE THE ONE YOU POUR INTO... AIR AND GASES HAVE TO BE ABLE TO ESCAPE JUST LIKE TRYING TO POUR INTO A BOTTLE AND IT SPITS BACK UP AT YOU. AIR CAN'T COME OUT THROUGH THE METAL BLOCKING THE ENTRY. REMEMBER HOT AIR EXPANDS AS WELL.
One thing I especially love with your channel Nate, is that you are proud to present even the partially-succeeded, partially-failed projects like this half of a pan. The same goes with the brass blade you attempted to make. This gives more realistic touch to your videos as DIY projects aren't always completely successful, sunshine and rainbows. It is often demotivating if people try to repeat a DIY project they see online and don't get the same perfect results right away. It is always a learning process (which is good) and needs several attempts but at the same time this is often hidden behind the edited videos.
I think this amazing, and I feel that if you "perfect" the casting cast iron pans" then you'll work out all sorts of issues. One thing I think you need is an exit or vent hole. As you pour in the molten iron the moisure in the sand turns to steam and expands... that might also be hindering the pour. So a vent hole on the fast side of the mold might make a huge difference. You can make it with sometime as simple as a straw while the pan is still in the mold and a decent cardboard straw should be enough, can even leave it in the sand while you pour as it'll burn off if it gets too hot.
Yes, I want to see you do more with cast Iron! A blower will help get the temps up higher in the propane foundry/furnace. I’ve melted steel using dense fire bricks, a weed burner and a $20 Home Depot shop vac on blow. Your setup is much better insulated than anything I’ve used. Adding a flux, like quartz sand and borax will help with cleaning of the iron, lowering the melting temp and making the iron flow better.
I think you should continue on with it. The reason is that, if you figure that out, then there's other things you'll be able to make. It will widen your world of metal working.
Also, when you're cutting the excess of the pan, it would help if you heat up the whole thing with a blowtorch in order to prevent any massive temperature gradients where you're cutting, I've cracked a cast iron pan by having it on a Swedish One Log Fire and strong winds hitting the side. Same goes for if you're welding cast iron, but that's a whole different set of skills. Great video regardless, I'm glad to see you didn't give up the moment you saw it wasn't going perfectly. Well done, and thanks for bringing back the golden days of TKOR.
Absolutely would love to see more. The forge episodes are the reason I started watching TKOR. Was pretty cool to see you upscale the forge and would be cooler to see it improved
speaking from experience, Nate you need to add 3 to 4 channels into your mold to allow for the air pocket to be moved into. It is that air pocket that is stopping the molten metal from spreading farther into your mold. You can also try adding an overflow channel at the other end of the mold to allow the air to escape and so you can see when you have added enough molten material in your pore.
Idea: maybe use a thicker mold that way the iron can seep into the mold better. as for the green sand I think you need more clay in your mixture. great video!!
Yes! I'd love to see you try and get a full pan! > Like many here I'm curious why you didn't attempt to have the pour hole deposit molten iron into the middle of the pan so that there is a better likelihood that it would reach the edges before it cooled off. > Also, perhaps instead of making a pan, make a griddle instead?... it's essentially just a flat slab of cooking surface and you can use a small baking sheet as your template... you can even carve some strips (or press small rebar?) into the top mold to create raised metal rows that can create grill marks... the back side can serve as your flat top. ;) Looking forward to what you come up next!
I am so personally invested in ensuring this gets hundreds of thousands if not millions more views I need to see you continue to pursue this please i need a full pan
It’s just entertaining watching you figure things out, I wouldn’t know where to start with a lot of projects, and it’s nice learning an experience with someone else
With cast iron being flat bottom, one might be able to make an open topped mold so that you don't have to worry about flling a solid void that has no way for air to escape. May end up with a THICK handle, but you would be able to fully form the pan itself
Sodium silicate. Find out it's uses. Great for the kaowool and making green sand. I have made many kilns with kaowool and sodium silicate and fired them over 2200 degrees. Mix fine grain sand with sodium silicate to make green sand. I really like your channel.
It was so entertaining and awesome that you kept trying to make the best of what happened, instead of just ending the video. That is one reason why you are good at making videos.
Nate, I would love to see you continue casting iron! You might try increasing the oxygen to your burner with some external source like a blower motor or something similar or just add pure oxygen to the Vortex of the fire but don’t forget to use a flashback arrestor good luck!
We make brake rotors, tractor weights, pump housings, lifting weights, and fry pans all out of grey iron. Grey iron has graphite flakes which gives it that texture.
Hey Nate, while the pan is in the sand mold set your pour hole in the center of the bottom of the pan. Also preheat your mold so the pour temp doesn't drop so quickly.
Hi Nate got some ideas (humble suggestions) for your next skillet. When something round is laying flat, placing the pour hole (sprue) in the middle of the pan with thin air escapes around the edge and or at the end of the handle makes more sense (to me at least). when your stuck with course sand some funnel shape cylinders (with little handles on the top) that sit on the frying pan so as to tightly pack sand around them, removing them just before pouring to help avoid collapsing that can result from digging movement. After you refined the green sand mix just for fun, try doing it with materials of differing viscosity that cost less or don't need to melt (resin, wax, chocolate, sugar glass...).
It's so nice to be able to visibly see how much happier you are as of recent compared to when you first left TKOR. Its obvious the freedom of content and ability to be RANDOM is good for you
Not an expert by any means, but I did some casting in college. We had a pour channel and a vent channel on the other side so the metal would flow all the way through. Also, we used styrofoam as the mold so the metal would take the foam away and leave the casting. Also, I believe the sand had some oil in it. Hope this helps.
You have totally nailed what youtube is all about. Too many videos show perfection, and you do have perfect videos based on your skills, but it's nice to see you go beyond your expertise, and then we can watch your knowledge and skill set grow. Keep trying. I want to see all the mistakes and then the final perfect pan! Very funny content as well with the tiny meals and the effort you put into that as well, totally Nate haha
If you redo the furnace lid for future casting, drill some holes around the circumference and put some bolts through before pouring the cement. They will act like rebar and permanently attach the steel part to the insulation.
You might try a flux(say borax for instance) since that's a traditional way to lower the melting temperature required and clean the metals involved in casting. Add some plaster to your greensand and bake out your molds or make a full plaster lost wax mould. You should also have more fullers earth than that for iron as it needs far more mould integrity.
I would absolutely love to see you make a full pan from casting. It'll be very educational and friendly enough information to make me want to try it. Borox is used to lower melting points maybe that'll help you
I have a recommendation to help with your casting. Shape your desired piece out of paraffin or candle wax. Place this form in your Green sand and add pour funnel and vents. Pour your molten metal. The metal will burn away the wax, creating a draw, pulling your metal into the mold. Be careful because it will spit a little.
I would definitely love to see you continue your quest into casting iron. My suggestion is that the forge is too big for your burner. Adding a second burner should solve your problem of getting up to temperature. You also may want to add a vent hole in the lid.
I would love to see more of this. If you try again I know that it isn't exactly correct but you could put the spout on the bottom and have the air outlet on the handle. This would make it so the main part of the pan is the first to get filled and would push towards the outlet. You had to cut of the excess anyway and clean it up so it shouldn't be too different.
I've watched casting videos before and I've noticed that they add vent tubes to the mold on the opposite side from the pour spout for air to escape so that the metal can fill the whole mold. If you're going to try it again, you'd probably need to do that to get a full cast. Another person posted the same suggestion in the comments and called it a breather hole.
I wont claim to be the first. However I have used screwdrivers for cooking after a housefire left me living in a car for a couple months. I had decided to use only what I had with me so I could put my money towards rebuilding. What I had with me was the car which contained a camping stove a single pan a single pot and my tools. I did have a camping set of utensils but I was to lazy to bring those out other than my chopsticks which I only used when making ramen. A favorite dish of mine.
(1) Please make a Discord server! (2) Idea: You could use the lost-wax or lost-styrofoam method, but with the flat surface on the top. That way, the metal only has to go in the channels deep enough to make the sides and the handle, and you might get an uneven bottom (as in the part which sits on the fire, not the part on which you cook). Alternatively, you might want to use a plaster to make the sand tougher, to prevent the sand on the top side from falling on the bottom side. I think you should also try to use a geopolymer (cement-like) mixture of clay, lye, and waterglass or silica sand (there's apparently other sands, like granite sand, for example). The clay (ideally metakaolin, but any clay good enough for pottery works, and you can even use normal mud from the ground around the furnace), lye (sodium hydroxide, or potassium hydroxide which can be made by mixing wood ash with water and then the lye is dissolved in the water), and silica sand or beach sand (which can be mixed with lye (of any of those 2 types) to make waterglass) or waterglass, then the mixture will set like cement, and end up more thermally resistant than cement, closer to terracotta (depending on the terracotta and the geopolymer mixture). With a proper mold, especially if you can heat it a bit in the kiln, I think your chances of success are much higher. If you use cement, remember that you can use something like 3%-6% and 2-4 times more water than cement, and the rest can be the sand mixture you're already using, and after the cement cures (ideally using a cement which sets in 30 minutes or so, but one which sets in a day or two also works well), you can remove the positive from the mold (if it's not done using the lost-wax or lost-styrofoam method), re-assemble the two sides, and pour the metal. Depending on the mixture, you can also heat it slowly in the kiln or in a home oven, to get it hotter, so the metal flows a longer distance before it solidifies.
Not sure if I've said this before on here, but in my mind, Nate *is* the King of Random. You can change the name of his content, you can add new people to that other channel, but Nate will forever be the one and only TKOR.
Hey,Nate you made a very nice and surrealistic pan and I like it! Please do not throw it away or remelt it as it has merit as an object of art-way cool,man!
have u tried mixing a little bit of cement/plaster cause if I remember correctly from a "how it's made" episode large scale factories add a binder to prevent the sand from collapsing, also if the mold is too cold and causes iron to cool down too fast then simply preheat the mold as well. It would also be nice to see u cast pans out of other metals like aluminum or copper and why nobody uses casted aluminum pans or casted copper pans.
Ok I need to see this pan com out again the next time you have Calie help with "Brand vs Basic". And even if your casting is having trouble you seem to have gotten really good at just whipping together a foundry.
its strange, you see people in India building forge from scraps and melt iron and cast things perfectly in sand with used oil mixed in, but it seems hard for almost everyone in the west even with thousands of bucks wasted on gear... great video, keep up the great work...
Completely understand the set up, what we're the remaining parts list to complete making your furnace? Also, you should have made a 3 inch hole in the middle of the lid, pressure and such, as well as attaching the lid, so it will need to be lighter
I have an old huge cast iron pan, and there's remains of a pour spout straight in the middle of the surface of the pan. For some reason it wasn't properly ground down, and for some equally strange reason I never got around to grind it flat even though I've sworn about it numerous times as the spatula catches on it when scraping the pan. So adding a spout in the middle of the pan probably is a good idea as well as several ways for the air to evacuate the mold as you pour the iron. Another thing to consider is preheating the mold. It takes making a large oven and I have no idea how to stabilize the sand. But it's an idea. Perhaps try lost wax? Just throwing things out there...
Yes, try again. Next time, leave a vent hole opposite the pour hole, so air has a way to escape out the other side of the pan, as metal flows in. Also, cast the pan right-side-up rather than upside-down.
Since you've broken away from TKOR, it's good to see an unrestricted flow of ideas! Maybe it's some sort of confirmation bias, but after watching your "Why I Left" video, looking back at the more recent TKOR vids, it's obvious they were chasing the algorithm. It's refreshing to see quality ideas put to the test in your content. Keep it up, man!
You should add a vent. So the air can escape. Add another burner to the furnace. One doesn't look like it's doing the job. Add a hinge to you furnace that will allow you to slide it out and back in
I knew as soon as Nate made his own channel he'd do videos like this and i hope he can grow and get millions of subscribers i hope his channel goes far and it's successful.
super fine sand mixed with sodium silicate, make your mold then bag the mold and flood it with CO2 to set the silicate. Also use a sprue on the opposite end of the fill to allow the gases to escape out instead of getting stuck inside the mold.
Would love to see a a custom cast iron skillet made, not that there is a lot of room for customizing but maybe one you designed yourself! Love the video

I appreciate your dedication to "cooking tiny food on this tiny pan", Nate. 😍🥰👍
YES!
Can't help but think you should use the handle as a pour spout and cast it vertically to reduce heat loss.
This honestly drove me a little insane 😂

It would be best if the sprue was on the bottom of the pan and was large enough to act as the riser also to control shrink, the handle should have a vent on the tip. It will relieve pressure and signal a complete pour.

You can also try adding an overflow channel at the other end of the mold to allow the air to escape and so you can see when you have added enough molten material in your pore.
Idea: maybe use a thicker mold that way the iron can seep into the mold better. as for the green sand I think you need more clay in your mixture. great video!!
It's a proof of concept, a Fine art piece, and a nouveau gourmet experience. Great show Nate.
I think if you had done it with two different pour spouts. One on each end, it would of poured and filled the cavity better.
would have***
Yes! I'd love to see you try and get a full pan!
> Like many here I'm curious why you didn't attempt to have the pour hole deposit molten iron into the middle of the pan so that there is a better likelihood that it would reach the edges before it cooled off.
> Also, perhaps instead of making a pan, make a griddle instead?... it's essentially just a flat slab of cooking surface and you can use a small baking sheet as your template... you can even carve some strips (or press small rebar?) into the top mold to create raised metal rows that can create grill marks... the back side can serve as your flat top. ;)
Looking forward to what you come up next!
I am so personally invested in ensuring this gets hundreds of thousands if not millions more views I need to see you continue to pursue this please i need a full pan
It’s just entertaining watching you figure things out, I wouldn’t know where to start with a lot of projects, and it’s nice learning an experience with someone else
With cast iron being flat bottom, one might be able to make an open topped mold so that you don't have to worry about flling a solid void that has no way for air to escape. May end up with a THICK handle, but you would be able to fully form the pan itself
Nice idea
The 2nd attempt in the sand mold looked awesome! It would be cool on a desk, side table, or dresser as a small items holder!
Sodium silicate. Find out it's uses. Great for the kaowool and making green sand. I have made many kilns with kaowool and sodium silicate and fired them over 2200 degrees. Mix fine grain sand with sodium silicate to make green sand.
I really like your channel.
It was so entertaining and awesome that you kept trying to make the best of what happened, instead of just ending the video. That is one reason why you are good at making videos.
We need a
"FIT FOR A SMALL KING"
T-shirt with picture of that pan 😄
Nate, I would love to see you continue casting iron! You might try increasing the oxygen to your burner with some external source like a blower motor or something similar or just add pure oxygen to the Vortex of the fire but don’t forget to use a flashback arrestor good luck!
We make brake rotors, tractor weights, pump housings, lifting weights, and fry pans all out of grey iron. Grey iron has graphite flakes which gives it that texture.
Absolutely would love to see a part 2 to this project! Good first attempt though!
(Also let us know your solution for the lid issue on the foundry!)
We need to see a complete pan. Loved this, keep it up.
I am happy to see you continuing the videos. I cast aluminum and have wanted to try cast iron. This is great encouragement.
Thank you nate, its so important to see the failures. I know everyone who posts pours and castings, doesnt show failure too much
I absolutely love how it went from Nate from the Internet to Nate from the tiny cooking channel lol good job dude
Hey Nate, while the pan is in the sand mold set your pour hole in the center of the bottom of the pan. Also preheat your mold so the pour temp doesn't drop so quickly.
I'd definitely love to see you pursue casting like this further! This was really cool, and almost worked. Good job!
Hi Nate
got some ideas (humble suggestions) for your next skillet.
When something round is laying flat, placing the pour hole (sprue) in the middle of the pan with thin air escapes around the edge and or at the end of the handle makes more sense (to me at least).
when your stuck with course sand some funnel shape cylinders (with little handles on the top) that sit on the frying pan so as to tightly pack sand around them, removing them just before pouring to help avoid collapsing that can result from digging movement.
After you refined the green sand mix just for fun, try doing it with materials of differing viscosity that cost less or don't need to melt (resin, wax, chocolate, sugar glass...).
yes you absolutely do need to give this another try
It's so nice to be able to visibly see how much happier you are as of recent compared to when you first left TKOR. Its obvious the freedom of content and ability to be RANDOM is good for you
Not an expert by any means, but I did some casting in college. We had a pour channel and a vent channel on the other side so the metal would flow all the way through. Also, we used styrofoam as the mold so the metal would take the foam away and leave the casting. Also, I believe the sand had some oil in it. Hope this helps.
Heck yeah! I love cast iron. Be cool to see you make a full pan and cook some more things!
You have totally nailed what youtube is all about. Too many videos show perfection, and you do have perfect videos based on your skills, but it's nice to see you go beyond your expertise, and then we can watch your knowledge and skill set grow. Keep trying. I want to see all the mistakes and then the final perfect pan! Very funny content as well with the tiny meals and the effort you put into that as well, totally Nate haha
If you redo the furnace lid for future casting, drill some holes around the circumference and put some bolts through before pouring the cement. They will act like rebar and permanently attach the steel part to the insulation.
You might try a flux(say borax for instance) since that's a traditional way to lower the melting temperature required and clean the metals involved in casting. Add some plaster to your greensand and bake out your molds or make a full plaster lost wax mould. You should also have more fullers earth than that for iron as it needs far more mould integrity.
I can't wait to see what you'll be able to make once you figure out the green sand
I would absolutely love to see you make a full pan from casting. It'll be very educational and friendly enough information to make me want to try it. Borox is used to lower melting points maybe that'll help you
I have a recommendation to help with your casting. Shape your desired piece out of paraffin or candle wax. Place this form in your Green sand and add pour funnel and vents. Pour your molten metal. The metal will burn away the wax, creating a draw, pulling your metal into the mold. Be careful because it will spit a little.
I would love to see a full pan. I want to see more. 🍳
I would definitely love to see you continue your quest into casting iron. My suggestion is that the forge is too big for your burner. Adding a second burner should solve your problem of getting up to temperature. You also may want to add a vent hole in the lid.
in bigger iron melting processes, the heat is put directly into the iron instead of around it, often with an arc furnace
I think the larger pan will be easier to cast, and having a vent opposite of the pour spout could help the mold fill more complete/faster.
I would love to see more of this. If you try again I know that it isn't exactly correct but you could put the spout on the bottom and have the air outlet on the handle. This would make it so the main part of the pan is the first to get filled and would push towards the outlet. You had to cut of the excess anyway and clean it up so it shouldn't be too different.
The world's tiniest strips of bacon! And with a screwdriver spatula!!!
Just cool project, I'd be proud of that result for a first time.
Yes, i think you should totally do more!
You and HTME will be really great!
Introduce oxygen to increase temperature. Great video! I love how you still finish your project even if it's not complete.
I've watched casting videos before and I've noticed that they add vent tubes to the mold on the opposite side from the pour spout for air to escape so that the metal can fill the whole mold. If you're going to try it again, you'd probably need to do that to get a full cast. Another person posted the same suggestion in the comments and called it a breather hole.
What an adorable cast iron scooptula.
So glad you created you are still doing youtube videos.
I wont claim to be the first. However I have used screwdrivers for cooking after a housefire left me living in a car for a couple months. I had decided to use only what I had with me so I could put my money towards rebuilding. What I had with me was the car which contained a camping stove a single pan a single pot and my tools. I did have a camping set of utensils but I was to lazy to bring those out other than my chopsticks which I only used when making ramen. A favorite dish of mine.
(1) Please make a Discord server! (2) Idea: You could use the lost-wax or lost-styrofoam method, but with the flat surface on the top. That way, the metal only has to go in the channels deep enough to make the sides and the handle, and you might get an uneven bottom (as in the part which sits on the fire, not the part on which you cook). Alternatively, you might want to use a plaster to make the sand tougher, to prevent the sand on the top side from falling on the bottom side. I think you should also try to use a geopolymer (cement-like) mixture of clay, lye, and waterglass or silica sand (there's apparently other sands, like granite sand, for example). The clay (ideally metakaolin, but any clay good enough for pottery works, and you can even use normal mud from the ground around the furnace), lye (sodium hydroxide, or potassium hydroxide which can be made by mixing wood ash with water and then the lye is dissolved in the water), and silica sand or beach sand (which can be mixed with lye (of any of those 2 types) to make waterglass) or waterglass, then the mixture will set like cement, and end up more thermally resistant than cement, closer to terracotta (depending on the terracotta and the geopolymer mixture). With a proper mold, especially if you can heat it a bit in the kiln, I think your chances of success are much higher. If you use cement, remember that you can use something like 3%-6% and 2-4 times more water than cement, and the rest can be the sand mixture you're already using, and after the cement cures (ideally using a cement which sets in 30 minutes or so, but one which sets in a day or two also works well), you can remove the positive from the mold (if it's not done using the lost-wax or lost-styrofoam method), re-assemble the two sides, and pour the metal. Depending on the mixture, you can also heat it slowly in the kiln or in a home oven, to get it hotter, so the metal flows a longer distance before it solidifies.
Not sure if I've said this before on here, but in my mind, Nate *is* the King of Random. You can change the name of his content, you can add new people to that other channel, but Nate will forever be the one and only TKOR.
Hey,Nate you made a very nice and surrealistic pan and I like it! Please do not throw it away or remelt it as it has merit as an object of art-way cool,man!
We need more of this. That was really cool to see
have u tried mixing a little bit of cement/plaster cause if I remember correctly from a "how it's made" episode large scale factories add a binder to prevent the sand from collapsing, also if the mold is too cold and causes iron to cool down too fast then simply preheat the mold as well. It would also be nice to see u cast pans out of other metals like aluminum or copper and why nobody uses casted aluminum pans or casted copper pans.
Ok I need to see this pan com out again the next time you have Calie help with "Brand vs Basic". And even if your casting is having trouble you seem to have gotten really good at just whipping together a foundry.
its strange, you see people in India building forge from scraps and melt iron and cast things perfectly in sand with used oil mixed in, but it seems hard for almost everyone in the west even with thousands of bucks wasted on gear... great video, keep up the great work...
As far as melting metals and making useful things out of scrap, YES! We all need the knowledge
I love it. I wanna see 3 things..
1: Can you open a bottle with your pan?
2: can you put metric conversions on screen?
3: Can you make more castings?
Completely understand the set up, what we're the remaining parts list to complete making your furnace?
Also, you should have made a 3 inch hole in the middle of the lid, pressure and such, as well as attaching the lid, so it will need to be lighter
I have an old huge cast iron pan, and there's remains of a pour spout straight in the middle of the surface of the pan. For some reason it wasn't properly ground down, and for some equally strange reason I never got around to grind it flat even though I've sworn about it numerous times as the spatula catches on it when scraping the pan. So adding a spout in the middle of the pan probably is a good idea as well as several ways for the air to evacuate the mold as you pour the iron.
Another thing to consider is preheating the mold. It takes making a large oven and I have no idea how to stabilize the sand. But it's an idea. Perhaps try lost wax? Just throwing things out there...
It'd be neat to see a full pan. Onward with the casting!
Nice! Getting to the fun experiments!
This gives me the original TKOR Grant Thompson vibes. Love this sort of organic, not “overly produced” vibe.
More of this...this is what made tkor so much fun to watch and learn from.
Yeah I want to see a full one I think it would be an awesome series.
Yes, try again. Next time, leave a vent hole opposite the pour hole, so air has a way to escape out the other side of the pan, as metal flows in. Also, cast the pan right-side-up rather than upside-down.
Yes!!! Size is fine. Would like to see a successful melt. And also the seasoning. :)
Since you've broken away from TKOR, it's good to see an unrestricted flow of ideas! Maybe it's some sort of confirmation bias, but after watching your "Why I Left" video, looking back at the more recent TKOR vids, it's obvious they were chasing the algorithm. It's refreshing to see quality ideas put to the test in your content. Keep it up, man!
I'd absolutely enjoy seeing you master this!
You should add a vent. So the air can escape. Add another burner to the furnace. One doesn't look like it's doing the job. Add a hinge to you furnace that will allow you to slide it out and back in
I knew as soon as Nate made his own channel he'd do videos like this and i hope he can grow and get millions of subscribers i hope his channel goes far and it's successful.
super fine sand mixed with sodium silicate, make your mold then bag the mold and flood it with CO2 to set the silicate. Also use a sprue on the opposite end of the fill to allow the gases to escape out instead of getting stuck inside the mold.
Would love to see a a custom cast iron skillet made, not that there is a lot of room for customizing but maybe one you designed yourself! Love the video
