Your nickel strips were most likely nickel coated. It is very common for nickel strips to not actually be nickel if you get them from a an unknown vendor.
This is exactly what I was thinking, it's a big problem in making DIY battery packs for Esk8, you could probably check if it's coated using a magnet. P.S. love your stuff
My thoughts as well, nickel plated steel is usually sold as nickel strips. Scratch the surface and check if they rust in salt water. I've had good results with nickel strips from nkon.nl for battery builds.
I was also thinking his white vinegar might not have been concentrated enough and the excess water caused oxidization which if I remember right makes it brown
I know, three year old video as of my writing this, but here's an idea: 1. 3D print a mold that you can press ceramic clay into, less likely to crack than 3D printed ceramic. 2. I could see the silver paint after your copper electroplating. Probably needed more time coating, I'd also add a layer of nickel too, get it all much more solidly metal, which would add durability to your parts. 3. As for what another user suggested, coat all of the part, especially the inside, that will add greater structural support. 4. Alternatively, you could use a layer of fireplace adhesive (I forget the name, but I saw you use it) to coat the inside if you are concerned with heat resistance. I have been binging your content lately when not working on papers, it's been relaxing for me to watch you build cool stuff and cause explosions.
It's usefull to find coments suggesting improvements in his crazed designs, even in older ones. I'm binging his content too and I always scroll down through the first most upvoted comments to see what people suggest he does better.
Integza, after watchin this I'm gonna recommend some safety glasses. PLEASE! The engine exploded in your face three times at least in this video. Maybe even a face shield.
Please up vote this so he sees it, I’m always too late to comment so even though I’ve suggested it a few times I doubt he’s seen it. Just dip in weak sodium silicate solution and set with co2, rinse with water to remove the sodium carbonate, dry part and repeat a few times. It will fill the matrix with silicon dioxide until by definition it is non-porous. Then resister to combine into solid ceramic.
Funny.. i added a comment saying the same thing before I read this one.. it should also strengthen the parts since it is already used as a high temperature adhesive.
problem I see with this is you end up with either aerogel formation which has a much lower thermal survivability than people realize as it collapses, if you use the water and dry method you get silica gel which any water causes tiny fissures and liquid water outright causes it to split and explode like some ice cubes will when dropped in water, but for a very different reason. To get the effect he needs it needs to be held into a mold and fired to bring the SiO2 to full density, before being allowed to expand freely, for a higher temp than both of these, I would suggest sodium alumina as it will collapse if done correctly into a solid transparent aluminum ie sapphire glass, with considerably higher melting temps, so alumina aerogel will last in higher temps too if you want a good insulator to keep the heat in, tougher exterior to keep leakage from occurring and all that jaz, but honestly I would love to see him cat up all the parts and use spin friction welding with titanium wire on a dremel on sheets cut to shape and make it out of solid titanium, as he would be on course for making rockets he could launch into space and have the first tomato free satellite network ;) *there are a couple ways I have theorized to desalinate the sodium half of the silicate and alumina compounds with, with out an acid that actively pulls it free from the product leaving a pure substance against the surface, and then using laser tech to densify it, in layers, against the surface of an expanding conductive coated shape like say a round bottom flask grown around a flask shaped blown up balloon coated in graphite conductive paint to make it an electrode, that can be collapsed afterwards and withdrawn from the vessel, but it has not been tested yet.
@@ThomasAndersonbsf I don’t have time to debate you, but it’s obvious from so many claims there you have a lax understanding at best how any of that works.
@@ThomasAndersonbsf aerogel does use those elements but the method is incorrect for forming it. Try watching nile red's video on aerogel and you will get a better understanding on it.
Try adding fuel, igniting it, and then adding oxidizer, to prevent those explosions (hard start). You were right about the accumulations inside the engine and the spark plug, but I think that your mixing also is in play here. What happens when you add oxidizer first and then fuel is you get a stoichiometric mix of fuel and oxidizer in the chamber, which detonates just like any explosive.
Chemist here! try to buy nickel carbonate (NiCO3), should be easy enough. And THAN convert it to nickel acetate by just letting the NiCO3 react with AcOH. Did it once and it worked perfectly. Just take care about the bubbling of CO2, so stirring and slow addition is necessary. After that, just boil the water and acetic acid out. 120-130 °C should work. Use an oil bath if you can. Direct heat from a heat plate could cause problems :D good luck! EDIT: please be careful with the nickel ions since they are poisonous and wear safety goggles :D EDIT 2: Use 100 % AcOH, or at least 25 % (should be easier to obtain). Or, I could send my leftovers to you :D
mr. chemist sir.... this isnt necessarily a chem question but maybe you'd have some insight... he was talking about using graphite paint to make the ceramic surface conductive... could graphite be mixed into the slip and then sintered onto the surface? or is the fact that graphite itself is used for things like crucibles an indication that there is no way that makes sense?
or even, now that i think of it... instead of painting the ceramic... finding out what the solvent was for the silver paint, getting more and diluting it, and dipping the parts in the diluted paint to slowly build up an even coverage that covers parts that paint wont reach
13:20 omg I'm very happy you got those valves. Especially after the test earlier in the video where the fire went back into the tube. I was thinking... what happens when that fire goes all the way to the tank... Yea please don't die! Very happy you have those protection valves now!
Please wear PPE especially goggles your sister was wearing goggles. when printing parts an O-ring grove (RTJ ) and use a high temp o-ring. Mating flat surfaces together is hard - in pressure valves flat surfaces are machined and lapped to a mirror finish. if you are going to use flat surfaces and liquid gasket try using a spiral serrated / phonographic surface, or pick up a sheet of gasket material, its fairly inexpensively and easy to use.
Someone has probably already told you that copper plate is the foundation for a lot of metal plating including nickel. It looks like your copper was not covering the parts very completely though. Also the silver didn't look thick enough. I suggest more than one dip in the slip to build that up, then sinter it, then thick copper followed by thick nickel. Remember to polish the silver as much as possible, same for the copper to get better adhesion of subsequent layers. Also, of course you should look at what parts of the printed components physically blew open and make them a bit thicker. Anyway, I hope this is as much fun for you to do as it is for us to watch!
I know this is a year old, but putting an electric valve to cut off the gases in case of an emergency should be on your list of todos. Love your videos!
Hey Integza! I had an idea as to why your nickel strips caused that brown solution. Usually, those nickel strips are sold for homemade battery packs and it is unfortunately common for strips to be advertised as 99% nickel but are actually nickel-plated steel. hope this helps!
@@Nothing_._Here chloro-alki cell for making sodium hydroxide and hydrochloric acid, all part of that electrocatalytic process LOL (or just use plain salt no water and heat till it melts to make sodium metal using that process!)
Use a spring to return your rocket to its starting positon! Then you can put a ruler on the side of your rail and measure how far back the rocket gets using the camera. Use the spring equation and you'll be able to actually measure generated thrust!
You could of course just buy a force gauge (not really expensive) and then just hang the device on the rocket engine. maybe you still need a pulley system, but why simple when it can be complex.
@@albusdumbledore271 The word you're looking for is, "complex," not, "difficult." It would be quite easy to do what the op is suggesting. Tedious? Maybe. Difficult? Not really. Yes, this may seem impractical to you, but what makes you think that Integza is practical? The madlad literally stripped a linear slider off of his 3D printer because he couldn't wait a week for it to come in the mail! Lol In any case, using the spring would also allow Integza to introduce Hooke's law to his viewers, so that's a plus. P.s. I mean no disrespect by the way. I just feel like you were shutting down the op's idea without really considering what this idea would mean for Integza's content.
@@tremail564 You can also put the scale on the floor and have the engine thrusting upward. You'd have to measure the weight of the engine and subtract that from the scale's readings in order to get the thrust. P.s. Integza's done this before, I believe.
Something that could help you not burn a hole in your table could be adding something like a quarter turn valve. You start with it open, and if something happens, you can close it immediately instead of turning the tank valve for 15 minutes

My new hypothesis is that nothing is worse than wasps, no I WILL not be testing that theory, instead I'm stuffing it into this lockbox and chucking it into space.
Since you are using ceramics, it might be interesting to use one of the glazes that are converted to metallic coatings in the kiln. Normally you keep them away from oxygen by placing the hot ceramic in hay or grass so that the smoke displaces the oxygen.
The fact he has no safety glasses on while his face is a foot (about 30cm) from the rocket while everything is under high pressure is just..... AHHHHHH
He also hasn't put a quick valve on yet, so you notice to turn off the oxygen... The OXYGEN.... It takes him several seconds to turn the knob enough times. I wouldn't do this without a quarter turn valve on it

You should try casting the parts in metal using lost PLA casting using parts printed from your 3D printers. It's a new skill you can learn and explore that would make an interesting series to watch you learn the process.

@@ELYESSS He would be 3d printing... the casting! :) But yeah, I get it. Though I wonder what the physics 1st principles say about chamber pressure vs high-temperature material integrity of anything coming out from a 3d printer nozzle. Even with coatings. I'd love to be proven wrong though!
I am no longer allowed to repeat your projects in my home. As a 15 year old boy I guess I’m not supposed to make rocket engines in my bedroom Edit: r/wooosh to those of you who thought I was serious. And to those of you who recommend the garage, it’s a good idea but I don’t have one. I am actually working on a turbojet engine however and it’s gonna be like three feet long and the rest of the dimensions scaled to fit in our backyard. Our home was destroyed by a tornado like 8 months ago so now our back yard has like nothing in it so I’m gonna test there. And yes I am 15.
I dont know much about these things but I’ve been watching for some time. Expert mode: merging ion propulsion to assist air flow *deflamation(?) If you were able to get the ion propulsion and rocket engine to work symbiotically with the ion propulsion assisting in the control of detonation and deflamation. Love your stuff!
yes! I'm pretty sure this is it. I tried water electrolisys a few times and when you add salt it does turn brown, but it didn't work without an electrolyte (possibly to little current) so I'm not 100% sure.
its becouse the nickelstrips is made out of iron and only has a nickel plating. u need nickel rods made out of 100% nickel. the brownines comes from the iron in the nickel strips corroding whit the salt. Dont use nickel strips they aint nickel basicly.
I use this exact electrolyte a lot, my guess is the nickel strip is just nickel plated steel. If you can't get pure nickel anodes, welding rods for cast iron are often a good alternative.
A pretty good idea: you could cool the engine by taking the outlet of the fire extinguisher and get it through a copper coiled tobe around the engine ..

As I wrote in the last video, aluminium casting (sand casting with a 3d printed master, or lost PLA in plaster of Paris) could be a great and relatively easy way to make complex metal parts at home ;)
@@Penofhell I’ve wanted to sand cast aluminum parts for years now, thank god I saw your comment and reminded me. I need to go buy the materials to build the wooden boxes and sand and get other materials to build the furnace thing and make a couple crucibles! Thank you for reminding me just in time !
@@Penofhell thought sure you could use powdered cat litter (the super cheap kind that is bentonite clay mostly) and really fine grained sand to make "green" sand for lost wax casting and then just heat up the thing a bit more to get PLA to burn completely away? Plaster of paris will dehydrate at 350 degrees I thought becoming brittle and powdery again? (might be wrong on the exact temp, just remember that heating to drive off the water's OH that causes it to harden allows it to be reused all over again, and aluminum has a melting temp of 660º) but the bentonite and sand should handle much higher temps than that 660 of the aluminum so it can be over heated to make sure it flows and retains a lot of its heat, (heating the mold to nearly the temp of the molten aluminum seems like a good way to ensure no blocking happens along with avoiding easy to fracture points from some areas being more annealed while others are more crystaline in nature, but aluminum is much to low of a temp for his engine, I would suggest getting a pepakura making program and import that model for the 3D printer, so it can turn it into a tuck and fold 3D object then he can make it out of stainless sheet or maybe titanium if he can get a cheap source of scrap titanium sheet metal (they do heat tests and such on batches of titanium sheet so should be able to get the off cuts they used for this, from someone who worked there and grabbed it to sell it on ebay or something like I did with .020" thick sheeting, and he sent me a sample that was like .125") if using titanium then I can say it is not that hard to use a router attachment for a dremel, and chuck up 3mm or 1/8th inch thick titanium rod that you then drop down on the seams while spinning about 15,000 to 18,000RPMs to do friction spin welding though it does take some practice, even if you are used to normal stick welding or tig welding, but the welds are a bit better than even tig based ones, and you won't need to oven temper it when done. :)
Coat the parts FROM THE INSIDE. Your working against yourself coating the outside. You want your coating inside as then the pressure is pushing your coating into the part not off of the part.
It's sensical ! I would also say "add multiple fins on the external sides (like what we put on hot processors) to your design for the parts to cool down better
The TH-camr _Odd Tinkering_ uses electro Nickel plating for his restorations. Maybe he can tell you his source for the nickel solution Edit: on his second channel _Odd Experiments_ is a video on how to electro plate with Nickel. Maybe this helps you
Holy shit man. At first I wasn't a big fan of yours, but your quality has risen so much, so quickly, you're one of my favorites. Your ingenuity is unmatched and your stubbornness might actually lead to a scientific breakthrough with these 3d printed engines.
Joel , just to help out on safety w/ your jet experiments ( or anything flammable) so you dont catch you attic / house or rafters on fire , they have fire proof drywall covering , so you can build a dry wall box 3 sides on a table, (with cover top too) and coat the inside with it , its in in 5 gallon buckets forlike $150 . so you can have a 6-8 ft long x 4 ft experiment chamber, ( also have 1 side plexiglass sliding access door ), it will be fire resistant after you coat the entire inside , then you are safe.
INGETZGA! PLEASE! ONE MORE! Print the ceramic peices, glue them together with glaze or wire tie them together with copper or what ever you need to do, but then dip the whole thing multiple times into a proper graphite paint/ink! Then elctroplate as long as possible to get as thick as possible of a coating to make it essentially a completely encased single peice of copper with a ceramic core. @Robbertmurraysmith is always down for a fun project!
@@FzudemB molten copper is hard to make/sustain with out a decent homemade smelter and alot of room and lots of fuel, and its unlikely the fragile ceramic parts could handle the extreme temperature change across the part as it was dipped
He could also first glue the parts together with slip, plug any holes in the part and then cover several times with slip and put in the furnace in between. That would create several ceramic external layers that are entirely continuous, while leaving the inner dimensions unchanged (could also coat the inside if dimensions don't matter too much). Then electroplate the whole thing.
i also really think he should try the glaze, i bet he is afraid because it is glass, but once it is baked onto the ceramic it will never again come off. even if he shocks it with cold water, when it is hot ,it will only make a spiderweb of cracks in the surface but stay on the ceramic. no sharp edges, it's done in ceramic arts because it looks really cool. Also he can use glaze like a glue and bake the three parts together. He just needs some tungsten wire to keep them in position while baking them. metalplating with copper has no use in this case, because copper will grow in grainy little structures, when you electroplate, it will not become as tough as a copperplate no matter how thick. does anybody know how i can get into his discord? i have some ideas that might help him...
For the love of God Integza, I would put so much money towards a Kickstarter to raise money for some protective glass to do your experiments behind. I dont want to see you picking shrapnel out of yourself and your poor sister :c

Sealing ceramics is a pain in the exhaust pipe. You could try oven glue / cement on a soft metal seal disc. Spring load your screws. Ceramics temperature expansion is large. You could also redesign for self-sealing contact surfaces with oven glue or cement. Much better to ignite the fuel first and then add the oxygen. Then ramp up the feed pressure of both. Basically like every welder ignites their gas torch and avoids flare-ups and blow-outs.

now that you have loads of these little jets, you should build a schlieren photography setup to image the shockwaves and pressure waves coming out of the nozzles.
@@joziahserrano2507 not as difficult as you might think! If you put a burst disc halfway down a pipe and pull a vacuum on one half, you can pop the disc and the air will rush into the vacuum as a Mach 1 shockwave, with an expansion fan propagating the other direction. It’ll also mean we can see how turbulent the flow coming out of the nozzle is, and if it’s over/under expanded
@@TakeshiM you’re right there but since the amount of pressure and volume being moved would be hard to discern it would be hard to replicate it for a continuously produced combustion, and wouldn’t much allow us to actually see if the flow is under or over expanded... it might be better for him to use a aerospike nozzle for now to see if he can get continuous super sonic flow, and with experimenting with that he should be able to determine the right nozzle dimensions to make a conventional delaval nozzle that can maintain supersonic flow... though I’m no rocket scientist so that everything I said with a grain of salt lol
@@joziahserrano2507 I've only taken one class on propulsion systems which is the real reason I want to see him do this. But in any case, schlieren photography reveals even minute changes in pressure, so it can be used for more than just finding shockwaves. He could probably even see the vortex coming out of these vortex engines if he angles it right. Also, he was getting a good few seconds of continuous operation even in these tests, and with the slow motion camera that can be stretched out even more.
Your idea is not just good, it's exceptional! Imagine coating those rockets with tungsten, elevating their heat resistance to an incredible 3000 degrees Celsius. Harnessing the power of hydrocarbon fuels could propel this innovation to new heights. Picture crafting your own rocket, fueled by your engines - a venture that is not just amazing but truly inspiring, pushing the boundaries of what's possible in the realm of space exploration. This is my favourite video in your collection.As suggested i think you should use safety goggles everyone cares you bro(except that disgusting tomato lord!🤣🤣).
Even more amazing is not setting his house/apartment on fire: I mean, seriously, who is having flames shoot out several feet from the back of rocket engines in their attic? Wait, who test-fires rocket engines in their attic? @integza does! He's willing to burn down the house in the name of 3D printing rockets and their test firings. If that's a rental, I have to think the landlord wouldn't want to have a tenant do this, and if this is a place he has a mortgage on, the insurance company wouldn't want this going on either (well, certainly not the bank with the mortgage, because insurance will likely deny coverage over something like this: both insane and dangerous while arguably doing business in the form of youTube video production).
So I know this is old.. but I believe part of the problem could be the mating surfaces.. you should file, then stone, and then finally Lap the mating surfaces of the engine.. it will stop the blowouts.. pure mechanical seal
You should make a solenoid system for these bottles. In my opinion it might be a cool project and it would surely save you some time opening and closing these valves manually.

You should try making a vacuum chamber large enough for the printer. that way you can make the porcelite more dense. But make sure too high of a vacuum won't break capacitors.
Try using waterglass (sodium silicate) as a sealant/coating. It's a common refractory sealant. If you can't find it easily, you can make it with sodium hydroxide and sand/glass [or silica gel packets or silica kitty litter]. I'd use it on the joints, then dip the whole engine in it. NurdRage link- th-cam.com/video/Ip-jDuM25FE/w-d-xo.html One of its uses is sealing / joining firebricks.
@@SidneyCritic Correct! It's main use in the home used to be preserving eggs. It has many uses and is dirt cheap. You may be able to find it in an auto parts store in liquid form. I wasn't able to find it there in the US, so I bought the powder online and mixed it with water and boiled it to dissolve it. You may find it in a hardware store. Again, if all else fails, you can make it easily enough with sodium hydroxide and sand/glass// or with silica gel packets or silica kitty litter.
That's what I suggested in the previous video. Waterglass has a wide variety of uses, including the capillar watertightning of cements/bricks, passive fire protection, mineral-only adhesives. And it's not just a coating, it goes inside the ceramic material.
With this engine, you should use longer bolts so you are able to attach the pieces altogether. The idea is to use the bolts as supports and to tighten all the parts better.
I'd suggest you put an actual nozzel on your engine, right now you allow all the pressured gases to just disperse as they please. adding a bell nozzel or at least a cone shaped one should increase your thrust by a lot.
I like the idea of electro plating. I feel like most of your parts are fairly sturdy. Have you ever tried to just reinforce the rocket parts? Since the top keeps blowing out and the sides. Could you build a dual chamber zone that forces the leaks to the rear? Also ceramic is very brittle, it does great for heat. But its still ceramic and the forces exerted on those parts have to be insane. So maybe just bulk it up a a bit? Even if its oversized and underperforms, its 3d printed.
@@Icereaper15100 well 3D printing a mold its still 3D printing.. could be carved, the point, i guess, its to engeneer his ideas, he is already baking the ceramics and coating, clearly 3D printing as it is makes it super weak and prone to error. i guess he could male a mesh so strenghten it but i totaly agree with creative camera, he should try 3D printing the mold, just need invert the model, make 2 pieces, clean, glue, then cast some nickel(?) that was his choice for the coating so 😂 have a good day

I just came here to say that too! Up you go!
Funny.. i added a comment saying the same thing before I read this one.. it should also strengthen the parts since it is already used as a high temperature adhesive.
problem I see with this is you end up with either aerogel formation which has a much lower thermal survivability than people realize as it collapses, if you use the water and dry method you get silica gel which any water causes tiny fissures and liquid water outright causes it to split and explode like some ice cubes will when dropped in water, but for a very different reason. To get the effect he needs it needs to be held into a mold and fired to bring the SiO2 to full density, before being allowed to expand freely,
for a higher temp than both of these, I would suggest sodium alumina as it will collapse if done correctly into a solid transparent aluminum ie sapphire glass, with considerably higher melting temps, so alumina aerogel will last in higher temps too if you want a good insulator to keep the heat in, tougher exterior to keep leakage from occurring and all that jaz, but honestly I would love to see him cat up all the parts and use spin friction welding with titanium wire on a dremel on sheets cut to shape and make it out of solid titanium, as he would be on course for making rockets he could launch into space and have the first tomato free satellite network ;)
*there are a couple ways I have theorized to desalinate the sodium half of the silicate and alumina compounds with, with out an acid that actively pulls it free from the product leaving a pure substance against the surface, and then using laser tech to densify it, in layers, against the surface of an expanding conductive coated shape like say a round bottom flask grown around a flask shaped blown up balloon coated in graphite conductive paint to make it an electrode, that can be collapsed afterwards and withdrawn from the vessel, but it has not been tested yet.
@@ThomasAndersonbsf I don’t have time to debate you, but it’s obvious from so many claims there you have a lax understanding at best how any of that works.
@@ThomasAndersonbsf aerogel does use those elements but the method is incorrect for forming it. Try watching nile red's video on aerogel and you will get a better understanding on it.
Try adding fuel, igniting it, and then adding oxidizer, to prevent those explosions (hard start). You were right about the accumulations inside the engine and the spark plug, but I think that your mixing also is in play here. What happens when you add oxidizer first and then fuel is you get a stoichiometric mix of fuel and oxidizer in the chamber, which detonates just like any explosive.
Chemist here!
try to buy nickel carbonate (NiCO3), should be easy enough. And THAN convert it to nickel acetate by just letting the NiCO3 react with AcOH. Did it once and it worked perfectly. Just take care about the bubbling of CO2, so stirring and slow addition is necessary.
After that, just boil the water and acetic acid out. 120-130 °C should work. Use an oil bath if you can. Direct heat from a heat plate could cause problems :D
good luck!
EDIT: please be careful with the nickel ions since they are poisonous and wear safety goggles :D
EDIT 2: Use 100 % AcOH, or at least 25 % (should be easier to obtain). Or, I could send my leftovers to you :D

UGh. hmm.. it's going to be used as a rocket propellant? :-)

mr. chemist sir.... this isnt necessarily a chem question but maybe you'd have some insight... he was talking about using graphite paint to make the ceramic surface conductive... could graphite be mixed into the slip and then sintered onto the surface? or is the fact that graphite itself is used for things like crucibles an indication that there is no way that makes sense?
or even, now that i think of it... instead of painting the ceramic... finding out what the solvent was for the silver paint, getting more and diluting it, and dipping the parts in the diluted paint to slowly build up an even coverage that covers parts that paint wont reach
Isn’t the brown color from the reduction of the nickel ions?

Please wear PPE especially goggles your sister was wearing goggles. when printing parts an O-ring grove (RTJ ) and use a high temp o-ring. Mating flat surfaces together is hard - in pressure valves flat surfaces are machined and lapped to a mirror finish. if you are going to use flat surfaces and liquid gasket try using a spiral serrated / phonographic surface, or pick up a sheet of gasket material, its fairly inexpensively and easy to use.

Someone has probably already told you that copper plate is the foundation for a lot of metal plating including nickel. It looks like your copper was not covering the parts very completely though. Also the silver didn't look thick enough. I suggest more than one dip in the slip to build that up, then sinter it, then thick copper followed by thick nickel.
Remember to polish the silver as much as possible, same for the copper to get better adhesion of subsequent layers.
Also, of course you should look at what parts of the printed components physically blew open and make them a bit thicker.
Anyway, I hope this is as much fun for you to do as it is for us to watch!
I know this is a year old, but putting an electric valve to cut off the gases in case of an emergency should be on your list of todos. Love your videos!
Hey Integza! I had an idea as to why your nickel strips caused that brown solution. Usually, those nickel strips are sold for homemade battery packs and it is unfortunately common for strips to be advertised as 99% nickel but are actually nickel-plated steel. hope this helps!

Seeing the rocket run with zero leaks was the most satisfying moment I’ve ever seen on this channel
For propane systems there are safety relay valves that close when voltage is turned off. Highly recommended for this setup.
Use a spring to return your rocket to its starting positon! Then you can put a ruler on the side of your rail and measure how far back the rocket gets using the camera. Use the spring equation and you'll be able to actually measure generated thrust!
You could of course just buy a force gauge (not really expensive) and then just hang the device on the rocket engine. maybe you still need a pulley system, but why simple when it can be complex.
@@albusdumbledore271 The word you're looking for is, "complex," not, "difficult." It would be quite easy to do what the op is suggesting. Tedious? Maybe. Difficult? Not really.
Yes, this may seem impractical to you, but what makes you think that Integza is practical? The madlad literally stripped a linear slider off of his 3D printer because he couldn't wait a week for it to come in the mail! Lol
In any case, using the spring would also allow Integza to introduce Hooke's law to his viewers, so that's a plus.
P.s. I mean no disrespect by the way. I just feel like you were shutting down the op's idea without really considering what this idea would mean for Integza's content.
A bathroom scale fixed on it's side and a pole to push against it should give a close estimate of what type of force it will give off.
@@tremail564 You can also put the scale on the floor and have the engine thrusting upward. You'd have to measure the weight of the engine and subtract that from the scale's readings in order to get the thrust.
P.s. Integza's done this before, I believe.
Grammar Police yeah you can pretty much do this with a basic understanding of physics and a little bit of calculus.
Something that could help you not burn a hole in your table could be adding something like a quarter turn valve. You start with it open, and if something happens, you can close it immediately instead of turning the tank valve for 15 minutes

Since you are using ceramics, it might be interesting to use one of the glazes that are converted to metallic coatings in the kiln. Normally you keep them away from oxygen by placing the hot ceramic in hay or grass so that the smoke displaces the oxygen.
The fact he has no safety glasses on while his face is a foot (about 30cm) from the rocket while everything is under high pressure is just..... AHHHHHH
Yeah this is crazy. I'd be wearing a welder's mask with all that accelerant.

You should try casting the parts in metal using lost PLA casting using parts printed from your 3D printers. It's a new skill you can learn and explore that would make an interesting series to watch you learn the process.

The brown colour is probably due to NaCl you added.....the Cl makes the brown colour.....
yes! I'm pretty sure this is it. I tried water electrolisys a few times and when you add salt it does turn brown, but it didn't work without an electrolyte (possibly to little current) so I'm not 100% sure.
its becouse the nickelstrips is made out of iron and only has a nickel plating. u need nickel rods made out of 100% nickel. the brownines comes from the iron in the nickel strips corroding whit the salt. Dont use nickel strips they aint nickel basicly.
I use this exact electrolyte a lot, my guess is the nickel strip is just nickel plated steel. If you can't get pure nickel anodes, welding rods for cast iron are often a good alternative.

I think you should start developing a DIY metal 3D Printer and then use that to print a rocket engine. Or a beehive :D
As I wrote in the last video, aluminium casting (sand casting with a 3d printed master, or lost PLA in plaster of Paris) could be a great and relatively easy way to make complex metal parts at home ;)
@@Penofhell I’ve wanted to sand cast aluminum parts for years now, thank god I saw your comment and reminded me. I need to go buy the materials to build the wooden boxes and sand and get other materials to build the furnace thing and make a couple crucibles! Thank you for reminding me just in time !
@@Penofhell thought sure you could use powdered cat litter (the super cheap kind that is bentonite clay mostly) and really fine grained sand to make "green" sand for lost wax casting and then just heat up the thing a bit more to get PLA to burn completely away? Plaster of paris will dehydrate at 350 degrees I thought becoming brittle and powdery again? (might be wrong on the exact temp, just remember that heating to drive off the water's OH that causes it to harden allows it to be reused all over again, and aluminum has a melting temp of 660º) but the bentonite and sand should handle much higher temps than that 660 of the aluminum so it can be over heated to make sure it flows and retains a lot of its heat, (heating the mold to nearly the temp of the molten aluminum seems like a good way to ensure no blocking happens along with avoiding easy to fracture points from some areas being more annealed while others are more crystaline in nature, but aluminum is much to low of a temp for his engine,
I would suggest getting a pepakura making program and import that model for the 3D printer, so it can turn it into a tuck and fold 3D object then he can make it out of stainless sheet or maybe titanium if he can get a cheap source of scrap titanium sheet metal (they do heat tests and such on batches of titanium sheet so should be able to get the off cuts they used for this, from someone who worked there and grabbed it to sell it on ebay or something like I did with .020" thick sheeting, and he sent me a sample that was like .125") if using titanium then I can say it is not that hard to use a router attachment for a dremel, and chuck up 3mm or 1/8th inch thick titanium rod that you then drop down on the seams while spinning about 15,000 to 18,000RPMs to do friction spin welding though it does take some practice, even if you are used to normal stick welding or tig welding, but the welds are a bit better than even tig based ones, and you won't need to oven temper it when done. :)

The testing was the most metal thing I've seen in a while.
Coat the parts FROM THE INSIDE. Your working against yourself coating the outside. You want your coating inside as then the pressure is pushing your coating into the part not off of the part.
It's sensical ! I would also say "add multiple fins on the external sides (like what we put on hot processors) to your design for the parts to cool down better
You not only prevent it from even going into the pores at all but you also have a much lower surface area to cover.
That would only work for the combustion chamber, in the throat and nozzle it would erode away
@@thingymuhbob if it were to erode the entire concept couldn't work, as the body itself would erode

Joel , just to help out on safety w/ your jet experiments ( or anything flammable) so you dont catch you attic / house or rafters on fire , they have fire proof drywall covering , so you can build a dry wall box 3 sides on a table, (with cover top too) and coat the inside with it , its in in 5 gallon buckets forlike $150 . so you can have a 6-8 ft long x 4 ft experiment chamber, ( also have 1 side plexiglass sliding access door ), it will be fire resistant after you coat the entire inside , then you are safe.
INGETZGA! PLEASE! ONE MORE! Print the ceramic peices, glue them together with glaze or wire tie them together with copper or what ever you need to do, but then dip the whole thing multiple times into a proper graphite paint/ink! Then elctroplate as long as possible to get as thick as possible of a coating to make it essentially a completely encased single peice of copper with a ceramic core. @Robbertmurraysmith is always down for a fun project!
Could also try dipping it in molten copper (if he has the possibilities for that)
Or use spray welding
@@FzudemB molten copper is hard to make/sustain with out a decent homemade smelter and alot of room and lots of fuel, and its unlikely the fragile ceramic parts could handle the extreme temperature change across the part as it was dipped
He could also first glue the parts together with slip, plug any holes in the part and then cover several times with slip and put in the furnace in between. That would create several ceramic external layers that are entirely continuous, while leaving the inner dimensions unchanged (could also coat the inside if dimensions don't matter too much). Then electroplate the whole thing.
i also really think he should try the glaze, i bet he is afraid because it is glass, but once it is baked onto the ceramic it will never again come off. even if he shocks it with cold water, when it is hot ,it will only make a spiderweb of cracks in the surface but stay on the ceramic. no sharp edges, it's done in ceramic arts because it looks really cool. Also he can use glaze like a glue and bake the three parts together. He just needs some tungsten wire to keep them in position while baking them.
metalplating with copper has no use in this case, because copper will grow in grainy little structures, when you electroplate, it will not become as tough as a copperplate no matter how thick. does anybody know how i can get into his discord? i have some ideas that might help him...

Sealing ceramics is a pain in the exhaust pipe. You could try oven glue / cement on a soft metal seal disc. Spring load your screws. Ceramics temperature expansion is large. You could also redesign for self-sealing contact surfaces with oven glue or cement. Much better to ignite the fuel first and then add the oxygen. Then ramp up the feed pressure of both. Basically like every welder ignites their gas torch and avoids flare-ups and blow-outs.
Video idea: try to build a hilsch vortex tube. It is a tube that takes compressed air and puts out hot air on one side and cold air on the other side. I think it is a very interersting phenomenon.

now that you have loads of these little jets, you should build a schlieren photography setup to image the shockwaves and pressure waves coming out of the nozzles.
Well, it’ll be a bit of a pain to get super sonic flow to achieve those shockwaves
@@joziahserrano2507 not as difficult as you might think! If you put a burst disc halfway down a pipe and pull a vacuum on one half, you can pop the disc and the air will rush into the vacuum as a Mach 1 shockwave, with an expansion fan propagating the other direction. It’ll also mean we can see how turbulent the flow coming out of the nozzle is, and if it’s over/under expanded
@@TakeshiM you’re right there but since the amount of pressure and volume being moved would be hard to discern it would be hard to replicate it for a continuously produced combustion, and wouldn’t much allow us to actually see if the flow is under or over expanded... it might be better for him to use a aerospike nozzle for now to see if he can get continuous super sonic flow, and with experimenting with that he should be able to determine the right nozzle dimensions to make a conventional delaval nozzle that can maintain supersonic flow... though I’m no rocket scientist so that everything I said with a grain of salt lol
@@joziahserrano2507 I've only taken one class on propulsion systems which is the real reason I want to see him do this. But in any case, schlieren photography reveals even minute changes in pressure, so it can be used for more than just finding shockwaves. He could probably even see the vortex coming out of these vortex engines if he angles it right. Also, he was getting a good few seconds of continuous operation even in these tests, and with the slow motion camera that can be stretched out even more.
Your idea is not just good, it's exceptional! Imagine coating those rockets with tungsten, elevating their heat resistance to an incredible 3000 degrees Celsius. Harnessing the power of hydrocarbon fuels could propel this innovation to new heights. Picture crafting your own rocket, fueled by your engines - a venture that is not just amazing but truly inspiring, pushing the boundaries of what's possible in the realm of space exploration.

He's willing to burn down the house in the name of 3D printing rockets and their test firings. If that's a rental, I have to think the landlord wouldn't want to have a tenant do this, and if this is a place he has a mortgage on, the insurance company wouldn't want this going on either (well, certainly not the bank with the mortgage, because insurance will likely deny coverage over something like this: both insane and dangerous while arguably doing business in the form of youTube video production).

For those you don't know Basil Brush is a children/family fox puppet based on Terry-Thomas (who played bounder/cad types) and built by Peter Firmin (Smallfilms).
Noted for his catchphrase of BOOM BOOM!

Basil is a true g
His lack of safety goggles during the ignition tests is ridiculous.
I dont think the younge ppl these days will evan knw who basil brush is lol
And using your hand as a muzzle your pet dog is known as Basil Brushing your dog. 🤣🤣🤣
Yes the irony is not lost on me
@Integza beware of those spam bots roaming around your comment section.
If your insurance company finds these videos I think you're gonna be asked a few questions...
I genuinely love the dodgy'ness of your experiments, keep up the good work.
There aren't a lot of things cooler than seeing someone work through a problem, one individual variable at a time, and the explosions just make it more badass. You got me, I'm subscribing. Stay safe!
You should try making a vacuum chamber large enough for the printer. that way you can make the porcelite more dense. But make sure too high of a vacuum won't break capacitors.
A vacuum strengthened ceramic will withstand a higher tensile wrap to further strengthen a ceramic part against fracture.
I love that you involve your sisters on your projects.
Try using waterglass (sodium silicate) as a sealant/coating. It's a common refractory sealant. If you can't find it easily, you can make it with sodium hydroxide and sand/glass [or silica gel packets or silica kitty litter]. I'd use it on the joints, then dip the whole engine in it. NurdRage link- th-cam.com/video/Ip-jDuM25FE/w-d-xo.html One of its uses is sealing / joining firebricks.
I think sodium silicate is in auto crack repair fluid that you pour in the radiator. Here it's called Irontite.
@@SidneyCritic Correct! It's main use in the home used to be preserving eggs. It has many uses and is dirt cheap. You may be able to find it in an auto parts store in liquid form. I wasn't able to find it there in the US, so I bought the powder online and mixed it with water and boiled it to dissolve it. You may find it in a hardware store. Again, if all else fails, you can make it easily enough with sodium hydroxide and sand/glass// or with silica gel packets or silica kitty litter.
Make your own from crystal kitty litter/silica gel(same stuff) and sodium hydroxide
That's what I suggested in the previous video. Waterglass has a wide variety of uses, including the capillar watertightning of cements/bricks, passive fire protection, mineral-only adhesives. And it's not just a coating, it goes inside the ceramic material.
You should put the whole rocket engine in a bucket and fill it up with cement/ceramic, that would make it not leak anything :)
Ye dip the whole part and the gaz pipes with it because i guess some leaks come from the pipes
That would make it too heavy and it wouldnt get thrust
With this engine, you should use longer bolts so you are able to attach the pieces altogether. The idea is to use the bolts as supports and to tighten all the parts better.
Don't give up man ☺️ I'm sure you'll build a successful engine next time
Can't wait to see it
I'd suggest you put an actual nozzel on your engine, right now you allow all the pressured gases to just disperse as they please. adding a bell nozzel or at least a cone shaped one should increase your thrust by a lot.
Video idea: mount it on a remote control car and see how fast it can go
Or a scale first
Imagine de car if the engines
"and see how fast it can" explode
The engine would most likely set the rc car on fire within a few seconds, if not exploding it.
probably wouldn't work those engines don't seem to have much thrust he would need a no resistance roller
I like the idea of electro plating.
I feel like most of your parts are fairly sturdy.
Have you ever tried to just reinforce the rocket parts?
Since the top keeps blowing out and the sides.
Could you build a dual chamber zone that forces the leaks to the rear?
Also ceramic is very brittle, it does great for heat.
But its still ceramic and the forces exerted on those parts have to be insane.
So maybe just bulk it up a a bit?
Even if its oversized and underperforms, its 3d printed.
why did you structure this comment like a poem bruh
When your fuel hose makes more thrust than your rocket engine, you know you've got some issues.

I think a video on the effectiveness of safety glasses would be nice.

19:21 “Oh jesus christ we just frozen our ceiling” is one of the best exclamations ever

@@evanjohnson3115 holy crap your right
im so so so happy that i found your channel so damn early on, since watching you grow with these projects is truly a sight to behold man
I thought that was a barn, not your attic. You just now thought a fire extinguisher might be a good idea? :P
How lucky I am that you came up in my algorithm, I don't know why you hadn't before. All your vids have been fantastic!
With your printer make some molds for casting the metal rocket engine...so won't explode and leak
👍👍
Brass casting
up
But then it's no longer 3d printing the parts which goes against the theme of the videos which is 3d printing a rocket
@@Icereaper15100 well 3D printing a mold its still 3D printing.. could be carved, the point, i guess, its to engeneer his ideas, he is already baking the ceramics and coating, clearly 3D printing as it is makes it super weak and prone to error. i guess he could male a mesh so strenghten it but i totaly agree with creative camera, he should try 3D printing the mold, just need invert the model, make 2 pieces, clean, glue, then cast some nickel(?) that was his choice for the coating so 😂 have a good day
