It's finally happened, just like every other STEM UKpostsr, Integza has realised he needs a spot welder... and proceeds to make one himself.

Filming idea: When you want to record a shot from downrange of an jet engine, use a mirror. This lets you keep the camera equipment out of the line of fire, while only risking a much cheaper mirror.

Came for the Jet build, stayed for quite possibly the most rudimentary spot-welder I have ever seen. Well played.

11:57 The effect how the engine nozzle shrinks due to the hot air is amazing!

Wow, that thing has some beans! Pls let me put it on a plane

Video Idea: Make a thin tin sheeting metal plane that uses the spot welding and a rc prop or make your own engine for it, either way, I think it would be really cool to see something like that Love the content, even if it is only every couple weeks.

I know I’m not the first one to say this but, wow! I was extremely impressed with the self made spot welder! Insanely good job, been loving the vids!

I absolutely adore the shear insanity it takes to innovate solutions on the fly like this. Never change.

This is so insanely cool dude! Now i want my own jet skateboard hahaha

Pro tip, when you cut fuel in your engine, you’ll want to spin the compressor fan for a few moments after to run air through the engine. This helps it cool down and prolong the life span. Also if you want to film inside your engine and not burn the microphone, put a mirror in line with the exhaust port and angle it with a camera so you don’t burn the camera. The exhaust is pointed at a mirror

Quick note: Not all jet engines are the same. For example, the one you used in the beginning of your video is a high-bypass, turbofan engine. This means that the vast majority of thrust is NOT produced by the engine exhaust, but by the fan at the front of the engine.

Love the idea. Love the video. Great work!!!

Video idea : using your welder and new engine to make a rc rocket, one that has controllable gas output! Maybe even controllable stages? Remeber! Tomatoes are disgusting 🍅💀

Why not try attach this to a lightweight foam glider and see if it'll fly!

Hands down this is the best homemade jet engine I ever seen, keep going

You make it look so easy to make a jet engine, really like your content keep up the work

I love how this has slowly shifted from a 3D printing channel to becoming more like a full on Hacksmith type channel.

9:00. Next time use a mirror placed in front of the exhaust at an angle so you don't damage your equipment. Awesome video !

The work this man does is next level.

Wow. Amazing! Job well done man. 👏🎉

Using sheetmetal and your spot welder now, you can try to implement a few different nozzles for this which would greatly affect the thrust products. 3D printed dies also can be used to bend sheetmetal. I guess it's time build a thrust set-up to characterize your homemade jet engines!

Integza please create Steam fires underwater jet engine

Great project !!!

Love your videos man!

I love seeing how much you've improved with metal fabrication, that home made spot welder is beautiful

It looks like the engine would benefit from some sort of restriction at the exhaust as to increase the escaping gas velocity, assuming you can keep compression high enough at the intake. Some sort of a CD Nozzle should be pretty simple if you made out of a can or something, especially with that spot welder.

That unemployed friend on a Tuesday afternoon:

Amazing vid u deserve so much more subs for all that effort

"The dremel tool: rarely the best option, but always a good one" -Louis Weisz

So…next you need to add a bypass to it to allow most of the air taken in to bypass the combustion and mix back in afterwards. This will increase the thrust produced and is why turbo jet engines are designed so. Also lowers the noise

This isn't an ideal commitment for your channel it's a thanks for all tha hours you put into your work you have gotten me to use my 3D printers alot more instead of using them for paper weight so thanks keep up tha great work.

wow that is amazing

I’m genuinely surprised at how smooth the manufacturing process for literally everything was, from the body of the engine to the spot welder, like how

..one step closer to Maaars 🚀🚀 Excellent Jet Engine Joel!

U're a genius! Ever dreamed to build that! Congrats!

im in awe how u did this!

I can't help but feel like a nozzle would make a world of difference to the thrust output

Let's go! One of the few youtubers I get excited to see a notification from.

The spot welding was creative but that combustion chamber was big brain. Like butane through a circular tube. Epic. I’m crazy impressed

8:49 Integza, those bubbling welds scared the crap out of me!!! I’m glad your safe mate!!! Video idea: put your jet engine inside an RC ME 263. Or make another engine and put both of them in an RC ME 262!!!

8:53 That pop was dangerous! 11:32 The bowl popped because you only heated the bottom of it (the upper part, as it was standing with its opening facing downwards) and so it expanded unevenly. That put strain on the glass. You may know, glass really doesn't like that. So it popped while settling while cooling down again.

Good job never give up

Great torch brazing job, im impressed

Amazing as always. Your spot welder is really impressive!

Video Idea: Make some way to measure thrust output and put all the engines you've built over the years Head to Head to see how much your designs have improved!

You should also try just the fan. So you can see how much the combustion adds tho the thrust

Video idea: build a testing rig in order to compare the various rockets parameter and start a community design contest to find the optimal one.

Yes, that's cool and everything, but where is the mustache?! 😱

God bless you bro for making this more simpler🙌🙌🙌🙌

Rare motocompression type of jet system. Nice channel, by the way!

Really good video, its amazing to see your progress from the earlier ones. Never giving up and open to make mistakes and learn from them. Spot welder almost stole the show, could have been a short on its own too ;) Parabéns!

My idea for a video: Put this kind of Jet engine on a rc plane. Maybe you could 3D print it or make it out of foam! I would love to see it!

Man you are amazing !!!

Congratulations for the creativity! Sick-looking spot welder you got there...

You should try to make an underwater rocket engine. It would be a good next step to get to mars, considering there is no air in space. You could use electrolysis to get an oxygen and hydrogen mixture as fuel, or you could just buy an oxygen tank and continue to use butane.

Next Crazy idea would be... To build a rocket that can carry payload and maybe with that we can place our own little satellite :P And hey I'm a software developer so please let me know if i can help with the satellite

This type of jet does not slow the exhaust down in order to run the compressor, absolutely wonderful design!!!

I both love watching and falling asleep to his vids in the nicest way possible

I would have burned myself so many times doing this hehehehe

Love your channel, I am glade your safe... drilling, cutting/welding on a "empty" fuel tank has its dangers even when there small (don't want you to lose an eye... that would suck, but would land you a few more views the wrong way.) The tank may appear to be empty... but it may have fuel residue and air.. possible an explosive mix... If you can fill it with water or an inert gas after it is empty then do the Hot work its an easy step that in future may save you from injury.

wow this is everything

Wow... This is really amazing, I've been dreaming to be just an inventor since I was a kid, and it's actually becoming a reality

The sound of that little engine is insane! Also the sound when it ignites! Nicely done sir!

Integza is the man that managed to do all sort of experiments everyone wanted to do as a kid but couldn't, really, I love the content

Integza, I think a theme for a future video should be top 10 things you can print with your 3D printer! My kids are wanting to do STEM projects this summer so I am already trying to come up with a list of things to do with them. Cheers!

Really nice and creative ❤

make an afterburner for the jet engine, that would be sick.

Put a very small jet engine on a boomerang. I'll supply the boomerang.

I am genuinely impressed with your pliers spot welding setup. Also I was curious when I saw you joining the two canisters together with solder, when the solder joints would begin to fail. I saw them bubbling up quite a bit in the initial ignition testing. Perhaps you can figure out a way to make a little plier welder of some sort to get a better joint. All in all very cool project.

I really like this video I think another great idea would be to make a revised version of this jet engine with a different shaped end piece to expand the gas more expansion for the gases

I can't wait to see what you can do when you get some more metalworking knowledge and tools. This is just the start and I'm going to be following you all the way 🔥

Do a episode where you make more homebrew equipment like the spot welder. I would love to see other tools like this featured! On a side note: Can you spot weld a tomato?

I love your videos!

Your great guy young man, keep going through cross whatever happen step by step never give up in life, we need to learn for our life when we was born to die in the world so many things.

Video idea: You should make a rocket engine using items from around the house. May I suggest hairsprays fuel.

After having seen many of your engines in action, the next logical step would be controlling the burn better. Up until now your fuel and air mixture has always been controlled analogically. It is time to bring your combustion to the digital era! I am thinking about the rocket version of EFI ;-)

Fun video. Really enjoyed it. I need that 3D printer. 🙂

Wow! That flame is BIG!

Love to see you go big like big scale jet engine and see how much thrust you can get

As someone who takes thermodynamics, I can say that you summed up the theory very well, would've appreciated to see an explanation of how expansion and compression is isentropic (meaning zero change in entropy, or just incredibly efficient), and heat addition and removal is constant pressure, and unfortunately it's hard to call this a jet engine, more or less a ducted fan with an overpowered afterburner. If you really want to make this a jet engine, you'll have to create the correct geometries so that the fuel and air can be ignited with a constant pressure, and the compressor, and more specifically your expansion process can follow a more isentropic curve. Also, your compressor isn't much of a compressor really, it just accelerates air and then heavily restricts flow, which just increases entropy really. If you want to make this more efficient, and potentially fly something, and believe me I've given this type of heat engine a lot of thought you need to do 4 things: - Compressor, make a 3d printed in your case, more preferably with titanium sls, or milled titanium, with multiple sets of blades (i'd recommend just copying blade geometry from existing turbojet designs) with an increasing inner diameters so that air is smoothly compressed which will greatly reduce your entropy generation, and achieve a much higher pressure. Also, make sure the tips of you blade do not exceed mach 0.9, I ran the calculations earlier and with a 10s 400kv motor, I think that made a blade diameter of like 150-200 mm, this of course would be the most efficient set up for isentropic expansion - heat addition, id recommend changing what type of fuel is injected and how it is, personally i'd recommend isopropyl,99.9 percent because it is cheap and easy to acquire but has a very large energy density, similar to kerosene, but burns at a lower temp. Youll need to create a way to push the isopropyl through small holes to atomize it, so it can combine perfectly with the air and allow for a constant pressure heat addition (which you'll also need to model geometry for), and increase efficiency - Expansion, this really is just all geometry based, and with your knowledge of rocket engines you should be able to figure out how to turn high pressure zero velocity air into low pressure high velocity air. Good luck I hope you revisit this, this is a very cool project and the engineering behind jet engines is very fascinating, also screw tomatoes also fun little bit of thermodynamics: Work (net) of a breyton cycle turbine is equal to Qout - work (compressor), what you're doing here is maximizing Qout by making all the compressor work be from the electric motor

so glad to see you posting more about this kind of stuff! i’ve been designing my own electric jet engine. i hope you wouldn’t mind if i use some of your ideas!

The burner on my fogg billet forge is VERY similar in function. Badically a blower feeding air into the combistion chamber that has a second valved feed line for propane. Cool :)

Amazing one spool jet engine 😌

I think the coolest thing about this is the sound. It sounds amazing

Have you ever thought about combining one of your rockets to an RC or even better you're own 3d car? Would be so cool to see this particular engine on one

Wow you are amazing 🤩

Your metal work is quite good

Swap the electric motor for an impeller spun by the exhaust of secondary rocket engines to make the ultimate turbo-rocket engine! Maybe try running those CO2 canisters as the secondary rockets to prevent the turbine from instantly melting, while getting the main impeller to an insanely high speed.

I think you should make custom fuel for the turbo jet and see which mixture produces the most thrust for the jet

An amazing video!

I respect your style

Video idea: for a better way to power the jet. Add a nozzle to the end to control the jet blast better and make it more stream lined. Also you might want to make a bigger fuel cell and upgrade the intake jet so you have a better air flow. You are off to a great start and can achieve what ever you set your mind to. Congrats and have fun.

Video idea: you could try making a d nozzle to use thrust vectoring on an rc plane like on real planes !

Absolutely brilliant once again. Thank you so much Sir. Your content is truly appreciated. I like the hands on approach to the projects. I'm a welder,machinist, mechanic, and union carpenter. Just not a scientist..DAMMIT, I'm trying though. Thanks again Sir.

Love the science of your videos. Suggestion: Maybe prototype a model size rocket like the flacon 9 that has its own landing gear upon landing!

You've now done a jet engine...what about a pulse jet engine?

Thats's quite brazen 🔥

8:49 careful, your soldering material is melting (where you fixed the fuel inlet tube to the housing.

Nice project. 👍👍👍

I kinda expected him to canibalise a tazer or something crazy like that for the cumbustion generation /sparker. This guy has some awesome content. Keep it up m8 love the channel
