It's finally happened, just like every other STEM KZfaqr, 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!

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.

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

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.

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

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 🍅💀

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.

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

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

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

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

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

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

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 !

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

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

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!

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

The work this man does is next level.

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

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.

For being a Jet Turbine powered skateboard, it's amazingly slow. Lots of coloured flames, noise and heat, not much actual thrust though, amazingly so. It's a firework.

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

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.

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

Integza please create Steam fires underwater jet engine

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.

Great torch brazing job, im impressed

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

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!!!

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

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!

Wow! That flame is BIG!

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

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

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 :)

im in awe how u did this!

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

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!

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

Wow. Amazing! Job well done man. 👏🎉

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.

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!

I'm curious about the land speed record barrier. Most recent record holders are essentially jets without wings. The barrier comes from a quadratic drag coefficient. If you could demonstrate this it would be awesome. If you could overcome this it would be boss. If you could break the record it would be epic. I've always wondered if a laser leading the vehicle body might help. You might need a bigger skateboard though. If nothing else it would be another way of destroying tomatoes to add to your bat belt.

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

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 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

You for sure have skillz for a custom jetpack design

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.

I think a cool addition to this could be using a Pi Pico or other micro-controller to turn a single potentiometer into a dial for both the amount of propellent introduced, as well as the speed of the inducer.

Love your videos man!

I just watched some of your works and it was a pretty nice piece of invention. I also notice if you just wanted to add some heat absorber something like ''RADIATOR'' it will last for an hour or more than that

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!

I would have burned myself so many times doing this hehehehe

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

wow that is amazing

You said you aren’t great with metalwork but that jet engine would make one hell of a forge burner. Might be a fun experiment to see how fast you could melt steel with that thing!

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

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.

"Although I struggle with English, I wanted to share an idea with you in this comment. Have you considered using nichrome wire to create a captivating jet engine effect? You could install a jet fan and arrange the nichrome wire in a circular pattern. By supplying electricity to the nichrome wire, the airflow from the jet fan would fall onto it, resulting in a realistic jet effect. Additionally, incorporating some fuel could potentially enhance the overall outcome. I hope you find this suggestion helpful and exciting. Keep up the great work on your channel!"

8:54 LOL, when you were doing the soldering at like 2:25 i was thinking about how i wasn't sure if they were gonna hold because of the heat. that's so funny. thanks, i've always wanted to see that happen

Amazing as always. Your spot welder is really impressive!

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?

wow this is everything

Good job never give up

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

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

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!

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.

Video Idea: it would be so cool to see that jet engine on a small boat! Since the friction slows the skate down so much, water might be the key to unleash the true power 👀 Imagine having it to rc stear too!

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

Build a Rotor-Stator compressor type at the front with a BIG ROTOR fan as first stage ( With you 3D printers it will be a peace of cake), it will increase the amount of air significantly and let a part of that air bypass the engine. So you get a High-Bypass engine. The second advantage is that you can use this Bypass Front ( or FAN ) air in a ducting around the entire engine so it will cool down the exhaust pipe.

Great project !!!

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

Video Idea: try redesigning the compressor stage to resemble an automotive centrifugal supercharger. I've always wanted to see if a 3D printed compressor wheel could actually generate pressure, and since the intake would be perpendicular to the thrust all the forward thrust would be from the jet engine.

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

Your metal work is quite good

I have a few ideas on how to further improve the engine. If you look at your footage, you can see that the engine gets very hot, almost white hot. You could make a bypass fan on the front and a shroud to channel air over that hot area to help keep it cool. Also, you could re accelerate the air after it is ignited to make it go even faster. Just a few ideas to consider. Great video!

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.

4:48 5:05 you cant believe your PROFESSIONAL, store bought, spot welding machine is actually working?? . ya... who would have guessed that a dedicated spot welding machine would work!!?!?!?!?? its like saying "wow, my Lincoln electric MIG welder is really good at welding!!!"

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

I would love to see you do a project involving ionic thrust, how quickly and efficiently you just made a mini spot welder gives me hope! Be careful though, electricity is very spicy.

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

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

That unemployed friend on a Tuesday afternoon:

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

0:19 *WHO IS THIS MAN, AND WHAT HAS HE DONE WITH INTEGZA?!* I can't accurately describe in this comment the noises I made when I saw that shaved face, but I can at least say that they were many and pained and filled with despair

Spot welders can be made with broken microwaves parts, at any junkyard or used one, you can grab them for super cheap, take out the metal body and look for the big squared shaped inductor, I suggest you short circuit the big capacitor before removing it thought, use non conductive gloves if you do so. Plus. when you don't need the spot welder, you can use the inductor to make an super concentrated metal heater with some coper tubing and some elbow grease, you will have an inductor heater that heats any metal very easily.

I respect your style

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

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

Theme for next video: Build a small device, possibly incorporating a jet engine, big ballon, a few GoPro’s and launch this box so it rises to the edge of our atmosphere/space and to take a 360 view picture

This channel is the perfect blend of science and entertainment!
