@@benadams5557 The UV-C that comes off a welder doesn't care about skin colour it just burns it all the same. Slightly different from the UV-A and UV-B that sunlight has within our atmosphere. It is often used to kill bacteria and virusses and will even burn your eyeballs which is what the mask is for (it isn't the brightness that gets you)
@@benadams5557 well I'm not works in there but I'm definitely sure they'll used clothes when welding I don't know if it's matter as much if to them because all of them ethier torch or stick welding
Welding tip: Weld in VERY TINY cursive e's (like loops) along the weld line very slowly (a single 0.5cm loop every 1.5 to 2 seconds) and sand down your welds after, because the lumps on top actually make it weaker by allowing cracks to form. With enough practice, the welds can be as strong or stronger than the surrounding metal.
Unnecessary with wire feed. All he needs is to learn the correct heat setting for the thickness he's attempting to weld, and the correct hand speed as he's welding.
You can 3D print the nozzle out of metal. If you'd like, I can contact Arizona State University. They can print out of TITANIUM!! I'll get it shipped out to you. All they need is your designs.
Titanium would be very rapidly consumed, unfortunately. Inconel, though... that will work. And AFAIK it is relatively common (insomuch as metal printing at all is...) to print Inconel.
Hey, I just had an idea for your next attempt at sealing ceramic parts. You should try to vacuum the parts when they are submerged in a fire resistant resin. It will force all the resin into the porous structure of the nozzle and hopefully seal it much more effectively than you've been able to in other videos.
Hey this is pretty good. I went the other way, and thought he should autoclave them in the resin and bake them a second time to get the same effect but by pushing it in, instead of pulling it through.
That could work. It might be difficult because rockets tend to turn anything fire resistant into something burnt, but I don’t think it’d be worse than pure ceramic.
@@IcespherePlaysGames I thought that's how we all did it? Like sure there's a nerd somewhere keeping track of the math and saying "It checks out," but for the most part we're just slamming different fuels through different nozzles and blasting off until we hit the mun.
as a professional welder im just watching the segment and man im proud of you for having on the appropriate protection jacket. also as a first try dude that looks amazing your fine. if you want to show welding on screen youll need to get a see through red film . things like stainless your gonna tig weld. youll like tig welding the most
@@clydecraft5642 I mean he's not too far off. Some of his hybrid tests in the last video didnt fair too well. The issue is the compression he builds up. Compression makes the fuel burn faster, and he was already having compression issues.

@@quasimotto6314 You can get a force gauge for about the same price as a digital scale. And idk if he has any connections to a school, but usually schools have dozens of them.

this is exactly what i was bout to comment.. its what my weld instructor told me when i first started my boiler makers apprenticeship.. believe me.. this saying alone is what gave me the strength to push forward on those days where everything i did just seemed to go wrong :)
The mystery metal might be the solder eeking itself into the chamber. If it melts with the torch you used to solder then you know that's your culprit. Hope this helps
@@Greeev just re-watched you are correct. just not sure if it's solder, since if it were melting then surely it would blow the back out, after melting enough.
The metal is an aluminum-silicon alloy produced from the decomposition of the ceramic at high temperatures. The ceramic is roughly 10% aluminum and 20% silicon.
Video Idea: you should convert these prototypes into a fully working rocket that can bring payload into space. It would be very cool to have a 3d printed powered rocket.
Electron's engine Rutherford is 3D printed en.wikipedia.org/wiki/Rutherford_(rocket_engine) and it uses an electric pump fed engine instead of a regular turbo pump to accelerate the fuel and oxidizer into the combustion chamber. en.wikipedia.org/wiki/Electric-pump-fed_engine
I am from iran integza and few days ago i look for videos about hand made jet engines and i find your chanel and i can say you and your chanel are the best .be safe and happy❤️
Thank you for the epilepsy warning before the welding segment. Too many people leave that out. Also, remember "A grinder and Paint make me the welder I Ain't"
You should also weld a plate to the side of the front to directly attach the nozzle the rocket so you can push the rocket engine to its absolute limits
Always a good idea to test as many parameters as possible on any given run. Having your 'sled' or mounting bracket attached to a resisting spring or weight and pulley, to give you some kind of reading of thrust. This accompanied with your great high speed camera should give you more bragging rites.
To all the people help this message get through so he knows about metal fume fever, it's heavy metal poisoning and probably the worst you can feel without dying
I remember I found out about that when I accidentally gave it to myself once. I was brazing a component that I had not been informed was anodized. It was one of the worst things I've ever felt to this day. By the time I heard the metal start to sizzle it was to late and I had already inhaled the fumes. You have to be super careful with metals that have been coated when doing hot work!
Only galvanized/zinc plated steel poses a real dangersince it's caused by zinc oxides, and it still takes a decent amount of welding in an unventilated space to take effect.
wiki: Metal fume fever, also known as brass founders' ague, brass shakes,[1] zinc shakes, galvie flu, metal dust fever, Welding Shivers, or Monday morning fever Unrelated to disco fever
Did that once in cut off jeans, caught myself on fire. Got it out quick enough for no injuries though. Lets not talk about the rather large scar on my foot from welding barefoot though.
There are two possibilities for the metal. As you say, one is Al from the fuel grain. The other is you are running a seriously reducing flame and you are pulling oxygen out of whatever ceramic is forming the nozzle. In either case you are running well oxygen poor, and it loosing you energy. I might suggest going for lower surface area on the grain so your oxygen flow gets closer to fully burning out the available fuel. In either case, I would guess the aerospike is probably a no go, there is effectively no material that can survive with so much heat flux all around it. If you haven't already, check out Tim Dodds video on aerospikes, that cooling issue is no joke. The bell nozzle has possibilities though.
@@VerbenaIDK He almost certainly isn't - the mass of oxygen needed for complete or near-complete combustion is quite a lot. I agree that the aerospike nozzle is a no-go - I made a normal bell nozzle out of 1600 C resistant concrete and the ceramic itself was melted into a glass. in order to survive for just a short time, the nozzle material must either have enough thermal mass and conductivity to absorb some of the heat for long enough, or have a ridiculously high bulk melting point (graphite or tungsten spring to mind). IMO, none of these materials, except maybe a refractory metal or alloy like inconel can have the strength and temp resistance to support an aerospike for any length of time. The only other option is actively cooling the nozzle, maybe with water, which could work with a metal nozzle.
@@robbiejames1540 i would try just using the oxygen itself to cool it inst that efficient, hr could try to use a liquid fuel and try to use that to cool the engibe, but then you have the problem that aerospike is an aerospike so yeah best option is a bell nozzle
You should really design a test stand capable of measuring the force produced by your rockets. I feel like it really wouldn't be too hard to add a spring-based force sensor to your current stand that pulled the carriage forward opposite of the force of the rocket to accurately measure the force output. I also feel like it would make a really cool video if you went back and tested some of your previous rocket designs on this test stand to visualize the progress you've made over this series of videos thus far! :))
Oooo! I definitely think a force sensor would add a lot of context to these videos going forward, as well as to past videos if he did go back and test them. He could honestly probably get away with just a normal analog force gauge by pointing it toward the camera, but he could probably also make some pretty cool graphs of force vs time if he's willing to invest ~$100 for a cheap digital force gauge on Amazon haha
I saw that he took the advice you (and others) provided relating to burning ABS indoors and moved outside for this video! Hopefully, he decides to implement this idea as well, for I believe that definitive force values for his tests could add a lot to the educational value of these videos (in addition to improving their entertainment value as well).
@@theplasmaguy3633 Oh yeah, that's true - I was thinking digital simply for ease of determining accurate measurements but I never considered plotting graphs of force vs time. It would be *really* cool to see the way the force output changes throughout the burn cycle. I noticed that most of the force in this video seemed to come near the end of the test, so that would be really cool to analyze in addition to its ability to overcome the friction inherent in his printer rail.
@@Tr3v1z3 I mean I'd argue that pointing a camera at a cheapo analog force gauge would probably be cheaper (or at least simpler), but yeah that's a great idea too!
I used to be a substitute teacher, and one school I worked had a tech skills teacher suddenly leave so I frequended his welding class. I wasn't certified with the state as a welder, so I couldn't let the kids work on their skills, so we'd talk. On day, one of the girls quoted their old teacher, and I pass his wize words to you now. "A grinder and paint makes me the welder I ain't."
Itengza is evolving from making rockets to making possible grenades. Also, why is the nozzle being held by the fuel? Only Nitegza makes a steel casing to have the part that takes the most pressure be held by the weakest part of the rocket.
If he asked for a 383 Stroker, Texas Speed would have it on his doorstep tomorrow...well, at least his search for Thrust would be over? But I wonder if Joe could get away with milling something on a home CNC?
I will never laugh unless you intended...love ya brother. Don't ever stop! You are amazing and will only progress!!! People like you are why our lives are better!!!
I've worked with a number of Portuguese-Canadians over the years, can't say a bad thing about them. Smart, funny, their culture fits nicely into Canadian culture.
Idea for a future video: You should definitely begin applying these rocket engines to some simple vehicles, such as a little rocket car, and maybe even further down the road an actual rocket
You should fully 3-D print a model rocket that actually flies! You might even be able to make the fuel by mixing a solid oxidizer with molten ABS or ABA plastic!
Dude you really need to wear safety glasses when using that grinder! That is literally one of the most dangerous tools you can ever use without safety goggles. Love the videos!
Future video: make a new sliding rail that is 4 ft long and point it vertical to see if the rockets can lifts themselves against gravity. *some additional ideas. Needs to be on some kind of bearings to reduce any friction and could even put it on a counter pulley system of the same weight as the mounting equipment so that you only see the affect of the rocket and its weight
@Danito FG lol well the inch is based on the metric system so it is a real unit :P. Ya something like that. We can make it 1.5 meters because that is a nicer number and that would be a little shy of 5ft i think. Oh its needs to be on some kind of bearings to reduce any friction and could even put it on a counter pulley system of the same weight as the mounting equipment so that you only see the affect of the rocket and its weight
@@feldamar2 Well yes, but actually no... If only SRBs existed you'd be right, but liquid fueled rockets keep their oxidizer separate from their fuel source. And also the walls of rockets are way too thin to contain the expanding gasses until it ruptures with incredible force like a bomb. The walls would break too soon for the gasses to go supersonic. meaning it's not an explosion being created and therefore, not a bomb. (Maybe an incendiary bomb like napalm if you count that)
Make a go cart sized plane with dual aero spike hybrid rocket engine with a pulse jet engine to facilitate take off. Add an aerodynamic body using carbon fiber and aluminum with the proper tools and instruments for flight but has to be self crafted and with sourced code for instruments. With goal of actual flight. This can be a video series.
I'm sure his neighbor re really delighted to have him. Him: "Honey, whats that hellish screaming coming from?" Her: "Oh, thats just our neighbor again...he build another rocket in his yard..."
Video Suggestion: While you may not have a metal 3D printer, you are able to cast metal for relatively cheap. 3D print an inverse ( mold ) of the nozzle you want to use in ceramic and then melt steel, pour it into the mold, clean it up after and try it out. Building a kiln is very easy and you already have most of what you need.

Hopefully, he decides to implement this idea as well, for I believe that definitive force values for his tests could add a lot to the educational value of these videos (in addition to improving their entertainment value as well).
The simpliest way is to buy a cheap electronic scale and use the strain gage inside of it and an arduino.
@@theplasmaguy3633 Oh yeah, that's true - I was thinking digital simply for ease of determining accurate measurements but I never considered plotting graphs of force vs time. It would be *really* cool to see the way the force output changes throughout the burn cycle. I noticed that most of the force in this video seemed to come near the end of the test, so that would be really cool to analyze in addition to its ability to overcome the friction inherent in his printer rail.
@@Tr3v1z3 I mean I'd argue that pointing a camera at a cheapo analog force gauge would probably be cheaper (or at least simpler), but yeah that's a great idea too!
In the breif shot I saw, your sheet metal looked galvanized.
I used to be a substitute teacher, and one school I worked had a tech skills teacher suddenly leave so I frequended his welding class. I wasn't certified with the state as a welder, so I couldn't let the kids work on their skills, so we'd talk. On day, one of the girls quoted their old teacher, and I pass his wize words to you now.
"A grinder and paint makes me the welder I ain't."
The old teacher was AVE wasn’t he?
"Trim, caulk, and paint make me the carpenter I ain't"
"Do your best, silicone the rest"
"You cant see it from my house"
Don’t let his animations distract you, he only moved because he was overwhelmed by the tomato forces
"Grinding and Paint makes me the Welder I Ain't!"
I used to love that saying until Doug started using it.
@@TechGorilla1987 why?
Theme for a video: use all the different jet engines to destroy a tomato, or launch it into space
Would be pretty awesome to see your take on recreating the very first liquid-fueled rocket that Robert Goddard made back in 1926
Itengza is evolving from making rockets to making possible grenades.
Also, why is the nozzle being held by the fuel? Only Nitegza makes a steel casing to have the part that takes the most pressure be held by the weakest part of the rocket.
At least that way, he won't blow himself up >:P
That way he knows that it will fail away from him.
Safety relief. If rocket go *BOOM,* weakest link is on the end away from Integza
Really, it's pretty brilliant.
3d print the falcon 9
Yeah thaht seams reasonable
You’ve been added to the list
A lot of it really is 3d printed!
Call relativity space.
Lifesize edition
The production value of these is insane, the animations alone bro
“Looks like a rocket to me” famous final words
"PSHHHHHH"
By far my favorite part about these is how disappointed Itegza always sounds whenever he is being consciously safe.
"I need a new way to make a nozzle"
How long before they start sending him a metal 3D printer
Or just a lathe and mill?
Get him an EOS M290
If he asked for a 383 Stroker, Texas Speed would have it on his doorstep tomorrow...well, at least his search for Thrust would be over?
But I wonder if Joe could get away with milling something on a home CNC?
I think at this point his country is going to just give him his own space program.
@@mgancarzjr the aerospike nozzle looked like it had some complex geometry inside, but milling it in multiple pieces might work
does anyone else find it kinda scary and kinda amazing what someone can make in their back yard
Integza:"Oh yeah I need gloves to weld"
His bare ass legs directly under the welding station: 👀👄👀
I noticed you only had one shot of him with the bear legs, and for the remainder he was standing. I think he figured that out the hard way.
That is unacceptable even by South African safety standards 😅
This channel continues to get simulaneously more entertaining and informative. Congrats on the new digs, Integza!
Good job for beginning. Welding pipe is hard. Don’t be afraid to keep that arc going.
we need a video with him and micheal reeves making some thing amazing,
and potentially blow up the world with their chaotic energy.
Add Nile red in there too to make it scientific😂
They both hate tomatoes too
Rocket powered machine learning tomato spike
integza doenst seem chaotic to me
@@xenomorphic8140 that's a great idea!
principally if he got some rfna and hydrazine!
Next Video Idea: Throw a Million Lions into the Sun with your Rockets and see who wins.
"Grinder and paint makes me the welder I ain't"
-AvE probably idk
Or this old tony?
Ave. Make a stein from a cat oil filter. Probably used for added kick
I love all of these proof of concept videos and great narration, thanks for the entertainment and information.
Neighbors: "Mom, what's that guy doing?"
Mom: "Making a rocket engine to hell apparently"
And it's like a demon screaming lmao
I will never laugh unless you intended...love ya brother. Don't ever stop! You are amazing and will only progress!!! People like you are why our lives are better!!!
you know what they say: "grinder and paint makes me the welder I ain't"
I like these INTEGZA VIDEOS. HES DOING THE KIND OF PROJECTS I’ve been saying for years, that’s what I want to do!
For a future project, INTEGZA , build a submersible rocket!
This was insane 😳 that supersonic flow was just lit 🔥
i see what you did there 🔥
Portugal is such a beautiful country , and Portuguese people are amazing, best time of my life was 20 weeks in the Azores
I've worked with a number of Portuguese-Canadians over the years, can't say a bad thing about them. Smart, funny, their culture fits nicely into Canadian culture.
The Azores are beautiful
Mate, im almost 100% sure integza is brazilian portugues and not european portugues
But your not wrong
@@dillonlamb2011 That would be interesting, always figured from the accent and scenery he was in Portugal not Brazil, I wouldn't really know though
Neighbor's wife: Honey, what's that screeching sound?
Neighbor: Ah s#it, Integza's rockets are going supersonic again
It isn't rocket
Lol
@@ImieNazwiskoOK then what is it? A pressure exhaust that gives propulsion?
@@potatocheeseballs5428 It's rocket engine.
It's like saying that jet engine is Beoing 747 or diesel engine is car.
You know what's good about tomatoes? Ketchup
Yeah its the only good thing about tomatoes
Dis comment is about to be bombarded by likes
Its a verified youtuber after all
that's because the only good tomatoes are dead ones.
What are you doing here autoaddiction? I love your content!
Lol what are you doing here lmao
Ketchup is the most pedestrian of condiments. . . Mustard is the far superior choice.
your sister's firefighter pose was very cute and relatable thank you
Idea for a future video:
You should definitely begin applying these rocket engines to some simple vehicles, such as a little rocket car, and maybe even further down the road an actual rocket
He just needs to build a longer vertical rail to keep things safe but still challenging.
Hypothesis: he wants to perfect his engines before putting them into a vehicle
@@secondlayer7898 or at least be able to get a positive twr vertically
"As you can see I'm in a different place. And the reason for this...I burned down my house"
You should fully 3-D print a model rocket that actually flies! You might even be able to make the fuel by mixing a solid oxidizer with molten ABS or ABA plastic!
Dude you really need to wear safety glasses when using that grinder! That is literally one of the most dangerous tools you can ever use without safety goggles. Love the videos!
Future video: make a new sliding rail that is 4 ft long and point it vertical to see if the rockets can lifts themselves against gravity.
*some additional ideas.
Needs to be on some kind of bearings to reduce any friction and could even put it on a counter pulley system of the same weight as the mounting equipment so that you only see the affect of the rocket and its weight
@Danito FG lol well the inch is based on the metric system so it is a real unit :P. Ya something like that. We can make it 1.5 meters because that is a nicer number and that would be a little shy of 5ft i think. Oh its needs to be on some kind of bearings to reduce any friction and could even put it on a counter pulley system of the same weight as the mounting equipment so that you only see the affect of the rocket and its weight
Wait, Tethon 3D gifted you a 20.000 $ Printer? 👀 - Nice! Happy thicc printing! 🚀
Yeah that crazy, when i looked it up i was amazed. 17500 euros is so much for a printer and he was gifted one. Or mayby they lended it to him.
We gave him Bob because Bison hate tomatoes.
7:25 when you realize he's making a pipe bomb with a nozzle
Congratulations. You just discovered why Rocket Science is hard. That is EVERY rocket ever built. How to make a pipebomb that DOESN'T explode?
@@feldamar2 Well yes, but actually no... If only SRBs existed you'd be right, but liquid fueled rockets keep their oxidizer separate from their fuel source. And also the walls of rockets are way too thin to contain the expanding gasses until it ruptures with incredible force like a bomb. The walls would break too soon for the gasses to go supersonic. meaning it's not an explosion being created and therefore, not a bomb. (Maybe an incendiary bomb like napalm if you count that)
‘The gloves.... I forgot to wear gloves!”
Sais the man in shorts 😂
Dont forget the flamable thin summer clothes.
It is a relief to find someone who speaks Englisch in their videos but doesn't use inches/feet
Cring

„A grinder and paint makes the welder I ain’t“ AVE
Skookum remark!
Did he use any protect gas at all
I was going to make that comment, but found that another citizen from the empire of dirt was here.
The problem is that he isn't using a shielding gas. Once he figures it out, I think he will be surprised to see that he is able to weld.
I'd have used gas-pipes. You can saw it to length, then you can put threads on it and you can screw on all kinds of caps, adaptors or flunches on it.
Building a rocket test stand, where you can actually measure the thrust of the engines, (if they don’t explode :D) would be awesome.
all he'd have to do is attach the rocket body to a load cell
Having a temperature sensor (camera) would be good too
Mount the rocket to a kitchen scale to measure the thrust?
Bonus points to see how high the nozzle goes when it ejects... vertically.
While you’re at it, it would also be funny to calculate the specific impulse of that little rocket, if your high speed camera can pull that one off
Video quality and production cost is getting better and better ❤️❤️
Can we just get this man a metal cnc mill already. It's impressive for being made of plastic
How about a metal sintering 3D printer? That would be more his style, and the prices are creeping slowly downward
@@chillaxter13 They are still pretty expensive and the powder is very very costly and has a low shelf live
Make a go cart sized plane with
dual aero spike hybrid rocket engine with a pulse jet engine to facilitate take off. Add an aerodynamic body using carbon fiber and aluminum with the proper tools and instruments for flight but has to be self crafted and with sourced code for instruments. With goal of actual flight. This can be a video series.
As soon as he made it out of metal it started to look great and starts working better
Or may be its because of the oxygen supply increasing camper pressure
I'm sure his neighbor re really delighted to have him.
Him: "Honey, whats that hellish screaming coming from?"
Her: "Oh, thats just our neighbor again...he build another rocket in his yard..."
F for neighbors...
15:13 Me when I step on a Lego piece
yes
My room has so many legos that when i step on one, ive done it so many times that it doesnt hurt anymore
that made me laugh!
LMAO
Haha, loving the lack of flashback suppression between rocket and tank.
Video Suggestion: While you may not have a metal 3D printer, you are able to cast metal for relatively cheap. 3D print an inverse ( mold ) of the nozzle you want to use in ceramic and then melt steel, pour it into the mold, clean it up after and try it out. Building a kiln is very easy and you already have most of what you need.
Yes loss PLA casting!
melting steel isnt a walk in the prk
@@samuelyoung2671 are you playing the tomato my friend? Lol a crucible is cheap enough, make a paint can forge or an induction forge for an even easier way. It is just heat.
@@JSabh U ever tried to cast steel? If youv've had success im impressed.
