Best Weapon to FIGHT ZOMBIES 

Thanks Techland for sponsoring this video! Dying Light 2 Stay Human celebrates its 1st anniversary with a 50% OFF sale! Check it out here bit.ly/IntegzaDL2 #ad

If I saw such a well dressed man in an apocalypse I would be terrified regardless of the weapon

Congrats on achieving the worlds first semi-practical chainsword! Its a long way off from being battle-ready, with all the exposed wiring, bare metal shaft and the chain ready to fly off in your face at any moment, but its one hell of a lot further than other attempts i've seen.... *looking at you, Man At Arms* I realize you probably scrap this and re-use the components fairly quickly, but i'd love to see a Mark 2 version of this sometime.

Nice chain-sword Mk.1, next step in a future video should be making it in the style you and many of us envisioned it; 40K-style! It should be possible to slide a smaller electrical engine into the pole for direct drive and with a slightly smaller engine the weight of the battery and motor might make it almost one-handed depending on the effect and running time you expect.

The "Safety Third" was fantastic at the end. I loved this vid, stay great Integza!

This has been the best chainsword build I have seen on RU-vid. It actually works. The only downside is it doesn't make the sound, but who cares when it takes heads off with ease and cuts a skull open like it was a loaf of bread?

imagine how ancient sword experts would react to a monstrosity like this

I like the fact that he basically showed a Warhammer chainsword at the start, and picked it apart then made a weapon that would make Constantine Valdor proud

Topic Suggestion: try to use a pulse jet engine to create a rotating detonation wave inside of your turbine engine’s combustion chamber Thoughts: use regular turbine to initiate airflow, once proper airflow is reached, turn off (turbine fuel) and use pulse jet to induce the rotating detonation wave. It might work. Thoughts?

Integza is a really bright guy and still decided to go face the apocalypse wearing white pants. He's unstoppable. Edit: Tomatoes are disgusting!

The tiny chainsaw on my polesaw scares the absolute hell out of me, this thing is one of the scariest things I have ever seen you make Integza. Please be careful, I like watching your videos.

That was unexpectedly awesome. Never saw someone cutting a head in half vertically with a chainsaw being so wholesome!

Hum... I honestly didn't expect it to work THAT well. These kind of chainswords tend to get stuck and break, however you did give it a lot more of a swing than other content creators and it still worked. Plus, you managed to make it all into a pretty compact design, more reminiscent of a pole arm than a sword to me, which is great. I know it's a hell to build these monsters, but I'd really love to see some abusive testing, maybe on some tougher version.

Chainswords look like fun. Also, it would be epic to see you on the safety third podcast!!!

I think it's been discussed before, but the most ideal form of offensive chainsaw would be a chainsaw spear. Long pole to put the chainsaw bits far away and allow the user to adjust their grip to change the weight distribution as needed

This is the best engineered chainsword I've seen, you are amazing. To make this perfect I would: Cover half the chain to make the sword single edge, it makes it safer and would help to keep the chain from jumping of the sword. Align the batteries length wise, it brings the centre of gravity up closer to the centre of the weapon. Reinforce the pole and make it longer, 75 cm motor and battery, 75 cm handle, 100cm edge. It would be more of a spear/polearm but it would be the perfect weapon: A bit longer and heavier but easier to use and less likely to break.

I am horrified by your lack of safety procedures when testing this thing. That said....REALLY freaking cool project, and highly effective! Well done!

Really cool idea for the apocalypse. I noticed that while you were running it, the chain was throwing sparks. Be nice to see a bar lube tank be installed on it so the chain doesn't lock up. Also, adding something to tell you how much battery life you have left.

Just keep making the videos Joel. That has got to be the best idea yet. On a more serious note since you vid about momentum up till this one we can see how much you have progressed. I am a retired engineer and can appreciate the work you do to design and execute your work. As I said, keep going.

This, along with Integza himself honestly, look like something youd encounter 5/7ths the way through a game when you have to go through that "advanced" area

Chainsaws are terrifying as it is, this is beyond scary

"It's like a Chihuahua! It's small, but it makes so much NOISE!" - Integza, 2023 12:33 Integza is a lean, pristine, mean, Zombie killing MACHINE!

Honestly this was crazy af, you're insane, but also super brilliant LOL. Keep up the awesome content!!

Hey Integza! Great video as always! Your chainsword looks sick and definitely the best one I've seen on youtube so far. As a fellow man of science, I just wanted to point out a couple details though that may help make it a little better! #1.) I noticed that your chain was throwing sparks earlier in the video, for this you'd want to attach a bar oil tank at the base of the chainsaw blade, it'll keep things smooth and prevent chain lockup. #2.) Your chain was on backwards! While it'll still cut "fleshy" things with ease, eventually in the midst of a zombie apocalypse it'll end up dulling the chain super quick with all that bone. A good way to remember how it goes on is that the little triangles on the chain (not the blades themselves) need to be facing out towards the end of the bar, so the rounded edge is pointing towards what you want to cut

The nitro engine uses spring clutches . You need to pull the throttle to move the clutch bell (the gear on the front)

you're running it upside down or backwards. the lower part of the blade should have the chain drag the machine away from you, not towards you, this is a safety thing so that if the blade snatches on anything the blade shouldn't jump towards you. nice item, stay relatively safe.

This was the coolest thing I've seen all day, the vertical cut on the ballistic dummy was LOVELY 👁👄👁

14:55 "Thats so gory!!!!" *Proceeds to rip the skull open with his bare hands*

So we are headed towards the 40K future then? And Integza is the inventor of the first prototype chain swords? I didn't know I was living in the golden age/dark age of technology.

Was anyone else terrified of kickback because the blade was rotating opposite of a normal chainsaw?

9:45 safty on point

Suggestion: an old-school hockey (safety) mask would make a brilliant addition to your fancy appearance!

This man is literally ready for anything, just team up with the rest of the science tubers and you can take over the world

Video idea: make a rocket engine using household items. For a fuel you could use a hydroxide generator which is pretty easy to make.

Awesome idea and build! Keeping with the zombie killing theme, an idea I had was for a pole weapon (can't let them zombies get close), that when the tip is stabbed into a zombie (head or body) would trigger the injection of a compressed gas into the area of the body. Which could, in theory act like over filling a balloon, resulting the explosion of the body area. Or at least in an enclosed are like the skull, everything inside would be well blended.

Wat is about an rocken thats starts from water and goes in the air with an jet engin ?

Integza is singlehandedly bringing us closer and closer to 40K

You should make this into a series creating Zombie Apocalypse survival gadgets!! 😂

These guys are absolutely awesome! 💯

I love this channel. Integza is fantastic entertainment

That's pretty awesome! Though one thing you might consider in the way of upgrades is some kind of squeeze trigger rather than a knob, that way you don't have to manually adjust the knob to turn it on and if you drop it it will turn itself off rather than having to try to wrangle an uncontrolled chainsaw.

ITS TIME INTEGZA we need a video series on your quest to becoming an accomplished welder

With the topic of video games and the recent release of the dead space remake, it would be cool to see some of the weapons from the series brought to life. You videos are always full of wonder and awe. You are a great creator and your creativity has no bounds.

Dude youre insane love your clips! Keep it up!

Video idea: continuing in the theme of making cutting objects but also keeping kinda in the theme of your normal videos: make a water jet cutter. You can test different nozzels with 3D printing and buy something like a hand with this ballistic gel to test it (and also tomatos, of course)

Make a thruster which will run on hydrogen and oxygen generated from hydrolysis of water.👍

You've done so many things already. I think a diy RC jet boat would really tie many of your skills together and make for a great video series!

Make a Jet powered RC boat with a exotic Jet. I love how inspirational your videos are .

I think in future video you should build something powered by this little 2 stroke engine. And maybe somehow upgrade it? Or make a hybrid vehicle that uses this engine, a DC motor and and somehow regenerates power? We all know you can do it man, and remember Tomatoes are disgusting.

Out of every single video this guy created this has to be the most metal literally sawing through a accurate re-creation of a human skull with a chainsaw sword with chunks of the accurate re-creation of the brain and blood flying everywhere

I would love to see you collab with I Did a Thing. This video had big IDAT vibes. You'd create the BEST apocalyptic contraptions! Also I had to add... "Now let's see Paul Allen's card"

This is awesome! You're a true genius, I came for the printer long ago, but I stayed bcs of your ingenuity! Next time I would love to see one of your rocket engines fly, preferably with some control of the flight!

Probably the best video on this channel thus far. Cool! Nice that Techland agreed to sponsor it.

I've discovered that pine logs make the ideal hybrid rocket fuel. I'd like to see you experiment with that, it's quite amazing really.

LOL congrats for the surprise with the bl00d, must have been tons of fun 😀

Integza with "blood" on those clothes kinda gives that casual zombie hunter vibe, and I like it.

"theme for a future video" : you should try to do a 3d printed car or something you can move with 😅

One of the better, thought-out zombie killers. Well done integza! When you made the vertical cut and the after reaction! You really got that chain moving! Decent size battery pack, you could take out a lot of zombies!

I juat love how stylish he looks while doing all of his experiments

i think you should put some sort of safety trigger so that if you remove your hands from the handle you can immediately stop the chainsword.

Video Idea: I would love to see you come up with your own design for an engine. I think you have learned a lot from recreating different unique engines but if you were to build one completely from scratch yourself how would you do it?

something to note, im fairly certain that chain was self distructing at 10:10 and also you had the chain on backwards and the saw running the wrong way so, it was still cutting like a mf but the top side is the one coming back towards you, typically it would be the botom which comes back towards you

Good thing this was 14:52 sponsored

that worked so much better than i expected, that motor is nuts

Hello, Build a thrust vector control system and test it with your prototypes!

Integza becoming the the real "CHAINSAWMAN"!!!

I half expected Integza's zombie apocalypse plan to be: "Escape the earth in a 3d printed rocket."

You should try to make another game/film themed video, like trying to recreate or show us your own take on some wacky weapons or contraptions (like something from a spy movie oriented like a lunchbox that shoots rockets when opened or maybe some strange gun from deep rock galactic, Warhammer 40k etc.)

You had me very nervous with the fingers and the cutting.... Your a mad scientist! Love it!

it's so amazing seeing you go from a few hundreds of views per video to getting a big sponsor, Good Luck man!

Damn I’m glad you showed up in my feed!!! Good shit man!!

Your channel is so good dude. Well done.

I LOVE your rocket engine videos and honestly sighed when I saw the title of this, but dang am I glad I watched it! Easily one of your most fun videos. You should continue this series. Maybe some sort of nail gun attachment for your wrist with a laser sight for easy headshots!

Dying Light and Integza, two of my favorite things united!

14:51 The way you open the scull got me rolling. Like in a game like mortal combat…just pure violence and cruelty but it luckily was just a prop.

I love the blade music!

I’d love to see a 3d machine that can make another machine. Like a whole machine! Could be anything really but that concept keeps me awake with energy sometimes 🤙

Chainsaws were originally invented to cut through bone during autopsies and childbirth so it makes a large amount of sense for it to be used as a zombie slaying weapon!

i love the fact that he wears a simply and nice clothing but uses a destructive weapon......gets another sub!

Great work! I think a great project would be to get some hot wheels cars and add different kinds of motors to them and send them down the track! Loops and everything! Of course I suggest rockets but it would be fun to see your different ideas. Supersonic hot wheels!! Maybe make your own track...

Next video - a rocket swing, for tomatoes perhaps 🍅😡 Awesome video integza, production quality and ideas were on point, and I really enjoyed the whole thing. That destruction montage has got to be one of the best, and it looked so much fun.

Thank you, for your always entertaining videos. I suggest you could try to make polyvinyl nitrate (PVN), should work similar to the nitrocelullose, but is a thermoplast. Meaning you could print it in a classic FDM printer, when you make a filament of it.

for the weight it be dope to make like a wrist mounted chainsaw that mounts along your arm for weight distribution and like a hidden blade type of vibe

What an amazing and entertaining video! How about making a portable co2/ high power laser cutter? Cheers!

Video Idea: A rocketfuel propelled sword/axe so things can be cut with superhuman strength/speed

Awesome video as always! I'd really love to see you on the safety 3rd podcast.

Integza should use his jet engine and rocket knowledge to build a model space shuttle! Could be fun to see aerodynamics come into the equation

@integza I hope you noticed all the sparks coming out of the housing. Feels like either the pinion or chain will break in time. at those speeds that something you do NOT want to happen.

Video idea: build a 3d printer with a 3d printer and build yourself the metal parts. 👍😎

saw you had your chain on backwards in the first iteration, then realized in the final product you had your chainsaw spinning backwards too, so it worked out in the end!

Video idea for March... It's international women's day on the 8th of March. I assume, since you're into rockets, that you're also into planes. Build a kind of 1920's reconnaissance style plane (like a Caudron G3) to honor Milú Sá Teixeira (the first female pilot in Portugal to get a license). You could make it electric or use that RC engine you didn't get to use for this project? Tom Stanton may be able to assist as well!

Idea of a theme for a future video: Put a tomato inside a jet engine. You could probaly do this by 3D printing a jet engine with a little section for the tomato or something.

Awesome Power-Chainsaw XD I see it coming: One day, Integza is going to get one of these markforge printers and does a space marine style chainsword printed in metal. A propos safety third: an improvement for this one would definitely be a safety grip that, when letting go of it, stops the chainsaw. Plus some protective sheet on the back of the sword that keeps the chain from flying towards the user when the chain breaks.😁

Integza gives us the the perfect balance of destruction and comedy. 💪

Since the chainsaw isn't used for heavy cuts through wood you're probably fine without an automatic oiler but it's definitely a good idea to manually oil it before each use. (You can see sparks coming off it just free spinning)

You should add the combustion stage if you want thrust. This type of fan is basically a compressor that creates high pressure air not necessarily high volume which I think is likely the issue you are seeing. I would also suggest looking into turbocharger geometry and giving that a try. Finally you might not be getting enough RPMs to get the results you want. A turbocharger can spin at speeds over 100,000 RPM so you might need a gearbox or something to increase the rpm to a sufficient speed.

You should make a liquid nitrogen + boiling water propelled rocket engine or kind of reaction control system / RCS kind of like in this video! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1a1iHUd_14Q.html

Now with 100% more blood than expected!

Integza this video has gotten my vote for "Most Bad Ass Build of the Year". Do not dispair, the Zombies are still coming! P.S. Make sure you add the motor pulley guard so you don't get anything important caught in the drive belt.

My favorite video from you to date!!!
