Building and testing the most dangerous and outrageous grinder disc designs! In today's episode we have Quad Amputator 5 000 000! It has 4 really sharp saw blades ready to spin 10 000 rpm and spread love around! Don't try this stuff at home, all designs here are designed to be entertaining content, not to be used in real life by anyone. Manufacturing any of these designs is going to result in terrible injuries and death! We are trained professionals with strict safety plans that allow us to test these safely in controlled environment with out putting anybody on harms way.
I am so hyped up about this video series :D Please keep the suggestions coming for disc designs!
chainsaw chain welded to the disc like flails?
For the next one I'd love see chains attached around the perimeter of the disk, maybe from a chainsaw?
Maybe a flaming disk! The fire will help it cut better probably
You are my favorite channel on KZhead! Thank you for everything that you do!!!
I'm interested in how well it would drill. Like if you mounted various sized drill bits to the center, turned it facing downwards, and used it like a drill press.
My first summer job was working in a plastics factory when I was 16, they gave us grinders with saw blades fitted to chop up the waste plastic for recycling back into the moulds. Fun? Yes. Effective? Yes. Dangerous? 25 years later I still have a scar on my arm!
By the sound of things I'm surprised you still have an arm
@@scotty1004 He was taking about the scar on the arm that he was left with. ;-)
Not sure what country your from, or what state if you live in the US. I do know in most US states 17 or 18 is the age limit to use those type equipment, under that age breaks child labor laws! There is exceptions for kids that live on family farms and I think certain family owned businesses have exceptions.
Haha, similar here, we use them carbide tipped blades on handheld grinders to cut aluminium radiators :D
My first summer job (16) was cutting firewood using a PTO driven circular saw. I was told if anything happens to call the boss on my phone and was left to work alone. Later I chatted with another member of staff who told me the last fellow who worked there lost a finger on the saw.
If you’ve never used an air filter these are great. kzhead.infoUgkx_dppjvjF8BYEmPSDTcgCUdRsgWYLXNHN I ended up with three after starting out with one. The noise level depends on the 1-3 settings with how hard you want the machine to work. You can also upgrade the filters and get one better for pet hair and smells which is a must have in my home. I noticed the air seemed lighter and easier to breathe when running the machine for the first time. Works great every time. Highly recommended!
You guys should connect the grinder through a variac so you have good control over the input power
At the very least, I'd use an extension cable with an on/off switch over plugging the tool in and out of the socket.
Those cheap switches will immediately weld the contacts due to high starting current and are way worse than current way.
Even just a cheap router/grinder motor speed controller would probably do the job
Had the same thought
Or at the very least a power supply with an on/off switch
That 2nd thing looks like something out of what you could pick up in Doom.
She doesn't look undead
@@thebarkingmouse 🤣
@@thebarkingmouse Ooo no you didn't! I laughed, so I guess I'm going to Phobos, via Hell.
The Monster chopper 3000! Cuts everything in half nice and Clean!
for me it looks like some weapon from Painkiller
I can't believe the grinder actually spun that thing without completely destroying itself!
It's also crazy how little there is vibration from these. they aren't balanced in any way :D
@@Beyondthepress I need a grinder like that! What kind is it?
@@jamesa7506 I don't remember but I will tell on the next video. But these were super cheap and they have speed controller also.
Looks like the cheapo Brücke 900W/125mm
@@Beyondthepress did anni get new hair color or did you get new wife?!
Beyond the Press is great. I know Hydraulic Press channel is bigger, but this channel is way more fun.
Perhaps HPC pays the bills, BTP creates the bills 😂
@@ashriihi Exactly like that, I remember Lauri explaining that, probably in the much missed twitch streams.
You guys should do the four blade version with a planetary gear so they all spin!
Exactly what I thought as well!
That was my first thought too. Sick minds think alike, eh? 😆
remind me some mecanics classes 4years ago :)
how would you make that centre gear not move?
Ya. Why wouldn’t you.
I love all the "try not to die", "probably not going to die" and other similar descriptions... It makes it abundantly clear that these things are 100% totally safe😁 Some video game franchise definitely needs to license these designs...
Now that's indeed one thing I will never try at home. I normally think those warnings are ridiculous, but this was truly dangerous, haha
That's why you don't try this at home. That is what neighbor's homes are for.
Hanna has the right kind of imagination for this channel.
When the grinder started to rotate the piston, I got a lump in my stomach that five minutes after the fact hasn't gone away yet. This is by far the biggest physical reaction that KZhead has ever given me - I wouldn't even want to be in the same post code as that monstrosity! Well done!
"Start it and try not to die" Glad to see you two are still up to the usual madness. :)
Him explaining that in the beginning was super funny, like yeah you're definitely going to hit messed up or dead lol
The quad blade laid horizontal looks like one insane killer drone. Love it!
I think that would be also really cool design :D If you would actually be able to make it fly :D
Make ”a killer drone”. If it could fly it could have some practically-points..definitely it would have 5/5 kill-points. But you need a bunker or mbt for protection. "Things that should not exist".
@@mielikuvitelma could maybe do it with a propeller with an outer ring on it, but attached to the outside of that ring is some kind of blade around the edge. Test it by trying to prune leaves and tiny branches on a tree. Effective? Probably not. Dangerous? Extremely.
Great, you've given them another dangerous idea. 😆
@@Beyondthepress Four blade drone for trimming trees. This sounds right up your alley. The Tree Trimming Drone of Death
I use a grinder every working day... this series is both terrifying and darkly fascinating. Thanks for doing it safely that I can se it.
I was not expecting the blades to work like that. in fact I expected much worse. I am both shocked and relieved it worked out as well as it did. definitely looking forward to seeing what other horribly dangerous ideas you two cook up in the the next video.
And don't forget "really stupid".
It would be a pain in the neck to get anything resembling balance out of it, but hammers would be neat to try! Maybe ballpeen hammers or those small carpenter's hammers (these could also be tested both ways [the hitting part vs the fork part])
Seems that this is not super critical about being balanced so hammers are definitely coming!
If they were hinged they might each get a decent hit rather than just skimming the edge if welded solidly, a bit like a flappy disc sander thingy
@@Beyondthepress In that case, definitely go for the carpenter's hammers! Combined with @Commiellama s suggestion, make them hinged and test both ways!
Axes could be fun too! That increases the terror factor to 11 though - don't try this at home, boys & girls!
@@Beyondthepress did anni get new hair color or did you get new wife?!
Yeah that's a terrifying creation haha. Nice work. I do like the changes in filming style. This was a fun one.
This is probably my favorite video series you’ve ever done!
That laugh from Hanna when the first wood shot sideways was awesome Love this series
Who is Hanna, how do you know her?
@@mikpiece469 There is a pinned comment about that topic in our previous video
@@Beyondthepress - thank you / I didn't know you had a commentary there... To you Hanna welcome
@@Beyondthepress bro your life is your business, shit happens and you have to move on. But some things are a tad weird. One of the quirky things about your early channel was Annies unscripted laughs and shreiks which later became a staple of your videos. Eventually, it would be really weird if you didn't hear them. Don't try to recreate that effect with Hannah, let her make her own thing, it would be just weird if someone else took that role. And please please please, don't get her to do extra content play-dough animals! 😂 Wishing you all the best and I'm excited to see what unique attributes Hannah brings to the show!
@@spackerinternational6131 dude, they are just having fun and it's her natural reaction. You are the only one being weird.
- Rubber tire! Something that is rated close to the maximum speed of the grinder so you can spin it full speed. - Biggest bearing you can find. Attach the inner race to the grinder and see how will the outer race accelerate when you turn it on. Then push the bearing against something so only the inner race rotates, experiment how much load can it take with or without oil.
bearing is great idea! Maybe even multiple!
I totally get this fear of one's own invention. About 15 years ago, I was tired of breaking weed wacker line, so I replaced the plastic line with the strongest steel line I could get as a science experiment... and it was terrifying to be anywhere near it and the shards of wire coming off it when it was slicing through, well, basically everything. Do not try at home.
I love the chaos of this series, keep it up!
With the 4-blade setup, I was surprised to see that the individual blades were not counter rotating on their individual axis when coming in contact with the wood. In the slowmo, it looks like they are mounted solid.
i wonder if that would keep it from catching and kicking back
I love this series! I think a chainsaw blade flail would be amazingly dangerous. Also something less likely to work like 4 high pressure hydraulic hoses attached to the centre ring.
Great idea Hanna. I declare you are now an official Woodworker. 😁
The reaction shots of you both is great, good work, very entertaining. I like how you call out the safety items you considered.
As many insane things as you have done and built over the years this is just truly over the top!
More crazy ideas from Hanna, please!
“This is the end of the sensible part of the video”, most of your vids should start with that. 😂
Just when I thought the press channel couldn’t get any better you start this channel. Absolutely you two are mad and I love it.
Plus points on safety, taping the plug is really nice touch.
Hanna gives a good vibe to the video's!!
Try mounting 4 like a dado blade you will have to extend the screw that holds the blades in place but that might be fun with all the different configurations you could come up with based on the spacing
I really appreciate that dedication to safety, even taping the power cord.
entertaining and crazy at the same time. this one is insane. whenever i feel the need for some chuckles beyond the press is my new go to. greetings to you & the missus from michigan's upper peninsula. you guys crack me up!
Now you need to try setting up the 4 blades like a planetary gearbox! Or maybe grinder discs on there?
Suggestions: -angled grinder: -The blade is mounted in way so that the blade i parallel with your arm. -solar grinder: -its like what you build, but the blades are powered by gears. The grinder shaft resembles the sun, the mounting hole for the blades are the earth and the blades are the moon.
I am sooooo happy to see new videos on this channel! please keep it up :D
YEEEEEEEEEESSSSSS!!! Heavy Metal music, fabrication video of completely madness attachements. This is the best HPC/BTP in years and that says a lot!
The second ’tool’ reminds me of the giga disc projectile orbit from Noita. You and the game devs are both Finnish, so I guess sawblade orbits run in the blood. Next time I recommend making the orbiting saws spin too to increase risk to the user.
YOU HAVE ANGERED THE GODS
Planetary gears!
I have seen some pictures of people mounting SK40 tool holder to angle grinders (with the pull stud thread I believe). Yet I have never seen a video of someone trying to use an endmill in an angle grinder
Haha, this was great. Great idea Hanna! The MadGirl.
This is one of the most terrifying things I've ever seen. Well done!
Anni can't be replaced.... the vibe & content is not the same.... it's been a good run. God Speed Lauri.
What happened to Anni?
@@jacobolson6885 In a comment left by the channel on a previous video they said they had divorced but remain friends and Anni didn't feel like being a part of the KZhead stuff anymore.
At first I though, “Anni looks so different with blonde hair.” Haha, and my brain kept trying to process it until you mentioned a different name and it made more sense haha. Love this series!
I’m just glad you’re back to the stupid/dangerous videos and less of the boring testing videos haha. Welcome to the team Hanna.
Where is anni anyway, haven't seen her I a while?
@@Catlover1375 divorced
@@Catlover1375 She is working on her own projects as far as I remember.
@@Catlover1375 I was wondering the same thing
Your idea engineer is on a new level, keep up the good work Anna😊
Great Googily Moogliy... I was terrified for you LOL
When you said 4 blade grinder, I thought for sure it would have gearing to make the 4 blades spin individually in addition to the overall thing spinning
I thought similarly - that the frame would be stationary and the spindle would drive a gear, but putting a stationary gear on the body of the grinder that spun the blades on the already-spinning frame would be so much more dangerous!
Right I was expecting a planetary gear kind of setup. Ended up being more of a spinning axe than a saw. Didn't kick as hard as I expected though.
@@stove5035 I was thinking 2 large rubber bands on pulley wheels behind each cutting disc. In an X.
@@lokicam1307 Probably would be even better if you used bicycle chain and a few sprockets.
lawnmower blades could be fun, bonus they already have holes in them for mounting =)
Lauri and Hanna y'all rock! Love the channel and content! Peace
Great idea for a metal band name. Bone smoke. Thanks Lauri and Hanna!
How has anyone survived a finnish woman?
Hi Lauri - great series. There might be a smaller electrocution danger you haven't considered. When any grinder disc continues to spin under its own momentum, there's so much inertia, there's a possibility the motor may act in reverse as a generator/dynamo when unplugged, and that the exposed conductors at the plug could give one of you a significant electric shock if both are touched (or via earth, even if only the live one is touched). It's simple to make your setup a lot safer, by adding a switch into your circuit.
I think power draw, or switching.’c is needed for a reluctance motor to generate. That may not be true.
Yes, residual magnetism may be left in the motor which will allow it to produce some current. Example: kzhead.info/sun/lbOLgLeiiHOsmXk/bejne.html
You guys always have the best ideas!
There is no way you can invent an attachment more terrifying than the quad-saw. I'm calling it now the season winner!
The 4 bladed one would be more interesting if you added a sprocket and bearing to each, and a nut on the shaft that could hold a chain statically. That way when it starts up, the statically chain forces the blades to spin individually as well as all 4 spinning on the mount.
With something as dangerous as that grinder, ideally you'd need to rig up a press control that allowed you to control it from outside the workshop (so well out of harm's, way if it did start flying!), relying on a live camera feed to show what was going on. Probably with cheap cameras near to the press and any expensive cameras far back with a long lens attached.
I am armoring my front loader with inch of polycarbonate. So then I can operate these and be totally safe. Just being outside isn't much since normal walls aren't that tough against flying stuff. 12mm of polycarbonate that we have on the box and our shield are already probably both tougher than our workshop wall.
@@Beyondthepress did anni get new hair color or did you get new wife?!
Gawd I love this channel! 👍👍😊
"This idea doesn't make sense, excellent idea let's do it " is a good motto to live by if you like fun
"Alright that's enough, this is truly terrifying and we were scared and didn't want to get hurt, stay tuned for the next time when when put something worse on" lol. I love it, these were awesome videos, I wouldn't dare even hold the first one and turn it on, you're definitely getting messed up bad lol
You should add a geardrive mechanism so that the 4 blades are powered too
I would love to see some steel wires welded in to a wheel and see how well they do
aka, angry wipper snipper
Less of a weed wacker, more of a weed lacerator.
The expression on the squash’s face is brilliant! 🤣
You guys are such an awesome pair of humans, glad you met and made this : )
Also maybe testing different kinds of glass as cutting disks, idk if any will not instantly explode but even still thats fun to watch.
I need a parts list with dimensions. 10 out of 10 need this in my shop!!!!
This looks so stupid that I have to hang this to workshop's so definitely conversation piece :D
Yes! Beyond the press is back with the cool stuff!
Best series ever 👍👍👍
Your new assistant is great..keep up the fun idea's..
It isn't completely useless. You used it very well to entertain over 100k people so far
Make a disc using surgical scalpel blades.
6:38 INTRODUCING .... The murder saw!!! 🤣
omg the scream scared the crap out of me 😂
I felt like i was in danger by just clicking on the video.
Okay, that four saw blade grinder was the most dangerous thing you guys have ever made on this channel...and I love it! (Edit) As soon as my sister saw this, she said that you should have an accessory bar that extends to four MORE saw blades
Fractals for the win!
Even though I know nothing can hit me through youtube, I still winced every time those damn things spun up. Great idea for a series, I can't wait to get even more anxiety in the next videos!
This series is so good I’d turn the first one on in my hand
Where's Anni hope she's well.
Read explanation in pinned comment on a previous video. Anni and Lauri have divorced and she will not be anymore on these videos.
She's doing great ❤️
You should use a variac to control the speed :)
I will get one for truly stupid designs :D
@@Beyondthepress What was this design if there is something even more stupid?
@@hhdhpublic I don't know, swords?
@@Beyondthepress How about blunt objects? Such as hammerheads, unsharpened steel bits or such?
@@Beyondthepress lawn mower blades? Heheh
That was a great video. The death grinder. I can't wait for your next video. Your videos are always Bad Ass!!
The reaction camera shot was a long needed addition. Awesome!
How about attaching a couple of axe heads? You could weld a couple to a disk like last episode.
This is coming! I have to just armor up my front loader before truly stupid designs :D
@@Beyondthepress Time to use something safer then. How about potato peelers? >:P
with anni pursuing other things does that mean there will no longer be dangerous clay creatures to deal with?
Do you know what other things she is pursuing? At first I was concerned they may have split up since I’ve not seen her in a while
@@perryFBA They did split up. There is a video on Lauris channel (in Finnish but with subtitles) explaining the situation. TLDW: They got divorced on good terms. Lauri will keep doing HPC and BTP and Anni is studying Visual Arts and isn't sure where she will go yet.
@@perryFBA they did split up and divorced amicably, the last video explains and there is a subtitled video on lauri's channel . i wish the best to everyone.
Hahahhaha I think Hanna scared you more than the grinder grabbing the block and flinging it🤣🤣🤣
How can we make a blade more dangerous...? Hannah: add more blades! I like how she thinks!
If it's dangerous, don't try it at home. Try it at someone else's home.
There’s always a loophole
It's too dangerous to try it, period! :-D
Magnificent madness!
I pulled my hand away from the computer by instinct when you turned the first saw blade on. These are some truly unholy terrors you have braught into existance.
The slow-mo faces are priceless 😂😂😂
My creepiest angle grinder tool is about 0.6 kg disc with three adjustable blades. . It is commercial product for wooden log construction, I can strip bark and smooth the log surface. I have soft start in grinder and can feel the inertia when turning it during operation. Keep going, waiting S1E3 already!
yall are so fun. thank you
Great idea Anna!
We need more of the the crazy dangerous videos like this awesome video
Your safety glass discipline is admirable.
Damn! This is one hell of a channel!
You guys are friggin awesome.
I had to sub for more of this madness!!
1:20 "If you're actually trying to do something, you'll definitely die during the first work day. I give it 3/5." Brilliant stuff and I love this scale!
You might want to look into clearing saw/brush saw blades. There's some really interesting ones meant for grass, shrubs, and small trees
Engineer. A person that finds a solution to a problem you didn't know you even had in the first place.
The brutal honesty at the start "if you do your best to not die, you probably survive. but if you try using it, you die. so 3/5". The best comedy is honest comedy.
