hello angus! i live in ukraine, and, as all things from russia, these locks are quite commonly used - however, only in heavy-duty or simply heavy-abuse applications. There is a lock like that "protecting" the 3d printing farm over at my job, and whilst it is not a perfect secutity mechanism, it does its job well enough. The main feature of it, that makes it carrot-, picker- and pecker-proof, is a springloaded gear that needs to be turned with a lock simultaneously with the main teeth movement. The angle, at which force is applied to the gear, is close to perpendicular to the angle of main teeth force application, so all squishy materials get kinda pulled apart and jammed. As you can see, slavs deal with insecurity of bulky stupid designs using more bulk
I'd like to see the video where someone demonstrated that it is "pecker-proof". OK, maybe I don't want to ever see it.
@@ericcsuf Oh boy! Finally! Now those damn criminals can't go around sticking their peckers in every lock they see!
Interesting I imagine some even have a "stepped" key way that look like a grate to keep non key items out.
If you're pickin' with your pecker you're really in a pickle.
Please tell me you’re still alive
"Shoving carrots into the locks, yes this is the peak of Angus's career"
Oh, we don't know that. He could be shoving muffins into locks next week.
He could probably make a whole channel dedicated to shoving carrots into various openings. Add a hydraulic press and it's basically a guaranteed success.
Locksmith lawyer would do it in a jiffy
@Oh Hai Lady Muse, I believe.
Maker's Wench not being particularly supportive of her man there 😂
I had that lock in my appartament. Key is good for self-defence too!
I thought that thing in your hand is a sword breaker?
@@DarrenC_1024 it's kinda universal. Swordbraker/jawbraker/soulbraker
Дмитрий spinebreaker/neckbreaker/planetbreaker/galacticdisassembler, ya know
I had that key on my phone before touch id.

Well, shoot, THIS was very cool! Thanks for the history lesson and showing off a cool design! Also, CARROT MURDERER!
I murdered so many... and in VAIN ! :(
"I gave up my kitchen for this?" Best line ever
Actually I found that person in the background who gave up her kitchen obnoxious and totally unsuportive. It ruined the video for me.
That commentary was where this video really shined 😂💛
better question, mother or girlfriend?
@@Duncan_Campbell Angus wouldn't have had to buy his own carrots if it was his girlfriend's kitchen!
@@Duncan_Campbell Psychology says lots of men hook up with women who remind them of their moms.
Using frozen carrots is key. It's Russia after all 😂. Great video Angus, thanks for sharing!
Of course Thierry. Frozen carrots are easier to hammer too lol
🤣🤣
Don't forget the corn oil.
@@4STEVEJOY34 Though it's not corn, but sunflower oil in Russia.
Was that pun intended? XD
How about a 4 sided version with a rightangle translation mechanism? I doubt if a burglar would arrive with 4 screwdrivers and would have the dexterity to manipulate all 4 sliders in a confined space.
hmm that sounds crazy enough to work! Could be interesting indeed.
@@MakersMuse do it Angus !
“Click out of one, counter-rotation, three is binding, back to two, click out of two, three, and we’re open” - LPL after 2 minutes with a 4-sided version...
@@JCCamp I made a possibly false assumption; namely that the four could not move independently. But maybe we are in 10,000 dollar gold-plated hammer territory. I don't see a real world solution, since if they do interlock in some way then brute force applied to any one component could open (or break) the lock.
(Side note: at one stage the UK education department used three interlocking gears in an cooperation campaign with a slogan like 'we all have to work together'. Of course they were hammered by thousands of parents and teachers and pupils (the supposed participants))
Key would still be huge and I doubt if it could work. However I would still try it.
Well, this was an ordinary garage and door lock in Russia and other post-ussr countries. This is called "ригельный замок", riegel lock, where "riegel" is an german word. The closest translation is "bolt lock" actually. "Rack lock" is a relatively new, it has not been used when this locks was popular. The lock is good with it's toughness, simplicity and extreme reliability, but the most important - it was (and still is) very cheap. But - very noisy, extremely easy to lockpick (usually a screwdriver or a steel nail were used) and if you lose the key, it will be easier to change the lock than to make a new key.

@@user-od4yl3rf4n Oh come on. I really hate that RUclips & Google Translate don't mesh at all. They're both owned by Google, they should mesh perfectly. Are you reading, Google? Get your shit together.

Ригельный замок это немного другое
I love whoever was continually roasting Angus as he was trying to use the carrot to open the lock. Also, I would definitely binge watch all of Maker's Muse Kitchen where Angus loses his fingertips.
I literally had a key that big I had to use in Russia.
Cool to see ya here :D
At least you literally couldn’t have it get lost
I don't know why she was complaining about giving up the kitchen.
She just made a mad roast in there.
Wow.. kitchen segment was HARSH!!
I didn't realize the carrots were supposed to be roasted.
Design a twisty version.
Like you did with the Dovetail puzzle.
Helical twist, good luck forcing that with a screwdriver!
Sigh... None of the ideas in my head are new. Oh well.
@@polychoron but you may be the first to put those ideas into a tangible form.
Yas the original screw design combined with this
It is called a Rack and Pinion.
Hello from Russia! Great video!
For some reason I expected this video to start "this is the lockpicking lawyer"
WOW Lady Muse! You’re a tough cookie!. Good thing he loves you. 😀
When I was younger (5 or 6), my father drove up to the fence and gave me the key to open the fence(same one in video). It was cold and in the winter. And inspite of these being great for cold weather, it had locked up, so I put force to it and it gave way. But our key didn't have a guard and a part of my index finger got stuck. And I remember screaming my head off from the pain. And instead of getting out to help me, my dad just drove the car up the driveway. And so I pulled my hand hard to get my finger out, only to RIP my skin. And I remembering crying, screaming, and running up a slushy, muddy driveway in the cold and in pain.
What a life lesson I tell you. Till today, I still can find that motovation that made me run up the driveway rather than stay crying like a little baby.
Hi Angus. In my country(I'm from Belarus) it uses a lot for locking some not really important doors in villages. I bet it uses in almost all Soviet countries even now :)
youtuber hammering a carrot...
I've seen everything
have you seen a llama doing a backflip?
A message from the SPCRT (Society for the Prevention of Cruelty to Roots and Tubers): If you carrot all for the sanctity of vegetable life, you would not force that poor root into unnatural shapes and positions for which it was never intended. Have some mercy on the tubers of the world! :)
Heh.. tuber tuber
@@VagabondTE You got it! :)
PETA be like:
That Pun Makes Me Want To Use Roots And Tubers In Ways They Were Not Intended For

I'm finna put all the carrots in a Wakefield accelerator and vaporize them. Mr Wakefield, how does it feel to destroy what you sought to protect?
6:25
her; "That's not going to work"
Him; "Why?"
me: "Duhh, the hammer is not big enough!"
Bigger hammer is always the answer!
Hi Angus, great find.
You'll also find this principal of bolting in the oil & gas or industry.
Their use is interlocking proces flow. So a freed key moves to the next step of a proces to open it's bolt.
This way the only right / safe way to sequence through a process is garenteed.
Temperature, sand, grit does little to effect their inner workings.
Lady Muse: the pinnacle of common sense (and bane of Angus' engineering prowess/sanity)
this is brilliant and is exactly what I needed to finish a design I have been working on for years to make a steampunk style clockwork treasure box.
it will make an amazing eye catching key and with the layout of the rest of the mechanism it will actually save me space.
My box is made to look cool more than actually be a practical lock, but that does not mean I don't want it to be functional.
Best of luck, sounds rad!
"I don't know why you tried it in the first place" ah Mrs. Muse, the voice of reason XD
Mumma-Muse!
i used to watch your channel about 2 years ago and since then the printer ive been using has been out of commission due to lack of interest and i want to get back into it. Maybe uploading a video on servicing old printers would be a nice idea.
This is kinda amazing how simple the design is
the non-stop banter had me in stitches.
Great video and Lady Muse pulling absolutely no punches!
This video should be titled, “Angus getting dunked on while stuffing carrots in locks.”
Loved this vid. The commentary was hilarious. I've never seen a lock like this and was totally amazed at it's working.
I'm going to print this mechanism out for my enjoyment. Thanks Angus. Stout follower of your channel. .
I'm using one in my workshop..but not the straight forward one..mine u have to stick it all the way in, then turn it 90° and pull back to make it work..great work, man! Keep it up! Luv ur channel! Just ordered my first ender, can't wait to start printing!
That's so cool looking, I Love watching you videos in the morning with a cup of coffee. Keep up the great videos
Very cool video. Nice info combined with 3D printing!
I LOVE the kitchen commentary.
Your locks turned out to be carrot-proof, but were they parsnip-proof? We need to know :)
I don’t need sleep I need answers
Are they leek proof?
Anonymous User Dang...
Congratulations on 500K!
I love how she's just like "I have up my kitchen for this"
Fun video! Your voice was sooooo deep during the kitchen part. Thanks to Mrs Muse for putting up with your silly project!
Is Mrs Muse his Mum or his wife? I suspect Mum as I don't think Angus would dare to not credit his wife, if he has one.
I would imagine it'd be a lot easier for the home machinist to do that style lock and perhaps that was another part of its appeal. I have yet to meet a Russian who doesn't understand the value of self reliance and given ther history who can blame them.
Absolutely, apparently it was a popular side hassle for machinists to sell at the weekend markets!
Cool 3D project!
In Soviet Russia new keys are made by the lock itself.
P.S. Your carrot is just not stiff enough, if you know what I mean ;)
😂
Hey Axel, do you have any web references (maybe English I hope) of the self keying lock? Thanks and good to see you here on RUclips.
@@jerryguardado5610 Sorry man, but i guess it was a joke) Something like "Russian doesn't make keys fo such locks, they just take a piece of metal and bump it in lock with a hammer, until it becomes a key")))
yeah, get a hot piece of steel and forge it on site haha!
" Let me get the hammer" proceeds to smash carrot in lock with hammer! Ha! That tickled my funny bone.
Another amazing video!
A frozen carrot might do better and would also make sense given the conditions this lock was designed to work under :)
Thank you Lady Muse to always fail Angus haircuts because Angus is awesome in his manner to impale creativity 💟
Is there an English version of this comment?
@@DisgruntledPigumon I am so sorry you may not know Vlad the Impaler. Like Vlad, Angus impales our creativity on the altar of DIY and Lady Muse impales Angus' haircut

Good they make carrots in the same color as the filament you are using!
Never seen a bolt like this before, Thank Angus. There is so much tec in the world that is not seen in other areas of the world.
One of your Russian subs actually has one of those and was initially very confused upon seeing it! And didn't think it would be *that* simple mechanically. Thanks, this was enlightening!
the 507 mechanical movements contains the sum of all human knowledge.

this lock: exists
507 mechanical movements: wait, thats illegal
Slick!
@John Doe Well, you see, the Shenzhen version of Hooters doesn't sell wings and burgers. It teaches 3d printing, CNC and electronics.
You're going into crazy rabbit holes lately which is interesting. Good way to demonstrate 3D printing capabilities.
I like your sarcastic kitchen very much. ^^
Cool vid and mechanisin. So close to 500k subs
This is really interesting! I always look at things from an artists perspective so of course my brain is like "this would make for some really fun key designs in some kind of cold environment for a game/story!"
Angus. You should make a little mini series called CAD Tuesday’s or something with small little CAD projects and how to’s for people wanting to make their own models. It doesn’t have to be anything complex but something short and sweet for your fans to consider.
These lock vids are fun to watch because I work in business and have to say that this lock was something what I have never seen. Would be nice to see you building Finnish Abloy lock.
This seems like it would be especially useful in a situation where the door is hidden. For example, a moving bookcase or a sliding floor panel. In those situations having a key hole in the wall is fairly obvious, but if you have to push the key into a hole all the way through to release the latch it could be in a gap between bricks or something similar. Unless you know what you were looking for you won't see it, so in this case I think it would be one of the most secure options for both hiding and locking a Panic Room.
I think this would be fun to put in to a puzzle box. Thank you for this idea.
Nice video! I must make one for teaching new specialists in forensic investigation center where I working.
In Poland there was a small private producer of that kind of locks. It was in 80' i believe. The company does not exist anymore. They were utilizing long and thin keys (ca. 100 x 12 x 3mm) , pushed thru a narrow, deep and precisely fitted slot. Because of that it was impolssible to apply any significant and controllable power to slide the bar. Bolts and spacings were precisely machined in brass with tight tolerances. These locks were almost impossiible to open without original key.
The lady talking in the background was cracking me up. 😂😂
Wow, it actually works! Somewhat
Thanks for sharing this interesting design 👍😀
"Hey dude let's hang out"
"Sorry man, I'm busy showing carrots into 3D printed obscure locks."
LOL! Loved the carrot part man. Super funny.
I wonder if you could design one to engage one rack in one direction when inserting it then turning it 90 degrees and engage a different rack on the outward stroke.
Or possibly having 4 different racks acting as pins in a huge core of a pin lock.
mraider94 My thoughts exactly! Or the insert stroke can operate a sliding interlock that prevents the bolt from moving, then rotate 90° and the extraction stroke operates the bolt.
So jealous of your fusion skills
Congrats on half a million
This might make the most Straight forward Keyblade
It's funny.. I used this type of key today for my garage door and now I'm seeing this video.
Angus's wife: looking at him like he's insane outta frame
Angus: IT CAN BE DONE
Amazing!!!
I gave up my kitchen for this.... Priceless!
That was gold! I thought the title was taking the piss. I’m glad too see I was right. Classic! 😂🇦🇺😎🍀
I've seen these things used in Western Australia on a few farms when I was a kid and in my teens. We had one on the shed door. Wasn't there really for security though. Just the mechanism that moved a larger sliding bolt than that pictured. It was old.
that gave me a good laugh, thanks Angus!
pretty neat heckling! You should make this a recurring segment. You stand in the kitchen and tryin' to shove vegetables into 3d prints, and the heckler does the rest.
Very cool.
yea we have these locks all over here in Russia/ Especially in the countryside
great video.
very interesing lock. enjoy your methods.
don`t listen to the negatives.
100 thumbs up.
You just gave me the solution to a problem I'm struggling for a year now!
this is my favorite video from you Angus :-) Thumbs up !! I love the Chef Cuisine part :-)
This totally needs to be a LockPickingLawyer collab.
Fair play for printing the mechanism in carrot colour.
If you made it so that the key must be inserted, dropped down, then pulled across the rack, that would make it significantly harder to pick with traditional tooling
I have a stupid idea but it makes sense to me and would probably make it kind of harder to lockpick I guess? Like if you make the keyhole part a lot taller so the key is actually a lot tall so the bolt gear piece is far off the the left of the actual keyhole. Then you turn the key and it would reach it cause it's long then you just push it straight in normally?
My grandma's apartment has a lock like this. You insert the key, rotate it 90°, then pull out engaging the teeth. It's carrot-proof.
Hi Angus. I just love when you get excited with the history of locks. Locksport is my #1 hobby, I have a locksport channel where I pick challenge locks that are sent to me from around the world. 3d printing is also a big hobby of mine with 6 machines. The two go together very well. I print a ton of locksport tools for the community. I've already printed both of the pin tumblers you designed a while back, there in my collection. Of course this is another awesome design I just had to have. If I do decide to feature them on my channel some day you'll definitely get all credit for the designs. I can't wait to see what you come up with next. Enjoy your weekend my friend take care.
All the doors at our families old ranch have these types of locks. There is a different key for different types of buildings too. Makes sense to being this ranch is in the hard country of north west Wyoming (USA) where winters can be hella cold! Really the only thing they needed to keep out was bears but back in the day they hired some rather shady ranch hands and that was the reason for the different types of keys. Still as my grandma said they only kept out the honest.
As with most locks I suppose, thanks for the insight!
haha nice :D
how about a 'circular' lock with this technique? :p (like a rotating disc in the 'door')
That could deform the grooves in a way that makes them difficult to design a key for, but it would certainly be fun to try.
That would probably be a very course pitch multi start Acme or square tooth screw and nut.
Yes, this is a form of crossed helical gearing, except the straight rack is essentially a gear with infinite radius. This will work with a basic involute gear and a corresponding straight tooth rack. It would be a little more complicated than the basic design since the gear part would then need to be connected to the bolt to open it, or some kind of rotating lock with locking lugs.
Doesn't that already exist in the form of disc detainer locks?
It would probably be more secure against screwdrivers... not sure about soft carrots...
I WANT THAT BOOK!
good job
Nice to hear lady muse again
We had a lock like that back in the 90s. The spring was really strong and the key had *only* sharp edges, and getting in and *out* of the building was a nightmare.
dont let anyone get away with discouraging your enthusiasm
Oooh my grandparent's old garage has that lock, its a bit odd to use but still works
Interesting video. Never knew I could grow spare keys in the garden...
Hmm we should send this to the lock picking lawyer
Edit: nevermind I should have whatched the video completely before commenting
This is the lock picking lawyer and today I'll be picking a lock with a carrot.
@@Fenyx4 and "have a nice day".
I have a feeling that if you took the time you could make a game out those rack locks. Make some similar locks and keys and race to find it. Another option is make a puzzle out of them. That simple mechanism is very versatile
We need more off camera commentary!
This kind of lock would be cool in a fantasy setting.
I can already picture a variation with a triangular prism shaped key with the notches carved into the 3 edges.
6:40 welcome to Maker's Muse Chef edition, where Angus will slowly and inefficiently shred a carrot
