Aerospace Engineer here - I work in industrial control systems, robotics and automation one of the greatest bug bears I have with younger engineers and its most prevalent with mechanical engineers is understanding tolerances. I have lost count of how many times one of them has asked me if I can "fix it in software" when they have screwed up. Tolerances are the thing that makes machines work or NOT work and fail usually in the worst way possible. Its actually one of the cornerstones for Quality Assurance (QA) and when you consider how Boeing have done with their QA recently its a bigger issue than most people realise. The fact an engineer this young has such a good understanding of the topic is very impressive. First it means he was obviously LISTENING in class and that's a lot rarer than most non-engineers realise. Most of them are daydreaming about how they are going to change the world and yes I was guilty of that too. He's done another video and his explanation of the lock is pretty impressive. What he's doing is tackling the issue of standard lockpicking which is being able to tension the barrel and manipulate the pins. He even does a good job of explaining why those standard attacks work and how tolerances play a part in that. *ALSO* in that video he references what Shane on the YT Channel *Stuff Made Here* challenged the Lockpicking Laywer with. So I am certain he knows who the LPL is and we should expect a video form there soon. My bet will be that the LPL finds a way around the geometry he's put in place like he did with Stuff Made Here's lock. A couple of people have suggested some kind of kinetic attack to the the watchdog to rotate properly. OR He'll make a special tool like he's done for the Disc-detainer locks. If this were to go into production it will have a higher cost for the simple reason that it has higher tolerance demands and there's more parts to be made. So if it comes to market it will be in high end locks where people want more security.
@@jakobrosenqvist4691 As I said I'm Australian but was in Canada for a project back in late 2017. One day the Canadian controls system guy doing the other part of the plant got "one of those" phone calls. When I asked, he explained and I replied "Yeah the most often asked question to a control system engineer: _Can you fix that in software?"_ He just sat there and laughed. No matter where in the world we work or what industry or what PLC/DCS/Robot system we are on we'll get asked that at some point. I bet when one of the blocks on one of the Pyramids didn't fit some over promoted vizier asked if it could be fixed in software.
@@jakobrosenqvist4691 My mother who was a High School teacher told me something very important one day. I forget the actual specific event but it was where a woman/girl had viciously treated another woman/girl and she said words to the effect. _"Women can be there own worst enemy. Even worse than men."_ When I asked she then explained to me that within any group of people (cultural, tribal or professional) there are those few who play "politics" but play it at a very nasty level. Think Little Finger from Game of Thrones. They are willing to throw anyone else the bus if it helps them in that moment and then drive the bus back over them to make certain. In engineering its the guy who asks for a software change and then goes off to a project meeting and says something like _"they're working out the software"_ with the implication that the delay is a software bug NOT a modification to fix something and that its the fault of the control systems people. *I've actually had people do that to me in project meetings. Before I could even get a word in I have had senior managers turn on me, howling about how "its always a software bug" and then be threatened.* So yeah I have this issue with a CERTAIN type of engineer. As one guy I worked with put it: _"They build it and f*ck it. We fix it and make it work."_ The bit he left out was "They claim credit it when it works and blame us when it doesn't."

I'm an aerospace engineer who works in industrial control systems and automation and you're right his explanation of tolerances is damn good. I am actually damn impressed that someone so young gets it this well as I have seen many engineers NOT understand tolerances so many times that it feels like its a contagious disease at times. This is only his second video so he's new to YT and that video is pretty good at explaining how tolerances make tension & pin manipulation lockpicking what it is. The real question will be what can someone like the Lock Picking Lawyer do with it.
I did something a lot like this, but rather than putting the shear lines on concentric tumblers I put separate tumblers on either end of the pin stacks and then coupled the two tumblers together with noncircular gears. The noncircular coupling means that fast movement on the keyway results in slow movement on the test tumbler; so by the time the test shear line begins to bind, the keyway should have turned so far that you can't change how many master pins it has captured. Once that's off-axis the ratio speeds up so you don't have to turn the key too far. I didn't go far with fabrication, though. I just pressed the keyways of two separate locks together and stabilised them with clay, and then set the project aside while I tried to figure out a better gearing system which left clearance for the mounting bolts. Videos in my channel.
Beautiful lock, and must also say you have such a good way of explaining things, truly great at teaching. Thank you for all your great videos. Keep it up. :)
I am concerned about the potential for over-lifting, but you did a wonderful job here. As I'm sure you know, the LPL is widely considered the final UA-cam authority on lock quality.
Great production quality, awesome coverage of tolerance optimization. I hope to see your sub count rise! I have two unpickable lock designs in the works at the moment but neither uses standard key or core geometries. I intend to prototype one with 3D printing but will probably never attempt metal as while it's technically intentionally manufacturable with machining, it involves an excessive number of setups & operations. The other is at least mostly inspired by existing core and key geometries and should fit in the conventional deadbolt enclosure. I intend to try and machine the second myself in the coming years. Keep up the good content!
2:53 What you're calling a mid-core looks extremely similar to the Master Ring on a Mogul prison lock, although you're implementing it differently. In a Mogul, the change key engages the normal center-most shear line. Inserting the master key locks the inner core to the master ring and engages the outer shear line. Both shear lines turn the same cam that operates the door lock. I don't know if you were already familiar with the Mogul prison locks, but it's an strikingly similar piece.
As i commented in the last video, bind both cores in some way, pick the lock, then unbind the cores as you keep tension. The last pin will just slide in the correct position.
Send your lock to the "Lock Picking Lawyer". If he cant pick it then you have something, if he can then your design is just another attempt at creating a unpickable lock.

This channel has potential! I love how new channels are starting to build on the work of previous ones, I feel like the use of Manim is immediately indicative of a good channel. In terms of possible attack vectors, one that I haven't seen mentioned and a potential weakness of using standard keys is visually copying. In an age where everyone has a camera with them at all times, if you're being targeted specifically (e.g. by a stalker) that could be an issue. Obviously you could simply hide your keys at all times but an overengineered solution like a hiden key bit or retracting sleeve would be much more fun.
If you are considering tolerance and viability, you should also consider the past of time using the system, because it is very known that the keys wear out
Kid, you have potential! I'm subscribing! I can see you're a good designer, but what matters most for UA-cam is being a good presenter, and you're amazing! Keep expanding your workshop and your horizons, and I think you'll go far!
A quick suggestion. Traditional locks have bad tolerances because a drill doesn't just have to work on a cylindrical surface; it's the same drill making thousands of holes, day in day out. Wouldn't it be better to make a flat area on the cylinder, make a pilot hole with an industrial laser and THEN let a hardened drill bit work on the brass parts while it's turned to round again afterwards? If you could get the alignment 80% closer together then I can assure there will be much less feedback.
am I wrong or correct to think this particular design only capable of opening the bolt ? also I think a really thin shim could be inserted between the midcore and the body to pick the pins
Yes, you are correct. That is a downside to this design, single direction operation similar to disc detainer locks isn't necessary the end of the world but is an important limitation. I also agree that a shim between the midcore and shell would be quite destructive. How do you suggest inserting such a shim? Thanks for watching!
It's a sad state of affairs when individuals are more concerned about security than billion-dollar "security" companies. Although I do have to take exception with your statement that lock companies have gotten complacent. I don't think it's complacency at all. They know very well that their products are flawed. They intentionally produce products they know are flawed simply because it's more profitable than producing products which are actually secure, and they know that people don't have any alternative.
Have you figured out a way to share you 3D designs with hobbyists in a format that can be edited and merged with other people? I've been looking for a good solution for years. I originally published my own open source lock design as Blender 3D scene but as Blender officially doesn't support CAD style modeling, modifying the design is a bit weird and it seems that other people weren't willing to learn it. On the other hand, easy to use CAD tools suchs as Fusion 360 and Onshape are either really expensive or cloud-only and definitely not open source. FreeCAD has such a weird UI that I still cannot effectively use it even though I can successfully create designs in Blender, Fusion 360 and Onshape.
I'm unclear why you need a clocking pin. Can you not just put hard stops on the cam that lifts the watchdog pin that bind on the side of the watchdog pin once it's at the proper height and have that serve both purposes? I think then you can prevent the mid-core from over-rotating with a simpler hard-stop which interacts with only the mid-core (I don't think there's any reason to hard-stop the inner core, that action is normal). The mid-core hard stop is a problem, though, since you normally expect a lock to work both ways from home, one way to lock and the other way to unlock a deadbolt. I can imagine mechanisms that would handle this with two watchdogs, asymmetric cams, and escape paths for each watchdog in different directions acting as hard stops, but that's way too fiddly.

@@lordtony8276 anyone in LPU with a black belt has picked locks more difficult (and more of them too) than anything lpl has on his channel. Lpl picks mostly easy locks and rarely a few moderately hard ones.
It's kinda bonkers how much effort you went in to just to make video about how your lock works... you learned manim just to make few animations + some additional video edditing software...
