I suspect the people creating locks are locksmiths and the people making them have real machining skills, and between them they could create A lock that's very difficult to pick like this one. They have, this is not the first to stump Bill. The real issue is is it commercially reproducible at a price it's worth to enough consumers. You spend a few+ hours making this for fun that's one thing, but a few extra minutes or more of production per lock when you're trying to produce enough locks for enough people who will pay enough money to keep you in the black is something else. I can't say for sure, but I suspect these would have to be expensive locks to produce commercially, which means sales to fewer consumers. The commerce question is always is the extra time to produce worth enough money to a enough consumers to turn a profit. Unless of course, you're a democrat, in which case any amount of someone else's money is well worth what I want.
It's a false set trap. You have to out right pick it without using the false set. If you don't the sleeve prevents the other pins from going in the the Bible. Amazing lock!! You gave it one hell of a try Bill.
Just think how much stronger your average lock would be if floating sleeves were standard. Relatively cheap to mass produce, and it doesn't seem like it should open it up to other vulnerabilities either, though I'm far from an expert.
Just thinking about dealing with the cutting forces on some of those thin pieces makes me shudder. Everything flexing and bending, plus the slow speeds on those super deep spools. I can't imagine how much time this took. I bet there were quite a few broken parts as well as ones out of tolerance. Amazingly well done!
As a machinist who is also training to be a locksmith this video is captivating. I'm feeling inspired. 😈 (hopefully my skills shine half as good a this.)
The Best lock, as well as Arrow and other multi-shearline locks, DO have a second sleeve but is is not "floating. Instead, in those locks the sleeves are both attached to the actuator and can either open the lock (operating sleeve) or remove the core (control sleeve). Basically, it is an updated master ring lock with two separate and different keys. If you are really interested, grab yourself a Best core and gut it. That is the fastest way to understanding how multi-shearline locks work.
As one machinist to another, respect is due - Beautiful work here. No wonder it was a tricky one to pick, it's got a lovely assortment of tricky pins, plus threading and the sleeve just multiplies the horror by about 100. What a delight to see but I'd rather not have to open one of these :D
The amount of play in cylinder made me wonder. It seemed really loose, which might indicate "sloppy machining", but that was far from the truth. That is among the most precisely machined cylinders and pins I've seen. The difficulty Bill had getting the pins out is a testament to the close tolerances. The sleeve around the cylinder made things look sloppy, which is actually a very effective security feature. That lock is a beautifully machined piece of art. I've seen LPL pick challenge locks, so I'm confused by the @tuba7084 comment.
That is one very clever and talented piece of lock making and absolutely first class machining . Just looking at the thought that went into it bends my brain quite a fair bit . Go Scott
Huge counter rotation, could see it so clearly thanks to those marks - fantastic idea. One of the best challenge locks I've seen. Lovely presentation too.
Those pins are Gorgeous i would consider that a masterpiece done by a true Artisan I can't say enough Great Work!! I'm sure Mr.Bill feels honored to be whipped by that beautiful piece of artwork I know I'd be
LOOOOVE THESE KINDS OF VIDEOS!! SOOO AWESOME!! Bill, before you return the whipped locks, do you try to beat them again? Now that you know their secrets?
I really don't think it would make that much of a difference. Unless you could avoid the pins trapping against that sleeve by knowing the bitting (and having the skill to raise them there), you'd have to be very, very lucky to get an open.
@@bosnianbill You could probably reduce the effect of the sleeve, if not eliminate it altogether, by putting something in the bottom of the keyway to line it up the same way the key does. Maybe as part of a purpose-made tensioner.
Scott Armstrong is a lock-artist! That is some of the most beautiful work I've seen in a long, long time. If Master lock ever wanted to up their game, they should take note, or maybe just offer Mr. Armstrong a job.
Most of these craft made locksport locks wouldn't fly at all as commercial locks, but just taken as puzzles Scott Armstrong's work is nothing short of phenomenal. Just amazing machining quality.
Impressive machine work to make those pins and design the sleeve. Great job BB at attempting pick such a beautifully made pin set especially since you had no idea what was actually waiting inside the lock.
Bosnianbill to clarify, others have also.. but, this one gets my attention, me being a fabricator and all. good job. thanks for all you do for the locksport community Bill !!
I don't think you'll ever be challenged by anything this complex and beautiful again. A unique work of art, you really shouldn't feel bad, that was impossible to pick
WOW!!! What an amazing piece of work. I think the best challenge lock I've seen on this channel, and there's been some tremendously good challenge locks on this channel. Absolutely fantastic job Scott, very well done man! 👌👌
So I walked away for just a few seconds at the start of this video, came back and enjoyed the rest of it. About 10 minutes in, the alarm in my phone goes off and scares the _shit_ outta me. I'm sitting here thinking I'm haunted, checking my alarm settings and I do _not_ have an alarm set at the time it went off. ...I go back and watch the video again, and here's Bill asking Siri to set a 10 minute timer. Goddamn you @Bosnianbill! You owe me new pants, brother!
I felt exactly the same way as soon as I opened the package. When I saw the specialized tools, as well as the beautifully executed lock housing, I suspected I was in trouble...😀
Well.. If you aim to whip BosnianBill it seems such variations are necessary. If I remember right I see him picking locks with floating sleeves and other locks full of crazy assa-like pins.. So if you mix the two things the result is a crazy lock 😉
With the awesome skill displayed with these challenge locks, im starting to think Machinist vs. Locksmith would be the next great marvel super hero movie! As an extreme amateur of these trades, I continue to be amazed... and extremely envious of the talent! Badass work and design Scott! Excellent attempt Bill, glad you are no longer beating yourself up over "just a 5 pin lock". That thing was a killer!
That makes for hone heck of a lock. Looks like you would have to use something in the bottom of the keyway to force the sleeve to align correctly but not knowing it is there would make that difficult to do. I am thinking about getting a little mini lathe for a project and making some keypins may be in my future.
I was looking to pick a disc lock, lost key which you pick in seconds. Then I watched you take apart a very complicated lock. looked more like art than a lock. In short I have a grater understanding of locks & how they work
I offer great applause for the very fine machine work. The pins are all very sharp and clean in design and production. I also like the fact that the plug plus sleeve total diameter equals the original thickness of the plug. This potentially makes it easier to rekey with a standard follower. The key at the bottom, coming through the slot in the sleeve, will keep the top pins from falling down into the slot. If a picker uses a thick turning tool that wedges at the bottom of the keyway, he can turn the plug and sleeve at the same time. This would invalidate the value of the sleeve's contribution to pick resistance. But, he would also have to know that it has the sleeve ahead of time and the extreme security pins will still be a huge obstacle to beat.
Wow Scott, that is by far the best job on a practice lock I have seen on here. You my friend have skills . I sure hope Master Junk has been watching. Mr. Bill ì think you picked it, but that side pin held you back. Nice effort on it.🔒
From one extreme to another the last lock you picked Adam Sweden was a mess and this one is a work of art. Adam I if your watching take a very good look and take notes. ( that goes for anyone else that wants to butcher a lock). Everything about this lock is stunning right down to the presentation. Again thanks Scott for the lesson in doing it right.
Awesome job, as a machinist I must say this guy really does awesome work, those sharp edges on something so small are not easy, and the fit of that sleeve. Thanks for sharing this beautiful work.
Bill, it looks like (in your presentation of the guts) you had driver pins 2 and 4 upside-down. The steps of the multi-step pin were closer to the key pin, and the dual spring pressed on each part of the pin-in-pin independently. Re-installing them incorrectly would probably reduce any additional security their special features provided.
Man, why don't all home locks come with this sleve?! It's not that expensive, but secure as hell...! Master's and other junk I understand, but an $80-100 door lock ought to have this...
Most homes in America have $20-$30 locks though thanks to the ever-present thought that locks "just keep honest people honest." I really wish people would figure out what reasonable security really looks like.
My town house was broken in 3x in college, all over holidays and i assume by the same people. They only got things the first time, but they never went in through doorways, always a broken window. From mine and other peoples experience thief’s will always take the easy way unless it is something in particular they are after, but then they wouldn’t really be the run of the mill thief.
Riley Fenley But did your house have any kind of security system on the windows, like some kind of alarm connected to them? That's not too difficult to arrange, doesn't take that much power, but a broken 'strip' in a window alerting of a break-in works wonders.
Michael Berthelsen the first time no, the second and third yes, a full alarm with window sensors. I also got spot lights added on the side where the break in happened (it was the end unit). I also would call and ask for extra police presence in my area because of the previous break in. I’m not saying good locks aren’t a good investment, but it is more than likely not the way they are going in.

Wow, best presentation ever and a tough lock!😨 Amazing machine work, the work of a pro who's just up'd the standard. Way cool.😎🍺✌
He put some serious work into that on. That lock is way beyond my abilities.
Jubal Early very true, more that I could do too!
Don'z Lockz you should send that lock to LPL tell him that research is not allowed.. I think he might get stumped on that one as well..
@FoxRcng708, that's a really classy comment, fella.
There is no Fox racing that I can see
I was wondering what a locksmith with real machining skills could accomplish with a lock, and here I have the answer, an impressive work indeed.
I suspect the people creating locks are locksmiths and the people making them have real machining skills, and between them they could create A lock that's very difficult to pick like this one. They have, this is not the first to stump Bill. The real issue is is it commercially reproducible at a price it's worth to enough consumers.

so its pickable
lPlanetarizado yes but it would take patience and a very light touch. Figuring out the lowest set pin first would be half the battle.
Just think how much stronger your average lock would be if floating sleeves were standard. Relatively cheap to mass produce, and it doesn't seem like it should open it up to other vulnerabilities either, though I'm far from an expert.
WOW!!! As a machinist, I know working with tight tolerances. Just watching all this work makes me want to tip my hat at this incredible work!!!!!!!!
I agree! I THOUGHT I was a machinist until seeing THIS. Now I feel like a wannabe clown.
+Bosnianbill You so nonchalantly made that comment about having blood on your hands, and have access to a crazy arsenal. WHAT DO YOU DO!?!?!?!?

I like that we can hear the amazement and respect as you're pulling it apart. That is a seriously cool lock and deserves the whipped video. Fantastic!
I really was blown away by the intricacy of the craftsmanship on this one! I am....envious. To the EXTREME!
@@bosnianbill is this "floating sleeve" how the separate shear line on a Best Lock is achieved? The control/operation difference has me intrigued.
The Best lock, as well as Arrow and other multi-shearline locks, DO have a second sleeve but is is not "floating.

Is it even possible?
Larry Be never say never, but I’m not commuting to “Yes” just yet.
Maybe LPL can try?
Unfortunately LPL doesn’t feature challenge locks on his channel. He is definitely up there with the best of them for picking though.
Would he have the blind disadvantage Bill had by not seeing its innards?
The amount of play in cylinder made me wonder. It seemed really loose, which might indicate "sloppy machining", but that was far from the truth. That is among the most precisely machined cylinders and pins I've seen. The difficulty Bill had getting the pins out is a testament to the close tolerances. The sleeve around the cylinder made things look sloppy, which is actually a very effective security feature. That lock is a beautifully machined piece of art. I've seen LPL pick challenge locks, so I'm confused by the @tuba7084 comment.
Yeah exactly, thats head and shoulders the best challenge lock I've ever seen. Take a bow, son!
The magnetic handle! It's for pin extraction! They're all steel! Use the handle Bill!
Okay, I'm done shouting at the screen :D
That is a work of art! Truly custom level lock. Blows a factory made lock away! Beautiful workmanship! And I was a whipped by lock on top! Awesome!
That is one very clever and talented piece of lock making and absolutely first class machining . Just looking at the thought that went into it bends my brain quite a fair bit . Go Scott
The introductions in the locklab song are so extra. Locklab is truly where the fun begins you get the rowdiest crowd picking locks
Next challenge for Scott is to replace the single sleeve with separate sections of sleeve for each of (or maybe pairs of) the pins.
Your thought process is bound to make my life harder... I am banning you for having too much creativity, initiative and original thought. 😋
OK Satan, that'll be enough from you! :)
Exactly my thoughts. Also, maybe make one sleeve grab the next one or make it move in opposite direction to seize the rest of the pins! ))
@anomicworld Puzzles, the original locks of chinese boxes... the next level up. Go for it!
Huge counter rotation, could see it so clearly thanks to those marks - fantastic idea.
One of the best challenge locks I've seen. Lovely presentation too.
Absolutely breathtaking. Never seen a nicer lock. Great work Scott!
AWESOME machine work Scott!!
The full presentation with the block and tools is remarkable!
That is the most amazing work, the machining was great, blows many high security locks out of the water. Thanks Bill 👍🏻
Awesome videos. I get to watch them once in a while and they never disappoint.
Those pins are Gorgeous i would consider that a masterpiece done by a true Artisan I can't say enough Great Work!! I'm sure Mr.Bill feels honored to be whipped by that beautiful piece of artwork I know I'd be
Well, I don't like being beat, but when something this well done does it, I don't feel nearly as bad.😀👍
LOOOOVE THESE KINDS OF VIDEOS!! SOOO AWESOME!!
Bill, before you return the whipped locks, do you try to beat them again? Now that you know their secrets?
I really don't think it would make that much of a difference. Unless you could avoid the pins trapping against that sleeve by knowing the bitting (and having the skill to raise them there), you'd have to be very, very lucky to get an open.
Bosnianbill I wondered in a comment earlier if this lock was actually pickable. There's the answer. ☺What a cool lock.
I was wondering the same thing. It is an advantage to know the internal construction. I'm amazed that such a simple modification is so effective.
@@bosnianbill You could probably reduce the effect of the sleeve, if not eliminate it altogether, by putting something in the bottom of the keyway to line it up the same way the key does. Maybe as part of a purpose-made tensioner.

Masterful Workmanship Mr. Scott Armstrong -- Beautiful to see!
That is an awesome lock! I hope lock manufacturer's watch this and take notes. I really like all the attention to detail that was put into this lock.

Scott is a true craftsman, great presentation and a great design that is well executed. Tough gig Bill.
I watch a lot of lock vids. This may be my fav. Well done.

Great video. Wow on Scott Armstrong’s machining skill. He has some really innovative tech in his lock.
Wow!
That was impressive from start to finish!
From the packing to the design it was all very well done!
I am gobsmacked over the machine work. Deep respect on everything Mr. Armstrong.

Old technology is sometimes the best technology
Lovely work on that and good effort picking it Bill, really really nice.
That was hands down some of the best machineing and presentation I've seen on the channel. Amazing work Scott!
This is probably one of the best locks I have seen because with that standard pin in the 1 slot, it looks so inviting.
Great presentation and great work on the lock
The work of an artist! Just beautiful
Ultimate challenge lock. One of a kind. So cool to see how it works.
Fantastic work, Scott. No shame in losing to this one, Bill.
This was one of the most beautiful things I have ever seen. I need a workshop with machines.
Beautiful lock 🔒
Beautiful, nice work Scott!
This challenge lock is just perfect ... all is so nice ... congrats Scott
One of the coolest locks ever seen full of wicked pins.. Totally amazing! Great job!!!
Would so many variations be necessary in this set-up?
Well.. If you aim to whip BosnianBill it seems such variations are necessary. If I remember right I see him picking locks with floating sleeves and other locks full of crazy assa-like pins.. So if you mix the two things the result is a crazy lock 😉
Beautifully done.... one of the best...
This guy is a machinist, the first I have seen here! Great work!
A Freekin work of art! Great video!
Amazing enclosure and fantastic job on the pins
This has got to be the coolest lock I've watched you gut. Well done!!

I had a similar idea, but neither the skills nor the tools to pull it off. Beautiful work.
That is a legit challenge lock. Great work.
Wow. That was a beast. You were done for from the first false set, if that sleeve gets inside one of those spools it's game over. Absolutely insane.
That makes for hone heck of a lock. Looks like you would have to use something in the bottom of the keyway to force the sleeve to align correctly but not knowing it is there would make that difficult to do.

It's always good to see you have fun gutting a lock!
This has the air of a good magic trick. After you learn how it's done, you're even more amazed.
My god thats gorgeous. The standard pin upfront to throw you off just shows the level of thought thats in this lock.
Wow, a lot of work went into that one. So awesome!
Beautiful workmanship and very well planned design. No shame at all not picking that one.
Beautifull work! And those pins where really great i think. Like a "BigBoy" no.2
Wow. Beautiful work. Now thats a challenge lock. I wish i had some of that skill
Hats off to Scott, that has to most impressive challenge lock Bill has ever had in his hands, no shame in being whipped by this masterpiece!
Thank you for sharing, that Lock is incredible and beautifully presented. All around a perfect lock, perfect video thank you

Just awesome Bill..Great machine work not a amateur for sure ..thanks for the Great video buddy. 🌟⭐🌟⭐🌟😎
Impressive metal working skills. I've been a machinist in a former life and I'm impressed
Wow, what a challenge lock....
You sir have my respect for that one
Simply speechless that's beautiful
Nice one Scott! I need one of these locks!
Great look bill. That guy should be working with one of these big companies as an advisor. They could learn a lot from him.
That was effing gnarly. Good job bill. Props to Scott ad well.
Bill your knowledge is awesome thanks for sharing
That's some beautiful turning!
A master piece challenge lock! Hat off!
I always dreamed of something like this ,simply amazing 😮
From one extreme to another the last lock you picked Adam Sweden was a mess and this one is a work of art. Adam I if your watching take a very good look and take notes. ( that goes for anyone else that wants to butcher a lock). Everything about this lock is stunning right down to the presentation. Again thanks Scott for the lesson in doing it right.
Wow! Simply, WOW!
Really great work on the lock. It would be interesting to see another try at it now that you know how it's built to see how difficult it really is.
Hell of a job Scott.
A well deserved victory to Scott. That was some fine work.
Beautiful lock!
That is one slick lock. Very cool.
Awesome job, as a machinist I must say this guy really does awesome work, those sharp edges on something so small are not easy, and the fit of that sleeve. Thanks for sharing this beautiful work.
The follower he supplied is the stock he used for the sleeve. Awesome micro machining from Scott Armstrong!!!!!
The second Top pin, should be called a "Wine Glass" pin. This guy created some amazing work of art here. Time went into this one. Great video!
Wine glasses aren't stepped. How about "Hanoi pin" after the towers of Hanoi?
Amazing work. Master Lock needs to hire him.
Bill, it looks like (in your presentation of the guts) you had driver pins 2 and 4 upside-down. The steps of the multi-step pin were closer to the key pin, and the dual spring pressed on each part of the pin-in-pin independently. Re-installing them incorrectly would probably reduce any additional security their special features provided.
Wow! That is going to be VERY tough act to follow! To say I would hate to summit a challenge lock after that work of art would be an understatement!
excellent custom lock
