Adam Savage's Miniature Vault Door Build!

Adam embarks on his next multi-stage build project: a 1/12 scale working recreation of a mechanical vault door! Inspired by his recent acquisition of an automatic hacksaw that can cut the solid cast iron cylinder that will become the vault door, Adam pulls from his extensive research into the operation and gearing of these doors to start making his scaled replica. The first step: machining the central ring and spur gears from which the locking pins will activate the vault lock!

[@Aviertje]

When I read the title, I thought that Adam was recreating a Fallout vault door given how nicely that show has popped off.

[@zeroxception]

I thought the same

[@fromthistexasbreath]

I knew that it would be either a Fallout door, yes, or it would be exactly this, a solid metal mechanical miniature of a seemingly mundane thing haha. Those are the two possible options with Mr Savage.

[@jeromethiel4323]

Indeed. Especially if it was from the real fallouts, fallout 1 and 2. Those doors were epic looking. The Bethesda vault doors are okay, but they lack the charm of the originals. What would be epic, would be to have the claw from FO1 or 2 come out from the side, engage the center, and roll the door open on the floor track. I would pay a fair amount of money to see one done correctly. Maybe not enough to have someone custom make one, as i imagine the man hours would kill a project like that. I doubt i could get a maker to make a metal fallout vault door for $500 or less. The labor alone would be worth more than $500. But i guy can dream. Maybe somebody with a decent CNC machine could make one for that price, but even then, a lot of the work would be hand fitting and designing. Unless the maker were going to make a run of, say 100 or so, the design time would kill the project.

I worked as a bank teller for a couple years at the start of my career. I always got a thrill when I got to set the clocks on the vault doors at closing in the evenings. This was less than 10 years ago, and it blew my mind that such primitive mechanical technology was still the best way to ensure things were secure even in our modern digital age.

Fun fact. In industrial gear boxes that run at hundreds of RPM for years at a time, we actively seek out gear tooth combinations with no common factors, preferring prime numbers of gear teeth. These sets of gears wear more evenly over time. Definitely not the same design constraints that drove the gear tooth counts for vault doors!

[@dodaexploda]

It might be the difference between profession and hobby. I'm not sure Adam did much machining for props, and when making props I get the impression that being on the clock and getting things done was super important. I only realized this recently with my profession. A lack of perfection and more happy that my work does what it's supposed to do. But stuff for my hobbies has no clock. I'm not charging anyone for my time. I can take all of the time I want and be as big of a perfectionist as I want.

[@iowa_don]

I had a situation like that where the vanity doors of my bathroom cabinet got damaged on the upper edge. I thought I'd have to replace the entire vanity as there would be no way to match the doors. My friend Dave says "take the doors off and put them back upside down". Beautiful out of the box thinking!

[@JimRobinson-pr3bu]

Adam I know a man who is probably the last living installer and technician for Diebold and Mosler round vault doors. He owns a business that deals exclusively with used and antique safes from the late 1880s into the 1980s. I’ve worked with him in the past and was a wealth of information.

[@EnteringTheMostHoly]

My dad worked for Mosler. He left the company and helped Marlin Smith start Smith Banc Equipment, many years later Marlin sold the company and my dad continued to work for the new company. Marlin started up another company Smith Hamilton. Marlin passed away in 2020. My dad Jim Arnett passed away in 2021. My dad was one of the best out there. When a bank needed someone to break open their vault he was the one they called on. He worked for 30 yrs. After he retired many still called him to open up old safes. I have a lot of cool stories about him.

Nice 👍🏻 Yea i was gonna post that Adam should chat to Deev! (Deviant Ollam for those reading who may not know).

[@victor-charlesscafati]

153 isn't prime, and I determined that almost instantly with a little math trick. If you add up all the digits of a number, and then do that again (if necessary, over and over) until you have a single digit (the "digital root" of the original number), if that remaining digit is divisible by 3 (that is to say a 3, 6 or 9), then the original number is divisible by 3. In this case 1 + 5 + 3 = 9 so it is divisible by 3 and not prime. Another example would be 23643: 2+3+6+4+3 = 18 and 1+8 = 9, so it is also divisible by 3.

[@Engitainment]

Oh That makes my brain happy, thank you for teaching that!

[@gloriousapplebees]

Ooh that's awesome! Thank you. I just pulled out a Calc real quick and hit /9 as a guess and saw nope not prime

[@ReverendTed]

Yep! I had the same reaction. "Hold on, I know a trick...nope." After a second I also realized it's 150 (easily divisible by 3) plus 3.

[@njohnsonII]

This is awesome!

[@MooCow2X2]

I just mentally went. “153. 50x3 + 1x3”. Nope. Not prime. I’d forgotten that other trick Hopefully I won’t forget it again!

[@conorgibbons98]

There’s a H&M here in Dublin (Ireland) that is occupying an old bank, and downstairs in the man’s section, there’s a room that used to be the vault, but they kept the door. It’s a huge, square, heavy, thick metal door and it has the pins protruding. It’s really cool

[@benjaminturner643]

There is a guitar store in Morristown Tennessee called Guitar Vault. It was an old bank and they kept the door.

[@elevown]

I think anyone who sets up in an ex bank will choose to do the same. Setting aside it looks cool, as Adam mentioned its a HUGE difficult- and probably very expensive task to get a vault removed. Its so much simpler to just repurpose the room.

[@ReverendTed]

I may be mistaken, but I suspect it's built that way because base 12 is one of those numbers that makes for convenient math (being evenly divisible by 2, 3, 4, and 6), which is why we divide time in 12's, 24's, and 60's, and circles into 360 degrees. (60 being especially convenient because it adds in divisibility by 5.) So in other words, having it in base 12 means you can evenly split it in half, 3rds, quarters, or 6ths, and since circles are already measured into 360 degrees, using base 12 means it's easy to design for a circle. So they probably didn't say "we need to design this so it'll work well on a dividing head", but rather dividing heads are built the way they are for "math reasons", and the vault is designed that way for the same math reasons.

[@splendidcolors]

That was what I thought too,

[@awandererfromys1680]

Yea, it's a so-called abundant number, the sum of its proper divisors is greater than the number itself (1 + 2 + 3 + 4 + 6 = 16). Well, it's abundant, highly abundant, superabundant, and highly composite. In short, it's a very versatile number lol Circle division, cock faces, calendars, etc., it's been around for a long time.

[@clehrich]

YES! This is why the Sumerians (or possibly the Babylonians) used sexagesimal (related to 60) numbers for all their horrendously complicated astrological calculations. If you do everything in sexagesimal numbers, you never end up with something unsolvable when, for example, you don't have algebra or zero.

@@TheGruntMeisterI own a porta-band also, and also consider it a dangerous tool to be used only when nothing else will do the job. I literally haven't used it in several years now. The horizontal band saw, however, is one of the safest, most versatile, and most used machines I own.

[@sundaynightdrunk]

@@edbennett8257 Agreed. I used to cut heavy steel angle iron and box iron on one and I did it so long I learned everything about the machine. It's very easy to get into a routine where your hands are never anywhere near the moving blade. It had a vise mounted in the bed, so you'd clamp your piece and never turn it on until lowering the blade. Very useful tool.

[@watahyahknow]

think he has a portaband , think i saw it in the background on the intro video of his mecanica hacksaw that said trying to cut through a round object on a bandsaw is not eazy as the piece wants to roll along with the direction of the sawblade and that can cause it to bind up or at least jump away from the saw verry unexpentingly , it can be cone if you clamp it intoo sumting with a wide flat base , but that that works in the mecanical hacksaw too

I used to work on a large estate and we had a workshop that was in the former wine cellar vault, complete with a large heavy vault door. We always keep it open but... One day it shut and was locked and an irate and unstable staff member took a sledge hammer to the combination dial. (Yes, they are designed clearly to prevent getting through that way!} Luckily only a week before i was curious about how the mechanism worked and took it apart to study it. When we realized the door was permanently damaged we had the guy from the auto shop bring a torch over and cut a hole at just the right place so i could fit my hand in to access the mechanism and work it backwards and blind and finally get it opened! Great puzzle challenge that was!

[@andyvan5692]

one tip, Adam, the likely reason for 24 pins, is that only 12 are used 'routinely', aka the 'lock', the others go to a glass plate, ie: insert the new film "the Italian job"- with mark Walberg as the main, and Charlie Theron as the 'locksmith' and the "glass re-locker" principle, if tampered with these weld it shut, thwarting any cracking attempt. The logic is simple, you can only see one gear; I surmise that there are two rings, co-axially mounted on that ring, one for this re-locker, the other for the main set.

They had to go to the Brownsville Ship Cannel and rent burning bar equipment to take the walls down - he said he would never take another bank demo. Speaking of the Brownsville Ship Chanel - Adam you'll enjoy this. That's where the USS Hope hospital ship was demolished... The USS Hope was the only ship ever built that had a standard 120 / 240 / 480 volt generator. Mr. Smith of EFI Furniture in Austin, Texas bought that generator / boiler and fueled it with the wood scrap they produced in the manufacturing process. He was able to power the entire operation and sell the excess to APS - all with scraps they would have burned anyway...

Don't worry. I'm a Mechanical Engineer and have had several gear classes and I've never heard of "modulus". Root diameter, Pressure Angle, Pitch are all good. Loved this video!

I was able to see the inside of a round vault door, and the gears interacting with each other was just a joy to watch. I wish it had happened more recently, so I could take pictures, but it was long before the cell phone.

Adam I gotta say man I’m so envious of your shop. The amount of projects I could do… man. I don’t know how often I’d leave.

[@BLACKOPS1499]

I really love ho enthusiastic you are about your work Adam! Never change, you are incredible! God bless you brotha! Also, just wanna say, you're incredibly smart. The stuff you make is really incredible!

[@Leafyfpv]

I totally understand how there is 20 years worth of inspiration behind this piece... Awesome mechanism.

I've only walked through two vault doors in my lifetime. One was at our local bank, the other was much cooler. I took a tour, when they still did them, at the Greenbrier Resort in my homestate of West Virginia. In case you didn't know, it was a cold war bunker that would house congress in case of an attack. We did a full tour of the "Oval Office" and everything. The coolest part to me was the vault door and their way of concealing it. We walked through a 20 ton blast door and didn't even know it! It was made by Mosler Safe Company.

Adam, we wouldnt compain if you built a full vault door, with a lock so as you can open and close it, a hinge, a "wall to set it into", you know the full shabang!! Would be really cool!

[@thomaswells]

i love watching someone do somthing they love to do

[@starhawke380]

Gorgeous work! I feel your pleasure about the amount of time and effort into making an item like that, and seeing it fit perfectly into the space it was designed for. Congrats!

[@stephenappleton117]

Watching Adam make, makes me happy

[@howa08]

Savage, you the man. Also Huge props for nailing that gear fitting on the first try.

[@macaronibones105]

That's cool! I love that feeling of, "Aaaaannnd...It works!"

[@Jackson87RandomClips]

Your enthusiasm as you build is infectious! Also, thank you so much for putting this kind of content into the world. ✌️

[@rickfazzini22]

You could even turn some custom bolts for the 12T gears cam style so you can dial in the backlash perfectly. No matter what you do I’m sure it’ll be cool! Thanks for sharing Adam you’re the best!

Friends of my dad live in an old post office, which also functioned as a regional branch of the local bank. There's a small vault room in the house, and even though it's well over a hundred years old, it's not going anywhere. Contractors have informed them that it'll be near impossible to remove, so they've made peace with it. Now it's their pantry.

[@micahbell3119]

Adam, you sir. Are amazing.

[@westbrookdrew7268]

I totally understand the appeal of the ASMR gear mesh action. Well done sir.
