Adam Savage's One Day Builds: Hellboy Samaritan Prop Barrel Rifling!
HTML-код
- Опубликовано: 8 окт 2024
- Adam has one final machining task to complete on his Hellboy Samaritan prop, and that's adding the interior rifling details of the replica's massive barrel. To accomplish that, Adam uses a custom tool called a broach, which needs to get precisely pushed through the barrel with a tremendous amount of force to make its cut. Adam has an idea of how to achieve that, and it's going to require quite a bit of elbow grease!

Drill Bit: "Look at me, look at me... I am the roll pin now"
Kurt vise: "Look at me, look at me... I am the hydraulic press now"
Next week: Adam takes delivery of a new 20 ton hydraulic press, and the FedEx guy gets a restraining order.
Hahahah
Or Adam finds a bottle jack in the trunk of a car.
20 tons might be about right. My "back of the envelope" calculation:
3/8 inch bolt diameter = about 1.18 inch circumference
1.18 inch x 18 thread pitch = about 21x mechanical advantage
about 5 inch grip handle / 3/16 inch bolt radius = about 26x mechanical advantage
about 70 lb x 21 x 26 = about 38,000 lb = 19 tons of tension on that poor bolt
(if indeed Adam was applying 70 lb using both arms, as he estimated)
I'm not going to claim this estimate has more than 1 digit of precision, but anything in that neighborhood makes it unsurprising to me that the bolt snapped.
@@rogerrabt Was my thought all along. I've seen my uncle pull out his old bottle jacks for a quick press job many times over.
@@_Nanigashi I suspect a lot of that was simply overcoming friction. Fastenall lists their steel allthread as having 60000 psi tensile strength, which using the minor diameter of 0.3005 in results in a maximum tensile load of 2.1 tons (and I'm sure the stress concentrations in the thread make it lower than that).
Home Depot lists Superstrut 3/8" allthread as having a maximum load of 1900 lb, which works out about right if you assume they're using a safety factor of two.
Of course all we know is that 2 tons was not enough force to finish the job, though I doubt he was applying much more than that with the vice. (And more press never hurt! At least as long as you mind your limbs!)
Adam, just imagine if that was a steel barrel and not aluminum.
What I'm impressed with most though, is the quality of that broach. That thing is a jewel.
I am sure they would do that before heat treating the steel I am curious how much more force it would take
"Chasing the zeros" he says, while using the precision machine vice as an arbour press :O
HAHAHAHAHA
I sent this video to a gunsmith I know, he replied that he started day drinking about halfway through this, then asked: "how does he not have an arbor press in that shop?"
Or even a cheapie harbor freight 20 ton shop press
Discovery doesn’t pay much apparently
With the effort put into this he probably could have built an arbour press assuming he bought the gears.
He’s too close to the problem and didn’t cheat and look up the answer. We all got to learn how the first gunsmiths figured out how to do this.
😂😂😂😂
Adam! I've been a fan of yours for many years, also being a machinist and welder from the Oklahoma oil field. I'd like to thank you for the 5 lb I lost watching you rifle that barrel, and screaming at my phone. I have to say it was more intense then watching a good mystery movie, you had me on the edge of my seat the whole time. Thank you so much Adam for all your hard work.LMA 🤣
I was yelling at him to take the drill off the fastest setting!
Haha I'm also a machinist and this really stressed me out!!
I'm only a hobbyist, and it still stressed me out.
I live in Oklahoma as well and my last job was in a machine shop for natural gas compressors... small world
Hydraulic Press Channel is laughing at Adam’s struggle.
There’s a collab I’d love to see.
Heck I'm laughing at it and I have a simple harbor freight one.
I'm only about a third of the way through this right now and he's doing all this work that you don't need to do...
Aaaand here wë gö!
This Savage is very dangerous, and we must deal with it.
i was thinking what about a longer bar for the leverage? oh Adam
That heart-sinking feeling when you're turning a thread and it suddenly becomes much easier to turn for no apparent reason.. ...before it suddenly lets go altogether.
* plink *
Like playdoh or modelling clay snapping.
@@njones420
In my experience it's more of a bang. It's also usually a 3/4" ACME thread.
When righty tighty suddenly becomes righty loosey
When righty tighty becomes righty loosy, lol.
As domeone studying engineering and also someone incredibly drunk you get an incredible appreciation for Adams intuition about practically everything
This is like the advanced version of removing a screw with a butter knife.
Who hasn't used a butter knife for a screw driver it use to drive my mom crazy
@@jackraintree4351 what he means is this is the advanced version of using the wrong tool, and having it work horribly but continuing to use the wrong tools.
It's like Adam Savage forgot that hydraulic presses exist.
or he never asked the guy who made the broach how to use a broach
i got to the part where he was saying pulling would be a better solution and came straight to the comments. glad to see the consensus on this one.
@@859awesomeness My first thought was "how are you going to pull with a press?"
Hahahaha
Dang, your friend put a lot of effort into that broach. You owe him a beer.
What if he doesn’t drink beer?
@@sambenao7 Then I suppose he could admire it.
Sambeano107 send him beer tokens
I guess you could say... he was a good samaritan
I'll see myself out
After the torture Adam inflicted on a bespoke hand machined tool he should gift at a minimum a dozen cases of beer or a couple of bottles of fine whiskey.
Adam.... It was great getting to join you through this battle of forces. I was on the edge of my seat so many times! This raw format really is relatable content for anyone who has stared at the pile of nice and shiny new parts wondering how the heck to keep them that way through past all the rip your hair out moments and to the final result. Bravo! You are a mad genius!
This sets a new record for "doing something simple in the most difficult Rube Goldberg way possible."
Maybe he doesn't have access to a press but kudos,mission accomplished
At that point of the project he really did not want to ruin it. Imagine the tool getting stuck mid way...
NOT AN EASY PROCESS... I’m surprised that the all thread lasted as long as it did.
I have been on a factory tour of the Bartlein Barrel mfg where my rifle barrel was made.... it’s a serious process... in the business.... it’s know as “Pulling the Button”
@@dcorbett1976 maybe not a press, but surely he's got a bottle jack somewhere
my father still has him beat
Adam 30 hours in: "Ok, I've secured the broach to the tip of an arrow. I intend to fire it down the barrel."
"So now I just need to build the bow. I know it'll be held together with 22-gauge pin nails, but I still haven't decided whether to make it out of balsa wood or tungsten."
That just made me laugh way, WAY too hard 😂
I laughed way too hard on that one. 😂😂😂
3 weeks later: "So the Russians came through and I have the plutonium. The nuke should ablate the heat shield fast enough to produce enough thrust force to drive the broach another inch or two. After that, I'm going to have to start looking for a tritium seller"
@@Sam_596 Why use cryogenic or gaseous tritium when you could use solid lithium deuteride? The Yankees had it right in the 50s.
I absolutely loved watching you explain for ten minutes why you needed to pull it through rather than pushing and then push it anyway. Lol
On today’s one day build Adam makes himself a hernia
holy fuck im dying
It's like he's never heard of levers.
@@slonismo He will too soon.
@@maxximumb I have almost never used power tool and I know to use a lever.
Anyone know if the aluminum bullet got stuck in the aluminum barrel?
I know one thing about rifling: they use a continuous flow of cutting fluid while cutting. Lots of lube would have made this allot easier.
There's always time for lubricant!
@@flying0graysons How do you know that? You don't know anything!
This is one of the most satisfying videos in the project. In the first video when the barrel was drilled out I kept thinking, :But what about the riffling?" So glad you went to that extra step!
Seeing Adam use an expensive kurt vise as anyone at home would use a harbor freight bench vise is a pleasure to witness. One of us! One of us! One of us!
So painful to watch.....
@@joellalashius7304 yes I totally agree... Using an at least $3000 precision vise for this job made my facepalm wake my neighbors and the closest one is a mile away...
here are 17 internet points for correctly spelling "vise". thank you
@@BerzerkaDurk oooooooo mmmmmmoo. 8
@@BerzerkaDurk *vice
Cool! Now you can make one of those glowing green tracker bullets from the first movie that lit up the barrel, it would allow you to show of the rifling.
OOH that would be cool! Also fairly easy to do. He has acrylic bullets already, just put in an LED with a button battery and switch in the casing.
I love that he did this by hand, without using a pipe for an extension to get better leverage, where as most barrel rifling is done with a lathe. Most don't have the patience to do this kind of work by hand.
Or the time
I wouldn't say lathe turning is a very common rifling method. Rifling is generally cut (single point or all grooves at once), forged with a mandrel (hot or cold), or pressed with a rifling button. There are also some less common methods, like electrochemical machining, which has recently become a rather practical way to DIY a rifled barrel.
@@Tunkkis Yeah, score one for the ECM. Super easy.
When you said that you were going to use a drill to pull the broach through I thought to myself, what kind of nuclear powered drill does he have?!
Today on One Day Builds Adam triggers, machineist nerds, Vice nerds, gunsmith nuerds, and physics nerds all at the same time, stay tuned to find out how.
Mate I'm none of those and he triggered me no end.
Why did he not use a hydraulic press? Why did he not use mechanical advantages like a "cheater pipe" for more leverage on the vice? I have many more questions...
I winces
This made me audibly laugh
@@BraveNewWorld-1984 Because it would have snapped the all-thread rod even faster than he already did.
He used the wrong type of all-thread, it looks like he had the generic galvanized stuff designed for low loads. He needed grade 8 all-thread, which is harder to find, but it won't shear off under the kinds of loads he was exerting on the rod.
Adam, watching you push that cylinder towards the band saw blade was terrifying.
Love the build. You continue to be an inspiration.
Despite the fact that having a press would have made things way more efficient, i like watching Adam improvise a method to circumvent the lack of one.
Be sure you do the opposite.
I feel like this sentence is incomplete...
@@ProjektKlover Indeed! It was, i will correct it in a sec.
I get he doesn't have a press, but i'm genuinely amazed he never thought to just use a bottle jack
And ruin several things in the process.
I am actually surprised you don't have a press in your shop, even a small one. Heck, a Harbor Freight made one would do the job you need for this prop.
I thought this too. 🤓
I think the simple elegance of a Dake arbor press would fit Adam's personality better than a Harbor Freight press. However, a HF press would have done the job in no time.
Sitting here thinking the same. My horror fright press would have made this one hour job into a 20 minute one. Once I picked one up I find I use it all the time now. Swapped it out to air over hydro so it's nice and loud but tons faster and easier.
Isn’t a bench press the same thing? Adam looks swole enough to do it himself
I have a little HF arbor press. It would have rocked this.
That was some of the most riveting television I have ever seen. An emotional rollercoaster.
I will never not smile when Adam uses his tattoo ruler.
Its gonna be funny when one day his build doesn't work and he's realised his tattoo ruler has stretched or contracted 😂
@@llamaczech my thoughts exactly. Specially when tattoo lines have thickened over time
I just watched an hour long video of a man putting a round peg through a round hole
so true, can't stop laughing
It’s fun knowing that you have the answer and Adam does 40 years of rifling development in front of you while brute force solving a problem that isn’t that hard if you looked at the teacher’s notes.
Ha, ha, ha, ha, ha! That was as true as it gets! 🤣
without proper use of lubrication also
I've been in two shops that did rifling full time. Hydraulics are used. I am actually suprised you didn't employ a pneumatic impact driver on your all thread though. Neat project!
I wasted a full hour just to yell the exact same thins at my screen
Adam: To those of you yelling solutions to these problems at the screen...
Me: *stares at my husband*
Husband: Whaaaaat? He can’t hear me!
Me: Clearly he can. He just addressed you.
😂😂😂
i hear what youre saying. and i can fix that.
"You have to be able to visualize the forces involved..." and then proceeds to use what looks like aluminum all thread and a cordless drill.
Guarantee that wasn't aluminum all-thread, for two reasons: 1) it would have pulled in half long before it did, it doesn't have the tensile strength. 2) He ground it and you can tell from the sparks, aluminum doesn't make sparks.
this was my first thought lol, watching this extensive process of building out this whole thing to suddenly start using a cordless drill and seeing it all go wonky and seemingly not straight
Had me on the edge of my chair, all the way! Thank you Adam!
Not aluminum all thread but it looks like galvanized or coated thread from like Atwood's or home Depot. The color and yellow on the end reminds me of their little racks full of "metal"
Not aluminum but twisting it was a mistake from the beginning. Using a nut to twist and pull that rod would save him a lot of work and time.
That was a good first idea to pull through but I saw that shear coming. I am impressed how deep it got better it failed! Great outside the box thinking as usual!

Well placed quote!
Also, watching this video I'm reminded of "there are hardly any excesses of the most crazed psychopath that cannot easily be duplicated by a normal kindly family man who just comes in to work every day and has a job to do."
But that wasn't the problem.
@@txm100 it was the problem he didnt have the right tools for the job. a press wouldve made this an easy 20 min job
I could hear my car mechanic Dad shouting “More leverage!” in the my head for this whole video
I was screaming " GET A JACK HANDLE, DUDE"
Leverage is king 🤣
Probably already mentioned, but the big advance with the Minie ball was that it was actually SMALLER than the bore of the weapon. Previous to it, jamming a musket ball down a rifled barrel was difficult because it had to be the same size as the barrel to engage the rifling. It took far more time than loading a smooth bore. Rifles were used in earlier wars, but by specialized troops. Even with a musket ball, the spin imparted made them far more accurate. With the Minie ball (which was bullet shaped, not a ball), when it was fired, the base, which was hollowed out, actually expanded to engage the rifling. So easy to load, and still had the advantages of spin imparted by rifling. And deadly. Huge bullet with lots of mass would shatter anything it hit.
For a quick force estimate:
The ideal (frictionless) mechanical advantage of a screw is the input distance for 1 rotation (2*pi*r, where r is the distance of the force applied to the center of rotation) divided by the output distance of 1 rotation (the pitch of the screw). Assuming your hands are 5" from the center and the all-thread is 3/8" UNC with 16 threads per inch, MA = 2*pi*5" / (1/16") = 502.6. For every pound of input force with no friction involved, you apply 502.6 lbf axially.
In reality, there is a large amount of friction associated with turning a screw (as I'm sure you're aware), and even well-lubricated screws have efficiencies ranging from 15-20% of the ideal case. Taking the low end of this means that an estimated real mechanical advantage would be something like 0.15 * 502.6 = 75.4. With ~60 lbf of input force, this means that the axial force you apply on the barrel is in the ballpark of 60 lbf * 75.4 = ~4,500 lbf.

If we know how far the cutter had to travel and hand wave away most of the losses with some assumptions, we should be able to tell how much energy he put into this and therefore how many pop tarts are needed to rifle that barrel
I just want to say, I love all thread. Learning that I could buy threaded rod by the foot was life changing.
Give me some all thread, nuts and washers and I'll either move the world, or fix it in place. Dealer's choice.
"I have a friend that will make me a super high quality custom rifling broach, but somehow don't have a friend that would let me borrow their press for 15 minutes"
I heartily recommend a look into the Whitworth rifle, And the history of Whitworth (same guy who developed the Whitworth threadforms, and worked out the "three plate method") and was one of the first to really understand what we now call precision. Fabulous British inventor.
Smarter Every Day did a great video about it.
also if you look up the list of "longest range sniper kills" on wikipedia one of the top 10 or top 15 or something is still with a blackpowder Whitworth in one of the clear cases of "YOU CANT DO THAT HANDS OF MY PHYSICS I NEED THOSE TO LIVE"
Sir Joseph Whitworth was an incredible inventor and also a philanthropist and bequeathed a lot of his wealth to the city of Manchester. I was lucky to get married in the house he built in South Manchester when the University of Manchester still made it available for such events. Its amazing people can still get an engineering degree scholarship under the original scheme he set up.
@@craigwelsh wow, did not know that about his philanthropy! Wow how we could do with some more like that these days.
So, a real life genius, weapons inventor, philanthropist, (playboy?). The original Tony Stark?
Personally, his contribution to standardisation and precision manufacture is, or at least was, the thing that impressed me most about Whitford, but perhaps permitting others less fortunate to learn is just as impressive.
Near me, there's a school for adults called the Thomas Wall Centre, Thomas Wall of Walls sausages and ice cream etc, and he too made a bequest for education which still exists to this day. He used to live locally.
Thanks for the tip about that. Am going to do some more reading.
ruclips.net/video/T-xMCFOwllE/видео.html Whitford was an amazing man, in so many ways.
@@JWbrasser Black powder is bulky, explosive, and dirty . . . but has velocity deviation of about 10% of modern smokeless powder. You see smokeless standard deviations around 20-30 FPS with a .45-70 (or 90 or 120). Black power is 2-4 FPS. It's amazing for one round high accuracy long-range shots. Yes, I do want to put 500 grains of lead on a gong 2 miles out. (I can't, but I'd like to)
Is anyone else shouting at the screen “put a pipe on it!!!”. Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.
I want to send him a breaker bar for Christmas.
That would have just sheared off the allthread sooner.
@@tomhorsley6566 not when it was in the vice it would have given him more leverage.
@@tomhorsley6566 I'm thinking more for the vise handle.
The poor vise has already had extensive misuse, why would you want to break it already ?
The amount of work Adam goes to to add rifling to a barrel that will literally never fire a single round is both inspiring and concerning!
For Sale:
Good as new Kurt Vise.
Only used once!
IM LAUGHING SO HARD FL_HEISBSHIAHRIDHFNDBFD
At this point i believe if Adam had a hydraulic press, he would have used it to turn the lever of his new Kurt Vise :.(
why the press can be driven and a sledgehammer to do
😂😂😂😂 i was thinking that
Then he can see how many tons of force it takes
Dake arbor press....All of the force, none of the remorse.
@@mattystewart8 aaà
FYI: Using a "breaker-bar" pipe extension on the vice grip handles would have helped with the torque! Nice job Adam!
This is exactly how Smith & Wesson rifles all their barrels..
doesnt the industry use rifling buttons or automated machine brooches (think precihole)?
@@angrydragonslayer Depends on the company. Some forge their barrels around a rifled die form, really useful for progressive rifling like the Carcano rifles.
@@angrydragonslayer Depends some use Cold Hammer Forged.

I laughed loud enough for someone to check on me.
I'm not sure I could do the job stoned. You do it and make this video! Good job.
What a rollercoaster ride! It's good to see that even Adam bodges it with the wrong tools sometimes 😅
This was gripping. Literally. Laterally. Longitudinally.
I just sat here watching Adam turn all thread using two vice grips down a aluminum tube for 35 minutes. I feel great!
This is the most nerve-wracking video I've watched on RUclips... and I still have 30 minutes left to go!
You're at the point where he stops using his homemade allthread screw press solution and is about to take his brand new precision vise and use all of his body weight to treat it as a primitive screw press...
A vice that costs about the same price as three cheap shop hydraulic presses.
@@TravisFabel Pure mental agony, there! I had to pause the video and check the comments as a break.
@@lagweezle The comment section is what brings me back to normal after watching this :D
Ya know, you could have just drilled the top block without threads and just tightened a bolt down against it, pulling the thread up through a bolt, and no vice grips needed. Just a wrench.
Seriously! That’s what I thought he was going to do!
When he started tapping that block, I was practically yelling, “Why the hell are you doing that?”
A nut is made to be turned. All-thread is not.
Thank you!
Just a large washer, a nut, and a long wrench and plenty of cutting oil and he would have slowly pulled it right through.
I truly do not understand his thinking sometimes.
I don't know if the tensile strength of the rod would have still been enough to pull it through. It would have eliminated a major source of torsion, however if the nut at the bottom of broach still spun when it failed, torsion wasn't a factor. All the torsion would have been at the top of the rod between the vice grips and the block, but that's not where it failed. Even if it was drilled through, the rod has to rotate for it to matter. He most likely still needed a stronger rod.
@@ryanmcgowan3061 a coupling nut welded on the end, and a tapped block on top about hand width high with 'arms' to slide a pipe over as a removable handle possibly would have worked. I know all-thread isn't the strongest stuff but I think it would hold up with that amount of thread engagement. I would have made jig with welded square tube & a bottle jack to push it.(with a bonus of then having a small press for future uses)
Also stainless steel all thread would not have sheared so easily
You know what I love most about his builds? The cooler the build, the more giddy he gets the closer he gets to completion... I wish I got that level of excitement from my work.
👍
You should look up the machines they used to use during the Civil War Era to rifle their barrels... it's not too far off from your solution, actually.
And btw, next time, if you're only doing a cosmetic rifling... learn to use the worm gear on your lathe... or your cnc commands.
I've never had so much anxiety watching one of your vids..... usually they're very calming. That, good sir, was not.
All i say: A Carjack, a few pieces of wood and a wall. Done. It is Aluminum after all :)
I saw Title and thumbnail and had no idea how he filled the runtime with a simple broach and thought it was realtime maybe. Now i know^^
Dude owns a Hi-Lift Jack mounted to his truck two blocks away. It has a top winch-clamp-spreader that's good for 5,000 lbs. It could have easily been used as a press rather than those poor vices. "He needs to use a press" was the first thing I said when I saw his setup. I also said, "That all-thread will fail."
@@bradstapleton2041 Yeah. I can´t believe he did ALL THAT WORK and instead of just countering 2 Nuts and using a wrench at the very least....he actually tried it with two vise-pliers? :D
I’m a stationary engineer which is kind of a jack of all trades with specialties I wanna mail life and I’m in electronics engineer however use a hydraulic press go to Harbor freight get a bottle jack little hydraulic jacks most of them will work upside down but not all build you a frame with a nice steady base and just pump the jack and let it push it right down through the barrel When you get to the end use a smaller rod and push it the rest of the way right out the barrel works every time it’s how we key a sprocket with a brooch adding shims to each pass until you get the full depth of the key that’s the square hole inside of a sprocket. I hope this is helpful my friend I have admire you greatly...But the way you did do it was genius love your stuff man
This is hands down the most stressful video I've ever seen on Tested
Ditto. It instilled in me the same feeling as driving past a freeway accident. I want to look away, I know I SHOULD avert my eyes, but... To be honest, this may be the first time I've watched a tested video and felt dumber for it.
This is the most stress testing Ive ever seen on a Kurt vise.
it was this video that made me understand how sports fans feel when their favourite team makes a really bad play. I had to pause & take a 10min breather when he tossed it in the Kurt :\
This stressed me out watching Adam yet again insist on doing everything in the most difficult way possible 😱
If Adam's shop existed in the Toy Story universe:
Kurt Vice "This is not the job I signed up for!"
Every other tool in the shop:
"Welcome to our world!"
Thanks for being such a big part of my childhood.
my mind is screaming "practice piece"
A good job his workpiece wasn't proper.steel and not just a soft material like aluminium.
Did anyone call the police on you for what you did to that poor vise?
Let´s potentially damage this nice expensive vice instead of buying a cheap press.. :(
@@SuperMarioLecter There's nothing "potential" about it. There is no way that didn't cause large gouging. On either vice.
@@anonymousaccordionist3326 can you explain how please? The part with the Kurt vice? What exactly did he do wrong?
E: a few minutes have passed. I see he removed the plate on the vice x.x I understand now lol
@@nickjames9386 The real issue is using it as a press in the first place. A vice is for holding an object in place. Using it as Adam did puts foreign stresses on it that can do some extreme damage in the worst of situations.
I see lift in that vises future. Doing that puts way to much force on the internal angled wedges that connect the screw to the moving jaw. My jaw was tense just watching that.
After watching how actual barrel manufacturers rifle barrels im surprised that broach spun as it was going through the barrel and didnt just cut straight grooves. Good job as usual!
that was thanks to the design of the cutters them selves. they literally had no choice.
This feels like a visual representation of passing a kidney stone
Oooh ouch!
You Killin me
Try a 3 inch pipe tap by hand...
ahah
Ugh don't, I never want to get kidney stones
Me: ooh, I'll just start this video and watch for a few minutes and go to bed. Me 45 minutes later: jesus fuck dude.
Right! Exactly what I was thinking.
🤣🤣🤣🤣🤣🤣
And now we know why Jamie was always frustrated with adam
The compressive force in the vice @ 120lb with an 8in handle = 80lbf torque and 7,342lbs compressive force (the Kurt website has a torque->compressive force chart)
I don't think I've ever had a reason to yell "hydraulic press" before, but ... yeah. Even a harbor freight el crappo especial model would have done the job without much pain (or something like AvE's "little screwy" if you want to DIY it). Broaches and presses are best buddies. Also note, that bit of allthread is probably measurably longer than it was when you started - compressive force > tensile force, pretty much always.
Can't argue with the results though, it's quite beautiful.
Tension has the advantage of self aligning, and not worrying about buckling. But yeah things are often stronger in compression
@@LuvLikeTruck and those are the words i needed to communicate the benefit of pulling... self aligning. nice lay-engineering tip.
If only Adam could hear the ghosts of 10,000 machinists that were screaming over what he did to that new Kurt vise.
Yeah, I was totally speechless.
so theyre kinda fragile?
I literally screamed “arbor press!!!!!!!!!!” a hundred times during this video. This happens in our shop all the time. One fella finished the job in ten minutes and then sets and watches the other fellas engineer a never ending concept for doing the same job. Love it though.
45:04 "I wonder what that sound was?" I don't know but I just saw the part fly passed the camera.
I like how he keeps repeating "this is a totally reasonable way to [...]" as he comes up with increasingly convoluted and inefficient ways of doing things, just so he has an excuse to use yet _another_ tool. :D
You did it I’m proud of you you worked with the tools at hand and you solve the problem just incredible I was with you every second believe me
This is a good example of tunnel vision when doing a project
I had thoughts also.
Care to enlighten us with yours?
Exactly!!! A shop press and some grease could have gotten this done in 30 minutes 🤣
This could’ve also been solved by an old school Bridgeport series 1 in a few seconds, but realistically, cost of labour vs machine cost was way lower here.
100% We have all been there. Usually in hindsight it would have been better to take a step back and rethink the plan. XD
I'm thinking, why rotate the allthread?? Why not just put a nut on the pulling end and just tighten it?

Do not use your vice as a press.
@@Hitycooking Go spam somewhere else with your shity design please.
I know it's simple old tech, but I find the vise grip to be an amazing invention.

“This is brilliant maker forgets that hydraulic presses exist, in 3.....2.......1......”
Personally I would be worried that the hydraulic press would not allow the broach to spin properly and adding anything between the broach and top plate of the press would add the chance of the two piece to slip apart under significant force. Pressing a piece of vacuum hardened steel through a piece of aluminum would worry me enough because of the chance the steel might bite and terribly deform the aluminum in a half second.That and to make a rig to compensate for all that would probably take a long time and a person smarter than me because I have only really used my press 40-50 times in the last decade. I would have ended up making a stupider version of what Adam made but mine would have had the nut on the other side welded on.
@@arespirit maybe, I’m definitely no expert. but he basically used his vice as a press, only he had to use his own muscles.
@@BittyVids I think it comes down to the control he had using that vice and being the one to turn it. My hydraulic press can be scary to operate and moved deceptively fast when inflicting damage. In the past before I could lift my finger from the button it bent a hardened steel pin and had started to push its side into the other piece of material. A 50 ton press can do a lot of damage in a split second and men that operate the bigger ones are a lot braver than me.
@@arespirit the friction of two small flat surfaces pressing on each other is going to be significantly less than the force imparted by the angled cutters as they are pushed through the metal.
@@arespirit Stick a ball bearing between the broach and the ram. Not a raced bearing..just the ball, add a touch of grease and voila!! it will spin.
Adam: "you see where where its going!"
Me: no
Ha!
I hit that point and unfortunately saw where it was.
It seriously impressed with how wide a skill set Adam had. He might be a generalist, but he’s got the tools and skills to solve almost any maker’s problem.
I want to send this to my father the engineer out of hate and spite, because there are so few parts of this that won't make him cry...
You hate your father it take it?
@@rprichard8452 I mean, I'm not NOT saying that...
Do it. Record it. Tag adam
I'm genuinely impressed that this actually worked and din't completely scrap the part
This was just as fun as it was painful to watch. I appreciate that you show the whole process and don’t edit out the painful bits. Its somehow comforting to know that you also do trial and error every single step of the way - just like the rest of us. That being said: You could’ve just used ball bearings and a tube (I’ve seen good examples of people salvaging from the pedals of a bicycle for example) from most circular systems to keep the spinning rate fixed while not forcing the broach to over-spin instead of using Teflon which expands and sticks when exposed to heat and friction - then just made an Aluminium frame to account for the “force problem” which I think you overthought. I mean: clearly you have hydraulics in the shop so you’d be better off just using that. But if you wanted to use common folk tools, which it seems like you do, then fret not.
Then for the barrel itself - housing it inside a tube that has the twist rate marked on the outside and then traced by tapping down a soft rod to make a helix-like guide rod around the outer cylinder thats housing the barrel - then have said outer guide rod fit through a notch at of the end of that Aluminium frame: controlling the twist rate whilst the ball bearings prevent over-spinning.
This is the equivalent to walking around the entire creek instead of jumping over it by simply using a small hydraulic press.
I always jump over creeks using a hydraulic press.

Next time you need to rifle a barrel Adam
Just give me a 24/7 live stream of you in your shop through an IV straight into my arm. Maybe two IVs. I don't need sleep, I need more Adam Savage.
FYI the clamp load was around 22,000 ft/lbs if you were applying 75ft/lbs of torque
A hydraulic press...longer throw, more torque and less pain.
Adam, you are growing into a Mr. Roger's type influence for new generations.
That is a GREAT thing.
It gives me genuine inspiration seeing someone like this drop as many things as I do...
"Im really going to enjoy the reward of a poptart after this"
- Adam Savage
This checks out. Specifically those of the strawberry variety.
I actually bought some pop tarts because I saw this comment 😅
Watching this was such hard work, I think I'll reward myself with one too 😂
I was scrolling through the comments while watching the video and arrived at this comment at the EXACT same time he said it...... what are the chances?! Craziness.
@@tested I am a Wood Worker so I am building a panel with this quote going up in my shop
Adam, a tip for threading a single nut all the way down a piece of threaded bar for you….
Put a nut and a locking nut at one end and tighten them together, grab your impact wrench or electric nut gun and put the outside nut into a socket, use the drill to twist the threaded bar while you hold onto the nut that youre trying to thread all the way down the bar. Takes literal seconds and its so much easier. Also saves damaging the bar by clamping something directly to it.
12 minutes into the video, I'm sort of wondering if the press and the jack have been _uninvented_ recently.
Sometimes I wonder if Adam even knows what he's doing...
@@bobthebrickbuilder1876 - I think he's mostly trying to come up with excuses to use / buy as many tools as possible.
And screwing things up means he then has an excuse to use _more_ tools to fix the mistakes, and _even more_ tools to disguise the ones he couldn't fix.
It's bad enough that he doesn't have an arbor press in that shop, but if he would have thought about it for half a second he should have realized he already had a tool that would do the job just fine. Quickly build a proper mandrel on the lathe, use his clamping kits that he showed us in another video, clamp the barrel on the lathes carriage where the tool post is, then with the mandrel in the headstock just turn on the feed so the carriage is traveling away from the headstock. In the end it would have taken less time and with fewer hernias.
Saw that shear coming, just waited for it.
You, me, and many others, too. Waiting for the "click" when the all-thread breaks.
I was surprised it sheared, I was expecting it to strip the threads.
I have no idea if it would have worked but in the electrical industry, we use a hydraulic knockout punch to cut big 4" holes and larger holes in steel boxes using pure direct sheer force. I imagine if you crafted your own very long center rod for one of these you could make it work perfectly fine for this. As a benefit, you can get them fairly cheap and they are a self-contained manually operating system so you don't need to build a big hydraulic system. The one we use which is more expensive than most but a professional tool is the Greenlee 7506.
I love this, this is amazing problem-creating countered by incredible problem-solving.
That was like watching an over-caffeinated child put together a train set.
There has to be an impact wrench somewhere in the cave.
That's about what I saw too. I can see why he and Jamie are probably not working together now, Jamie would sit there with his arms crossed assessing the situation, all the while thinking this dude needs to take a chill pill.
LMFAOO!
@@thebiggianthead8364 even though the two of them don’t understand gun smithing between them they would have come up with the right solution almost immediately. It helps to have a second mind, even if they don’t know the answer either.
i knew as soon as you said you wanted to pull this broach through this barrel, that youd most likely resort to pushing it sooner or later. i thought you almost had it. but i figured when the 4th set of cutters entered bad thing would start to happen. i honestly would have probably set up a rig to press this broach through entirely, starting this operation by pulling was really good and had a ton of advantages. but after the start making sure its perfectly settled in its hole, i believe pressing was the best method
My throat is sore from yelling "use a hydraulic press..." lol
I still don’t understand how a press would create the spirals inside the barrel. Wouldn’t it just create straight line cuts?
@@K3v114 the broach creates its own spirals. He didn’t turn it the way he did it now either, he turned the all thread.
Waste of energy, since he clearly doesn't own one.
@@Khazandar He explained at the end that he simply underestimated the effort this would take. I think he would have bought a press specially for this task . Let’s just say he’s spent a lot more to save a lot less effort.
Petition for "That's a lot of force" merch.
Can the back of it say should have got a bigger lever
as a machinist for 30 years I found this video the hardest shit in the world to watch. Everything you could possibly do wrong you did!!!
Adam, I'm watching you turn that vice and screaming, "Increase your lever length!!"
FYI, kids: a 3-ft. steel tube slid over the end of the handle makes it much, much easier to turn.
O.O
The word you're looking for to describe the shape of the rifling would be "helical"
My exact words at 4:12...
Good God all mighty! What au show. " You really know how to redefine PTSD. You and the dam gun barrow forced me to relive every time a piece of metal "Went Snap!" I was glued to my chair, the whole time, with the F-word on stand by, but, you pulled that shit off with commanding authority. It's time to celebrate. "You are the man!"
10 minutes in: "I should have bought an Arbour Press..."
I was thinking the same thing, wouldn't that have been easier 🤔
I don't think one would have enough pressure.
