Adam Savage's One Day Builds: Spacesuit Negative Pressure Chamber!
ฝัง
- เผยแพร่เมื่อ 9 ก.พ. 2025
- While admiring the aesthetic fidelity of his new spacesuit glove replicas, Adam comes up with the idea to test its pressure seal by building a negative pressure chamber! Made from a thick-walled acrylic cylinder and custom-built glove mount, this glove box lets Adam simulate the experience of operating a spacesuit glove in a zero-pressure environment. It also makes for a striking display case!

adam savage i like a lot of your work/tv-shows/ ect but please be more careful about how and who you buy your tools from as im not saying that you broke into my shop or my dads shop but you are using stolen tools from us, noticed the marking's in the video
PS. for you adam and anyone else buying stolen goods or possessing hot goods knowingly or by accident is/can be jail time and up to a USA 🇺🇸 felilleny ect aka acompless to the crime at minimum
@@richardprice5978 which tools were they? Have you found them online being sold?
@@paulpomrehn4356 i know some ended up on the Internet and some local fence's ect. but for the most part my local PD ( i did have a couple of cops on the force willing but my understanding is they got steam-rolled by CO's so not as effective as i and others hoped for ) didn't what/interested to do anything about it or help stop future pre-1990's Classic-vehicle's grand auto/theft/crime.
as for video adam is using saw's and maybe clamps ( can't id things like the clamps as well as the saw as im not in the shop looking at it from first hand, and there's a good chance some of the tooling is clean/pass's a "car-fox" test just that one saw definitely got stolen at one point so it doesn't pass the tests ) with a "hot history " one was bought for my pine wood derby 10+ year's ago originally but dad did cabinets/construction 🔨and now is retired from it and tool's from 1920-ish to now walked-off 3-ish generations ( some from navy's/airforce veterans/WW1,WW2,korea,nam and where used in battle to repair equipment ect. so to me on a sentimental level there not really replaceable, on top of me being a mechanic 👨🔧so i need them for feeding my self/paycheques ) of family-tools i inherented, like i said as far as know adam made a honest mistake and doesn't know anything about the fence so im saying please be more careful and im glad he is more talented than me at using it and teaching others skills so it's not a jelly-C thing more of a please don't encourage fence's/crime and the one guy that 1/2-busted was need/hungry just did it for entertainment/side hustle/$$$ of others misery
You should install quieter arms for the camera.. or edit the squelching noise in post? Its very jarring lol 😮
Hey Adam. I'm one of the few people lucky enough to work with the EMU gloves and suit on a daily basis. I also work with the glove box you're trying to recreate. We use it when sizing gloves for new astronauts. If you have any questions about the inner workings of the gloves or the suit, I can help shed some light on anything you may not be able to find online. For example, we depress the glove box to a delta of 4.3 PSIG!
What a wonderful and helpful place the net can be at its best. Makes me happy to see you chime in, willing to share some knowledge with Adam. Hats off to good humans. 👊😉
Ever make it over to the SVMF?
@@originafreerangechicken Sometimes! Although we're based at the NBL. Depends where the suits are needed that day.
@@GrayishPlacebo Cool, I’ll see ya at the next pressurized activity over there, maybe. 😉
You may have just made a new best friend in Adam
Adam going from making space suit replicas to making actual pressure suits.
your next space talk is gonna be about nasa contracting adam to build their new space suits
Now here is a crossover from years ago watching Kerbal Space Program videos, that I did not expect to see.
@@SilentCastHD I love that game and those videos
May I just say that I love your ksp videos? They're awesome dude
Dude! Retrofit the chamber to be drawn down to 0 atm and have a ringing hammer and bell inside it. No sound will be made and it shows off the negative pressure part. Such a cool build!
Depending on how it was attached, the bell's vibrations could leak to the jar through its mechanical connection. There would be some some sound possible.
I think behind that thick of plexiglass, people would just assume it's very well sound proofed.
Could just hold a bicycle bell and ring it with 1 hand
@@sjdpfisvrj BUT, you could ring it with air in the chamber first for a point of reference, then keep ringing it as air is pulled out and observe the sound become quieter. For SCIENCE!! ;)
I'm gonna use that at the hospitals. That's an old shoulder and it can't do that anymore. Adam, still an inspiration everyday for this old, sick, beat up biomedical engineer. Love it brother
At the beginning of every video Adam always makes his first critical cut to a closer tolerance than I would ever go "15 is good...oh wait no 14...wait is it 13?" just freaks me out everytime
Same here lol. Brain was screaming "Stay at 14! ADAM Stay at 14!" Also, the way he cut the tube is pretty wild...
With it costing 400 dollars, I'd be trying to squeak out as much as possible lol.
Yeah and without seeing how much room for the pressure connections and room to move his fingers first!
I love how Tested videos accumulate so many talented and experienced engineers and fabricators. The think-tank that this community would build is impressive.
This is fantastic! Some suggestions: there are multiple air leak paths with your gasket design: between the neoprene glove and the acrylic, through the screw holes in the neoprene glove, and through the screw holes in the acrylic. You could minimize most of these by mounting the neoprene glove to the *outside* of the chamber, so your layers from outside to inside are: delrin washer, neoprene glove, rubber gasket, acrylic endcap, rubber gasket, fabric glove, delrin washer. You could do even better by using two different sets of blind tapped holes, one to hold the fabric glove, one for the neoprene, so there's zero path for air to pass through the acrylic. But blind tapping 24 holes in acrylic would be no fun.
But of course you can't do any of this because the bottom cap is now permanently glued to the tube. If you wanted to take another crack at this, it might be worth cutting off the end cap, gluing an acrylic flange around the outside of the tube and attaching the end-cap with removable bolts and a gasket. Adds another possible leak path, but makes debugging so much easier.
Could always cut two crescents of acrylic, blind tap, and glue them to the inside, and then glue up the seam.
My bet is an air leak between the acrylic parts Maybe it can be sealed with some kind of rubber seal around the edges?
I'd put it under positive pressure, and then run a little soapy-water around the joins to find the leak... The old bicycle-tyre trick.
IMO, the real flaw in the design was that he gave himself very little ways of debugging the leaks. For example, I don't think he really needed to glue both ends, I think an O ring on the top end would have sufficed since the pressure would have held it in place.
@Erick Girouard yup! I second that, unless you are going into (low) high or ultra high vacuum territory (and that is a whole other story) orings are perfectly fine.
I would totally watch a video of Adam experiencing the NASA pool suit training.
Not an easy thing to film, which is why I expect it wasn't done commercially yet (Mythbusters, etc.).
You know, I have *so* much respect for your ability that seeing you make small mistakes, or seeing a build not work out entirely the way you planned, is incredibly heartening. "If Adam Savage has these problems, maybe it's okay that I do too."
Amazing how Adam has worked in this industry for decades and never worn masks. How he is not riddled with cancer is astonishing.
Probably same way some people smoke for 50 years and live till they're nearly 90 it's just your luck i guess
I'm 58 and used to change brake shoes/pads that were made with asbestos... And we used to blow the drums out with compressed air too!! Never had breathing problems, no lung cancer, nothing... And I smoked for 20 years to boot!!! As the other fella said, just dumb luck I guess ;-)
@@n7565jyoure gonna jinx it
Breathing resin fumes seals and protects the alveoli in the lungs from the particles produced by sanding toxic materials!
Camera man never dies😂
Watching adam work while I craft is so zen that It's become my habit to watch a tested video and craft at the same time.
This channel is awesome but watching the cosplays he makes is worth it
I find it strangely hypnotic and therapeutic watching Adam word. Thank you for releasing the tension.
Oh yes, my good man. My son is in southern Nigeria. I needed this.
this is like the whole watching your dad work on the car but none of the hold the flashlight to it. lol. My son and I are also Astro-nuts he's currently taking college courses in high school so he can be an astronomer. I'm so proud of him. He loves to watch this type of stuff. this has a lot of the same feeling as the 'in space no-one can hear you fart' rig from mythbusters Jr.. thank you for everything you do.
Feel like your the kid ......
Always love a flat board with plywood glued to it. Very useful.
Funny as hell. I caught that too.
Yip…. Caught it too….😂😂
Adam I work for a utility company and the linemen always check their rubber gloves for holes, even a pinhole could be fatal, so you may have a tiny pinhole in the glove.
yeah, remember how he was really stressing it on early in the vid right? it could easily have a pinhole. Good call. It's been 4 months since he shot this vid lol, he prob already fix this or made more.
I’m pretty sure I recognize the brand of glove he used. It’s some off-brand cheap “heavy duty” natural rubber glove. Something you might find in a dollar store hardware section. Wouldn’t be surprised if it had small manufacturing defects. Adam should have used the nitrile glove, or a butyl both of which have lower air permeability.
Hey Adam. Tightening seals in a star pattern helps ensure a flushed mating surface. Hence a great seal. Love this build. Very informative. Thank you.
That’s also how you tighten the lug nuts on a car wheel, which he should know. Anytime I’m tightening down fasteners that should be parallel I use the star pattern method.
@@falconwind00 along with any kind of seal. Valve cover, transmission pan, oil pan., all the fun stuff. Cheers to you my friend.
I love the shots that are taken from mounting the camera on the milling platform, so the background moves back and forth, like at 33:40.
The last video I watched from you was the "Favorite Tools: Awesome Circle Drawing Tools" (via the Makers Cabinet pencil holder). So I was amused to watch you use exclusively tape rolls for your circles on this build :)
I'll bet the gasket on the inside might be the culprit. Very cool Build and it always feels nice to display cool things you like.
Living my own world of ADHD is surely what has formed my love for you Adam, you were always my favorite on mythbusters and nothing has changed.
I feel the same way!!💯🥰
I showed this to my cousin who works at JPL and he was blown away by how awesome this was! He said they are basically all makers there at JPL too!
This was great! If I may suggest 2 things: I think this way the vacuum is working against you around the rubber seal. I would mount the whole glove assembly from the outside so the vacuum can pull the rings and seal together. Next to this if you would make a non permanent joint for the bottom plate (with the glove mounted) than there would be a much easier access for testing the different glove adjustments (kind of like a coffee storage can). Thanks for the great content, enjoyed every minute. May the vacuum be with you!!!🙂
You could have cut and drilled those precision parts with a CNC mill, but watching a master of machining do it by hand with a variety of tools is so much more fascinating and satisfying!
Querido Adams amo tu trabajo porfabor nunca dejes de hacer estos maravillosos videos no te dejes llevar por los malos comentarios tu no eres como ellos y ellos no tienen lo que tu tienes ... eres auténtico y brillante sigue Adelante revolucionando el Mundo Adams
Adam surprises cashier with who he is. Adam makes cashiers day by mentioning the cashier in the video in passing. Cashier will have one hell of a story to tell in the future.
Fascinating build Adam. Encouraging you to do round two on the build. With some guest makers to help.
EPDM gasket, Neoprene chemical gloves utilize a canvas substrate. The EPDM gasket under negative pressure
on the cylinder will hold very strong without a mechanical bond. No cement necessary. Awesome build!
How to make a really cool partial vacuum 'glove in a bottle' in 200 easy steps. :) This was fun to watch and as many others have said, there are a lot of places where you have spots to have air pass through. Hopefully it will all end up cool in the end. :)
That's one heck of a conversation starter! Very cool!
Bottle of Silver Oak next to the mill? yummmm!!
I just wanted to say that I admire you and listen to you (your unique story telling, and analising of everything) while I work on my projects during the night.
Adam's habitual "thank you" after sneezing even when no one was there to say "bless you" at 47:37 is so funny
I always take that to be in response to that part of the audience, who have the reflex to think/utter the "bless you" to any sneeze. Nice implied interaction through the screen.
Ahhhhhh, watching the master at work. Zen time.
Hey Adam!❤from Northern California.
Adam,
The next time you need to cut large tubing and it needs to be precise your lathe is a better option than the table saw. Use rubber soft jaws to keep from marring the inside of the tubing and a parting tool to cut it to length. It is a much safer & more easily accurate way to do that task.
Needed this. Great to see someone who gets excited about projects like i do.
Surprised you haven't made a rotating platform for round glue applications, Adam.😉 If you do it regularly, 100% recommend making one! Just a nice, slow (but adjustable, depending on the glue time) rotation, just focus on squeezing out consistently, lovely job.👍 Also useful for sealing cylinders with silicone, etc.😊
and if designed right, great for welding too
@@graham_owens True, a variable speed would give you beautiful round welds...!
When my boss was in a hurry, he made us use an old record player set to 78
This was the best of one day builds. Adam, finding the solutions as he goes and us not knowing if it would work at all. I nearly had a panic attack when your unmounted the glove internally, I could not see that remounting! Couldn't take my eyes off this start to finish
I love your space themed vids
I needed that giggle at the start. Thanks for that.😆
47:57 that's what she said
Anyone?
This whole thing about holemaking, fitting satisfyingly and getting us there... hahaha glorious!
Love the terminology use of "un-smart" 😆 been there, done that, have a rental apartment there... 😀 i actually enjoyed this build immensely. Thank you 😊
11:15 -- you were right not to like that! As someone who works on a tablesaw frequently, I was getting stress sweats just watching it. Not sure what the better way to cut it would be, though.
I need my soul comforting with a carry case build for this, love me those box videos!
Nothing like cutting something with a scroll saw. Good tension. Watching heat (Packing tape works as a lubricate and suction helps). Fresh blade. Really help with the wondering. Making a few practice pattern to get in the zone helps too. Some days your head isn't in it. Other days it just happens.
Great build and I loved the trouble shooting aspect.
I was watching this thinking... I could've made the design and cut it all out on my 130 watt c02 laser in about 10 minutes🤣 that doesn't take the skills you used here in this video. Even being accurate within +/- .25" would be almost impossible for alot of people. Love it. Mythbusters literally set my career path. (Mech engineering and a whole lot of other random skills all crumpled together into a ball of miracles🤣) I wanted to be able to do anything I could think up. Keep it up, you entertained and educated me, and now I'm having my kids watch it. They all love everything requiring creativity, imagination and STEM.
He said thank you after sneezing like he knew someone was saying bless you.
I have been wondering if you have considered opening a museum of sorts to let people peruse your collection. You could free up a lot of space in your cave too. :)
The way your sanding it around 11:45 is exactly how wooden shells for drums are sanded
I just made some much smaller versions of this tube! Mine are filled with water, but had similar requirements for being airtight. I made the caps with an inner circle the size of the inner diameter of the tube, and sealed it with Weld-On 4.
Adam testing it out, glove box in his lap, right hand in the glove, left hand operating the vacuum setup, gave me real Tony Stark prototyping the Iron Man suit vibes
love the video as always, currently reading every tool is a hammer aswell... I made a circle cutting jig for my bandsaw and when i saw you freehanding those acrylic pieces i thought i would mention it... its super useful and pretty accurate too.
I know it doesn’t need to hold much pressure, and it would have been more machining work, but would chamfering the top and bottom into the tube have made an even better seal? As you created a vacuum inside the tube, it would have sucked the ends inward, further and further tightening the seal.
I would think making a chamfer would be a lot of work in that surface. I would say not worth it
Don't even need a chamfer, just add a ring to the bottom lid that fits somewhat snugly inside the tube (or machine a rabbit in the lid) and add a good gasket to the top outside the ring. You wouldn't need to glue the lid on at that point, the vacuum inside would hold it together.
@@arikbord2256Good idea. Would allow access to the inside too
I love that he used his tattoo for a rough estimate too double check the tube was 8in in the beginning… amazing
Someday there will be a community of makers building a detailed replica of Adam’s shop.
One of these days I'm going to find the time to sample Adam and his drumming to make a time lapse soundtrack for these. Oh, and his "squeals" of joy/ah-hah!/happiness.
We got a new sandblast cabinet for the shop and the seal on it the first time we fired it up was strong enough to pull the gloves erect into it. Hasn't held up but it was fun for the couple uses to feel the rubber gloves all pressurized like that.
An alternative to the washing up gloves you are using might be electricians gloves, they come in different thicknesses ( aka voltage ratings ) and are a long glove. We use them with a thin cotton inner glove to wick away the sweat and a goat skin outer glove for mechanical protection. A bit of talcum powder after use also to stop the gloves sticking themselves together.
The inner glove approach was nice! As an alternative you could have made the inner ring (for the black nitrile glove to slip over) a smaller diameter ( & no need for bolt holes on that piece) so it literally sits within the circle of bolts, and then use the outer ring to clamp it in between, so you wouldn't have to put the bolts thru the nitrile glove (god I wish I could post a sketch). Doesn't matter though because your method totally worked out! More than one way to skin a Tauntaun amirite?
Good idea!
Adam; "I'm going to create a vacuum." Nature; "Oh no you're not."
they better have this as an interactive exhibit in space museums
This episode, more than any of the ones I've watched before, feels like one of either: an Iron Man sequel, or a flashback when a character explains why they call him a One-handed Bandit.
Might be both.
anyone know what kind of tape adam used to protect the acrylic circles while bandsawing?
I also came here looking for this answer
Looked very much to me like 4" Scotch 'magic' tape.
Frog Tape
I believe it is heat shrink tape. Part number: DS-704C.
It looks like pre-mask for cut vinyl signage/graphics to me.
Handy place to keep your glove!
Intresting project.
I see that Adam has made the switch. Off go the Mars Yards. On go Tom Sachs' newest shoe - The General Purpose Shoe. Nice.
Iv'e done that sort of sanding so much, I keep a 5 & 10 Kg ( 6 & 12lb ) sand bag's on standby for downward pressure. they are also good for glue ups.
And that’s how J.P. Prewitt kept his hand looking like it did in the Fall 1973 Bulova watch catalog!
If you can adjust the vacuum coming in to be steady, you can take some non-acetic acid silicone rubber and start covering the joints. When you cover the leak the vacuum will increase. Silicone rubber is easy to remove, but if you use clear, leave it. If you do the soapy water to find the leak it'll be tough to dry & clean prior to sealing. Of course the leak could be the rubber glove...
I am working on an AX-2 'hard-suit' replica.
Rather than bladders and fabric, the AX program used rigid shells and slip-ring bearings to make 'space armor'.
Got a working sleeve; shoulder to wrist in 7 bearings.
There's video on TH-cam: 'transhuman exoskeleton mock-up' and 'whiffle articulation test'.
Upper torso shell/helmet coming soon...
I think one thing you can do to improve the seal is tighten the bolts on your ring-box flange in a star pattern. At least in pipefitting, you're supposed to do it that way, because if you don't the flange distorts and won't seal.
Awesome video as ever, quick question, was there a reason you didn't try a smoke test at the seals and glue joints to see where air was getting in?
Love the videos, good to see more in-depth content.
Might be possible to find the leak using smoke? Hold something like a sigaret along the sides and see where it seeps in? With soapy water you might not be able to get the water out easely.
One other way I'd recommend to plug up potential leaks is to use clear RTV along the outside of the joined edges where you glued together the acrylic pieces. I'd also use the RTV around the valve and gauge as well.
Adam is like a surgeon when he is building.
Oh dear.
Beautiful.
My favorite closed captioning from this episode was " Adam blows " as he cleans the Bridgeport. Thanks for the laugh
Amazing build! You definatelly need to finish this on another video 📹
Hey Wilson... You were always a great eyes and up neighbor.
Adam: *sneezes*
*gets bless you from no-one*
"Thank you."
That half head intro was great! Almost choked on my drink 🤣
Anyone else hold their breath during the cylinder cutting sequence? 😳
14:48 I felt that. The struggle is real.
Adam says he's never experienced wearing a spacesuit, but on his U2 flight, he came about as close as you can get.
One way to help to avoid scratches, not wearing rings, watches, bracelets etc. As a former jet engine mechanic those rules were to help prevent finger , hand etc. loss not scratches.
Should tell that chamber to turn that smile upside down.
Cheaper on Amazon too.
Love the editing or rather Non editing of this video!!
Adam I worked in a shop that worked on vacuum systems.
It very hard to deal with finding leaks you could use spray vacuum grease but that would be hard to clean off.
It could be a leak in the glove is self have gloves that were for electrical work and these would come new and fail their testing requirement.
A proper seal for a vacuum should be on the outside of the chamber, so that the pressure on the outside is pushing the seal inwards and therefore filling the gaps.
The way you did it is the other way around, the higher the vacuum gets, the worse the sealing gets since the pressure is infact enlarging the gap between seal and the housing.
when you accidentally start watching an hour and a half Adam Savage video 30 minutes before bed time
Ohhh I love that build 🙂
Btw, you could try coredrills in your drillstand to get larger round holes, might be easier than the scroll saw. There are some out there for plastics, wood and metal in a variety of sizes. My largest one is 13 cm in diameter.
Many years I worked precision machining thick acrylic for public aquariums. PVHO, pressurized vehicle human occupancy. Used in Atlantis, twice on Star Trek. The whale movie, and the nose of the research submersible in the opening credits of Star Trek Enterprise, and medical hyperbaric chambers. The way to finish cut that would be on a lathe with high speed tool ground with a real shallow angle, and almost a razor sharp edge. High speed slow feed so the chip comes off like a ribbon. Then it's polished with acrylic solvent so the cut marks are removed so the cut is as smooth as the cylinder. Assuming the cylinder is not round nor the end plate flat the end plate would be faced off flat then polished. The polish is for a good seal. All machine marks polished off, and all corners inside, and outside chamfered, and rounded.
I'm thinking "dead space " when I se this . Any one else ?
Nice prop / build !
I just visited the International Space Hall of Fame and Museum in Alamogordo, NM. They have HAM’s chimpanzee restraint suit and Mercury capsule. You should add them on to your list of future space themed builds.
Watching Adam rub that large cylinder against the sand paper awoke something in me... I don't know what yet.
As a Jim Henson fan, I liked that opening shot.
Its amazing how many round things have the size of whatever tape roll someone had on hand :D
bless you adam
Try bulkhead flanges for the meter and valve ports. Also, get a S/S needle valve for the vacuum port
It was very cool and at the one hour mark I'm yelling at the screen that you want the mounting rings on the outside so that you can easily take it apart to replace the neophrene glove should it tear and develop a leak, AND the pressure differential will compress rather than stretch the seals around the rings.
