Right? Really looking forward to seeing a scratch-built heavyweight wrecker! I'm assuming it'll be home to a large turbodiesel donk, very curious as to what they'll use. (6BT 12v or 3126 is my guess)
@@masondegaulle5731 ...... I'd love to see them use a 6BT! I doubt they will though. Matt seems to frown on diesels pretty hard. They'll probably use a stroker motor.

Darn that’s a heavy chassis! One of the things I love watching is how your builds are a family/friend affair. Everyone is down at the shop hanging out! Cant wait to see how this wrecker turns out!
Matt, I hope you tell Rudy how proud you are of him. There are very few young men with his experience and work ethic. I know I am proud of him, keep up the great work Rudy.
Love the channel but I have my concerns about this thing. Ground clearance, track access and maneuverability challenges aside costs, pollution, damages I obviously know nothing about this, it's just a guess from watching other rescues from the channel so please don't kill me :D We'll see..
@@Platypus_Warrior from what I think I understood in this video, this rig does not need to be as nimble as the MORRvaire because it's being specifically built for heavier rescues like camper vans. So basically as long as this rig can get anywhere a heavy vehicle can get stuck.
@@Alurpal80 I get it now. It's more like making the company more versatile in the kind of rescue they can take. I guess they wouldn't show much of the fails or the jobs they had to turn down. Thanks

Wow, the ultimate in "Mine is Bigger Than Your's"..!! Can hardly wait to see it on the road. Thanks for taking us along. Cheers Richard & Judy Hyde Park
Hey Rudy! If I can give a little unsolicited advice on welding? You are relying on gas and fire to keep the oxygen out of the weld. Welding without flux can lead to the molten metal instantly going bad. Everytime you make a puddle you need to point the flame into it to keep the oxygen in the air away. Then as you let off keep the nozzle pointed at it until it gets solid. Tacks, stops, and starts. Always grind a feather edge to restart on so you don't get those cold spots. Really push into a cold start to melt the puddle before you start dragging. Don't be afraid of melting the whole parent metal. Don't just glue on the surface. Wobble side to side slowly to widen the puddle but don't let air in. I'm trying to keep it simple so sorry for a lack of detail. See the puddle young welder.
C'est vraiment le meilleure et le plus synthétique commentaire sur le soudage que je n'ai jamais lu. Vous expliquez si bien les règles de bases qu'il faut absolument respecter si on veut réussir une parfaite soudure: ne jamais laisser l'oxygène entrer en contact avec le bain de fusion ainsi que le geste à avoir du début jusqu'à la fin de la soudure. On sent le professionnel passionné de Vulcain 😏
Pressure vessels are cylindrical for a reason. It's to avoid any concentrated shear stresses. A boxed square tube frame is loaded with shear stresses. Best case, it's just going to leak. Worst case, it bursts, and someone gets hurt.
@@WEMS20 I do think that it is a bad idea to use the square frame as an air tank. I believe that it will eventually fail due to contraction and expansion, most likely at one of the welds from the studs that they welded in. And there is also the moisture problem that is going to build up inside the frame that is unprotected against corrosion. I think that this truck is going to be big enough for two well placed air cylinders or tanks. Much easier with maintenance or to replace as well, and no risk damaging the frame in the long run. Even regular air tanks do not have an eternal life.
Matt, I've been watching your show for quite a while and really appreciate your "make it happen" approach to things. Unfortunately, in this case, you're wrong. As an aerospace engineer, a pressurized vessel that is subject to bending and torsional stresses is a very complex design problem (pressurized aircraft fuselages). While your design will likely not fail catastrophically (ie explosively), your pressurized frame will fail at or near the 90 deg corners adjacent to your welds due to stress concentration, aggravated by the accelerated corrosion caused by moisture, and additional thermal stresses of rapidly cooling air when pressure is released. In pressurized vessel design: Sphere = best, cylinder with spherical ends = 2nd best, cylinder with flat ends = difficult, rectangular/square = bad/dangerous. Not really something to "make happen". Recommend that you build a solid frame, and leave it at that, and incorporate an air cylinder in an appropriate enclosure.
@@MattsOffRoadRecovery That PSI should scare you but it doesn't seem to. That force is, cumulatively, well over 100,000 pounds exerted on the metal. If it let go sudddenly, it could cause major damage or injury. It's not worth the risk! Boxing the frame is a great idea, but please undo the pressure vessel bit right away.
@@MattsOffRoadRecovery Another mechanical engineer weighing in here, please please do not do that. 80 psi is not a low number - those 100k pounds of force are all concentrated along the weld seam. Add in your frame torsion / bending / shear stresses during driving, that's asking a lot. A 10 gal air tank can be had for $50.
@@MattsOffRoadRecovery Problem is, it probably will work. Then one day under all sorts of torque it decides not to work and maybe you'll never know what happened, or worse, it blows straight out to the side and decapitates a family of six watching you and your big truck from fifty feet away. Go experiment with frame tanks on a personal toy, not on a business truck.
I love that you've got Casey involved. He has experience with fabrication and using the equipment, along with a really great personality. I can't wait to see how this build goes and how it's used.
hey, you guys should try using the TIG to repair your small leaks, just grab the torch and make a fusion pass over the leak, give it a little weave to cover more surface area. Drilling out and filling with MIG takes way longer and you're not regaining much if anything structurally.
There's a reason air tanks aren't made with flat surfaces!! Just put in a real air tank, trying to make the frame the tanks is nothing but trouble, it won't be strong enough for good pressures. Seriously the truck is massive, you have PLENTY of space for proper air tanks!
Another exciting build. Through Matt's Off Road Recovery, I have learned about Fab Rats, Robby Layton, and Casey LaDelle's channel. All are great folks that have great content. Rudy's welding is amazing. he has a great talent.
The build episodes are just as fantastic as the recoveries! I love to work,fix and build on things, so this is great! You all are so universal and talented. My hats off to the whole crew. The highlight of this channel is the love, respect, appreciation and kind hearts each of you have. From your very first video until now, you all have remained true to who you are. Thank you for showing positive influences all the time. The world needs it now, more than ever! God Bless!
Can’t wait to see this rig rolling. A build like this really shows who’s who and what’s what. Between the bunch of you, there is some good ideas and good work.
First of all, HUGE fan. HOWEVER, as a mechanical engineer (not a certified PE) but still a guy who’s job it is to design compressed air systems, I’m concerned about the frame/tank. Compressed air (wet air) causes worse corrosion than air or water on their own. It’s a regular occurrence the water in bottom of tanks rusts the tanks out. I’d be concerned corrosion from this starts to eat into the thickness and rigidity of the frame unless you add a compressed air dryer. Let me know if I can help out. Without drying, minimum a good condensate drain the frame is gonna have less than 15 yr service. I hope I’m wrong. To only have 10 gallons of air the tank to replace this idea is less than 60 pounds and a couple hundred bucks to do it correctly AND not rust this brand new frame out. A truck this size won’t miss the 12” diameter to do the job right. Again, I hope I’m wrong. Love the idea. Paul’s bumper was just a lot lower chance than the frame the vehicle rides on.
Glad that so many people are jumping on this point. The 4x4 community's current fascination with DIY pressure vessels is going to result in a high-profile accident and closed-casket funeral, sooner or later. It's particularly baffling to see it on these bespoke builds where a commercial air cylinder can be procured in advance and then designed into a protected space on the vehicle.
@@manuhonkanen2111 it'll obviously have a compressor onboard, so you just make sure you can bypass the frame tank and run either straight off the compresser, or add an additional 1-2 gallon buffer tank that can easily tuck away inside.
@@amlee7 for pressurized air yes, but there are many square/box steep bumpers that double as water or oil tanks. Plenty of JK jeep aftermarket box steel bumpers made to hold water.
I am a heavy diesel mechanic from the north east. I am not a fan of doing frame tank because of moisture. But i guess being in the desert means less moisture so should work just fine. Anyway this build is going to be epic.
There is less moisture on the outside but they need to worry about the moisture on the inside rusting it out. The water condenses from compression and gets inside the frame. It's better to use an air tank with the proper asme certification if it's going into commercial service. The drain holes will be in the right place, built to handle the pressure, if anything happens to it you can just buy a standard replacement tank.
Woke up in Holbrook, Arizona heading for home (Yuma) on Monday. Hadn’t seen my favorite TH-cam channels in too long. Heading down the road, my wife breaks into Ed’s weather report…then we started to laugh. Love her and you all! Thanks!
I love how the whole You Tube Off Road Recovery team has come together to help each other!! Gives me hope for our future!! Thanks Guys & Gals!! You’re the Best!!
Well WOW , that is definitely the next step of MATT"S Off Road Recovery. The best part is you'r building it from scratch and that to doesn't get any better then that. Outstanding results from everyone to pull that of in a short time frame. Super stoked to see the next step. Cheers
Looking awesome Matt's recovery. This baby should be a good asset to your other recovery vehicles! Great crew helping out! Can't wait to see it in action!
only need a 54 inch mickey thompson baja claw to break them. they are tuff no doubt but the meritor diffs that came under then MRAPs as well are stronger, but dont turn as sharp. As for what these guys are gonna do with them, they will probably never have a breakage
For avoiding leaks in your next tank, grind the end of each weld before starting the next weld on top of it. The last 3/8" of the weld will have a tiny bit of porosity that will often leak air/fluid. Grind that porosity out and you will have better success.
sounds like you are a pressure welder, (pressure vessels and pipelines. Here in Canada, the term is "B" Pressure welder. Maybe the same down south? not sure.
Poor Casey probably had nightmares after working with you guys lol. Great to see him helping out, didn't hardly recognize him in the last part with a MORR shirt lol.
Really great seeing Casey teaming up with Matt on a project. Found his channel a month ago and really enjoy watching his recoveries and other projects on his channel.
Gotta say I'm impressed with the fab work, and I'm hard to impress! Most heavy frame fab I've done we set up upside down just works out nicer. Loved the screw jack & drill trick just did the same last week . Superb craftmanship!
Dual shield fluxcore is a good welding process to use for frames and such. It's what our company uses for all structural welds on truck frames. Also anything holding pressure should be cylinder with domed ends. Even if reinforced the flat spaces will bulge. I like the idea it sounds cool but there's alot of things that can go wrong there specially using short arc MIG process. Just food for thought! Can't wait till it's finished it's going to BE EPIC
I've been watching Casey for a short time. The bar and chain to make a "Rope Windlass" was brilliant. The thing I like about Casey is he uses the K.I.S.S. method. He keeps it simple. He as well as the rest of you guys(Luv ya too Lizzy) do not appear to have the curse of ego which often ends in overcomplication and hurt feelings. It was amazing to watch you all work together and function like a team and not overopinionated individuals. My only complaint is ya'all are too far away to help this old Texas vet to turn my also (old) avalanche into a project vehicle! (I can dream) All of the players in this vid, keep the vids coming. If I am going to waste time watching vids, I would rather be watching ya'all! Thank you!
Done construction & demolition, used that "rope windlass" idea, although over here in Devon uk we called it " Rope Tournique", Just one observation, when its really wound up & under great pressure dont ever let it slip out of your grip, the handle can take off like a torpedo!
@@Stoneycombe Which is why the Romans used it in conjunction with the elasticity of wood to use it to propel larger weapons of was.

I always carry ropes an chain due to their versatility of application. Thank you for your comment sir.
This is going to be one huge recovery vehicle!!!!! With this group of recovery people they can build just about anything they need. Can’t wait to see how this turns out. Glad see Casey helping out with this project and the rest of these great people involved. Thanks again for sharing.☺️☺️☺️👍👍👍👍
Came here to say that Rudy's welds look really nice but was beaten to it ;) Looks like an awesome build and will be anxiously awaiting further installments. You folks rock!
Wow this looks like another awesome project great to see lizzy continuing with her welding skills and it’s great to see Tom Tom and Casey and Monty helping on this build
As I was reading the comments there is a lot of serious and accurate concerns about the air talk! Be safe and turn it into a extra fuel tank or some sort of creative oil cooler. We all want you guys to be around for a while.
Casey L and company for the save. "not my circus, not my monkeys" is the way you have to look at it sometimes. You can only do so much. Nice work. Another cool project is born. I've been wondering what they were going to do with those axles for a while.
To each his own but when weighing the mounting of a tank or two on the vehicle versus using the frame as one will end up causing way more issues than it solves. The internal corrosion caused by hot compressor air is one. The constant flex and weld cracks will end up being the deal breaker.
Agreed. Doesn't matter that they live in Utah, when the air is compressed moisture will condense inside the frame rails. It'll rust the welded joints from the inside out the full length of the tank. Plus all that fab work for an inferior pressure vessel. I'd just mount a 10 or 20 gallon tank somewhere.
@@Mick_A_Knuckle or two 5 gallons with an isolator valve in-between in the event one fails. At least that way they still have a 5 gallon tank left to hobble with.
As a mechanical engineer: Strong agree. On top of the structural integrity, reliability, and maintenance issues, if they're going to be running anything beyond like ~30psi, it's going to be a safety issue too. That's a lot of compressed air volume in a much-less-than-ideal pressure vessel that's also a stressed structural member and also often at chest-eye level. At some poin a side is going to tear off one of those and risk throwing debris and/or shrapnel at people nearby. Especially when target weight for the frame is so high, using cylindrical, purpose-built tanks is just the better solution.
After viewing this video twice and reading some of the comments below, and because I love geek stuff, I decided to do some quick energy calculations on your rectangular tank design. Given a spec size of 93 x 7 x1.74 in inches for a volume of 1132 cubic inches, at 50psi the tank will be storing a bit over 82 thousand pounds of total pressure!! The area force calculations are a bit involved, but the corners are where bending moment forces are greatest. ASME standards require reinforcement/thicker metal of the 'cap' end plates. At a minimum I would suggest you put in perpendicular reinforcements and you should probably weld safety 'catch' plate(s) on the cabin side. As it stands if your design fails catastrophically someone could get a butt full of shrapnel. For a variety of other reasons this design will not serve you well in the long run. Just use a cylinder tank designed for the application.
They are already making several other mistakes so I don't think that "getting it right" is at the top of their list. More like trying to make it work". I'm not going to question your calculations but I personally don't understand how 50 psi of air spread over such a large area works out 82,000 pounds of force. Nevertheless making use of tanks designed for holding air pressure would by far be a smarter choice.
@@crazyoilfieldmechanic3195 It's 50 Pounds Per Square Inch. Each side is 93x7 if Leonardo is correct, so just those sides have 651 square inches. 651x50 is 32550 pounds of force. x2 as there are both left and right sides, that's 65100 pounds. The top and bottom add another 16275 together and caps 1050, so 82425 lbs. Now that sounds like a lot, but a standard 100+psi tank only has 1/8" steel. This frame is MUCH thicker. Also tanks tend to stay in one piece when they fail, but rip open violently. So shrapnel isn't that likely.
@@christopherrto The difference with cylindrical tanks is that they're cylindrical, so the stress on the metal attempts to pull it apart. In contrast, with a box design, all the corners serve to concentrate the stresses at the welds, which are the weakest points. It's a cool idea, but for both safety and reliability, Leonardo is absolutely correct. The design is fundamentally flawed. They need to purchase some properly designed and tested cylindrical pressure tanks.
Leo and Stephen are on target with their points. Additionally, pressure tanks are are not put into structural loads. This section of the frame’s stress will multiply with this internal pressure. Can’t wait to see this finished and rolling on the road. Hope it all turns out good in the end. I agree, just add a tank… even a re-certified nitrogen tank would be safer and hold more air than they me need.
Don't worry. After a few runs, flexing the frame, it will probably leak and they'll give up on the idea. The part I don't understand is this thing is going to be huge and will probably have plenty of room for a tank.
PLEASE, PLEASE, PLEASE use a face shield when using grinding tools. I've personally seen the life changing effects of a cut off wheel when it explodes. You NEVER get an eyeball back when damaged like a cut off wheel can do. Also note: If these are paid employees, you're opening up a big can of legal worms dealing with injuries like those.
I would add that this is likely because of the 1 million subscribers, likely only 2-3 are waiting for that game to start, the rest could really care less.
Looks amazing, i'm sure there be a awesome wrecker :) however that inframe air is a bad idea which would cause problem and as well a potential dangerous issue. I do agree at most comment regarding this issue. There is reason by most use cylindrical and sperical tanks for air pressure tank.
I am no expert but I wouldn't recommend using the frame as an air tank for 2 reasons: A) Water is a natural by-product of compressing air due to the condensing process. The water can rust the frame from the inside out over time. B) Air tanks are always round due to the increased strength. I found out (the hard way) that square doesn't work to well.
I wish TH-cam had a “love button” that you could press repeatedly to add more approval. Wicked cool project! I can’t wait for the rest of the episodes.
This is super cool to see being built from the ground up, from raw materials to a whole rig. The frame rails being used as air tanks is one of the most genius things I've ever seen
You guys gave me the chills pressure testing with air....The chances of living through a seam failure are slim as the potential energy at 120 psi is in the hundreds of thousands...real scary... That's why engineers test with water "Hydrotest"
I hope your "air frame" works out well. It looks good and it's a super trick idea. It's just that air pressure IS one of the, if not the, most dangerous forms of stored energy and it can be extremely unpredictable. I really love watching your builds. All your videos actually.
As an Engineer, there are some really good reasons there are very particular and specific ASME boiler & pressure vessel codes. While I understand why this seems like a good idea, I can assure you that it is not.
@@danielanderson2189 ASME B&PV code. Section II part A for ferrous Materials used in pressure vessels and section VIII Rules for Construction of Pressure Vessels. What they are doing could be quite dangerous and is entirely inadequate from an engineering and design standpoint. The materials, design, welding, and testing were very bad. If they’re luck, they’ll just very quickly develop weld cracking that leaks off all their pressure and will get tired of chasing leaks and welds to fix. If they’re not lucky, they’ll all be riding around in a ticking time bomb waiting for it to explode and someone to catch some shrapnel. That clearly contains far more energy than they begin to realize…even testing it the way they were makes that very clear, you don’t use compressed air! They have no idea what they’re doing and shouldn’t be doing it. It won’t work for long.
I'm sure that it is just a random coincidence that commercially available pressure tanks are always domed cylinders. Don't you bring in all your science and experience. Riding around on top of a potential bomb is a great idea. All of that just to save the space of a 10 gallon pressure tank?
@@ryanslaback9418 Air pressure and moisture in a structural member.That is why nasa blows rockets up.Must be just a youtube thing.I have a propane tank mounted to the frame.175 psi.
I missed something, I thought they were pressurizing it to find spots in the weld that would let grime and moisture inside the frame. Why is it meant to hold pressure?
@@Lowkey_ID I am assuming to hold air for the air brakes and after reading some comments maybe for airing up the tires after getting off the soft sand.
I can't wait to see this finished! After seeing the MORRVAIR finished (mostly) and the Banana being rebuilt I know this new truck will be just as capable.
This is going to be a fun build to watch. Casey being there is a nice touch, he is a good guy. As for all the naysayers about the in-frame air tank, this is NOT your build, this is for entertainment for you to watch, do not like what he is doing, then do not watch it. Matt and his crew know what they are doing and if something is a fail, then they will make it better.
Just what I wanted to build! One thing scares me though, I wanted to do my frame the same way until I looked into it and found airtanks that had failed and resulted in a massive explosion. If you are lucky it will just rip the frame open and no body will get hurt. Plus the compressed air will accumulate water in the frame and rust unless you drain it nearly daily. I am just going to run a air tank now.
I was thinking the same. These tanks should be hydro tested to 150% max pressure and also make sure to mount a drain valve at the lowest point or make sure you drain with the opposite end up a bit. And a PRV.
@@devinwarwick yeah i probably would have went withsomething thicker than 3/16 plate and recessed it a touch so i could lay a nice strong bead then pressure test to 200% the goal pressure...make sure ive got plenty of opportunity before catasrtophic failure
In low-humidity areas like where they are, you get MUCH less moisture in the tank. I've lived where the humidity doesn't get above 20% and you'll get a few cups of water in a tank over a period of a couple months. I now live where the humidity is considered high and you'll get that much in a week.
I can't wait to see the look on some stuck guy's face when he makes a call, expecting the Banana, and THIS behemoth comes along! Please tell me you are painting this Banana Yellow. :D I love that you are using the frame as an air tank. This rig is going to be awesome! Hello to Casey, and Tom Tom, thanks for your support and know how using the angle thingy lol. Great to see Ed as well. Hope all the crew is well and look forward to the next episode. Be safe and God Bless.
@@brandonmcandrew4859 Why not? 1/4 inch steel box, make it air tight and you have 10 gallons of air tank without the extra weight of external tanks. I have seen a lot of off roaders do this with bumpers and such. Otherwise wasted space being put to use.
Welding the frame to hold compressed air is harder than it sounds. If you are seeing leaks there will be weak spots that you don't see. Don't worry, they will show up once you get off road.
yep, it's a terrible idea, strength wise as well flat surfaces are terrible for holding pressure. The truck is massive, they need to just put in a proper off the shelf air tank made for the job!
I worked in a vessel shop building high compression gas compressors and many air tested tanks that would hold oil within the structure. We would rarely use mig on such thick materials due to it's poor penetration on stops starts leading to pin holes. You can tail out with the mig not leaving the porosity or use grinders on the stops starts and following and religious process of rooting in a first pass of E6010 covered by E7018 SMAW or Shielded metal arc or STICK. STICK has much better penetrative characteristics. The frames We would build were 40 to 60' long weighing between 40 to 50 tons just the frame. On those frames we would use heavy deposit high voltage flux core which would dig in well to thick metal in multiple passes. Was a fabricator welder for years and an instructor in the local trades school. I have learned a great deal from you folks here is only a small bit of my knowledge. Great project and keep going thanks!
Let me just say, Rudy is an excellent welder. His welds look SO good

Hey Rudy! If I can give a little unsolicited advice on welding? You are relying on gas and fire to keep the oxygen out of the weld. Welding without flux can lead to the molten metal instantly going bad. Everytime you make a puddle you need to point the flame into it to keep the oxygen in the air away. Then as you let off keep the nozzle pointed at it until it gets solid.
Tacks, stops, and starts. Always grind a feather edge to restart on so you don't get those cold spots. Really push into a cold start to melt the puddle before you start dragging. Don't be afraid of melting the whole parent metal. Don't just glue on the surface. Wobble side to side slowly to widen the puddle but don't let air in.
I'm trying to keep it simple so sorry for a lack of detail.
See the puddle young welder.
C'est vraiment le meilleure et le plus synthétique commentaire sur le soudage que je n'ai jamais lu.
Vous expliquez si bien les règles de bases qu'il faut absolument respecter si on veut réussir une parfaite soudure: ne jamais laisser l'oxygène entrer en contact avec le bain de fusion ainsi que le geste à avoir du début jusqu'à la fin de la soudure. On sent le professionnel passionné de Vulcain 😏
That is so freaking cool that y'all had Casey come out and help start the build!!! He is definitely one of my favorites
Pressure vessels are cylindrical for a reason. It's to avoid any concentrated shear stresses. A boxed square tube frame is loaded with shear stresses. Best case, it's just going to leak. Worst case, it bursts, and someone gets hurt.
At 100psi it will likely be fine.
Above 1,000psi, I would not trust it.
Sounds like we might all get to learn together. Science! 🇺🇲
Steel is pretty ductile, eventually a leak or even a crack might appear, but flying shrapnel seems pretty farfetched to me.
@@insAneTunA exactly. It will leak and might hurts the structure of the frame, but there's a 0% chance 100psi explodes that steel.
@@WEMS20 I agree👍
@@WEMS20 I do think that it is a bad idea to use the square frame as an air tank. I believe that it will eventually fail due to contraction and expansion, most likely at one of the welds from the studs that they welded in. And there is also the moisture problem that is going to build up inside the frame that is unprotected against corrosion. I think that this truck is going to be big enough for two well placed air cylinders or tanks. Much easier with maintenance or to replace as well, and no risk damaging the frame in the long run. Even regular air tanks do not have an eternal life.
Matt, I've been watching your show for quite a while and really appreciate your "make it happen" approach to things. Unfortunately, in this case, you're wrong. As an aerospace engineer, a pressurized vessel that is subject to bending and torsional stresses is a very complex design problem (pressurized aircraft fuselages). While your design will likely not fail catastrophically (ie explosively), your pressurized frame will fail at or near the 90 deg corners adjacent to your welds due to stress concentration, aggravated by the accelerated corrosion caused by moisture, and additional thermal stresses of rapidly cooling air when pressure is released.
In pressurized vessel design: Sphere = best, cylinder with spherical ends = 2nd best, cylinder with flat ends = difficult, rectangular/square = bad/dangerous. Not really something to "make happen".
Recommend that you build a solid frame, and leave it at that, and incorporate an air cylinder in an appropriate enclosure.
@@MattsOffRoadRecovery That PSI should scare you but it doesn't seem to. That force is, cumulatively, well over 100,000 pounds exerted on the metal. If it let go sudddenly, it could cause major damage or injury. It's not worth the risk! Boxing the frame is a great idea, but please undo the pressure vessel bit right away.
@@MattsOffRoadRecovery A drivers front airbag will launch a person into the air with less than 5 psi.
Agree 100%. The only thing scarier than this tank is a fabricator that's not scared of this tank 🤣
@@MattsOffRoadRecovery Another mechanical engineer weighing in here, please please do not do that. 80 psi is not a low number - those 100k pounds of force are all concentrated along the weld seam. Add in your frame torsion / bending / shear stresses during driving, that's asking a lot. A 10 gal air tank can be had for $50.
@@MattsOffRoadRecovery Problem is, it probably will work.
Then one day under all sorts of torque it decides not to work and maybe you'll never know what happened, or worse, it blows straight out to the side and decapitates a family of six watching you and your big truck from fifty feet away.
Go experiment with frame tanks on a personal toy, not on a business truck.
I love that you've got Casey involved. He has experience with fabrication and using the equipment, along with a really great personality. I can't wait to see how this build goes and how it's used.
Great seeing Casey on the channel! Hope we get to see him joining y'all on those recoveries that came up.
hey, you guys should try using the TIG to repair your small leaks, just grab the torch and make a fusion pass over the leak, give it a little weave to cover more surface area. Drilling out and filling with MIG takes way longer and you're not regaining much if anything structurally.
I'm always impressed with Rudys welding skills. It's like every few months or so you can visually see them getting better and better.
There's a reason air tanks aren't made with flat surfaces!! Just put in a real air tank, trying to make the frame the tanks is nothing but trouble, it won't be strong enough for good pressures. Seriously the truck is massive, you have PLENTY of space for proper air tanks!
I'm with you on that.. I just gave a similar 2cents of input.
Some big tube bumpers would be another good option..
I think they're worried about the weight of the tanks, not their size...
@@WatanabeNoTsuna. 2 4 gallon tanks is not that heavy
Much safer to use the frame as a fuel tank🔥
Another exciting build. Through Matt's Off Road Recovery, I have learned about Fab Rats, Robby Layton, and Casey LaDelle's channel. All are great folks that have great content. Rudy's welding is amazing. he has a great talent.

I’ve really been enjoying Casey’s videos!
This build is epic and this has become one of my favorite channels! I watch every video!!
Can’t wait to see this rig rolling. A build like this really shows who’s who and what’s what. Between the bunch of you, there is some good ideas and good work.
i may not watch every post, but this has got to be one of the best groups and channels on TH-cam, all time. Good people, cool projects!
First of all, HUGE fan. HOWEVER, as a mechanical engineer (not a certified PE) but still a guy who’s job it is to design compressed air systems, I’m concerned about the frame/tank. Compressed air (wet air) causes worse corrosion than air or water on their own. It’s a regular occurrence the water in bottom of tanks rusts the tanks out. I’d be concerned corrosion from this starts to eat into the thickness and rigidity of the frame unless you add a compressed air dryer. Let me know if I can help out. Without drying, minimum a good condensate drain the frame is gonna have less than 15 yr service. I hope I’m wrong. To only have 10 gallons of air the tank to replace this idea is less than 60 pounds and a couple hundred bucks to do it correctly AND not rust this brand new frame out. A truck this size won’t miss the 12” diameter to do the job right. Again, I hope I’m wrong. Love the idea. Paul’s bumper was just a lot lower chance than the frame the vehicle rides on.
Maybe a drain will help.
@@mokumizu4318 totally unnecessary comment
Those axles should have air brakes and/or bags and will certainly need an air dryer. I'm curious if they are going with a diesel powerplant?
And a hair dryer 🤣
Glad that so many people are jumping on this point. The 4x4 community's current fascination with DIY pressure vessels is going to result in a high-profile accident and closed-casket funeral, sooner or later. It's particularly baffling to see it on these bespoke builds where a commercial air cylinder can be procured in advance and then designed into a protected space on the vehicle.
Although the frame tank was a good implementation based on the idea, I still think a proper on board air tank would suffice better in the long run!
Absolutely agreed! When the air is lost in the back of the desert it is not fun
@@manuhonkanen2111 it'll obviously have a compressor onboard, so you just make sure you can bypass the frame tank and run either straight off the compresser, or add an additional 1-2 gallon buffer tank that can easily tuck away inside.
Could always use them for water or oil tanks like a lot of bumpers are built for
@@ChevTecGroup TUBE bumpers. They are all tubes.
@@amlee7 for pressurized air yes, but there are many square/box steep bumpers that double as water or oil tanks. Plenty of JK jeep aftermarket box steel bumpers made to hold water.
Cool to see Casey around the shop. He seems like a really good dude. Love all the cross-overs you guys do.
That recovery truck is going to be a BEAST....Great Welding Rudy...And Great Video....
I am a heavy diesel mechanic from the north east. I am not a fan of doing frame tank because of moisture. But i guess being in the desert means less moisture so should work just fine. Anyway this build is going to be epic.
The frame is already rusted. Compressed air combined with rust is just bad.
This was my thought, maybe they can just oil the inside?
@@BenKloos no, don't! The oil could combust like a diesel.
There is less moisture on the outside but they need to worry about the moisture on the inside rusting it out. The water condenses from compression and gets inside the frame. It's better to use an air tank with the proper asme certification if it's going into commercial service. The drain holes will be in the right place, built to handle the pressure, if anything happens to it you can just buy a standard replacement tank.
@@lightningdemolition1964 I live here too. I still have to regularly drain my air tank regularly.
So great! I’m so glad you incorporated Casey. Every channel you are bringing along for the ride is so good. Thank you guys so much!
One word…INCREDIBLE! It’s so nice to see the entire MORR crew involved, including Lizzie. Shout out to Casey for his expertise. 👍

Matt you , Jamie , your family and friends are amassing people.You make this small world a better place .Thank You
Can't wait to see the suspension ideas you come up with. I did some heavy recovery in the military and never figured out how to break those axels.😎
only need a 54 inch mickey thompson baja claw to break them. they are tuff no doubt but the meritor diffs that came under then MRAPs as well are stronger, but dont turn as sharp.
As for what these guys are gonna do with them, they will probably never have a breakage
For avoiding leaks in your next tank, grind the end of each weld before starting the next weld on top of it. The last 3/8" of the weld will have a tiny bit of porosity that will often leak air/fluid. Grind that porosity out and you will have better success.
@Jeremy Hicks _ Pipeliner?

Really great seeing Casey teaming up with Matt on a project. Found his channel a month ago and really enjoy watching his recoveries and other projects on his channel.
The wealth of knowledge on this build is phenomenal as is the cooperation.
The wealth of knowledge should have realised that pressure vessel in the frame rail is a terrible idea.
Gotta say I'm impressed with the fab work, and I'm hard to impress! Most heavy frame fab I've done we set up upside down just works out nicer. Loved the screw jack & drill trick just did the same last week . Superb craftmanship!
Appreciation on Rudy welding... Rudy's beads are clean, his welds would be the star of this next build
Dual shield fluxcore is a good welding process to use for frames and such. It's what our company uses for all structural welds on truck frames. Also anything holding pressure should be cylinder with domed ends. Even if reinforced the flat spaces will bulge. I like the idea it sounds cool but there's alot of things that can go wrong there specially using short arc MIG process. Just food for thought! Can't wait till it's finished it's going to BE EPIC
I’d run SMAW before MIG. I agree tho, dual shielded FCAW would be the best.
Why does it have to be airtight?
I was thinking it would be a much safer idea and easier to just use air brake tanks designed for otr trucks.
@@apollo5751 if I had known I wouldn't have asked. We all learn new things. Sorry if I offended you.
I second the fluxcore wire.... Look into it.... Its better for heavier welding.....
I've been watching Casey for a short time. The bar and chain to make a "Rope Windlass" was brilliant. The thing I like about Casey is he uses the K.I.S.S. method. He keeps it simple. He as well as the rest of you guys(Luv ya too Lizzy) do not appear to have the curse of ego which often ends in overcomplication and hurt feelings. It was amazing to watch you all work together and function like a team and not overopinionated individuals. My only complaint is ya'all are too far away to help this old Texas vet to turn my also (old) avalanche into a project vehicle! (I can dream) All of the players in this vid, keep the vids coming.

Wow this looks like another awesome project great to see lizzy continuing with her welding skills and it’s great to see Tom Tom and Casey and Monty helping on this build
As I was reading the comments there is a lot of serious and accurate concerns about the air talk! Be safe and turn it into a extra fuel tank or some sort of creative oil cooler. We all want you guys to be around for a while.
Casey L and company for the save. "not my circus, not my monkeys" is the way you have to look at it sometimes. You can only do so much. Nice work. Another cool project is born. I've been wondering what they were going to do with those axles for a while.
To each his own but when weighing the mounting of a tank or two on the vehicle versus using the frame as one will end up causing way more issues than it solves. The internal corrosion caused by hot compressor air is one. The constant flex and weld cracks will end up being the deal breaker.
I was thinking the same thing. The air is going to contain a lot of humidity.
Agreed. Doesn't matter that they live in Utah, when the air is compressed moisture will condense inside the frame rails. It'll rust the welded joints from the inside out the full length of the tank. Plus all that fab work for an inferior pressure vessel. I'd just mount a 10 or 20 gallon tank somewhere.
The can put an air drier on it.
@@Mick_A_Knuckle or two 5 gallons with an isolator valve in-between in the event one fails. At least that way they still have a 5 gallon tank left to hobble with.
As a mechanical engineer: Strong agree. On top of the structural integrity, reliability, and maintenance issues, if they're going to be running anything beyond like ~30psi, it's going to be a safety issue too. That's a lot of compressed air volume in a much-less-than-ideal pressure vessel that's also a stressed structural member and also often at chest-eye level. At some poin a side is going to tear off one of those and risk throwing debris and/or shrapnel at people nearby.
Especially when target weight for the frame is so high, using cylindrical, purpose-built tanks is just the better solution.
After viewing this video twice and reading some of the comments below, and because I love geek stuff, I decided to do some quick energy calculations on your rectangular tank design. Given a spec size of 93 x 7 x1.74 in inches for a volume of 1132 cubic inches, at 50psi the tank will be storing a bit over 82 thousand pounds of total pressure!! The area force calculations are a bit involved, but the corners are where bending moment forces are greatest. ASME standards require reinforcement/thicker metal of the 'cap' end plates. At a minimum I would suggest you put in perpendicular reinforcements and you should probably weld safety 'catch' plate(s) on the cabin side. As it stands if your design fails catastrophically someone could get a butt full of shrapnel. For a variety of other reasons this design will not serve you well in the long run. Just use a cylinder tank designed for the application.
They are already making several other mistakes so I don't think that "getting it right" is at the top of their list. More like trying to make it work".
I'm not going to question your calculations but I personally don't understand how 50 psi of air spread over such a large area works out 82,000 pounds of force. Nevertheless making use of tanks designed for holding air pressure would by far be a smarter choice.
@@crazyoilfieldmechanic3195 It's 50 Pounds Per Square Inch. Each side is 93x7 if Leonardo is correct, so just those sides have 651 square inches. 651x50 is 32550 pounds of force. x2 as there are both left and right sides, that's 65100 pounds. The top and bottom add another 16275 together and caps 1050, so 82425 lbs.
Now that sounds like a lot, but a standard 100+psi tank only has 1/8" steel. This frame is MUCH thicker. Also tanks tend to stay in one piece when they fail, but rip open violently. So shrapnel isn't that likely.
@@christopherrto The difference with cylindrical tanks is that they're cylindrical, so the stress on the metal attempts to pull it apart. In contrast, with a box design, all the corners serve to concentrate the stresses at the welds, which are the weakest points. It's a cool idea, but for both safety and reliability, Leonardo is absolutely correct. The design is fundamentally flawed. They need to purchase some properly designed and tested cylindrical pressure tanks.
Leo and Stephen are on target with their points. Additionally, pressure tanks are are not put into structural loads. This section of the frame’s stress will multiply with this internal pressure. Can’t wait to see this finished and rolling on the road. Hope it all turns out good in the end. I agree, just add a tank… even a re-certified nitrogen tank would be safer and hold more air than they me need.
Don't worry. After a few runs, flexing the frame, it will probably leak and they'll give up on the idea. The part I don't understand is this thing is going to be huge and will probably have plenty of room for a tank.
PLEASE, PLEASE, PLEASE use a face shield when using grinding tools. I've personally seen the life changing effects of a cut off wheel when it explodes. You NEVER get an eyeball back when damaged like a cut off wheel can do. Also note: If these are paid employees, you're opening up a big can of legal worms dealing with injuries like those.

Looks amazing, i'm sure there be a awesome wrecker :) however that inframe air is a bad idea which would cause problem and as well a potential dangerous issue. I do agree at most comment regarding this issue. There is reason by most use cylindrical and sperical tanks for air pressure tank.
Wow, guys. That is a FRAME. Nice work. And literal bombproof axles. Can't wait to see this beast in action!
I am no expert but I wouldn't recommend using the frame as an air tank for 2 reasons:
A) Water is a natural by-product of compressing air due to the condensing process. The water can rust the frame from the inside out over time.
B) Air tanks are always round due to the increased strength. I found out (the hard way) that square doesn't work to well.
C) It's reducing the effective strength of the frame

You guys gave me the chills pressure testing with air....The chances of living through a seam failure are slim as the potential energy at 120 psi is in the hundreds of thousands...real scary... That's why engineers test with water "Hydrotest"

.. Yep... You guy's have got me... Got me good... I can't stop watching this channel...
I hope your "air frame" works out well. It looks good and it's a super trick idea. It's just that air pressure IS one of the, if not the, most dangerous forms of stored energy and it can be extremely unpredictable. I really love watching your builds. All your videos actually.
Hydraulic fluid also super dangerous under pressure. Google up hydraulic injection, and be prepared to be very scared
@@paullambert2668 ..... Hydraulic injection is terrible. Not extremely common either. Hydraulic pressure is powerful. It's not explosive though.
As an Engineer, there are some really good reasons there are very particular and specific ASME boiler & pressure vessel codes. While I understand why this seems like a good idea, I can assure you that it is not.
Asme 570?
@@danielanderson2189 ASME B&PV code. Section II part A for ferrous Materials used in pressure vessels and section VIII Rules for Construction of Pressure Vessels. What they are doing could be quite dangerous and is entirely inadequate from an engineering and design standpoint. The materials, design, welding, and testing were very bad. If they’re luck, they’ll just very quickly develop weld cracking that leaks off all their pressure and will get tired of chasing leaks and welds to fix. If they’re not lucky, they’ll all be riding around in a ticking time bomb waiting for it to explode and someone to catch some shrapnel. That clearly contains far more energy than they begin to realize…even testing it the way they were makes that very clear, you don’t use compressed air! They have no idea what they’re doing and shouldn’t be doing it. It won’t work for long.
@@REDSHlFT seeing him argue that "it's only 90psi it should be fine" is just proving you right even more.
I'm sure that it is just a random coincidence that commercially available pressure tanks are always domed cylinders. Don't you bring in all your science and experience. Riding around on top of a potential bomb is a great idea. All of that just to save the space of a 10 gallon pressure tank?

You may want to install a drain chock at the lowest point on your airtank/frame so the condensation can be drained periodically.
I was wondering about that myself, but wonder if the air is dry enough in Utah that it's not a problem?

I find it very disturbing when people make pressure vessels out of square and rectangle tubing or plate
I agree with your comment. There is a reason that air tanks and pressure vessels are round with domed ends.
I missed something, I thought they were pressurizing it to find spots in the weld that would let grime and moisture inside the frame. Why is it meant to hold pressure?
@@Lowkey_ID I am assuming to hold air for the air brakes and after reading some comments maybe for airing up the tires after getting off the soft sand.

I can't wait to see this finished! After seeing the MORRVAIR finished (mostly) and the Banana being rebuilt I know this new truck will be just as capable.
This is going to be a fun build to watch. Casey being there is a nice touch, he is a good guy. As for all the naysayers about the in-frame air tank, this is NOT your build, this is for entertainment for you to watch, do not like what he is doing, then do not watch it. Matt and his crew know what they are doing and if something is a fail, then they will make it better.
Just what I wanted to build! One thing scares me though, I wanted to do my frame the same way until I looked into it and found airtanks that had failed and resulted in a massive explosion. If you are lucky it will just rip the frame open and no body will get hurt. Plus the compressed air will accumulate water in the frame and rust unless you drain it nearly daily. I am just going to run a air tank now.
I was thinking the same. These tanks should be hydro tested to 150% max pressure and also make sure to mount a drain valve at the lowest point or make sure you drain with the opposite end up a bit. And a PRV.
@@devinwarwick yeah i probably would have went withsomething thicker than 3/16 plate and recessed it a touch so i could lay a nice strong bead then pressure test to 200% the goal pressure...make sure ive got plenty of opportunity before catasrtophic failure
In low-humidity areas like where they are, you get MUCH less moisture in the tank. I've lived where the humidity doesn't get above 20% and you'll get a few cups of water in a tank over a period of a couple months. I now live where the humidity is considered high and you'll get that much in a week.
@@ADBBuild on my kenworth I drained the tanks every day and even in dry climates it sometimes surprised me.
Even if they had none of those problems, they definitely loaded up those air tanks with metal shavings when they drilled all those holes.
I can't wait to see the look on some stuck guy's face when he makes a call, expecting the Banana, and THIS behemoth comes along! Please tell me you are painting this Banana Yellow. :D I love that you are using the frame as an air tank. This rig is going to be awesome! Hello to Casey, and Tom Tom, thanks for your support and know how using the angle thingy lol. Great to see Ed as well. Hope all the crew is well and look forward to the next episode. Be safe and God Bless.
They should make the body a giant banana, like the Oscar Meyer Weinermobile.
So frame air tank i don't get it can someone explain why they are doing that
@@GrimResistance Suggest it to Matt, you never know...
@@brandonmcandrew4859 Why not? 1/4 inch steel box, make it air tight and you have 10 gallons of air tank without the extra weight of external tanks. I have seen a lot of off roaders do this with bumpers and such. Otherwise wasted space being put to use.
@@johnme7049 i see so you could fill up tires and that with the air I was just thinking of it in a different way altogether
Welding the frame to hold compressed air is harder than it sounds. If you are seeing leaks there will be weak spots that you don't see. Don't worry, they will show up once you get off road.
yep, it's a terrible idea, strength wise as well flat surfaces are terrible for holding pressure. The truck is massive, they need to just put in a proper off the shelf air tank made for the job!
Soapy water will find them quick. I meant while the welding was happening.
@@feeneysmechanical6215 Mother nature will ALWAYS find a way 😉😂
I’d guess with this team of guys and girls it’s achievable and I’m sure it be thought though
I was thinking the same thing. Im curious to see how this does in the long run vs just putting a regular compressed air tank somewhere on the rig.
I worked in a vessel shop building high compression gas compressors and many air tested tanks that would hold oil within the structure. We would rarely use mig on such thick materials due to it's poor penetration on stops starts leading to pin holes. You can tail out with the mig not leaving the porosity or use grinders on the stops starts and following and religious process of rooting in a first pass of E6010 covered by E7018 SMAW or Shielded metal arc or STICK. STICK has much better penetrative characteristics. The frames We would build were 40 to 60' long weighing between 40 to 50 tons just the frame. On those frames we would use heavy deposit high voltage flux core which would dig in well to thick metal in multiple passes. Was a fabricator welder for years and an instructor in the local trades school. I have learned a great deal from you folks here is only a small bit of my knowledge. Great project and keep going thanks!
