I've built airplanes boats and cars, but never in my wildest dream to build a sub, My hats off to you!

Very nice! I had a similar idea years ago, but not living on a lake (or near one), I started building airplanes instead. Have fun, be careful!

hi, there is a company called sofnolime, that makes a material called CaOH. we took the cabin air in the sub and circulated it with a fan through this chemical. The chemical removes exhaled CO2 and allows us to stay down with almost no supplemental oxygen. We carry a small bottle of oxygen with us and release a small amount every 30 min or so. We also have a CO2 meter to tell us if the scrubber is working and to let us know when the CaOH is saturated. Email me for info on ballast

Bet this all started out with a couple of beers and a bull session.

I've wanted to do this all my life ,when you tell small minded people this dream they laugh,keep living your dreams !!!!!!!!!

And the winner of the Internet ... MrChevelleMan!

You've got an interesting little hobby there. I've often thought about doing that with a propane tank. I'm impressed that you've done it and done it rather well. Kudos! I like your shop too!

How did you make sure the ones inside could breathe? How did you manage to do the motor? Just by placing the entire thing on the outside? How deep can it go? How heavy is it? Outstanding work!

I drew up plans for a propane sub just the other day and wondered if anyone else had thought of it - now I know. Good job. The things that had me most confused were sealing the ports and propulsion. It looked like you used external motors on the planes as well as a main prop being driven from a motor on the inside. How did you seal the driveshaft?

Clever design. I really feel something stirring. Think I'd like a periscope and torpedo tubes and a deck gun........and to be 20 years younger!

so awesome! i wish you had gotten some closeup shots of the hatch, and the sealing mechanism.

Very nice engineering project! I loved watching, but I turned off the music almost immediately. I would rather have heard you describing each image and what was happening at that stage. You would be way more interesting than a noisy sound track.

Bad part was they had 3 alarm Chili the night before... Lets do this in a water tank truck! Oh and the Theme from A-Team would have worked great here.

This is the first homemade sub ive seen that uses a hydraulic motor with thru-mounted hoses. Brilliant! I was wondering why so many people choose stuffing boxes when this system would be superior. Well done!

@@steveseymour1739 Exactly! 😁 I've been toying around with the idea on my drafting table for some time now. Using a 100k gal propane tank with curved railroad track bent into ribs... Just can't justify the $140,000 and thousands of man-hours to the wife for some reason. 🤔🤣😂 Again, well done! Its is very encouraging to see an enthusiast have such a well built and product!

I have always had a idea to do this, except for the time, money material and guts to do it. I will not go into the fact of not likeing closed in places and being under water to boot. But you sir are a genius. (and balls I might add).

haha well that's flattering! thank you. There is no drive shaft. There is an electric motor connected to a hydraulic pump on the inside. We welded pipe collars to the hull and connected hoses from the pump to the hydraulic motor on the outside. But honestly this system was a waste of time and space. The two motors in the front pull it faster while using less juice. If i could go back id just put two more trolling motors on the back.

WOW Very EnGenius!

What sized tanks did you use for the main body and lower conning tower?

absolutely amazing.

You should have painted it yellow Beatles fans would love it, your music choice may have also changed all a + :-)

I am impressed. Made me a subscriber, hope you add more videos. God I love KZread.

I would totally build this but where would i get the tank? Maybe even a bigger one. Im so sad i just found this cx its awesone imma check your channel for more

This is really brilliant. I would love to see the math calculations used to make this happen. And of course some idea of the costs involved. The labor and Engineering calcs and Design time of course are what made this happen.. along with some great fabrication skills, and very creative use of std. materials.

@steveseymour1739

The math is fairly basic. The sub needs to weigh the same amount as the water that it displaces to be neutrality buoyant. We spent $5,000 total on the sub ( a majority of that was batteries and trolling motors and electronics) and it took 2 months to design and build.

Thanks for showing us this. Your workmanship is excellent to say the least. From what I was seeing you thought through every move before you made it. Nicely done. Do you have anything in place for emergency egress?

beyond cool!

very good job mate.

This is amazing. How hard is it to balance the Ballast for even Dive? How deep can she run? Have you videos coming out with actually putting her underway? What is the depth range and how do you keep your tanks from frosting rise? I have so many questions I hope I am not over stepping. this is awesome and I am so curious now.... Very nice.

I have a few of these tanks laying around including a tank that stands 5ft tall and about 55ft long. What would you recommend?

I want one. Going to try and build this myself, maybe slightly larger...

How do you keep the hatch sealed?

You just got a sub (lol) man, she's Beautiful and you guys are geniuses!!! I've built from scratch a lot of things before but a safe and fuctional MANed submarine is indeed one of the most difficult things that anyone could EVER build! It would be much easier to build a flying machine from scratch than this... You guys have GOT to take her somewhere with clear water and take some awesome underwater HD vid!!! I'm happy to sub your channel and will follow you closely! Keep it up!

Thanks kool, ideas ideas...

whats the max depth it would handle? Great submarine btw

hello im planning on building one of these after i finish welding class and i have a few questions if you dont mind me asking: how do you breath in there? whats the oxygen source. how do you set up the ballast system? and where can i find more information on it? how did you make the pressure cooker hatch? and how deep can it goes? thank you :)

hey thank you! we had fun

Wonder if anyone has ever attempted to make a submarine out of an old railroad tank car.....that would be a good one, and would hold multiple people too

amazeing , well done

I am definitely interested in making one of these! But, I need to know the overall price that you payed to make this. Can you tell me what it all came out to?

did it leak at all?

Im trying to do the same thing, but i cant find propane tanks ANYWHERE. Where could i find one for cheap?

how much did it cost to build the sub? i want to build one so bad

How many permits did you need to launch this? I ask because I live in california, the land of laws, regulations and red tape.

What kind of glass are you using and who makes it?

I tryed to build one of these way back in the late 80's How in the heck did you get ride of the green sludge that makes propane stink ?

Hey Man, How does this submarine sink and float again? And also what are the blue tank looking this beside the propane tank?

what type of propeller did you use?

do you sell plans how to video or anything like that if so I would be interested thx

What kind of pressure gauge did you use? Also do you do you know how much weight in concrete you needed to make it able to raise and lower with the offsetting of the ballast? Thanks in advance.

The pressure gauge that we used is marked in meters of water depth but, one marked in psi will work. You would need to determine the maximum psi your sub can safely descend to. The concrete in the emergency drop weight is 1300 lbs. We have removable steel weights to compensate for heavier or lighter occupants.

ok this is awesome! im saving this vid but I have a question or two. how many gallon is the propane tank? how did you not blow yourself up by cutting it with the torch? and whats the depth that it can dive?

Thats cool, How long did it take?

you are not alone my friend.

Very nice. How deep does it go?

Any chance in some blueprints?

Wow neat! Keep me posted on your progress. I would be thrilled to answer any questions you may have!

I was amazed at the results! did not think it was going to be so good. I am building a submarine myself. but not of propane tanks, since I thought and think it's harder that way .. dont think i will get ass deep ass i want if its made that way. how low can you go? how thick is the hull? do not see a battery somewhere? great sub tho! bring more videos = D

Hey you know that the sub if submerged underwater a few feet, then if you try to surface it you will need to expel water out of the tanks correct? What if the sub stays in neutral buoyancy rather then coming up?

very cool man... how much did the whole build cost?

I noticed the primer,is it the epoxy clear?And is the paint EPDM rubber coating?

ChevelleMan Judging from the pix this is in place on a constructed water ski pond in ...Ashland Nebraska?

how much money did you spend on it roughly? what's its working depth and how long can it stays underwater?

how much was it to do this?

Now just make it bigger. Then another one a bit bigger. It would be nice to end up with one the size of a large SUV so you could remain under water in comfort for many hours. The development should go to large SUV size with comfortable interior and you would have a marketable product for the masses. A new class of personal watercraft. Sailboats, Powerboats, SUBMARINES! Imagine getting into the family submarine for an underwater cruise! Opens a whole other world for people to enjoy.

and just to clarify... when you want to submerge, you fill those tanks with water. NOTE: this does not mean you use water as weight. It simply means you use the water to reduce the volume of total water the sub is displacing.

Plus I'm sure it's insanely fun.

how you open air tanks ?

Hey no problem, its super simple to control ballast, theres a valve for the front and a valve for the back. We've had it to 32 ft and we hit bottom. Yes check out Garrettcaleb12 he posted the videos.

y u no paint it yellow?

Anyone can say they scuba dive but who can say they a have a submarine?

what are the skills i need to know to be able to construct one? im already a very bright guy who is able to turn junk into gadgets

Dude, that is sick!!!! How deep will she go? I am sure not extremely deep. Also, would you wear a SCUBA inside the sub, in case you had to scuttle/ditch underwater?

***** I think the weak looking windows will break first, so no risk of the hull to crush. But yes, pressure will quite rapidly increase then and sub will be flooding. I think, in general rapid increase of pressure is not as dangerous as rapid decrease. If you are not too deep you might stay conscious after a windows breaks, although you might pop your eardrums. When flooded you might be able to open and escape through the hatch. Anyways, there are no more video updates from this project by MrChevelleMan so he might not have made it. Great looking boat anyhow and good design and welding work!

If so then I guess you can't call an airplane that can not make it to space an airplane. Our goal was to touch the bottom of a 12ft pond. We built it to survive 100ft deep. Lol after accomplishing our goal. We took it to a rock quarry and went to 35 ft. Multiple times without any issues. But that was a very clever comment because now I want to post the footage of our most recent dive.

Todd $5,000. The biggest costs were the batteries and trolling motors. Most of the other things were already on hand or were given to us.

most of the driving force comes from two trolling motors. And the compressed air comes from a home made air compressor that we built. =)

it is half inch lexan. got it from ebay (a sheet)

Will ich auch mal machen:-).

After complete o2 ventaliation the first cut on January 2013. Working on "Suercavation as applied to propulsion unit".

We can stay down way longer. We stay dry and we don't have to worry about decompression sickness if we come up too quickly.

well its pretty simple if you keep one thing in mind. The submarine is heavier than water and it will sink as soon as it is placed in the water. This is overcame by tanks called ballast tanks (mine are the blue ones on the outside.) To sink you must be more dense than water, and on the other hand to float you need to be less dense. To become less dense, you fill the ballast tanks with compressed air (which forces the water out) and then you will surface. just like filling a ballon.

What's the advantage of this over just scuba diving. Not being rude, genuinely curious.

The prop shaft does not go through the hull. The prop is mounted to an external hydraulic motor and the hydraulic hoses attach to pipe fittings that are welded to the hull. A hydraulic pump inside the sub is driven by an electric motor. This is not an efficient system but it does provide a lot of thrust.

@steveseymour1739

atrevido No, there is no need for gaskets because the rudder and bow planes are operated by hydraulic cylinders which have hoses that thread into fittings that are welded to the hull. Fluid pressure is transferred to the cylinders from inside the sub by manual operation. No mechanical linkage goes through the hull.

yeah I actually get it. I'm a commercial diver. thats why the 150 lb.pressure test was a waste of money.

Hank Hill is creaming to this!

there is going to be a lot of calculations to be involved, like air pressure, balancing weight te rpm of the rotary blades, the steering like everyrhing needs a lot of research and calculating, i myself wanted to make one, but i dont have the skills to calculate all of this.

you can not use water as weight. If you take two balloons, and tie them together, one is full of air and you fill the other with water; it will still float, the same goes for a sub. Supplemental weight is required, and that weight must be more dense than water to compensate for the buoyancy of the displaced water.

So...the question I have is from welding class. They told us to never weld or cut on tanks that have ever held flammable materials -- there is a serious risk of explosion, even from just trace amounts of fuel or vapors. So how do you safely breach the tank? (Once you got it open with a large enough hole, you could then get in and clean it out. Thoroughly. Don't want fumes or fire while submerged.)

@spectre2466

Azendale one way would be to fill with water then cut with a torch. You could also flush with soapy water then refill with just water, it depends on how new or old the tank is. Propane has a shelf life of 10 years, after that it's not very flamable anymore but if it's a new tank or if your unsure the best thing to do would be to fill or flush with water and let it air dry for a couple of days before cutting. Personally I would rather buy the materials from a metal shop because you can get thicker metal. You still have to be a good welder to do any of this kind of work though, one small crack from a poor weld can make a sub leak like a screen door when submerged..

And the torpedo tubes well it depends on the torpedo you are using

It took 5000+ lbs to get our 500 gallon tank to sink. A sub that big would be impressive but unrealistic. You would have to come up with some way to transport it, which would prob be more difficult then the actual sub. But if you plan on making one let me know, i have several suggestions.
