Personally, I Think Your Video is the Best and Most Detailed of any I,ve seen on makeing a Fire Piston. Thanks for showing people this Life Saveing Skill.
Great video! It shows what can be done with minimal tools and creative thinking. Sometimes you have to make do with what is at hand. That is what survival is all about. I would pick this guy to be on my team any day.
this is the only good video ive found on how to make one without having access to a bunch of fancy tools. It sure beats buying one. thanks for posting!
You might try the freeze plug method. go ahead and chamfer one end of plug. Put the plug in the freezer for an hour or so. The plug will shrink several thousandths of an inch. Wearing a glove heat up the end of the pipe with a lighter. heat it right next to the freezer have a table ready. In a fluid quick motion pull the plug out of freezer set it on table sanded side up and quickly push the hot pipe down on plug. You have a fraction of a second to push. They will be locked together tight.
Nice! Manufacturing tips: 1: Cut enough rod for both the piston and plug. Place the intended plug end in the drill and sand. This sands the piston evenly and includes the very end of the plug. Once sanded, cut the plug away. 2. Extra care when ramming the plug. Aluminum tube is soft and may split. 3. Two "O" rings spaced no more than 1/8 inch apart and a touch of white grease makes better seal/higher compression/higher temp. 4. Follow's Nick's notations for safer tooling of the parts.
Nick, regardless of all the things you had to disclaim,I think the project showing how to accomplish your task while using tools at hand was an excellent example of ingenuity.. Of course that is my opinion, so speaking for me, Good Job!..
I thought I posted a comment on this. Great video. I actually used your method to build my own piston. Something like 20 pistons later and still having fun with them! I just finished another one tonight!
I have seen many videos about fire pistons, but is the first time that i see a explication so detail...thank you and congratulations. I suscribe to your chanel...
Was waiting for the annotation to pop up ... "Don't use the needle like I did" lol This is a cool video, making use of what you have to make a very useful item .. well done!
@AlexKessler99 I put char cloth in the fire piston. Friction is what causes the char cloth to ignite. When air is compressed really fast, all the air molecules collide with each other. The result is that there is a lot of friction between the molecules, and it causes the air in the fire piston to rise to an extreme temperature. The air gets hot enough to ignite the char cloth.
Other than a few safety issues( i'm sure others have pointed them out to you) you did one hellova job. You ought to sell some of those . Again just a fantastic job. I'm very impressed.
I don't know if anyone's shared this with you already, but if you need to make another fire piston, once you cut the plug to seal the end of the tube, you'll probably have an easier time fitting the plug if you put the plug in the freezer overnight. Let it sit for a day after you've hammered the plug flush to allow it to expand back to it's normal diameter, and to allow any condensation that may form to evaporate,
Really interesting video. I had to google fire piston, since I could not determine the purpose of the tool you were making, even by the end of your video. I will be making one of these in my workshop for certain. A couple of suggestions if you ever decide to remake the video: If available, use a drill press to chuck the rod into when sanding to desired thickness, and to drill the tinder hole. Also, using a block of wood to elevate the hacksaw blade to the desired height for cutting the groove.
This is a well detailed explanation on how to make a fire piston, you inspired me to make one myself which I'm nearly finished. Just one question, is it hard to saw that solid non-hollow aluminum rod? I was thinking of using a hack saw for that job. I just need to make the plug and I may need a drill seeing that sanding down an aluminum rod would be difficult without one. With mine I'm able to burst a hole into duct tape when I try using it as a plug, that makes mine seem promising.
@vaxcave I bought a hammer a while back. Thanks for the advice with the file. I realize that probably wasn't the smartest thing to be doing with a file.
Hey, great vid....one suggestion, you should cut another groove and add another O ring, the compression will greatly increase and you should get a more complete ignition of the char cloth.....hope it helps!!
Pretty cool man. One thats cheap to build and reusable potentially... forever! Not cheaply made out of plastic or somesuch nonsense to crack or break after repeated use. Good job Nick!
@mach352 Thanks for the advice. I think silicon caulk would work slightly better than nail polish. It is more rubbery, and wouldn't be so stiff. Thanks!
Yes... but I would probably try to find a thicker o-ring... or be very careful not to go too far with the groove... but things can go wrong, and tinkers have to tinker more ! Looks like a fun little project... probably would help to have a work bench, vice, drill press... the ultimate man-cave!
Good vid bro, you really covered the bases. Just be careful smackin stuff with a file, their hardening process makes them strong but extremely brittle.
This is a really well done vidio! and anouther way i've heard of fixing a o ring grove that is to deep is to just put some cheap nail polish in the groove, i couldn't get tape to work but i geuse you did.
What's the best way to transfer the ember to the tinder? Is it best to put the tinder nest on top of the ember while it's still in the piston, or try to knock the ember into the tinder nest? Also, great vid!
@DarxusC I have no problems with o-rings and durability. Let me know how that works out for you. I imagine it would be really hard to get a tight enough seal without an o-ring. Good luck,
this video was very informative and help ful when i was making my own thanks i just have one question could you substitue the o-ring for something else?
@DarxusC Think the main reason for o-ring rather then close tolerances is that you can remove or tweak them so the piston can be pushed in for storage without compression.
You can start a fire with it. It is good because you can use things found in nature to start fires, like tinder fungus, punk wood, etc. A lighter can break, or run out of fuel. A fire piston can start a fire and won't ever run out of fuel.
Great job. I'm a machinist, but I love the minimalist approach. Yeah, you did everything wrong as far as safety, but I've seen professionals do FAR worse. Rad project. I'm gonna make one. Thanks.
To make char cloth get a small container and drill a small hole on the top. And lay something like 100% cotton inside or 100% linen inside, the size doesn't really matter just make sure it's not too small as it will shrink. Then heat it in a fire or something, smoke will come out of the hole eventualy, and as soon as the smoke is gone take it out. It's really easy, and the stuff works great.
Little suggestion from other vids I've watched. Use char chord instead of char cloth. Get 100% cotton clothes line from the dollar store. Cool it up in an Altoids can. Heat it with Sterno or something till its charred. Works much better and makes enough to last years. Hope this helps.
Dude it would be really helpful if you put outside dimensions and inside dimensions along with parts list in your description. This is an awesome starter I would encourage you to be more specific.
i totally agree it is pretty awesome more novelty then anything relay, but a bic lighter could last months especially if your using it sparingly, and you can bu a whole pack of lighters for half the price of the materials to make the piston
@LLuE88 Sorry, I don't remember what size the o rings were. I just took the aluminum rod over to the o rings and matched them up with each other. I found an o ring that was about the same size as the rod, and I made sure it would be small enough to fit in to the hollow cylinder.
@WARLORDVONDOOM Probably not. In my experience, you have to air dry wet char cloth, or else it won't ignite. I have tried to ignite slightly damp char cloth, and have never had success, no matter how many times I compress it.
good video kid... ive been thinking of making one for a while and your video is well detailed. so i should have a decent little aluminum fire pistion by the end of today.
Hey I went out and made one of these.The rod fit inside without sanding, perfect less work! got the "O" ring to fit drilled my indent and tried it...... I'm having trouble getting it to ignite char cloth any suggestions? Thanks again for a clear video.
@dannisan77 It takes a little effort to cut through the solid rod. If you have a dremmel or some other power tool it might be a little easier. It took me about ten minutes to cut through the solid rod, but that was probably because I didn't have my hack saw handy. I was just holding the blade. (could be dangerous)
@cougarbahia Nova Scotia? Wow, how much would shipping be from Arizona to Nova Scotia? I would charge about $10 USD plus whatever shipping would be... But unfortunately, I don't have any extra time to make fire pistons right now. I am a full time student and I also work full time.
Thought the VIDEO was AWESOME! great little tutorial... and Yes I agree that the drill thing was stupid as hell, and no one else should do that... But you did say that in the comments and then added it to the video. Thanks for the solid vid, I really appreciate it!
I never said this was the best survival tool. This video was made to show those who are already interested in fire pistons how to make one. If you make a fire piston right now, and then put it in your survival kit, then you can use punk wood, or tinder fungus that you find in the bush. You don't need to use char cloth. A fire piston will never run out like lighter or matches.
For all the people saying you were using all the wrong tools fuck them! You improvised and overcame and that alone is awesome! Not only that but you actually made a 100% working fire piston! Keep it up dude!
Nice, I've been wondering how hard it would be to make something very similarly without the O-ring, so it's more durable. Just sand the piston down to a more snug fit in the cylinder.
its really cool how it works and all but instead of going through all that work buying the rods and tools. why wouldn't i just bring a lighter/matches. you can say it can get wet but so can the char cloth. your not going to have those tools and materials in a survival situation and if you did why wouldn't bring a lighter or matches to begin with and save yourself some time??? just a question
Hey ... I have the exacte same problem - I think its due to the fact that the rod does not create a tight eneough seel , though the O ring should do it - I have a double O ring on mine but I still have problems.... sigh...! If you figure it out - Let me know, ok ?
Hey Dude great vid I like the way you improvised with your tools many times in my life I needed a tool and just improvised. This day and age kids wear helmets to play in the backyard, we need a little danger :-)
@sunderwood52 First off, I myself have never been able to get cotton to work in a fire piston, it will just blacken and smell burned, but no coal. It does take some practice to be able to get it to work with char cloth. The first time I made a fire piston, I thought it must have been a dud, cause I couldn't get it to work at all. Turns out, I just needed to practice using it. You almost have to put your whole body weight into it and push it into the ground to get it to work.
Every piston has at least two opportunities to create a good O-ring groove...two ends. If you wait until you get the groove just right before you cut the rod length you have nearly unlimited opportunities to get the groove right. When it's just right, cut the rod to length.
Keep trying. Longer works better. They are also sold in some science supply companies. I worked on a plastic one that didn't work so I understand the frustration.
Try this. Get some safety goggles and leather gloves, take a D shaped file like that, and try to break it. If you manage to get it done with anything like TWICE the amount of force he was using, you might begin to have a point. (pardon the pun) I also notice that in 06:30 or so, the drill is pulling the saw teeth instead of pushing: If there's a catch, it will pull the saw through your hand the wrong way to do much cutting. Pretty clever, actually!
Nice video, Don't apologize for your tools or technique. You did fine. If you have access to a good local "not for profit" technical college, then I would say you would do well to take their precision machine tool classes. You would do well as a tool and die maker. (my trade)
@TheDylanMetz I live in Arizona. I was living in an apartment when I filmed this. I'm probably not going to have any time to make fire pistons for other people right now. Sorry.
Well for next time here is a little trick for getting the o-ring off without any tools. You grasp the o-ring on both sides and pinch upwards, when you do this it will form a little bubble or hoop at the top and you can just roll it off with your other hand.
Actually, heat IS particle movement. The compression of the air has a higher ratio of movement to volume, creating a higher temperature. You end up having the same amount of thermal energy in a smaller volume.
Do you have any videos on first aid? A rock would have been better than using the file,as a hammer, for instance. Files are brittle, and when they break they are quite sharp. Also, holding the hacksaw blade the way you were risks a very nasty cut if the blade catches in the work. Great idea for the product, but bad example on how to use simple tools.
Personally, I Think Your Video is the Best and Most Detailed of any I,ve seen on makeing a Fire Piston. Thanks for showing people this Life Saveing Skill.

I've never heard of a fire piston. But, I wiki'd it and it goes back to ancient times. Very cool. "I learned something here today". Thank you.
I appreciate that you showed your mistakes, and how to fix them.
Nicely done. I'm going to add this to our list of scout projects. Thanks!
Was waiting for the annotation to pop up ... "Don't use the needle like I did" lol This is a cool video, making use of what you have to make a very useful item .. well done!

Let it sit for a day after you've hammered the plug flush to allow it to expand back to it's normal diameter, and to allow any condensation that may form to evaporate,
To seal the end of tube, instead of reducing the rod, and option might be to heat the piston with a propane torch so that it expands.

You are a craftsman. Great process you figured out here. I'd buy one.
Excellent use of tools in my opinion. That is one nice looking fire piston.
Hey, great vid....one suggestion, you should cut another groove and add another O ring, the compression will greatly increase and you should get a more complete ignition of the char cloth.....hope it helps!!
Enjoyed the whole movie. Great little project just the thing for a wet afternoon.
yes you can, i've seen some made out of wood. real beautiful. Not sure if the inside was lined with metal or not.
Pretty cool man. One thats cheap to build and reusable potentially... forever! Not cheaply made out of plastic or somesuch nonsense to crack or break after repeated use. Good job Nick!
Excellent video!
I'm going to try to make one, and use my drill press like a vertical lathe, to machine the parts.
Thanks so much for the great idea!
I recorded one last Time (ariana grande cover) today can you watch it and reply to me now? 😃👍
Excellent design and so small! Thanks for sharing. Nice safety comments - it worked for you but some are not so careful.
Very clever though. You could mill a lot of things from aluminum with a drill if you really had to.
Nicely done! Very ingenious and practical. Good tip on the fix by using the tape.
@mach352 Thanks for the advice. I think silicon caulk would work slightly better than nail polish. It is more rubbery, and wouldn't be so stiff. Thanks!
use a pin or needle, or even the tip of your knife to transfer the ember to your tinder bundle.
I think I am going to try that little project. I have always wanted one of those but didn't want to pay the horrendous price for one.
Very cool. Thanks for posting. Have you tried starting with a rod and tube the will slide together?
Yes... but I would probably try to find a thicker o-ring... or be very careful not to go too far with the groove... but things can go wrong, and tinkers have to tinker more !
Looks like a fun little project... probably would help to have a work bench, vice, drill press... the ultimate man-cave!

Wow, thats was truly incredible, (with your lack of tools, work area, & limited skill) You still managed to make a first rate piston. well done!
You can start a fire with it. It is good because you can use things found in nature to start fires, like tinder fungus, punk wood, etc. A lighter can break, or run out of fuel. A fire piston can start a fire and won't ever run out of fuel.
well done, thanks bro.
Loved your method of sanding down the center rod! :D
Great job. I'm a machinist, but I love the minimalist approach. Yeah, you did everything wrong as far as safety, but I've seen professionals do FAR worse. Rad project. I'm gonna make one. Thanks.
A FIRE PISTON ignition is the same principle that a Diesel engine ignites fuel with. Great video! 😀👍
I wonder how many of the safety experts here have actually accomplished a tenth of what you did. So many do-nothing critics.
I recorded one last Time (ariana grande cover) today can you watch it and reply to me now? 😃👍
Thanks for the video.
Even you made a mistake.
You showed how to fix it.
So it was not a mistake it was
Another lesson .

Hey to fix the compression problem you can just cut a second groove for another o ring.thanks for the tutorial, helped me to save 200 dollars.
That's a cool design. I always see them like 12-15" long.
@LLuE88 Sorry, I don't remember what size the o rings were. I just took the aluminum rod over to the o rings and matched them up with each other. I found an o ring that was about the same size as the rod, and I made sure it would be small enough to fit in to the hollow cylinder.

this video are awesome. i have a question, where did you find the o rings? can you find those at the home depot? and whats the size? thank you
im sure when you were at homedepo you should have decided to get a proper pick set to get the o ring off and a proper lath to sand the rod down
Thought the VIDEO was AWESOME! great little tutorial... and Yes I agree that the drill thing was stupid as hell, and no one else should do that... But you did say that in the comments and then added it to the video. Thanks for the solid vid, I really appreciate it!

You gave me just a task for my christmas holidays :)
That was way cool, brother. Now I gotta go make one.
great video. Done really well on the fire piston !!!!
i am amazed this worked with aluminum
@sunderwood52 First off, I myself have never been able to get cotton to work in a fire piston, it will just blacken and smell burned, but no coal. It does take some practice to be able to get it to work with char cloth. The first time I made a fire piston, I thought it must have been a dud, cause I couldn't get it to work at all. Turns out, I just needed to practice using it. You almost have to put your whole body weight into it and push it into the ground to get it to work.
Where are you located. Your apartment lot looks familiar. Cool vid to man.
Good video defently going to try this an it's good that you show how to fix mistakes
Every piston has at least two opportunities to create a good O-ring groove...two ends. If you wait until you get the groove just right before you cut the rod length you have nearly unlimited opportunities to get the groove right. When it's just right, cut the rod to length.
Fiddly but very effective. Love it.
Hows your Finger after putting it on top of the Tinder at 11:56? I even saw a little smoke from the burning of your finger, lol. Great vid though.
Keep trying. Longer works better. They are also sold in some science supply companies. I worked on a plastic one that didn't work so I understand the frustration.
Great video man. I'll be trying this on the weekend.
Would Aluminum or Carbon Fiber Arrow Shafts work also ? You can get these anywhere they sell Bowhunting equip. i Think some are Hollow.
thank you I've been looking to make one of these and this is the easiest thanks
Dude this is a great video. I'm going to make one this weekend! Thanks!
Try this. Get some safety goggles and leather gloves, take a D shaped file like that, and try to break it. If you manage to get it done with anything like TWICE the amount of force he was using, you might begin to have a point. (pardon the pun) I also notice that in 06:30 or so, the drill is pulling the saw teeth instead of pushing: If there's a catch, it will pull the saw through your hand the wrong way to do much cutting. Pretty clever, actually!
Nice video,
Don't apologize for your tools or technique. You did fine. If you have access to a good local "not for profit" technical college, then I would say you would do well to take their precision machine tool classes. You would do well as a tool and die maker. (my trade)
I'd buy a few O-rings with different sizes and try to match an O-ring with the groove not the other way around.
COOL!!! im gonna make one, wish i still had a metal lathe would make it easier
It is a Gerber Paraframe.
how does this work mind blown
@TheDylanMetz I live in Arizona. I was living in an apartment when I filmed this. I'm probably not going to have any time to make fire pistons for other people right now. Sorry.
Just cut another groove next to it. There, compression problem fixed.
Cool stuff. Never seen that done before.
How much time does it take to sand the rod?
Well for next time here is a little trick for getting the o-ring off without any tools. You grasp the o-ring on both sides and pinch upwards, when you do this it will form a little bubble or hoop at the top and you can just roll it off with your other hand.
Actually, heat IS particle movement. The compression of the air has a higher ratio of movement to volume, creating a higher temperature. You end up having the same amount of thermal energy in a smaller volume.
You're great man this video is very educative !!
You just blew my mind, sir
Do you have any videos on first aid? A rock would have been better than using the file,as a hammer, for instance. Files are brittle, and when they break they are quite sharp. Also, holding the hacksaw blade the way you were risks a very nasty cut if the blade catches in the work. Great idea for the product, but bad example on how to use simple tools.
