- A look at the inside operation of a prototype fuigo (鞴) box bellows...two intake valves, two manifold valves, one piston, one output, double action...more about fuigo here: islandblacksmit...
valves: islandblacksmit...
fuigo archive: islandblacksmit...
four wooden flap valves (called ben / は弁), two for intake and two for the manifold, control the direction and location of the airflow on each stroke of the piston to provide double action to the single output into the fire...more about fuigo here:

I bet you choud make a killer katana
Domo arigato gozaimasta, Davej. m(__)m
I think I'm going to make one, I notice a huge difference in one main thing between old and new forging techniques, we have lost the quiet stillness and silence. My forge sounds like a jet engine starting up, It's nice to hear the crackling of the fire and hammer tinks, a much more relaxed environment to focus in. I'm going to build one myself, thanks.
there is something lovely about the meeting point of simplicity and efficiency...there's a bunch of traditional forge building info here: islandblacksmith.ca/2017/01/building-traditional-swordsmith-forge/
This is why I am subbed to you. Thank you for this video and the corresponding article on your website. You always put out top grade content. I can't wait to have room to build a forge and start bladesmithing with charcoal from my own coal kiln.
it doesn't take too much room, keep it small and see what you can do...check out this compact chisel maker's forge: www.geocities.co.jp/SweetHome-Ivory/2387/Kikigaki/Nomi.htm
Sooooooo very cool!
...i wanna see someone make a plexiglass-walled fuigo with internal streamers for demos, hours of fun to watch...i was surprised to see that without a tuyere pipe the airflow clearly comes out diagonally alternating towards the front or back depending on which direction the piston is moving...the grass shows it a little bit at 1:34
It's magic!
hello dave can you explain how the charcoal bed is not burning?,
if you use a charcoal bed, keep it damp before lighting the forge....also helps to have it all at that certain size, and softwood not hardwood charcoal: islandblacksmith.ca/2017/01/building-traditional-swordsmith-forge/
Всё гениальное просто!
Hey im making my fuigo right now, i just have a question if you dont mind. When you put it next to the hot coals what stops the ventilation flap from burning? I feel like it will catch fire or something. How close to you have it?
the fuigo sits behind a protective wall and has a steel pipe connecting it to the tuyere so it is nowhere near the hot coals...plenty of info on this playlist, check the descriptions for links too: ua-cam.com/video/CiSxI4wKpds/v-deo.html
Thank you for that visual explanation
I am going to do Yaki Ire on a very thin blade( about 1mm) do you think it will work?
could it work? yes. will it work? dozens of variables to consider...but it will be challenging, might take a few tries...
I think it would be cool to do a demonstration with smoke somehow to see the movement of air
yes, two different colours of smoke would be very informative...
Your cinematography is so good. I hope someday you Make more videos, or make them available for purchase.
I love the way you describe things, and your video is always so well crafted... like everything you do!
I've often wondered how this works exactly!
The only thing missing is some mixed in shamisen in time to the clacking of the valves!
that would be lovely, need some live accompaniment to forge to...
You are right. Explanation is awesome.
I've gone blank on who it was, but I believe it was a friend of yours, that made the collapsible/take-down fuigo. I'm going to have to find the video again because I still really want to make one to take to blacksmithing events. This video made me think that it'd be cool to have clear tops so people can see how it works (or maybe even make a full one out of plexi some day.
Its good...👍👍👍
Its good...👍👍👍
Awesome explanation.
What is that thing which is wrapped on piston.
thanks. i was actually wondering how it works :)
quite an interesting system!
Muito bom
Bacana demais 👍😍👏👏👏👏👏
It's so simple and easy to make. Very interesting !
How do you keep the embers and coal from being sucked back into the blow hole? And what is the wool or cotton material? I have more research to do. Looks great thank you.
there's never any suction, it is blowing out on the push and pull stroke...the valves only go one way...usual piston gasket is raccoon fur, this is an old sheepskin rug, carpet apparently works too...more info and links here: islandblacksmith.ca/2015/06/why-you-need-a-swordsmiths-fuigo-box-bellows/
@@islandblacksmith thank you very much
Just changed my valves from rubber to wood so I can get that beautiful fuigo sound :)
great! did you find the article on valves? islandblacksmith.ca/2015/11/making-valves-for-fuigo-box-bellows/
I'm new to blacksmithing and I'm just 15 so I don't have much experience so do you have any tips for me. Other than that what other things that you can get some high carbon steel from. Any help would be useful. Thanks.
there are several hours of video on my channel and many detailed articles and photos on the website, if you study carefully you will have a good foundation to build on! old files are a great source of steel to practice and make great knives from...

@@islandblacksmith Thanks for the info but one more thing. How much charcoal ( I'm using softwood pine) do I need for forging a blade ( shaping it to tempering) ?
pine is a great charcoal wood! plenty...depends on the quality of the charcoal, the skill of your charcoal chopping, the construction of your forge, if you use fuigo or something else, how well you forge, and how many blades you need to make to get one that survives...keep track of the weight and see how it improves as you go...
@@islandblacksmith Another thing.When you are about to quench, what colour of a steel are you looking for and how do you know you are at the right temps?
there is a vast amount of information on the website for those who diligently search...quenching is called yaki-ire...until you get started and work away at it you will not know the right questions to ask or how to understand and apply the answers...keep at it, the journey is long and few survive the resistance of real materials! ^____^
That is great! I think that having a small fuigo would be great to carry around to demos and let people see how it works
it is pretty fascinating to watch and much easier than explaining to folks...
I build mine according to the Japanese box bellows design. It works fantastically with a good airflow, and has allowed me to bypass noisy electric blowers. The main thing with box bellows is that it is sealed properly ( I used a wax on poly after sanding the insides ) and the main box in which the piston slides is squared up correctly. A carpenters square helped out. I also angled the handle in a similar way to the one pictured in the video. I found it more comfortable on my wrist that way.
great!
Excelente ,.seque o padrão japonês
What are you planning to do next ?
Thanks a lot for information.
Muito bom
👍😍👏👏👏👏👏
you're alive :D nice
+++++!
Incredible!
Nice fuigo
just a simple prototype, but it actually works very well!
Very interesting!
I love your videos and your shop. Keep up the great work. Love it.
it is a nice down-to-earth place to be and to work in!
Wow!!!!!
Dave, would you recommend I build my own fuigo box bellows or purchase one to start?
depends on your carpentry skills! this one is pretty rough and works just fine for normal forging work, see what you can come up with! ...the only options for purchase are to find an antique online from japan (beware of the small travelling tinker's size though ~60cm) or convince gabe to build you one, i have been encouraging him to begin making them available for purchase... granitemountainwoodcraft.com/category/fuigo/
Crossed Heart Forge - islandblacksmith there's a large art studio in Lethbridge (CASA) that has a pretty well equipped woodworking shop. They allow artists to come use their equipment for a small fee. Maybe I should try building one using their studio. that'd make an interesting video series...
i am sure you can do it, i built this very rough one from scrap cedar with a handsaw, chisel, and kanna...
Is this what I saw as a kid? 风箱？
yes, very similar, box bellows are fuigo or fukisashi in japan: 鞴 ...the structural differences are a single rather than double piston rod, and the manifold is on the side and has two additional valves instead of on the bottom with a single valve:

鞴 www.google.com/search?safe=active&q=%E9%9E%B4&tbm=isch
Well. This is more simple than I though
interesting isn't it!
@@islandblacksmith yes so fascinating, but may ask how the katana get the flat ji and those angle ji (shinogi ji) I mean no way they just hammer it right, the line is just to perfect I'm so confuse
yes, by hammering...it takes years of experience and many hours of careful work to forge within 1mm of the finished shape...here is an example: instagram.com/p/BQRs6WRAIbo/
Constant air flow
pretty close isn't it! relatively simple technology but works so well for its intended purpose!
Crossed Heart Forge - islandblacksmith some of the most efficient things are the simplest design and most of the time new tech is just a improvement on a old idea.
indeed!
