- The building of a crucible forge.
The movie shows the building of a gas operated forced air crucible.
The forge can deliver very high temperatures due to shape, size and use of 2 forced air channels. The forge is build as a experiment but first tests where very promising.

Freerk, You my friend are the man! Love watching your videos, You are quite a craftsman!
Love the vids man, and what a beast of a forge! Bravo
Amazing build thanks for the great work
Right on time, i was looking for a good crucible prototype! Very good!
That was immensely interesting to watch! Very cool design.
I like the band saw with all the teeth missing.... love the vids and love that you don't make them into a 34 part mini-series...
sean tap I use them until they break or saw crooked. Sometimes I can be a little impatient and force it too much. Or try to cut unknown steel samples
I remember my first job in a machine shop I kept fiddling with the speed and lost a few teeth.. the foreman lost his shit and replaced the blade.. I was all damn it was still cutting fine.. But as soon as I heard the skipped teeth in this vid it took me back lmao
Excellent design and awesome workmanship. :-)
Excellent work
Awesome that's what you call a build man! Excellent video to boot!
He is a great engineer, and a artist.
Nice work!!!
Nice work!
Even the forge is a work of art!
Always inspiring.
Damn dude that is a nasty Inferno from hell ,looks like a turbo intake
Nice work
fantastic build
The ''pen'' gas tip idea was awesome :)
Nicely done! A small tip, use it or not as you wish. When threading internal threads on a lathe turned part leave it in the lathe and set the lathe into back gear and use a center in the tail stock to keep the tap in perfect alignment to the bore. Turn off the power on the lathe and turn the tap wrench by hand to start the thread. If the back gears aren't enough resistance to thread all the way down you can then remove the part from the lathe and finish in a vice and the threads will be perfectly straight and concentric to the bore.
Beautiful
Hey brother where did you get those frustom or cone section pipe fittings?
damn, he's got all the tools... merry christmas
Excellent!
Philip Dunn thanks! This thing is hot al hell.
É muito legal ver como são construídas as coisas, desde as ferramentas até as obras de arte saídas das mãos do artesão cuteleiro!!!! Nota 1000!!!!!! Parabéns
I love the way stretched sheet steel sings. Kinda of want to get some and twist and bend it and make a giant spring loaded wind chime.
Freerk I like your job.and that's what I like to be good job brother
Hi very nice work!!! Can you write the blower that you're using? And do you use propane gas?
9:30 oh that was scary haha. but yeah great video pretty badass
Attack of the Angry Welder demons lol
I gave this new welding torch with a sensitive trigger.
What is that mix used @1:11 in the video?
What size pipe is that going into the refractory burner? 1”? Sick build.
Nice planning and execution. Your Teflon tape was put on in the wrong direction that's why it was coming off as the fitting was going on. You might try "walking the cup" as you tig weld rather than free handing it. You are very blessed to have the material and a fab shop outfitted with the tools it has. Keep up the good work.
yes i noticed. thank you!
I remember Darksiders II.
Congratulations guy! You are a burnman.
Hello. Nice video and construction. Just one question... the pressure of the gas? Could you share that info? Thanks!!!
Parabéns pelo seu trabalho nota 10
Awesome channel! Really enjoy you just doing what you're going to do without the chatter. Well done!
It would help if you were giving information or instructions as you went , let alone a bill of materials?
Bravissimo
hi Freerk.. i came to your channel via Forged in Fire hehe,... good to see theres hope for us Dutchies too regarding knife and swordmaking!!... but i was wondering... .where do u get your supplies? like those pipenipples, fireproof insulation and all that stuff...
Hope to see a future crucible Wootz/ pattern welded Damascus San Mai knife
Damn man, always a pleasure to watch your videos! How many people in the building you work in? Is it like a co-operative work shop? Do you rent space there? I always here other people working in the background, I'm just a curious natured person.
this part is mine but the building is 2400 m2. we rent is with 7 parties.
I love this jop
that is boss would love to get a setup like this
Muito bom...muito bom mesmo!!!
Haha, you make Alec Steele's foundry look like some child's backyard project!
Very nice build video! Love the design!
Will it get hot enough to melt steel? If so, would you attempt to make some wootz steel for one of your blades?
hello Joe 925 of course it crossed my mind. All respect for Alec and his builds. My intentions are a bit different. I am first looking into casting and sculpting for eleborate sword handles.
I'm really looking forward to seeing what you can come up with with that foundry, elaborate handles sound very promising :DD
Btw, I didn't mean to disrespect alec or his work, I'm sure I couldn't do any better than him, I just wanted to highlight how much more evolved your design is in relation to his pretty basic one ;)
helojoe92 thanks! I understand. just saying.
Try to find comments about Alec Steele and I found this lol
holy shit them angle grinding techniques..
I'm sure you're right and I'm wrong but why did you go from the large diameter tube for the fan into the thin one? Seems like if you're using those squirrel cage fans, (high volume / low pressure) you'd want to keep the pipe large. Seems like if you were going to use that small pipe, you'd want to use air from a compressor (lower volume/high pressure)? I'd think the squirrel cages could only put a certain amount in, and the rest would be wasted potential, (the fan will turn at the same RPMs but it won't suck in any more air than it can push out). In fluid dynamics, when you cut the diameter of a pipe in half, you cut the volume by around four times. I bet you could test out my theory by turning on one fan (you'd have to block off the intake hole on the second fan while its off) and seeing how much air comes out inside the furnace, then when you turn on the second fan, I doubt it will add much more air, and I really doubt it would be double the air. Not trying to criticize, I'm a union boilermaker and work around this stuff, except some of our burners are so big, several of us can stand inside them at once.
I have built forges with one fan. This one Bruns considerably hotter. You are right that a bigger tube would be better but I had to work with what I can get for a reasonable price. I think a fluid narrowing exellerates the air flow also.
Also. When the forge burns high. It starts to suck in the air making it a hybrid.
Shane K lower diameter => higher flow velocity => higher flow rate
De nozel/las tip die je tot punt afdraaid (samen met de houder) is dat ivb met turbulentie in de mengkamer? en reduceer je die zo? anyway.. weer n leerzame video!
is this for making crucible steel???
rivercitymike76 first for bronze
Хорошая работа, привет из России!
Nice! But I wanted to ask, why not just get some AC fan motors so you don’t have to mess around with the DC power supplies?
i could not get them cheap
Twin turbo pizza oven...mmmmm pizza
twin turbo pizza incinerator
You was on FORGED IN FIRE? Is a tv competition
MUITO BOM PARABÉNS...............
what kind of temprature can you reach with this forge ? it look like more like a foundry than a forge. in any case amazing job Mr Wieringa has always :)
M. Pink yes it is. I have melted bronze with no effort at all. So 1200 easy. My guess is 1600. Have to do experiments with melting steel etcetera
ah sorry i didn't catch that, thank a lot for the answer. I hope see some crucible steel viking sword in a near futur ;).
M. Pink haha. I have mainly built it for casting bronze. But you know how it goes...
As it is probably 1800 deg C but if he changed gasses to something like acetylene 2400 Deg C with the forced air. to go higher you need induction or electric arc.
Some how some people are melting brass and copper in some foundry’s that are simply propane and seen some in charcoal I don’t see how mine gets super hot and will slowly melt brass but not copper maybe adding a blower will help. I have mine 2” of wool 1/2 Satanite with wool and firebrick on the bottom
Just wondering, but, have you ever considered doing more traditional style folded (or just fewer layers in your cut and weld style) swords? Or even more japanese style with different steel in different layers? Love your work dude, keep it up :)
i considered it but have other projects and loads of work to focus on now.
I believe that is called a foundry.
Freerk love your work but i just watched you put on silicon tape the wrong way 3 times (tip). Hold the threaded item in your Right hand place the tape at the top and turn your hand in a clock wise direction, works every time.....
Wheeler Shane yes I know. I Am a bit sick... Less focused
Tape goes in the direction your threading which is usually to the right or clockwise
Great work, but you forgot to stamp your mark on it!
lol. thought about it.
Good work you are a grafter mate do you think it would melt carbon steel ?
Woden Forge I don't know jet.... I built it I the first plase to melt bronze.
Thanks For the reply I can melt bronze one burner no air it takes a bit off time your one should melt steel easy 👍
I am curious why all the pipes are so long?
James Brettell for flow and optimum mixture.
You have so many vices, but never clamp anything when welding or grinding
IKR? Yet it's still bang-on precision made when it's done. Drives me nuts!
Freerk, man, seriously, it's time to build the Death Star and conquer the universe...
lol. sounds like allot of work. i would need minions.
I'm guessing you charged by the hour to build this ? It is way over complicated and the burner looks like its 600,000 btu for a furnace thats 100,000 nice work building it
Nice build but why do you need a lid that locks down on a crucible furnace? Thats the only part I thought was very unnecessary and a burden to use.
Not sure how much more welding SV Seeker needs, but if you've never heard of her, give it a search on here (RUclips) and check it out. The builders have people from all over the world go and help put the massive steel origami boat together in Doug's back yard. It'd be awesome to see you go and do some work on the Seeker. It's the /boat the internet built/.
are you making wootz by any chance?
maybe....
Can you made canisters Damascus.
kinda looks like brimley's ( dr. blair ) space craft from 1982 the thing movie. can i make a phone call.
Brian III love that movie. Maybe a subconscious connotation...
I like your videos very much but you have to think about some cutting speeds. For example the reamer way too fast and no oil it lasts not long, bandsaw tube cutting is the same. Some drilling is too fast some too slow and tapping is easier when you let the tap drill just grip for two or three rounds to get the right direction than it's easier to get it done by hand. Anyway I'm nagged around to much like I said I like your videos your workplace looks like mine always chaotic but productive keep up and Merry Christmas for you and your family
P. S. I think that pipe on the lid don't last very long
XJ9 thanks. No I guess it will not. Have to make a fire resistant concrete one.. Thanks for the tips. On the pillar drill I use the slow setting as it is a " band" transmission. Still looking to replace it with a gearbox one. I prefer not to use lubricant on some parts as it interferes with welding forging/chemical reactions...
Do you paint it ?
Dawid Urb yes. I have to do some more welding and testing. Then it gets painted with heat resistant paint
how come the forge dont just melt??
the wool isolates it, and the coating reflects the heat
Why 2 blowers for a small Crucible ? U only needed 1 awesome fab but it seems like crazy ass over kill lol
Jeremiah Meachum I built forges with one and I saw that it needed more airflow
Maximum airflow is crucial for higher temperatures if you wish to melt steel and other alloys. The higher the better!
Freerk Wieringa buy a bigger blower probably also cheaper on electric and take up a lot less space too LOL don't get me wrong I'm not trying to take away from your Fab work because I watch all your videos and you do awesome work I built my own forges and crucibles that's why I asked
yes that was a option, but i liked this design, never saw it and it givers allot of control.
Freerk Wieringa it's definitely a cool setup I do like it
Details your video
GREAT FABRICATOR but can't put the thread tape on the right direction ! lolol
9:34
IT'S LOOSE!
a plasma cutter would save you so much time with so many of your projects mate. they are pretty cheap these days too
Would not be half as cool though.
You could call this the "Turbo Forge"
But will it melt stuff. ???
yes it will. more will follow
I had no doubts. Any idea on the BTU output of that set up?
caleb terry no. I would have to jump into the books and also buy very high temperature measurement tools. It is pritty efficient I think. The coating helps allot. The chamber is well isolated and even at high gas pressure there is enough air flow to get a optimum combustion. But I am no expert on the science.

Arthur Texter my camera broke. It is at the repair shop. Hope to get it back soon. Thanks for the sponsorship!
🤘
If I had a dollar for the amount of times my welding gun has slid down and blinded me cause I wasn't paying attention I'd be rich enough to buy a copy of your shop. I laughed a little seeing your surprise.
CONNIPTIONS
Pravoooooo
ЭТО ЧТО? МАНГАЛ)))
Sigh, I suppose you never take it easy on yourself.
Not
i'll rather watch " Cast" Away / lol
I think you would have a lot more subscribers if you explained more about what your are doing, at each step.
Black Lives DO Matter!!! Yes. But I do not want to. Learning by doing is my learning method.
Perhaps he would or perhaps he wouldn't, some people prefer no commentary and videos are pretty self-explanatory. And while he does speak/understand English, you'd be surprised how many people don't, so having a commentary (even if subtitles were added later) would not only serve no purpose, but it would also show more detrimental. I can show videos like this one to my father and he'll probably enjoy watching it, but if there was some someone speaking a language he doesn't understand, he would probably be bothered by it. There is also the fact people talk over the sounds of machinery/forging, the sounds which are quite nice to listen for some of us and someone speaking would ruin them and serve as a distraction. If people don't understand what he's doing, they can ask in the comments, he replies to a lot of them.
No commentary also helps you focus on what is being shown, most things make sense if you give it some thought. It's harsh if you don't know much about forging and similar stuff, yes, but the frustration of not understanding may convince you to educate yourself on things you couldn't understand in the video.
If you can't understand by watching, you are in the wrong business.
I am definitely in the right business, which is not blacksmithing, and yet I can understand just by watching. However, a lot of people take up blacksmithing as a hobbie, and don't have a lot of formal education about it. I'm just giving him some advice about how to grow his channel. Here's a guy that does homemade PVC bows, and REALLY basic blacksmithing, way below the level of this channel: ruclips.net/user/BackyardBowyer Look at his subs, and compare them to this channel. Anyways, the man already replied to me, if he doesn't want to grow his channel, that's fine by me, I just don't see why all you other assholes have to chime in on this convo, which concerns none of you.
Other channels such as primitive technology do similar style videos where there is no speaking, however he adds some textual commentary as the closed captions, which people can just toggle
