Glad to see you back! I find your videos so relaxing. Blacksmithing is a truly beautiful trade/art.
This is how to make a video, everything I needed to know without some annoying dance club music playing over the top. Well done sir.
So wonderful to see you at work!
Thank you for letting us closer into your magical space. Many new ideas for us to tap into. You keep what you have by giving it away!. May you grow from strength to strength Sir.
Great to see another video, I find your work very interesting as it's compleatly different to what I do!
Thank you for sharing this. I love your setup as much as I love your workmanship!
Good to see you back. Hope to see more soon. Thanks for showing behind the scenes so to speak. :)
Great seeing the forge and learning more about the process. Thanks!
Thanks Torbjorn! Great to see the details of your forge. Quite the setup and quick to go to work...nice and efficient. Thanks again for sharing your passion with us. ~PJ
Thanks!
Thank you. You have given me some good ideas for the new shop...
Thanks for this video Torbjörn, this has given me some ideas for improving my own forge.
Great!
I always assumed you started your fire by staring intensely at it.
He he, think I have to level up for that :)
@@torbjornahman never seen coke before .. how does it not all burn up on the bench ?? guess that might be another question and answer video ..nice setup you have ,, keep up the great videos ..
@@randytravis3998 It needs a good deal of forced air to burn, so it will never spread from the "core".
@@torbjornahman ok thank you ..keep up the great videos .. love your work .you make it look easy .i know its not i have tried too bend steel a time or 2 lol .. Great videos ..
That's a cozy looking forge,great video!
Please Torbjörn more blacksmithing videos. I love them! Undoubtely there is something magical in this profession. Greets!
Thanks!
i agree with that lad, you should uppload lots more videos man, your exquisite
Boukovsky your profile picture is awesome.the old pig bearings logo.right on man!

Torbjorn... Awesome video! I have been waiting for this one. The retrctable hat on the chimney is genius.
Thanks so much for doing this video..
Shad
Thanks!
This is great! Love the hat on the exhaust!
Your films are addictive. Great job.
:) Thanks
amazingly thought out device. nothing extra! everything is beautiful and practical.
If ever come to Sweden, be sure to come to visit to admire your studio
I especially like your chimney cap. A good design for cold climates like ours.
Cool video. I made a coal forge, then I tried to buy coal. Not sold in California USA. Then I made a propane forge, best move ever! I use forced induction burners I made myself and used fire bricks from Lowes. I still use the coal forge with charcoal for bigger pieces that do not fit in the propane forge. I like your air baffle for control, I used a tee inline and made and adjustable cap on one end to bypass air or close to use all air.
Forge On!!
The horseshoe barn in Sacramento sells it, you just have to look for farrier supply stores.
you gave me some new ideas as i begin this new venture....great video
It's enjoyable to watch your videos...thanks for all your creations
Thanks Joe!
Hi, I just picked up an old forge, similar to yours more or less. Now to build the side draft. Looking forward to tinkering with it. Thanks for your excellent videos!
Please have this installed in my shop as soon as you can! :)
That is soooo cool, I love it. Thanks for linking me up!
Amazing...and thank you sir for demonstrating ur craft...we all wondered what tools were used for and what type of come u use for ur forge...that’s is what u soften steel with? U make such marvelous creations! Thank you sir for showing us ur mastery and how u make use of the tools to complete ur tasks! Be safe in these trying times! Best wishes to u and ur family.
Really nice set up! Hopefully some day I will put together a forge like that one. Great video!
Thanks! Good luck!
Ive seen a lot of forge arrays. From high-end, top-of-the-line, everything controlled by buttons and switches, down to a guy with a brake drum for a forge, a wooden box with some dowels and a few scrap pipes for a bellows and a railroad track for an anvil. Your setup seems to be my favorite so far, and i have no shame admitting its due in part to the "top hat" covering the chimney stack. I giggled like a child when then thing popped up
:) Great, thanks!
Great video and setup. I'm liking that retractable hat for your flue. I've only been using gas lately and I have been missing coal, this video really has me wanting to go back to coal or using charcoal. Thanks for showing us your setup.
Ok, great. Thanks.
Very similar to mine.
I had a hexagon-shaped piece of 3mm plate left over from a job and so used that for the forge bed base. It's about 28 inches across the corners and thus about 24" across the flats. I welded some pieces of 3mm plate as side 'cheeks' along four of the flats, to prevent the coal falling off the side. They're about 6 inches tall. The two remaining sides are positioned front and rear and left open. The front is where the work-piece is inserted and the rear is for long work that has to be fed through the fire and out the rear. I have made another piece that closes off this rear side if I don't need it open - for short work. In the centre is a cut out hole about 10" x 8" that accepts a firepot, also made from 10mm plate as your original. My up-draughting air tube is just 2" diameter however. The final tube is a stainless steel pipe with a threaded stainless pipe cap. The cap protrudes through the base of the firepot. My firepot is a little deeper than yours but the protruding cap makes up the difference. The pipe cap is of course drilled (5 holes) to allow the air blast. I have an almost identical ash dump, but no clinker-breaker.
I clean it out thoroughly about once a month, down to vacuum-cleaner standard. Get rid of all the ash build up which does conveniently fall below the level of the air cap onto the firepot base. There isn't a blemish on the firepot istself. It's scoured like new steel almost.
My fan is one of those used under a jacuzzi-type bathtub. I wired a 500W dimmer switch inline and use that to control the blast. There is an air gate as well. I find it very controllable.
Hood and flue is overhead but no fan involved. I have very good draw on the flue so no need for a fan.
I also start the main fire with a double handful of charcoal, although I use one scrunched-up piece of newspaper and a small pyramid of thin sticks to begin.
We love our fires. Thanks for showing yours.
Thanks for your forge description!
This is a great video. Lots of good information. Thank you.
Very good! Simple and efficient. Congratulations! I'll make one like, soon.
Well, energy-wise it's obviously quite inefficient. I'd bet no more than 3...5% of heat goes into treated materials at best (and this is optimistic assumption).
thank you for showing us your forge
brilliant forge man! i think i will make one for my new workshop! thanks for sharing.
Great!
Thanks for the look-see!
Really nice, i will be making a smaller one shortly & have just today done a deal on a anvil i spotted in a scrap yard £70.00 & it comes with a cast iron stand . can't wait to get started.
Wow, cool! Good luck!
Awesome! 3:20 is wonderful!
Funny you start your fire exactly as I do nice schop.btw like your blacksmithing.pat from Belgium ⚒️🔥⚒️
Excellent video .. I now have some great ideas ty forge on brother ..
Awesome video, this is very helpful. Are you running your forge off of Lava rock once your forge is lit with charcoal? Great work, thank you!!
Thanks. Might look like that... it's coke!
Very nice video. Keep on!
I'm glad your back on! I know you've been busy with your glass house. you've been missed!!!
thanks!
Glass house? Bong, pipe, bubbler :) Wohooooo :)))
***** Yes I have ben busy building a greenhouse. I'm not sure, I might upload a video on it....
+HASH funny guy? gumby fart!
Brady McPhail :) No, I'm not growing weed....
How could anyone not like this?
I love building fires for any use. You need a fire going, I'm your guy.
Where did you learn blacksmithing? You are a master, IMHO
Mostly by myself! Check out my short bio/about section on my web-page.
nice filming, great to see other forges. what did you think of my episode on 'Why Side blast Forges Are The Best'?
I know its all personnal prefference, but have you tried a side blast before?
Thanks. I like your forge videos very much. I have never tried side blast but you may have convinced me to try one out. As I mentioned before, they seem easier to maintain with coke. Only problem really is freezing temperatures... would you add antifreeze to the water?
My bosch has frozen a few times in winter but fireing the forge up thored it out no problem. I guess if it is completely frozen you could use antifreeze however it is a corrosive solt soltion and so you would need to have the tue and the bosch be made from stainless steel so it doesn't corrode away. I'm making some 'Super Tue irons' that are made from stainless steel soon. I'll keep you posted on them, I have a video publishing soon making a forge out of a BBQ using one.
What a great vid! 👍
Hi Torbjörn, that's a great setup you've got there! I'm in the process of moving my forge inside but i'm struggling to find a suitable flue. What size of flue so you use and is it stainless?
Tack för visningen av din ässja, nu vet jag hur jag ska hur jag ska modifiera eldstaden i min ässja till det bättre, proffsig
visning Torbjön
ok, va bra! Tack.
Damn I'm so jealous of this set-up. Can't wait to develop my own some day!
:) Great! Hope you get something going!
Have done it yet dan? Ime just starting, finished restoring my artillery forge today
@@gedhuffadine1873 Actually more into woodworking now, but still keen on metal work once I get the chance
I enjoy your work and can't wait to get a forge of my own going. I can' wait to see what you make next.
How much did the forge with your purchased tools cost?
Great! I haven't kept record of it all :) The forge, hood and flue alone probably have cost me $400-$500 in material.
Thanks for sharing
God I love to watch your videos. I seen you make a scythe blade and was wondering if you could make a video on making a lawnmower blade? Thank You
Great vid! You live in a cold country like I do. I've been daydreaming about installing my blower outside (love the quiet!). Do you think cold winter air cools the forge a little?
Don't think that matters much.
nice forge!
I like your set up..
Thanks,Torbjorn
Hi Torbjorn, I noticed your air valve is a choke valve, consider converting it to a bypass valve. A choke valve constrains the airflow putting strain on your blower (that, being a burner blower, is designed to flow freely). A bypass valve vents unneeded air in the environment, so that the blower always blows freely, while just the desired airflow goes to the tuyere.
I guess you're right, but it has held up for a long time now!
Fascinating to watch how other smiths start their forges and have them set up.
I've hear that some smiths prefer fire pots that are deeper than the one you have; does yours have any limitations that you can think of off the top of your head?
Not really. If you need a deeper fire you just stack fuel on top. Sure it could sometimes be nice to be able to get a longer heat, with a fire pot with multiple air holes in a row...
Thank you for sharing this
Great video! I'm designing my own forge now and this is giving me tons of ideas. What is your chimney made from? It looks like 12" (~300mm) galvanized ducting. I'm afraid of using galvanized ducting, but everything else is so expensive!
Thanks. Yes it's 12" galvanized duct pipe. There is no problem at all with my setup. The pipe does not get that hot... I can lay my hand on the pipe, say 2 feet up, during full blast and it wont hurt my hand. You need to heat galvanized above 900C for the zinc to vaporize.
Torbjörn Åhman Thanks! This is really helpful to know
Hi Torbjörn, how high is your chimney? I'm setting up my shop and I've decided to make side hood, same as yours. Here in Slovenia I can get 280 ad 315 mm pipes (closest to 12'') and standard lenght of 3 m per piece. Greetings.
Maks Šuc where I live in the US our chimneys are required to be at least one meter (one yard, technically, but who likes imperial measurements) above the peak of the house to ensure the smoke gets carried away by the wind before it has a chance to get sucked into the eaves
muledeerdude thanks. I'm still deciding whether to use galvanized pipe or stainless steel...but as one said before, anything apart from galvanized pipes is so expensive....also my shop is an annex to a larger building and I hope that a chimney higher than the large bulding won't be neccesary..
Maestro torbjorn
Thanks for sharing.
Excellent. Thank you.
amazing.
If I remember correct , I saw you were using gas too to heat the metal, which one do you prefer for what usage ? Great video for starting blacksmiting too tnx :)
A gas forge is good for even heats of larger stock. You can have multiple pieces in the fire at once without risking burning them. Coal is more versatile, but requires more control.... that's the basics.
Wonderful
Thanks for the view of your forge, dose the heat from the forge not burn of the galvanize coating on the chimney pipe?
Nope. Nowhere near that temperature surprisingly. I can safely hold my hand on the pipe a foot or two up from the box at full blast. It's 12" pipe and with more heat it manages to suck even more cold air so it never gets very hot, which is good!
I'll have to give that a try so, thanks again
I'm curious as I would like to mount the blower for my forge outside as well, how cold does it get where you are, I'm in eastern Canada and it can get as cold as -31C here I am wondering if you experience any issues in the winter at lower temperatures??
OK! Well, I haven't experienced any problems yet... touch wood. We usually doesn't get that cold weather. Around -20C is considered quite bad here.
Excellent
Mr.Ahman thank you for the informative video.I just have a quick question.Why did you feel the need to switch from the fire pot you have made to a cast iron one?
I want to make my own forge,but I cant find a cast fire pot anywhere so I will have to make my own by welding steel plates togather. would it pose a problem or not?
It will work fine! I switched to the cast one for the clinker breaker and the thick casting. If you weld from thick plate it will last very long, no problem.
Torbjörn Åhman Thank you!it helped a lot.
Very good.
Nice forge, what is that hose stuff you use from the fan to the forge called please mate?
That's some sort of aluminum foil ducting
Ok thanks.
How thick is the steel plate where the fire pot is resting on? Thanks for the amazing content!
Thanks! Not that thick, about 4mm, if I remember right, with some support underneath
Alright, Thanks!
Where can I buy the cast iron fire pot please,I like that very useful.
Check out www.angele-shop.com/shop/en/
hi thanks for showing your setup. i am really interested in the side draft hood. so if you have the time i would like to ask you what is the ratio of chimney diemeter, length and opening area. or if you can point me where i can get good info as i have seen many ideas on this subject but no hard data. thanks man. regards. pete
Check out the link in the video description or google "super sucker hood". I think one key point is to make the square opening slightly smaller than the area of the flue. This seems to make the entire front flange to act like a smoke shelf crating a vortex behind it.
thanks man i`ll check it.
Hello!
I have a coal forge from my grandfather in my garage, but no chimneys installed and the roof of the garage it's actually the home.
I'm a little scared about the monoxide carbone. How does your chimney suck such air and may you know about mountable ventilation systems??
Thank you!
I have a natural draft only! It's a 315mm pipe and it's about 4m high.
Nice I want to make a little coke or charcoal forge, have a propane one at the moment. But a coke one for back up would be good.
Yes, it's nice for small things and for isolated heats.
Yes true.
Yes mate, true, and I think you can welding heat better with the coke one also.
I have 2 questions:
- Fan supplying air to the grate has a variable speed (power) or not?
- Hood also has a fan (motor)? or is it just a long tube?
Thank you.
Mark Fisher. Ukraine.
No variable speed. I control the air flow with the gate/valve under the forge table. No extractor fan, just natural draft through the hood. The flue is about 4m high.
Thanks for the reply, Torbjörn. I wonder blacksmithing, so happy to watch your channel.
I want myself to try to forge the metal, but have not yet collected the necessary tools.
Mark.
Great, good luck!
:)
4m are enough, that's great and would reduce my costs - thanks for the advice :D
Hello . Here in Brazil we use charcoal because it is very difficult to find coal. So I'm with following doubts : Is it to a forge charcoal "Super Sucker -side draft hood" function normally pulling the smoke of this type of coal? Thank Luiz.
Yes, it should work the same.
Hola torbjorn. que diferencia hay entre las dos rejillas por donde sale el aire?
Not that much of a difference. One will let more air in.
Ok. Muchas gracias ! Esque quiero hacerme una fragua nueva con un ventilador extractor de caldera. Aver que tal me sale...
Ok, good luck! It will work fine I think.
Thanks
good forge
What would the purpose be for switching out the air grate with the other one?
The idea was to be able to control the size or shape of the fire, and to be able to replace if needed.
what would you recomend for an anvil stand
wood or metal?
id guess wood, i think it would absorb the hammering better unlike metal that may have the tendency to jump around ( i am no blacksmith tho)
I'm not sure. Some day I would like to build one in steel. A steel one is easier to fix to the floor, and takes less floor space I guess. Anything heavy is good, as usual... :)
The anvil stands that I've seen made from old stumps are always checked were the lag/bolts are and they just eventually just stop holding the anvil in place. Even if the stump was oiled down it will still check eventually. The stump would work great until you get the money to buy some steel to make a stand or just happen to find some steel some were. Most the times if you go to a place that's been logged off you can find drops or even mite be able to find a stump at a log yard.
Torbjörn Åhman allright tanks!
I've made two steel stands from 12mm plate, fully welded up into a hollow tapering box. Put the anvil on top, mark around the base, remove and weld 25mm square bar along the marks to retain the anvil from side slip. Obviously the front and rear has to be curved and shaped to suit the curve of the anvil base. Into this cavity, pour molten lead about 12mm thick. It cools and sets quickly of course. When done, lower the anvil back onto the lead topped stand. The lead cushions the anvil a little but it settles onto and into the lead in a few days. It also helps deaden the ring.
Hi!
What's the practical difference between air grates for your old fire pot?
The slotted one allows for more air flow?
Hard to tell. But in theory you could make one for small work that maybe only requires a single center hole and another for greater flow. I wanted to experiment!
What's the HP on that oil burner blower?
I have some questions: How often do you have your air gate/valve all the way open? What is it normally set at? Do you close it when there is no metal heating up in the coals? Basically, I just want to know the specifics on how you use your air gate.
Very enjoyable video, as always.
Fully open hardly ever, but that depends on how powerful your blower is. I guess half open when heating. Never close it completely when idle, at least not with coke which needs a bit of air to stay lit.
What is the material you use after the charcoal? it is mineral coal? And if it is, what can be used in case of lack of mineral coal? Thanks for the videos.
I use coke here, which is processed coal. Just use charcoal! It's the cleanest fuel there is, but it burns fast so you need large volumes.
Nice video,Torbjörn .
How do you do it when you have done your day's work.
Will you let your forge simply burn out or delete your you forge with anything?
Thanks. With coke I just turn the air off and let it be. Coke will not continue to burn without forced air flow. With coal I usually rake out the content of the firepot over a slightly larger area. That makes the coal less likely to stay lit for very long.
Aha, thanks for the answer
When I watched your latest video and saw the fire being sucked sideways into the side draw, I automatically assumed you had a extractor fan in the chimney to get such a powerful draw on your forge, but no - as I have seen in this video, it is natural = as you have such a powerful draw on your chimney, that is not easy observable with an open fire/a stove as the fire goes up. I live with my parents in a terraced Victorian house with 2 open fireplaces - master bedroom/lounge, and when there is a stormy wind blowing over the terrace (easterly/westerly wind) that the air is sucked up the chimneys causing a negative pressure in the house - that the wind is blown into the house through any holes/open windows/doors, especially through the ventilation fan in my bedroom, caused by the Venturi effect on the chimney pot. I assume you would have a similar effect if it was windy outside your workshop.
Yes, the key is a large straight pipe. Any bends will reduce the draft significantly
@@torbjornahman - the valve plate on the chimney is ingenious (🙄 - you wouldn’t be able to put a fan in it with the rod for the plate) and the fan sound that I could hear was the draft fan for the fire 😉
Hello from norway Torbjörn, i was wondering if you had any design/drawing or measurments for your self made fire pot ? im getting in to blacksmithing and my current fire pit/forge is way to big =P
Cool. That one is about 250x175mm where the sloping sides start, and 50mm deep roughly.
Thanks ;)
Please Torbjorn could you say where have you bought the new commercial cast iron fire pot?
Thank you so much.
Sorry I found a never used one at a yard sale more or less. You can find new ones at www.angele-shop.com/ but quite expensive...
Thank you so much Torbjorn
Is charcoal ok for forging and briquette head beads, hard to get coke here in Australia.
Lump charcoal is perfect. Avoid briquettes.
Ok thanks mate.
Hi buddy I have a question what capacity your blower has. I,m from baja sur México and I,m your follower thank you for sharing your knowledge and I like all your videos
I don't know actually, but you don't need a very large blower. I think the motor is at 90W or so.
ok thanks what happens I have a blower of 50 Cfm @ free air and it seems to me that my charcoal coke does not light well
Torbjörn Åhman you are a great blacksmith congratulatios
The CFM is not that relevant. The "Static Pressure" is far more important.
ok friend thank you very much for answering and I will look for a blower that I like. sent you greetings from Baja California sur México
Ça donne réellement envie !!!
Is that coke you burn? Does"nt look like soft coal...
Nice forge!👍
Greetings from Canada.
Yes, in this video (and many others) I use coke.
When would you use a slotted vs circular grate?
It doesn't matter really. I think I made the slots because I didn't have a larger drill.
Hi there, great to see your setup..I especially like your chimney hat...very clever. I'm in the process of designing a super sucker - would you mind telling me the dimensions of the main box? The opening looks pretty big but it clearly works. And the ducting on top - ate you running 300mm pipe? Thanks... Really enjoy your videos. I'm actually going to a craft fair withbsone blacksmiths soon here in Ireland and I'll be using a box of dirt forge inspired by your video.. it works a treat
Sorry...just read through the comments, say your comment about the flue pipe so that's that Q answered..
Sorry Torbjörn... I'm such a fool ..say the link for the super sucker plans.. thanks
www.anvilfire.com/21st-century-blacksmithing/plans/super-sucker/
What is the reason that make you change your firepot ? It didnt work well or was it too small ? I'm designing my second forge and i want to build a steeled fire pot like you did. Greetings from France!
First of all a cast iron pot will hold up much longer, maybe a lifetime. Then this one is a little bigger and has a clinker breaker which helps.
Okay thanks for the answer!
مبدع 😘
