Great work indeed! I wonder what type of insulation brick/material you have used and what is their cost? This looks the same material that we see in commercial furnaces.
This is probably the best oven made on UA-cam and he did it all with such crude tools the one thing I will say is it is also probably expensive that ceramic fiber board is $100 the bricks are at least $6 each idk the price on the ceramic felt but probably not cheep then the electrical ads up when u want to do a good job like he did with I intend to build one but for annealing glass the ovens happen to be very similar and I want to make it this well
One of the best builds I have seen. But one request can you do another video going through the electronic side of it that would be great. You have inspired a lot of people with this one. Well done and good luck.
Hi, I saw your knives in Facebook, they look impressive. Som look like Muela. May I ask you what kind of tape you use in the label printer to etch your knives? Tnx!
Great work. Very nice construction and quality electrical work. What was the thin sheets you put between the fire brick and the steel plates/frame work? Thanks for sharing.
Excellent build buddy, thanks a mil for posting this, could you please tell me where you got your bricks and controller from? I am in Europe and can only find the bricks in UK
gavo1958 Look for "TAOW electric foundry" he's got eBay links and documentation on his materials, you might find something useful. He's also telling about his development process, so you can get a lot of inspiration designing your own oven.
bom dia amigo, será que você poderia me passar a bitola do fio kanthal e o comprimento que usou e valor de resistência ohms, muito bom seu vídeo parabéns pela dedicação.
It's a K23 lightweight insulating fire brick, which is resistant up to 2300°F (1260°C). There's also K26 firebricks, which take it up a notch to 2600°F (1427°C).
that sure looks like a professional job to me... is this your trade?... and can anyone tell me what the best method of terminating the resistance wire, and connecting to power and ground would be?.... i see one video on space heater elements using "bolts" somehow welded (no doubt very high temp solder) to nicrome elements, but with heat activated limit switches to prevent over heating in that application. In that only video there is no mention as to what type of material the bolts are made of or what the welding method is... much less if it would be adequate for an electric foundry or heat treat oven running at much higher temps. what is the best way to hook up that element safely?... i see in your video you wrapped the ends three times and twisted it together.. do you just twist tie and solder a specific gage of wire to that end? please forgive me if seems like a dumb question... just seems like there may be a common and best way to do it; that would be very good to know. Thanks for posting this video Tritt.... it is a beautiful work in itself.. thank you for investing in the future by passing along a good example.
Hi Tritt, nice JOB!How about your chamber size, how did you calcolate the kanthal wire, and also how about increasing timing to arrive at 1050°? I'm looking to build one like your, please if you have just one minute. Thanks in advance
Kanthal a1 wire. 1mm² 1500w worth of it. Kiln pid controller from ebay. Steel. Grade 23 bricks. Vitcas (google search them) they have bricks for 2 euros a brick. Also. Use ceramic fibre as a outside insulation. Much better and lighter than another layer of bricks.
Děkuji. Použil jsem to to relé: KSA225AC8 Ovládací napětí: 100..240V Trvalý spínaný proud: 25A Špičkový spínaný proud: 250A Jmenovité napětí zátěže: 250V AC Špičkové spínané napětí: 600V
Kanthal a1 has a specific ohm (resistance) per meter. You can often get hold of the information on the manufacturers website. If you are on a 230 grid. It is as easy as you calculate how much power you want. Lets say 2500 watts for a chamber size of 15x15x45 cm. Lets say you are using a kanthal wire sized 1.2 mm² with a specific ohm per meter of 1.5 to make it easy. R=U²(voltage) over P (power watt) = 21.16 ohms. 21.16 ÷ 1.5 = 14.1 meters of 1.2mm wire. THIS IS NOT A SOLUTION NOR A REAL LIFE SCENARIO. THESE ARE MADE UP NUMBERS
What are the dimensions on the kiln volume-wise? How much watt do you use? What thickness kanthal wire did you use? Im calculating a kiln, the book im reading has a chart, it says i need about 3500 watt per cubic feet. The design: 15 amp * 230 = 3450 watt. K23 brick is 230mmx114mmx64mm. A foot is 302,5mm. If you put the K23 brick on its side, and each brick has on one side a brick that it connects to, that leaves an area of 166x166 mm. A square foot is 302,5x302,5mm. 1/(166^2/302.5^2)=3.32 feet high a kiln for 15 amps. 302,5*(1/(166^2/302.5^2))=1004,5 mm high. A brick is 1004,5/114=8.81 bricks high. So if you take it 9 bricks high. Its 4*9=36 bricks for the walls. R=V/A= 230/15=15,33 ohm. So now you need Kanthal wire, 15,33 ohm total to get the 3450watt drawn at the wallsocket, so you wont get more than 15amps and stay below 16 amps so the fuse wont blow. You can devide it in sections that add up to 15.33 ohm in total. So if you were to make the kiln in 3 sections each 3 blocks high, the unit needs to be 15,33/3=5,11 ohm each section. You can make 4 heating sides, that will get you 5,11/4= 1,28 ohm each. To get the right size wire you need to choose which wiresize will fit the side, remember the bigger the diameter the longer it lasts. Taking 1,5mm 0,764 ohm/m will get you 1,28/0,764=1,68m per side; 1,2mm 1,19ohm/m will get you 1,28/1,19=1,08m per side; 1mm 1,72ohm/m will get you 1,28/1,72= 0,74m per side. Of course you still need to coil the wire around some round (wooden)bar and then make some turns , remember it has to fit in between 166mm and 3*114mm and still have some room for edges an some "meat" to hold the coils in. How you configure from there is for you (the reader), to decide. Get some ceramic terminal blocks to connect the wires. The rest of the recipe is in this video. I am looking to design a "sword kiln" that can do swords up to a meter in length. Greetings, Jeff p.s. Dont forget to buy 3 s-type thermocouples, 3 40A solid state relays, 3 MAX31865 shields, and an arduino with cables, usb (printer cable) , and 230 to 9 volt 5,5/2,1mm converter on aliexpress. Once you know how to configure arduino you can make it really precise and if the heat on the top gets higher that the bottom, you can fine tune untill you get an even temperature. DO SHOP AROUND TO GET THE BEST PRICES!! One final note: be sure to get a solid state relay with good reviews, there are some cheap knockoffs there, but some good ones to, so read on your buy.. Or buy 1 s-type thermocouple and a thermocouple controller as used in the video, and than it should run.....
You shouldn't apply solder to the ends of wires going into screw terminals, as the solder will creep under the screw pressure causing the connections to loosen and fail. (To properly add a solid end, ferrules can be crimped onto the conductor; alternatively, there are some styles of terminal strips designed to prevent damage to the strands.) Also, good practice is to avoid touching the heating wires with your bare skin, as perspiration can shorten their life.
Use one layer of 74mm grade 23 bricks and one layer of 50mm ceramic fibre insulation and you are on a industrial level. Should be plenty good for what we are using it for
Amazing! It came out better than a bought one mate
both did a very good job so inspire me and make one for my bladesmith work shop thanks
Yo blackbeard, no offense, especially because ive never made something like this, but this gentlemans oven seems waaay safer than yours:)
Probably but like 10 times the price. Mine gonna look like really more like yours hehe
This is by far one of the most impressive videos I have ever seen on UA-cam. Great job.
I've not seen a better design and build. A true Tina Turner build (Simply the Best).
thats probably the nicest diy electricial furnace i have seen so far
This was one hell of a build. You went more than beyond on this oven.
Hi jess
Nice. I think this is the best Heat Treat oven build I've seen so far.
I got that enthralled in the video, I forgot what you were making at one point. such a pleasure to watch.
thank you.
Excellent build. One of the best I've seen. Your attention to detail shows in the quality of the build.
Nicely done. That saw is no joke! One has to have old school knowledge to go without all the safety features modern saws now include. Kudos to you!
Wow that an amazing, perfect, overkill oven. When perfectionist is your second name. Good Job !!
Great work indeed! I wonder what type of insulation brick/material you have used and what is their cost? This looks the same material that we see in commercial furnaces.
Velmi geniální.
Vynikající řemeslné zpracování
Very ingenious
Excellent craftmanship
You should sell those. Seriously. Absolutely amazing.
Great workmanship on both kiln and video!!
Wow this guy is a real craftsman!
Really amazing Job! Congrats!
Hello TRITT, the information you had impose, for me you're a God send!
I need one of these !.... Great inspiration as far as method and concept goes!
Lovely job man!
Paddy
What a sick build.
I would love to have one of those in my tiny workshop.
That's awesome! I appreciate your attention to detail! Looks 1000x better than the 'janky' stuff I cobble together!

Awesome work. How nice it could be if everyone would adhere to details like you do!
Úžasný! Jste FRAJER, pane!!!
Very professional. High tech.
Are the coils electrically isolated from mains voltage? Ie. will you get zapped if you touch the coils placing steel inside the forge
Very nice work Amazing craftsmanship
Excellent craftsmanship!
You are quite the craftsman.
Wow best construction I ever seen. Please may you tell the materials you used?
Zdravím, vedeli by ste poradiť kde zohnať tie ziaruvzdorne tehly? Na Slovensku iba samí Šamot. Ináč super práca.
Best electric furnace I ever seen on youtube. Nicely done :)
Boa tarde esse forno consegue atingir qual temperatura máxima
Great build, the best I have seen so far, if I could make one as good as that, I would be extremely happy.
Thanks.
Well done.... Its excellent craftsmanship!
Gratulálok,precíz és gondos munka!Profi.
As soon as I hear no narration and crappy music, I generally turn away from UA-cam but.. man this was a magnificent project.
Well done!
Amazing work and craftsmanship here
Excellent design and execution especially considering you weren't using high dollar tools! Thank you.
Super gebaut und an die Sicherheit gedacht. Wie lange benötigt der Öfen, bis er sich auf das Maximum aufgeheizt hat?
Wow very nice workmanship!!!
Dont you just hate people this clever!? 😜 What an absolutely fantastic job!
Wow, this is a seriously impressive build. Great work!
Beatiful build, can I ask what the inside dimension of the Owen is?
One of the best builds I have seen. But one request can you do another video going through the electronic side of it that would be great. You have inspired a lot of people with this one. Well done and good luck.
Still need help? Hit me up ill make a schematic for you
Wow brilliant build love it

Beautiful! Thank you very much for showing!
Impressive build and nice clean work. Subscribed!
Thank you, I hope soon to please :)
Very impressive came out beautiful brother
Amazing build.
Fantastic! Your design is superb and build quality A1. If you would like to make another I will buy it. Let me know the price, please.
Great work. Very nice construction and quality electrical work. What was the thin sheets you put between the fire brick and the steel plates/frame work?
Thanks for sharing.
Hi, friend, thanks. In my country it is called,, Sibral. "Search Special refractory insulation
Excellent build buddy, thanks a mil for posting this, could you please tell me where you got your bricks and controller from? I am in Europe and can only find the bricks in UK
Hello. you have to seek special refractory materials, I think, to find in every country in Europe

This is a very very very useful video.
Thank you for a video.
Very talented 👍
Potresti costruirmene uno e spedirlo in Italia? Quanto verrebbe a costare?
Hi,
nice work, I'm very interested to build something similar but bigger and for pottery.
is it lightweight concrete block?
It's a K23 lightweight insulating fire brick, which is resistant up to 2300°F (1260°C). There's also K26 firebricks, which take it up a notch to 2600°F (1427°C).
for a 150x150x600mm oven at 127v voltage so that it reaches a temperature of 1100 ° C which power and wire do you recommend?
Great work and amazing well done
Amazing work! Great video!
To je prostě super! Můžu se zeptat, podle čeho jste zvolil délku spirály z toho kanthalového drátu a jak jste zvolil průměr? Moc děkuji za každé info.
Very cool!!
Is it possible to read the temperature of the outside oven surface from more than one hand?
Congratulations on the oven! Can I know what materials you used?
Well done, multi skills.

what is the best way to hook up that element safely?... i see in your video you wrapped the ends three times and twisted it together.. do you just twist tie and solder a specific gage of wire to that end?
please forgive me if seems like a dumb question... just seems like there may be a common and best way to do it; that would be very good to know.

You shouldn't apply solder to the ends of wires going into screw terminals, as the solder will creep under the screw pressure causing the connections to loosen and fail.

Great video!! Very professional...which or the material of the wire inside the oven?..thanks a lot ;)
Kanthal a1
From where you bought these bricks ???? The type of brick is this ? Please share the data sheet of this brick. Or any other link
beautiful kiln man. well done.
Prosím tě co jsi použil za pid regulator.dik preji pekný den.JN
What is the board that you put around the bricks
What about your temperature surface ? And How to calculate thickness insulation ?
Use one layer of 74mm grade 23 bricks and one layer of 50mm ceramic fibre insulation and you are on a industrial level. Should be plenty good for what we are using it for
