Are the coils electrically isolated from mains voltage? Ie. will you get zapped if you touch the coils placing steel inside the forge
how many ohms is the heater?
Thanks
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.
woah... not wearing a respirator when dry cutting those insulating fire bricks? bad bad bad for your lungs. Those things are made of Ceramic and Crystalline Silica. Ever hear of Silicosis? Lung Cancer? It does the same to your lungs that asbestos does. Aside from that, good video on making a heat treating oven. Sucks that electricity costs between $0.37 and $0.47 kWh here in Commiefornia.
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.
Prrfect
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!
Really amazing Job! Congrats!
هذا الفرن قوتة كم امبير . وكم هي سماكة السلك المعدني لو سمحت B.mallouk@gmail.com
Damn you could have listed the materials you used......
I've not seen a better design and build. A true Tina Turner build (Simply the Best).
nice build. What was the ohm resistance of your coils?
Zdravím, vedeli by ste poradiť kde zohnať tie ziaruvzdorne tehly? Na Slovensku iba samí Šamot. Ináč super práca.
15:26 what is it?
This is by far one of the most impressive videos I have ever seen on TH-cam. Great job.
Nice. I think this is the best Heat Treat oven build I've seen so far.
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).
Please, attach the plans and diagrams.
Hope your lungs are alright man. Anyone working with soft firebricks, please wear a respirator. The bricks contain crystalline silica which is a known carcinogen when inhaled.
Potresti costruirmene uno e spedirlo in Italia? Quanto verrebbe a costare?
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 would hang the sword in.
Wow that an amazing, perfect, overkill oven. When perfectionist is your second name. Good Job !!
Beatiful build, can I ask what the inside dimension of the Owen is?
bravo brate dobar posao
muito muitoooooooo legal,um espetáculo seu trabalho,parabens merece muitos likes.
Table saw looks like a death trap but an amazing looking heat treat oven, well done. Lol
for a 150x150x600mm oven at 127v voltage so that it reaches a temperature of 1100 ° C which power and wire do you recommend?
Boa tarde esse forno consegue atingir qual temperatura máxima
Super !
Cutting them silica bricks on a saw not to mention no respirator is a horrible idea.
Great workmanship on both kiln and video!!
Great build, the best I have seen so far, if I could make one as good as that, I would be extremely happy. Thanks.
what is he max temperature of this unit?
Would not be surprised if this guy is dead, what a dodgy dumb fuck. He has zero idea about safety. Not even wearing a respirator cutting ISO bricks bahahaha
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!
You should sell those. Seriously. Absolutely amazing.
Parts list?... :)
It is not possible to get the electronics, sensor and wire.
Lost me at the controller
Very talented 👍
Beautiful job! One question....what was the white liquid at 19:00?
Velmi geniální. Vynikající řemeslné zpracování Very ingenious Excellent craftmanship
Can you please help by telling materials used?
Excellent design and execution especially considering you weren't using high dollar tools! Thank you.
That's an amazing build , thanks for sharing.
Wow best construction I ever seen. Please may you tell the materials you used?
Dobrý den. Chci se zeptat, jaké maximální teploty v peci dosahujete? Děkuji.
You are quite the craftsman.
