DIY Heat Treat Oven

[@jbmaljbmal]

Best DIY video I have seen in a long time , Just GREAT.

[@tomsdreamshopworx]

One of the nicest seen on YT. Well done!

[@PaveW]

Thank You

[@homemadetools]

Nice heat treatment oven. We shared this video on our homemade tools forum this week 😎

[@PaveW]

Thank you :) Every like, subscribe or share motivate me to create new videos.

Sure why not :)

[@prometheus7504]

humanity will be long extinct and this oven will still be around =) great work man

[@mohsennajjari2367]

Good job 👏👏👏

[@lostbuffalo196]

You do GREAT work young man. Keep it up !!!!!!!

[@PaveW]

Thanks :)

[@gunfun7772]

One of the best diy videos.

[@LUCKYB.]

Well made Good Job.How far You Have came I remember Your First knife You Did on the tube . You Have to be proud of Your Self. Folks Also .Good Job 👍.

[@PaveW]

Thank You :) yeah knife from my first YT video leaves much to be desired. It's good to have this type of documentation, showing off gradual progress during every next project.

[@LUCKYB.]

@@PaveW More than progression .its a testimonial of Your existiants.

[@jimmynoname336]

Nice work bro . Interesting way to go about it . I like it and will use some of your touches on mine. Only thing I would do different is use a respirator when cutting any of this stuff.

[@1000186ful]

Very nice build and nice welding

[@Mithrilspoon522]

This is awnsome this profs u dont have to pay an insane among of Money for the oven thanks so much. Just 1 question. Is there any link or name listet of what the eletrical heater is called ? Regards.

[@PaveW]

Thank you, i used Kanthal A1 wire (1,2mm)

[@stevehaynes2857]

Hi, great build video. I am using it to guide my current build of an oven. Please could you let me know where I can buy those hinges - can’t find any like them in the UK? Thank you.

[@PaveW]

Thanks, search them under the name "gate hinges"

[@iamepimethus]

Dude, respirator it up when grinding that stuff

[@PaveW]

I was holding my breath while doing it. Besides, "respirators" have killed many in the past two years… Anyway fair point ;)

[@iamepimethus]

@@PaveW yeah I was less than conscious of safety equipment in my earlier days and the old timers don’t make shit up when they warn us. Now in my 40s I’m paying for mistakes. That thing looks awesome though!!!!

[@juandelafuente54]

I love it! This is the best video on how to build an oven. Could you tell me, if you remember, what is the diameter of the bar to wind the kanthal wire? Thanks!

[@PaveW]

Something about 10mm

[@MantisRay861]

The diameter of the coil doesn’t matter electrically. It’s only coiled to allow you to get enough Kanthal in your kiln. The length of Kanthal (or other high resistance wire) needed is dependent on your supplied voltage and desired current. Other than that, you want a coil diameter that will allow you to cut a groove in the bricks that isn’t so deep that the bricks crack. Since the bricks are brittle, you probably only want to cut into them less than 1/3 of their thickness

[@PaveW]

​@@MantisRay861 It's true, I used 10m Kanthal A1 wire (1,2mm)

[@MrSoloun]

Nice build, good vid.

[@gerardmartraix9483]

Very nice work, the advertised performance of your oven is impressive. Can you specify the internal dimensions of the oven as well as the length of resistance used. Thanks

[@PaveW]

Used 10m of ⌀1,2mm Kanthal A1 wire, diameters 10x15x40cm.

[@drhfhs]

Very nice saved for later

[@MantisRay861]

PLEASE WEAR A RESPIRATOR WHEN CUTTING THOSE BRICKS! Excellent video otherwise! I love the method you used to cut the coil groove in the bricks!

[@user-qy9rg3nt2l]

Some serious insulation. Should have no problem re-entering Earth's atmosphere.

[@Tim_E88]

Great job!! I watched your previous heat treat oven video afterwards and you made a big step up in manufacturing quality! Could you please describe the updates you've made to achieve the high efficiency/ fast heat up time? And could you please tell more about the power you are using? 10m 1,2mm Kanthal A1, 230V and 4kW will result in a too high surface load of 10,4 W/cm^2. Recommended is a rating of

[@PaveW]

I used better insulating materials, the total thickness of wall is twice as thick as before, I also used thicker wire to make the heater, which resulted in much better performance. The furnace reaches 800 degrees Celsius in about 15 minutes.

[@flynryan3053]

will probably not last long, where did you find those specs?

[@hinduspl]

where to find tool that you used at 11:23 please ?

[@PaveW]

it's "Car Sheet Metal Manual File"

[@cr10crers]

Nice video, What is the name of the cord to seal the door?

[@PaveW]

Thanks, thermal insulation rope but I'm not sure if that's the proper terminology.

[@DenneyKnives]

Great video. I'm going to start gathering materials for one. Also, what song is that?

[@PaveW]

Thank you, it's "Into The Unknown" by Whitesand

[@loganmott1817]

Glad to see you posting again

[@PaveW]

Thank You, I wish to have more time creating new videos, also unfortunately these days YT works a little bit against small channels which generally has a demotivating effect.

[@Scarantino76]

Hi my friend, excellent construction but the resistance is just not there, the sizing is not good because if you take 10ml of 1.2mm kanthal wire with a resistance of 1.28 ohm ml and measure it, it gives a resistance of 13.1 ohm and at 220v about 4.050 kWh of consumption. the resistance if you spiral it from 7.0 mm external and you stretch it to 1/2 of its length (10ml of wire become 1.3ml of spiral) and a factor of 3 watts per cm2 you would be at 1154kh well below the resistance tolerance table and you melt it in a very short time, to have a power of 4 kw you need a much less resistive but equally thicker wire and I'll give you an example: you should have a resistance wire of 1.9mm finished length of the spiral 2.2ml external diameter 15.2mm and a spiral pitch of 3.8mm and you will have a power of 4.282 kwh and a threshold of 3 watts anyway of 4.327kwh then you will be perfect for 1100°!!!!

[@OregonBladez]

I need to build one, is this 220v? What was the connector you used to connect the Kanthal to the electrical wire?

[@PaveW]

Yes, oven is powered by 230v, I used a standard electrical connector

[@patrickkelvin1823]

Parabéns ótimo trabalho

[@Ruoja71]

Hey, is the 16A fuse enough? From what I've read on the package 10m of 1.2 A1 kanthal is 12,3 Ohm. 230V/13,3Ohm = 18,7A I'm not an electrician though :D

[@PaveW]

I'm not an electrician as well, but everything is working fine for this time, one thing I had to upgrade was the cooling system of elentrition.

[@widneyburton5559]

I really, REALLY like this design. Probably the best DIY heat treating oven I've seen so far. I'm definitely going to build this. About how much did this cost you to make?

[@PaveW]

Thanks, about $250 in total

[@jimviau327]

​@PaveW - Wow! That is quite a fair price for such a beauty 👌 Impressive!

[@stephane3732]

Great ! how much does it cost? what can we do to heat to 1300°C ?

[@PaveW]

About 250$. Theoretically it should reach 1300 Celsius degree but I never tried to run that high, usually for hardening steels 800-1100 is enough.

[@johnli6736]

Hi what guage of the heating wire and lenght for 220 volt?

[@PaveW]

I used Kanthal A1 wire Ø1,2mm, 10m)

[@Sinaaa-y]

How many millimeters of nichrome wire should be suitable for temperature 1250 degrees

[@PaveW]

It depends, you should use Kanthal A1 wire or something similar, it heats up to 1400 Celsius, 10m ø 1mm or hier shoud be fine. There are some free calculators you can find online that schoud help you figure it out.

[@akosmarocsik9623]

Is it uses 3 phase electricity?

[@PaveW]

No, it's standard 230V

[@akosmarocsik9623]

@@PaveW thank you for the answer! I thought it's 3 phase because it heats up really quick. What are the specs of your electrical system?

[@matthewdavis454]

Is this running on 110v or 220v?

[@PaveW]

230v

[@alexandraodinlo2760]

Hi if possible and if you have time, I would like to ask you to build me a custom wheat treating oven

[@sarath6214]

What is the name this brick

[@PaveW]

IFB 23 Bricks

[@waqarshakoor9265]

what is power rating of this coil?

[@PaveW]

About 4 kW
