DIY Electric Oven With PID Controller. Part 1 of 2
ฝัง
- เผยแพร่เมื่อ 22 ธ.ค. 2016
- I made this electric oven salvaging parts from a toaster and adding a PID controller to keep consistent temperature. I will use this primarily for tempering knives and to melt down material with low melting point since this oven can reach temperatures around 300°C. This was an opportunity for me to experiment building with concrete and plaster! I'm also new to temperature controller, but that part of the project went pretty easy. :)

Thank you for not editing out your failed attempt, this can help others.
Could not agree more!
Part of the learning curve :) Thank you guys!
He's probably lucky he was able extract the form on the second attempt. A core with deep square sides stands a chance getting stuck no matter what you do. A better idea is to make the core so it can be taken apart and removed in pieces after the pore. Or tapering the sides slightly . In any case he could have saved the first pore by burning out the stuck core. Of course you'd lose your core mold, but if you were only make one part that's no big deal.
Sorry my mistake! He did make the core to disassemble on the second pore. My video stopped playing and I thought that was the end.
failure can be a great teacher in itself.
The music syncs so SICK!
You got me hooked in the first 5 seconds
Awesome cliffhanger haha can't wait to see the next part 👍🏼👍🏼👍🏼
Haha! :) Thank you my friend!
Black Beard Projects on your first attempt.....why didn't you just put it outside and burn the wooden former out?
I love the concept of a oven with a lot of mass. I would ad an insulating layer around it just to keep warmth in the oven, can't wait for part 2
Thank you sir :)
I look forward to part 2 :D
Thank you my friend :)
cool man. Im looking forward to the final piece!
Thanks! :)
Awesome idea!
Thank you my friend! :)
That's pretty cool I like the general idea I might eventually do that
Thank you buddy :)
Nice video man, I like how you leave in the mistake so people know what to look out for!
Thank you my friend! :)
You leaving that fail part in was a really humble thing to do! Much respect to you! This truly says that youre not just showing off but also giving us valuable material to learn from! Can i ask, why you didnt add 4mm rebar in it?
Pretty sweet.
Thank you mate :)
loved that you showed the fail,this will help in the future pretty good
Thank you Atli!! :)
Imparare dai propri sbagli è sempre motivo di crescita. Aspetto la seconda parte ;-)
Verissimo :) Grazie!
That is brilliant!
Thanks buddy!! :D
Fantastic !
Thank you!! :)
Excellent video, and thanks for keeping the failed attempt in; it's a massive confidence boost to see others trying more than once before success too! The second mould you made was excellent.
I see you watched many of my videos man! Thank you a lot :)
No, thank you! I have always maintained that the mark of a true craftsman is being able to make their craft look easy, and therefore attainable and inspiring to others - Your videos do this, and they are also very professionally produced and edited. I find them easy and enjoyable to watch, so hope to get through all of them eventually. Please keep them coming Mate! All the best.
Much appreciated :) :) All the best for you too sir, have a nice day!
Good idea
muito bom parte 1.
Man I cringed when you had to smash the first one, looking forward to part 2! Didn't realise your Italian, great to see more makers appearing form this side of the pond these days.
Haha :) Yeah that wasn't funny! Thank you mate :)
I recommend turn it on on 24 hours at 180 degrees centigrade so moisture evoperates and it doesn't crack then heat it up to proper temps
Yeah I'm doing a slow heating process, looks like plaster keep a ton of water, it's taking ages to get really dry without the risk of cracks xD
yes i saw a video there guy left plaster drying over night but still smoke there coming out and it cracked so 24 hours or more is probably needed for safe use
Yeah, by the way I'm leaving it at 70°C for now, I'm afraid to get near 100°C because the plaster is still really humid :)
i think this should be suitable temperature for know
You have my respects in keeping the failure. However Im sorry for you floor man 😅. I'm sure it was a quick video and thanks for sharing
Why didn't you wait for the cement to dry and burn the wood in the first oven?
Thrown stuff away unnecessarily.
can you list the materials you used. and what were your results after use!
So it's a 'DIY' oven ... made from an oven. Got it.
Superb video. How would you change things if you wanted to achieve 1400°C for pottery?
First off. I LOVE it. Definitely interested. Second. I wonder if you can put steel wool or something in the plaster to strengthen it. Awesome video!
Thank you man!! :) Yeah that would have been better, even some steel mesh inside. Dunno why I thought about that just later xD
Black Beard Projects either way. This got me inspired. 🖒
where did you get your PID controller from and do you think its possible to make your own? Did that one have a 'gain' adjustment?
Whats the difference between this oven and the other heat treatment one? How the other one reaches 800 degrees while this only 300? Is the difference in temperature because the insulation bricks aren't used here?
this is weird and awesome.
Haha thanks brother.
for the first fail you could've used fire to take out the wood mold
Yeah that was the only way probably... and a mess too! :) I was feeling better breaking the concrete :')
How much cost of temprature controller meter
Did I miss the PID controller details, such as product description and where you got it? If this is listed already, please direct me.
How much did you spend on the materials for the plaster? Do you think it could hold up to a propane burner? What did you mix with the plaster and in what ratio?
The plaster was way cheaper than the concrete: 8 Euro for a bag of 25kg and I didn't even used it all. I never tried a propane burned but I would guess that is too hot for common plaster, I think it would degrade pretty fast... I didn't added anything to the plaster, just water! :)
Thanks!
Which type of rods u use in this process
*HOT* Rods!!!
:
Dear Sir I know good English but when watch⌚ your video I confused. Making readymade parts important plaster name, heating road, Temptreure meter etc. & wiring diagram . One more question when🕒❓oven out side touch, shock current please explain. I am very excited making oven. Namaskar.🇮🇳
nice video
but why do you need it to temper steel. why not just use a regular convection Oven that works out great for me
Yeah for tempering steel the kitchen oven is fine, but when I have to melt something down like hdpe or to cure materials I don't like to do it where I later on cook my food :'D Thank you sir
+@@BlackBeardProjects
I guess you don't drink milk or bottled water?!
:
looks like making that box for the oven made one unholy mess.
What type of plaster did you use??
The cheapest one. Hem I mean, regular one xD Refractory cement would have been better but I was going to spend too much to buy it again, and I hope plaster will be enough for this temperatures :)
you are somewhere from Europe right ?
Why did you choose plaster over refractory cement for the second go?
Because cement was going to be too expensive for this experiment xD It cost way more :(
@@BlackBeardProjects >>> Was there any need to add any kind of wire[?] to the plaster for internal reinforcement, the way rebar is used with concrete?
Do you have a wiring diagram?
I connected the heating elements as they were in the oven :) For the pid I followed the diagram that came with it, nothing strange :) If you want I can send you that diagram!
why not simply burn the inner form of the first oven instead of breaking it?
That would have broken everything for sure, you need to slowly cure the plaster or it cracks badly xD This can be an option for a larger oven with different material. I did that for my aluminum melting furnace back when I built it but the inner mold was made of carboard :)
where did you place the rtd? i didnt see in bouth videos
I drilled a small hole in the top of the oven and inserted it there with a bit of high temp silicone :)
Black Beard Projects thanks man, great job
the plaster isn´t that insulating is it? and what are you going to use it for?
Yeah not the best insulating material, but for these temperature should do just fine :) I went with that because I was going to spend too much for another batch of refractory cement! xD I'll use this to temper blades, melt stuff like hdpe and possibly cure and dry out other material like plaster molds if I'll have any chance :)
Black Beard Projects Do you mean just tempering or hardening? Its a diffrent thing.
Tempering! I point that out at the beginning of both this two videos :)
Black Beard Projects ok :), i thought you have mixed them up somehow since you could use a regular oven for temering.
Yeah sure :) for blades the oven works fine, is for other nasty stuff that this will come handy! So that I don't release fumes or chemicals where I cook xD
scusa ma ti devo chiedere qualche consiglio sul termo regolatore che hai usato. vorrei sapere se me ne puoi consigliare uno che vorrei fare lo stesso lavoro. o magari quello che hai usato tu si imposta con temperatura in salita 1 grado ogni minuto, e' per la cottura del carbonio.
a presto luca
Ciao! Quello che ho io non ha le salite, quando l'ho preso era il meno costoso su ebay . com. Non saprei davvero consigliartene uno buono perchè questo è l'unico progetto del genere che ho fatto e non ho altra esperienza... Qualche tempo fa però ho visto sul canale "Makercise" la costruzione di una forgia a propano con regolatore di temperatura tramite raspberry pi, molto ben fatto, magari trovi qualche spunto li! :) Ciao
Black Beard Projects ok grazie mille
On that 1st fail, couldn't you have just burned it out??
I did it with the help of Avasva solutions.
you could have burnt out the wood
Maybe burn it out?
Yeah might have been the only solution :)
You mean DIY oven housing
If you didn't notice it's a 2 part video :)
Curiosità! Hai imparato da solo su tua esperienza personale? :D
Si! :) Tutto quello che faccio l'ho imparato guardando altri, sopratutto qui su TH-cam, e provando di persona :)
Complimenti allora! :D
Grazie! :)
Wait, did you seriously use plaster for this? That wasn't just a test?
I hate to tell you, but Plaster breaks down at 400 F. :/
Yep only plaster :) As far as I know it last well over 400°f we'll see anyway, I already tempered a blade at 392°f for 2hr and I'm going to temper a lot more in there! :D
I HATE TO TELL YOU THAT WONT GET 400 F MY FRIEND
Destroys an oven to make an oven : l
burn it out!
Couldn’t you just burn the wood off? Throw it in a fire. I mean, it is an oven
Why are you wasting a good oven in making your own one.
Because I like to experiment! Also I've used this oven a lot in many of my videos, so it's not wasted at all for me :)
