Hey man, great fan of these foundry/oven videos you have done and am considering creating one myself. Am I right in saying the heating element works via induction? Also could a similar setup reach a temperature that could melt copper or even steel as well as heat steel to a temperature that would be soft enough for forging? I would very much appreciate a response if you could spare the time and I hope you go on to do great things.
I saw someone else using some metal shower hose to make the wires look a bit more 'professional' and I figured you might want to know about it for future projects. The metal is really flexible, but obviously still metal so it would help the wires not get damaged. And the plus side it is cheap!
Could I recommend that you use a rubber or insulating grommet around the cable exit hole on the back of the electronics enclosure.... to reduce the risk of cable chafing / shorting against the metal plate. I llke the design, and the explanations are very helpful. I'm going to guild one!. I know this is 3 years old, but worth mentioning. Thanks for the videos.
I just love this type of videos. Wish I could build this furnace... I´ve build actually made similar one to the previous you made and it worked flawlessly :) till the coil melted... to be honest i haven´t spent nearly as much time as you did but im glad i could make it and thank you very much for showing all the details in your video. It was really helpful ;) so keep up the good work mate and good luck with future projects.
so I found this channel from the melting HDPE into sheets that was from like 2014 I think, wow your voice has changed lol - anyways you are really smart and do great work keep it up
Well done. I have some questions regarding the pid controller. Is that inkbird itc 106vh? What are your opinions on this equipment and where can you buy it? thanks.
Well blow me. I watched a random suggested video of kid making catapults from melted bottle caps, clicked on the channel and now I'm watching a grown man building his own heat treatment oven!! Wow a true child of RU-vid. Hat off to you young sir an inspiration to all young people. Im hooked and subbed. Ya got me...
What temperature does the outside of the oven get to? Im making a oven my self atm. And i use 25mm of ceramic wool to insulate the outside of the bricks
That Knife Turned out Epic, you Should Post Some Knife Making Videos, also you might want to make shorter videos, around 10 minutes long, that way you can get more views and people will stay interested.
TAOW, You don't need to squeeze everything down into a single video. You could have easily made this into 3 or 4 good videos, or at least 2 -- one building the oven and one making the knife to test it out, hardening and tempering the blade. Now we want one of you finishing the knife, attaching scales, and polishing, etc. Good job. Did you say you don't have a good belt grinder? New project?
Yeah true I could have split this one up into a few parts, but I wanted to demonstrate the oven working on something useful, and a simple file knife video has been done thousands of times and is nothing new. I do have a cool video planned on the handle scales tho :)
Congratulations the quality of your content and production impresses me more with every video. Glad to see you are back at it after your break! Keep up the great work.
Really nice kiln, i bought mine because of the electronics, but i built my ribbon burner forge and belt grinder...anyway you are by fare my favorite RU-vid channel since few years, i'm 16 so i'm really interested by the works of young peoples like you.
Project idea = Make you a bad ass grinder that would suit any need you have? Since you said it in this and other videos that you dont have a suitable grinder.
Well done mate. Quality video. We all appreciate the enormous amount of work and effort you put into these projects. Not to mention the editing and everything else which goes into making such excellent videos.
Insanely awesome build! How hot does this contraption get on the outside surface when in use? I thought maybe building an aluminium extrusion frame would be an option for those of us who suck at welding?
Wow, this is simply amazing! I love this project and will try to copy it. What would you estimate the all-over costs for the material? The workload is of course impoosible to calculate and you can't put a price on that. Thank you so much for putting this together and sharing it! And one more question just popped up in my mind: as far as I can see you only used elektrodes for welding, no other machines. Would you do it again that way or would you recommend trying some MAG/MIG welding instead in the future?
i love your content! i am a fellow knife maker and i also build a similar oven, using your older videos as part of my guidance. Although i build my own arduino based temperature controller. I dont trust the thermocouple you used by the way, i used the same ebay one and it went bad after a few high temperature runs. edit: the thermocouple still produced a temperature signal, but was off by almost 100°C
What I would have changed is built a rack to set item on inside the oven then mounted the thermocouple around the same height as the rack to try and get a more accurate reading. But im not sure how much this matters.
for those looking for the door interlock like i was, the part reads 'Limit Switch TZ-8112'. it's a 5A/250V NO/NC switch. thanks for the video, big help in planning my own build.
When you were designing the handle I was like "Tbh i would probably weld it to the wrong side". I guess i'm not alone in the world XD Great video, i love all of the stuff you do. I've always been scared of projects involving super high heats so watching you design and build a heat treatment oven basically from scratch is super cool!
Very professional looking heat treat oven, well done. There is just one thing that worries me about this oven and it worried me about your previous furnace build too - you don't appear to have earthed the chassis. You must earth the metal chassis and run the oven off an RCD - you have live heating coils and other cables in very close proximity to metal you don't want to be live.
Don't worry, I grounded both the frame on this oven and for my foundry. I didn't explicitly mention it in this video but it's mentioned in the wiring diagram towards the end.
thermocouple placement is a mistake. The front of the oven is going to be cool while the back-top will be accurate. bottom of the back of the oven might not be the right temp either.
I used to quench in motor oil too but han I found that any cooking oil like sunflower, peanut makes a so much better smell when it's quenched. Try it! I'll have to say my parts are smaller though.
Hi just spent 1hr looking for the handle cant find it any help please I will be using it for about 4 protects I have thank you Ah ha found it (Spring Stove Handle)
I know you since the slingshot videos, and I am impressed on how you've improved, you are very talented! Looking forward to seeing more videos like this. Keep up the great work!
I am planning to built a hardning oven. In your electric plan i see from contact 9 and 10 on the PID controller a brown and blue cable and contact to power lines. Can you explain?
Congrats on the build man! I intend to build this very same design for annealing glasswork. One helpful tip though, although your intentions were good with the cable strain relief inside the box with the bolts. You should really install a legit strain relief in the back of the box where the wires enter the box. The purpose of a strain relief is not only to prevent the wires from being pulled out, but also from chaffing on the enclosure where they enter. It wouldn’t take long for that metal to wear through the wire insulation. With that much current going through those wires it’s a definite must have! Great job on the build man! You’ve earned a sub.
the limit switch is unnecessary for electrocution safety. not only are your coils in a pocket in the walls but you would get burned badly before your hand touches a live coil. there is no way an ungloved hand would go near 900c heat without burns from heat first. Unless you got some ninja skills and the pain tolerance of a granite rock. The hair on your arm would burn off too. I can barely stand a 900c kiln with welding gloves on for more than a few seconds.
What you really need is a belt sander! I got a cheapy 1" and can't think how I lived without one before. I also got $100 portable bandsaw that has been enormously helpful, I've been meaning to make a "chop saw" stand for it but right now it sits in the vice and works ok for my needs.
Good vid thanks for sharing. Did you have any problems running the load through the cheap 20a switch? I used a cheap switch also but I was worried about running high loads through it so I ran the hot all the way to the SSR and then jumpered back to the 20a switch to power my PID, fans and amp meter. I was just wondering if you have fried a switch or not. I am not saying you are going to cook It. I just didn't trust such a light weight super cheap switch on my set up. I mean I did but I didn't want all that current running through it. Anyway well done looks really nice.
TAOW is that you? I barely saw my first video of you today, you were quite young making sling shot handles from recycled bottle caps of plastic. Now here you are a young adult? I'm so confused.
Excellent build! Regarding all the welding, I'd absolutely recommend getting a tig-welder!:) No slag (so no clean up), easy to get beautiful welds, and an incredible dexterity when it comes to the amperage settings. And you can do tiny welds or heavy duty stuff with the same equipment. I'd be surprised if you don't follow This Old Tony yet, but there you can get a lot of tips an inspiration regarding tig.
Great work! I'm trying to make a muffle furnace (a little bit like this), and I need help as per how to make the furnace door, add an actuator switch to furnace door as you've done in this video and do the wiring of the furnace. I look forward to hearing from you. Best Regards...
This whole project is so well thought out and briljantly exercised. Also, maybe it's me but I think you have a realy good voice. Where I'm concerned, make long videos, it's interesting.
