Holy moly man the way you cut in those heating element slots was genius
Thanks man! Glad you enjoyed that. Seems like a good solution for sure.
That is one of the best detailed and explained videos on oven building around. You did a GREAT job of designing the oven, AND documenting the build. Thanks for taking the time for all that video editing work.
Wow, thank you sir! Glad you enjoyed it for sure. Have a great weekend!
Ditto
Man I'm... amped! I don't think I'll be able to... resist... the temptation to build one of these ovens!
LOL! I'm charged up for you man... Good luck with your build; I'll be shocked... if you aren't successful. Thanks for... relaying... me your feedback on this video!
@@RedBeardOps Sorry to be cheesy... but I'm just over here... wired... on some coffee. I think I have the... capacity... to tackle this project, but we will see! :)
Thank you for sharing this! This walkthrough was super helpful and the equipment list is such a great resource. I created a parallel build and found that making the channels in the fire brick with tight tolerance for my coil diameter caused my bricks to crack when the Kanthal expanded. Maybe a lesson learned that could help other viewers.
Looking really good! I appreciate how much time you spent documenting and editing. Great reference.
Glad you enjoyed it! Man your blog was so damn helpful! Thanks man. Have a great weekend. 🙌
Great video! Coming from a pottery background, if you need to help keep the elements in their grooves, you can take old/extra element wire and bend it into a J shape. Then just push them into the soft brick where needed.
As always, I’m impressed with tour skills man. Super easy to follow along. And you go the extra mile with sourcing components for us.
Thank you
I appreciate that! I enjoy making videos like these builds.... They're something I wish I had.
Awesome tutorial brother! Exactly what I was hoping for. I will put my Red Beard oven right next to my Red Beard etcher. Thanks for all you do!
Heck yeah, thanks man! Have a great weekend!
Great video mate, you have clearly put a lot of effort into your project and into conveying useful information to viewers. Thanks very much for that!
Glad it was helpful! Cheers!
Awesome build mate! Very inspirational for an aspiring knife maker. Super informative and really well paced video. Thank you very much. Greatly appreciated.
Glad you liked it!
Another detailed and well thought out video James. You’re awesome. I appreciate you putting the cost list in there at the end. 👊🏻🇺🇸
Glad it was helpful!
Your build videos are second to none. Truly. Thank you. If you come to my shop you will find your press and your oven. To build these projects was inspiring. To document and freely share hit the high mark. Thanks again!
Awesome! Glad they were helpful! Cheers
Great job. I'm an electrician and very impressed with your explanation. You can add a cooling fan to box to keep components cooler. I have been wanting to make one and I love your design.
Thank you greatly sir! I'm glad I hit enough points to make an electrician like this one! I most certainly am not one.
Videos like this is the reason why I watch TH-cam. Excellent work
Thank you Dan!
Excellent tutorial! In the process of wrapping mine up. I have the first heat cycle going now. Just have to add a back panel and paint. You made it super easy to build. I appreciate it!
Heck yeah, cheers sir! Glad it helped.
Incredibly thorough and well-done. Thank you!
Glad you enjoyed it!
Finally a decent video, simple and proffesional, even an amateur like me can feel confident to give it a go,, thanks for tutorial,
Glad it was helpful! Cheers lu!
I completed most of the wiring today, just have to make and connect the elements, and detail the power supply. Fun build, man! Thanks for making it easy!
Nice work! Good luck!
Great video! Very detailed, straight forward and well explained! Thank you for taking the time to make the video and share with us! Cheers!
Heck yeah man! Glad you liked it! Cheers
This is a really awesome tutorial/video appreciate all of the hard work that went into this. THe knife making making community has some really great content and yor stuff is on the top of that. THANKS!
Glad you liked it Matt! Cheers
Man, what a awesome video. Easy to understand and your build is perfectly clean. Congrats and thanks a lot!
Glad you liked it! Thank you!
Nice build.
Thank you for going through the mistakes you made and how you corrected them as well. Thats a big help to all of us attempting tbe same project.
Glad it was helpful!
Absolutely superb video! I used it as a guide when I made my own control box and I just test ran it. Everything worked perfectly!
Thank you very much for having made this video.
Glad it helped!
Nice build - really excellent result, and very good and detailed description. Just a note for any one building one. There is no point in using two SSRs - one for each end of the coil, when you are on a single phase. The current you run through one is the same current you run through the other. You just get double the voltage drop over the SSRs (which is probably insignificant in this case), but main point is no benefit and twice the cost and hassle of wiring. And as noted by others, no reason to fuse the PID with a big fuse separately. The manufactorers pdf manual for the controller has a wiring suggestion for a heater build that should be followed - it uses the correct wiring with regards to fusing and using one SSR.
Yeah, a wonderful project:) And you are absolutely correct with your analysis: The wiring is SERIAL, one net-loop, so no need for two silicon state relays.
Just some engineering background (and advice, nobody asked for **g** ): Red Beard says something like "... a fuse to protect the PID [regulator] ...". That fuse should then be dimensioned to the max input current of the device, denoted by the datasheet. For the protection of normal devices 1.1 to 1.2 x nominal current / slow blowing fuse. Or to protect semiconductor devices (like SSRs) with 1.2 to 1.5 nominal current but with fast blowing or semiconductor rated fuse(Ballpark numbers, if present use the values specified by the manufacturer = RTFM:) ). But for such a small and relatively simple (in contrast to a complex) device? After all, also those fuses are ADDITIONAL to the ones he already wired in, which (the background part: ) are fuses to protect the WIRING! Like in your house-installation. They serve the purpose that in the event of a short circuit (heating element or regulator or the wiring itself or some dumb human juggling a screwdriver ...), the entire wiring does not turn into a fire hazard/heating element itself. The fuses must therefore be designed according to the conductor cross-section and thus the rated current. If the/a secondary fuse is dimensioned as a device protection fuse, then the correct value for the special device must also be selected. Anything in between, or "by feel" doesn't make any sense at all:) Just my (and by the basics of electrical design) 2 Amps ... I meant cents.
About Cable Glands: I found it wonderful, that he works with cable glands. That is professional. But ... cable glands are for ONE cable, each[1]. The great thing about them is the screwable and totally sealing strain relief. If you use two cables or even three .... then you can omit those things. And please don't say anyone DUCT TAPE. We have enough plonkers here, who shoot themselves in the foot, regularly on TH-cam:)
[1] That solves also the mystery, why they come in different sizes ... :P
About Thermoelements: Whats positive and what is negative? No needs to speculate. Red Beard has mentioned his "high quality super duper multimeter". USE IT! Use a heat gun and measure the output voltage of the element. Then you KNOW!:) (Also good advice for dogs and color blind people, hehe)
🙌
Dude! You crushed it man! Thank you so much! Parts, diagrams, everything! Thank you so much! Please do a follow up in a few months. Would love to hear how it holds up!
Thanks man! Glad you liked it. It's pretty much going to be used in every knife video I do on this channel (except for the next one since I had already made the knife without the oven). You should be able to get a good idea of how it's doing and I'll make sure to talk about it! Cheers sir!
Great video!! I’ve probably watched it 20 times. I’m a new knife maker and I built this oven with a few changes but it has been a game changer. Thanks
Heck yeah man! Awesome to hear it helped
What details did you change in your build, & why?
@@schechter01
I’m running off a 30 amp breaker so I increased the power.
Quickly becoming my favorite build channel, nice work !
Awesome, thank you!
Freaking sweet build... Can tell a ton of research went into it, thanks for documenting it all for us!
Glad you enjoyed it!
Excellent Job on both the build and the completeness of the DIY video!!!!
Thank you! Cheers!
this is awesome, my only problem. couldn't you have released this a month ago before I started building my propane oven lol. This will be my next oven build for sure, thanks for such a comprehensive tutorial.
Lol, sorry sir! Good luck on your build!
Thank you for compiling all the information into this video! I built a similar device a few years back, in seeing yours I now have solutions to the things I didn't like about my build. Thank you again! Now I have explore your other videos and subscribe...
Glad it was helpful! Cheers!
Really awesome vid mate 👍🏼👍🏼 the amount you learned along the way shows just how complex it can get!
I have talked to a local furnace company in my home town and they build hobby setups buy one thing the owner mentioned is that he likes to get his walls 120mm thick for safety and performance, he showed me his demo model getting up to 1100c in 20mins 🙀
Keep up the good work 🙌🏼
Very cool Chris! Cheers sir
Best overview of the DIY oven build I’ve seen yet ! And bonus, it’s a great design too !! 👍🏻👍🏻
Glad you like it!
Great video. I will definitely be watching it again when I build my oven. Also thanks for all the resource links.
Glad it was helpful! Cheers!
Brilliant! great job with this project. You really did your homework. thanks for all the detail, super complete. When i get ready to move past 1080/84 steel i am going to build one.
Glad you liked it John! It was a pleasure to build for sure... I think I like building knife making tools almost as much as making knives!
Awesome! The parts list with Amazon references is particularly helpful for all the little bushings connectors, etc. Thanks!
Glad it was helpful!
Really nice build on that oven. I just finished building mine about 2 weeks ago and although not as aesthetically finished as yours it does the job. I built mine with inside dimensions of width 6" x height 5.5" x depth 22.5". Wanted to be able to heat treat the camp choppers I make. Was able to do it for just under $500. Most expensive parts were the bricks and the angle iron since I didn't have any angle on hand. I used an Inkbird PID which seems to work quite well. I am having issues with the crappy hinge I used for the door so will have to go with something like you used. Looks a lot more sturdy. Again great build.
Awesome man! These things are fun to build for sure. Thanks for your comment!
Great project and really detailed voice over. Thanks for sharing. 👍👍
Glad you liked it!
you did 1 hell of ajob on that oven it came out fantastic glad you finally did this video i wish it was here a few months back but im happy with my oven i built
Thankyou sir! It was a fun project for sure. Congrats on your oven!
Best oven build around. Thanks for sharing.
Glad you like it!
Great job! Very detailed! I know I’ll never do something like this but it is a good idea LoL.
Again, great job!
Concise, well edited, and just well, awesome!
Glad you liked it!
That's a really slick build and nicely put together video explaining it.
Thank you!
Nice! You really had to throw the info at us quickly to cover everything, but it was perfect. Great detail and very clearly filmed, edited and narrated. Well done and thank you.
Glad it was helpful!
Great video and build, thank you so much for sharing it and all of the info with us, it is very much appreciated!

Brilliant... great build, Your presentation style and instructions makes the process easy to follow. Subbed here!
Thanks for the sub! I'm happy you enjoyed the video!
Nice video and well done. By far from the videos I have watched this seems to be the most details. Thank you for that, wish you the best in your future endeavors.
Glad it was helpful!
Thank you for making this video that lets hobby makers do very special thermal cycles.
Glad it was helpful!
Really great built video! Thank you for putting this up. I'm going to build an oven for aluminum casting and this will be a great help. Love the idea of using a benchtop drill press as an overhead router for the bricks - that's genius actually. If you used a regular router or router table all that silicon dioxide dust would probably completely destroy the router. But with the drill press, the motor and bearings are mostly out of the way. Such a good idea!
Came out of necessity! lol; Cheers Tom
Excelente video!! no te guardas nada, lo das todo, Gracias!
Great build and excellent commentary. I hope your rewards are many. Stay safe. Rex from DownUnder in Melbourne Australia

Vi ringrazio molto! Buona settimana!
The video was nicely done and easy to follow.
Thank you greatly!
Great build man! Really makes a HT oven accessible. We can buy parts a little at a time if need be to spread that cost over time.👏👏👏
Glad you liked it Wiley! Cheers sir!
Awesome tutorial, I´ve already made my own oven, but for me the main problem was the fire bricks. I can only find here in Brazil refratary bricks that were solids as a rock and to cut them were very difficult. I used only one SSR and after 10 min it melts, so I used a air cooler.
Your oven it´s great, on of the best diy on YT!!!
Heck yeah man! Thanks for your comment! Glad you enjoyed this one.
Great build video. Made an excellent working oven as good or better than one could buy.
Glad you liked it Glen!

Nice! Good luck and stay safe with your build!
@@RedBeardOps A few times through and, as much as I love the video I think I'm gonna tap out on this one and save up to buy one. Mechanical and structural stuff is one thing. But screwing with electricity at that level is a bit beyond my ken.

I'm a jewelry artist and it one point I was thinking of making my knives from scratch and than engraving them. After watching this video I think I will just buy blank knife blades from folks who have put in so much time and equipment into their work. There is only so much time and space we have to do the things we love. Your video has only made me more aware of the craftsmanship and skill that goes into knife making. Thank you.
Thanks Shaun! And good luck with your engraving!
