DIY Heat treating oven (build video)

[@AM-dn4lk]

Beautiful work. You brought together several disciplines, welding, sheet metal work, electrical, control systems, kiln knowledge; and executed them all masterfully. Great job.

[@todds1709]

Have you noticed all the epic builds on YT comes from normal folks like this and not the ones with thousands of dollars of equipment in a seperate shop with bubinga wood cabinets. This dude is in his slippers at night with hand tools. Awesome work

[@raphaelschaaf5606]

Finally someone that uses a limit switch and grounds the enclosure. There are way to many build videos where people have no idea how to handle electricity. The connection between the wire and kanthal on the back should also be in an enclosure, since that is a live wire.

[@Legacy_876]

Hey I am having problems setting up my electric kiln, can someone help me out please, I am using REXC100 PID, 2500W heating element, SSR 40 0-32DCV and a LED transformer 20-40DCV....it gets going for a few minutes but then the heating elements stop heating can someone help me please

[@AlessioSangalli]

Why the limit switch? You mean the one that turns off the system when the door is open? Why is that desirable?

[@leonbarnes1402]

@@AlessioSangalli so you dont electricute yourself if you touch a knife against the heater wire

[@AlessioSangalli]

@@leonbarnes1402 because of the high surface resistance the risk is very low, however a switch of that kind is sure to tank the oven performance when it most needs it

[@leonbarnes1402]

@@AlessioSangalli id have thought the only time you would open the door is when your adding knives or removing them. you wouldnt need to keep opening it mid heat treat as you bake them for a set time.

[@tvjknives9247]

What steel are you using to Secure the heat element inside?

[@leeharveygriswold6160]

That's what I was going to say

[@AllesHandarbeit]

Best hardening furnace I've seen on YT ... greetings from Germany ...

[@33europe52]

A couple TIPS; 1. Try to use a thermometer that is made out of steel. Ceramic thermometers tend to break faster. And when they are exposed to high heat, they don’t measure as well. 2. Use more insulation. Preferably high heat ceramic wool. Now your oven needs to work longer to get to a certain temp. Best combination is using those white high heat bricks and ceramic wool. Plenty of it. But for the rest, very nice build!

[@Miomi-dh4hx]

S type thermocouple is excellent

You are a terrific fabricator, the world could use more like you. It's an acquired skill not being picked up by as many younger folk with bright minds like yourself. Keep making the most of your available resources, and I hope you enjoy a long, productive life's journey - Great work!

Man are you serious? That's like some world class piece of equipment you just built! I could probably duplicate it, but I get lost in the electrics and electronics department. Incredible job, incredible video!

[@brandysigmon9066]

You can build one, just take your time

[@jamal69jackson77]

@@brandysigmon9066 indeed I believe I could if I knew how to wire the electronics, but but without having specific guidance it wouldn't matter how much I took my time, I would not be able to do it properly. I would require a step by step visual video or live guide because I do not understand electronic and wiring schematics that are in printed diagram form, unless they are very specific and explanatory and they rarely are easy to understand unless you are well versed in these things to begin with. But thanks you for the vote of confidence 🙂

[@randomguyfromtexas1185]

Jamal69 Jackson I’m the same way, I can build just about anything in the world, but when it comes to wiring and electronics I am screwed. I don’t understand electrical schematics at all unless they’re written in crayon and explained to me like I’m a 3 year and then I’m still at a loss!!!

[@jamal69jackson77]

Thanks AV that was at a totally different level, From the design to the build, execution to the detailing, right down to the vid itself brilliant, thanks so much. Loved it all.

[@AlphaBobFloridaOverlord]

Very nice workmanship! I’ve got one that looks very similar, but is about 50 years old (I upgraded it with a PID controller / solid state relay about 10 years ago). Mine is ready for new fire brick, and a new steel shell. I’m going to put a slab of steel in the bottom of mine so that the steel’s thermal mass maintains even temperature. These ovens tend to fluctuate a bit, especially when opening and closing the door. Again, outstanding workmanship and thank you for sharing this video.

[@felipenascimento1986]

Thank you very much, with the video and list of materials I will be able to build mine, it will be 1/3 the value of a similar industrialized equipment, greetings and thanks from this young Brazilian blacksmith.

It's been what well over a year now. What would you have done differently? larger box? Thicker insulation? different electrical controls? How has the ink bird PID worked out for you? Does it let you Ramp over time up and down? I did like the scratch stock trick you used to make the slots. How long does it take to come up to the critical temp for the steels you use?

[@amschind]

I have never seen a 240v PID before.....I don't know why, but I always run mine on 12V. If I had to give a reason, I'd say it's that I want to limit high voltage AC to as few places as possible, where I know that 12VDC won't kill me if I touch the wrong thing. I do really appreciate seeing which wire you used as a heating element.

[@sebastienc8797]

The contactor on the door is the "limit switch" ? It's meant to shut down current in heating elements when the door is open to prevent electrocution ? Very amazing result, very professional.

[@joshyingling]

You won't get electrified from heating elements to begin with.

[@sunriseshell]

It stops the heating if the door is open. Prevents the element from burning out should the door be left open. Also reduces the visible and thermal radiation making it easier to access.

[@hesperhurt]

@@joshyingling you will if you allow it to become heavily oxidized and it snaps whilst you're loading the thing. Running any electrical kiln with full flow oxygen will burn the elements out in no time. The high heat creates continuous positive pressure which prevents high levels of oxygen rich air accessing the chamber. With the door open, with no interlock, it'll simply cycle the air from below to above and oxidize. The spring wires become brittle, snap whilst heating up and dislodge during loading. Ceramic kilns have the interlocking system for just the same reason after quite a few ceramicists were found slumped, dead, in the workshops. No BS... I've worked with, built and maintained ceramic, glass and enamelling kilns for 20 years 👍

[@sebastienc8797]

@@hesperhurt very complete answer. Thank you ! There is no solution to prevent the resistance to be oxydised ? Coat it with a cement ?

[@hesperhurt]

@@sebastienc8797 thanks buddy 👍 You can cut kiln brick inserts that sit over the wires. Without pictures (I wish YT allowed picture comments!!!) it's difficult to explain. Imagine the channels being drilled through a brick... then you cut the brick so that you cut the hole in half. These are then held in place using, usually, high temp ceramic rods. This means that the elements are contained within their own atmosphere and the chamber can be left open. Great for small kilns for enamel work where you're constantly moving a piece to get the right look. Mostly these are very small chambers (150mm3) and you load them from the underside. The top is very heavily insulated (minimum of 200mm brick topped with fleece) and the kiln sits on legs. You could totally apply this to a forging kiln... just upscale it an be sure to seal around the kiln brick sandwich with high density kiln board. 👍 Asbestos used to solve a lot of these issues... but killed loads of people (painfully) so we use a generic refractory fibre and cement now; compressed in a mould to get the correct forms and thickness. 👌
