Turn an old Oven into a Kiln

Join the science discord! / discord Hey everybody, ive been busy the past two weeks! I had a great time at Playlist Live, and finished some much needed organization in my garage. I finally got around to building a large kiln to help me make investment molds for aluminum casting. Now I can finally get this laser gun built! Keep reading, more below!
Shoutout to Keystone Science! / hobcoman
I couldn't find any info on any projects like this, so I thought I would have a try myself. I thought an oven would be the perfect platform, it already has a door, space for insulation, and comes with heating elements!
Im not giving the oven any more power that it would normally use in Self Cleaning Mode. Im just increasing the efficiency by adding high quality insulating materials and eliminating ways for heat to escape.
The oven was almost exactly $270 to build, which is about $200 cheaper than a used kiln on craigslist. and 1/10 the cost of a new kiln. I could only get it to 820c - 1500f, Real kilns can get to 2300f. I think my kiln could get that hot if I wound my own heating elements with nichrome wire and added another layer of insulation.
Oven - 40
Morter - 25
Ceramic Blanket - 120
Firebrick - 40
Temp control - 30
Everything else - 20
5.6 kw = about 30-50c an hour to run. I pay 5-9c per kWh.

Vermont potter/maker here and I LOVE this project! Lots of possibilities...! Thanks also for workshop tour. So much open space in the middle!

[@electronicsNmore]

Looked like a fun project. :-) You put a lot of time into it, and did a great job. I wonder how long the heating elements will last at 1400 deg F. Thanks for the links!

[@TheBackyardScientist]

+electronicsNmore thanks it sure did take a long time. Don't even get me started on making the plaster molds and the Burn out schedule. The heating elements? I think they will last. I guess they are steel tubes with Nichrome wire through the middle insulated with magnesium oxide. It won't get as hot as nichrome elements I could wind myself. They are 18 and 22 ohms. If are used lower ohm heating elements I bet I could get the temperature a lot higher.

Hi

[@homnef4789]

Why would anybody dislike this! He's always so jolly and excited he spends lots of money on this. Just so hater can come and be jerks. He puts effort into this , like c'mon guys

[@aminelaareg2472]

Kiyguo the Artist all those dislikes are are grant Thompson "fans" that think he should be the one and only

[@joes9987]

i like both grant and kevin :c Can't all fans get along? Spread positivityyyy

joes9987 true, they are both good channels with similar content

[@zakirhussain6683]

Kiyguo the Artist so true he don't have to do this but he does so cut him some slack he does it in his own time and spend loads of his money he earns and you disliking it

[@jackofsometradesjack]

maybe cause dislike =/= hater. a dislike is a critique and tells the channel it can do better.

[@johnsanchez8029]

Dude I appreciate the video. A while back I disassembled an oven to scrap the metal and kept the heating element. Was very hesitant because I wasn’t sure if they were tough enough to hold up. But now I know. Thanks again man

I'm happy for you and the new house! it's always a good feeling when I see someone's hard work payoff. hope to see some improvements to the yard and house itself so record those for us too!

[@marc-andreservant201]

Depending on how old the oven is it might have been asbestos.

[@shpongl]

Really awesome project. I'd suggest pre-heating moulds before casting and use cone shaped risers for increased pressure. When i worked in a foundry we never poured into anything without risers.

[@jameslehman4331]

[@gamerbrian1433]

Isn't this exactly what Linus tried to do and miserably failed?(Not the oven part, the 3D printing and casting part)

[@JohnD201]

Sort of. Linus tried to do aluminium casting, like what happens in this video. However, the difference arises in what they were making. It looks like here he made a lower receiver for a gun, while linus made the heat sink. It is an important difference as the space between the heatsink fins make it extremely hard to cast, while the larger overall size of the receiver allow for easier casting.

[@TheBackyardScientist]

I haven't seen that video but yeah a heat sink would be extremely difficult to cast without some kind of vacuum process. Pretty sure they are just machine from a solid chunk. That is a lower receiver I made but.. it's just going to be a prop Halo gun :P which may or may not end up shooting a 40 W laser beam.

[@Kevin-yg8fe]

Could I potentially used this solely as a foundry? I really don't want to spend 500+ dollars on a foundry if I don't have to. It seems as if the oven would be extremely hot just to be around when it opens.

[@TheBackyardScientist]

+Shadow Runner it could. It melts aluminum easily. It's easier, cheaper, and quieter to use than a gas foundry

[@Chris-jo1zr]

but I bet it destroys your electricity bill.

[@Kevin-yg8fe]

Instead of using a clay graphite crucible, I have seen people use fire extinguishers. Do you think using a steel bucket would work also? Or is it just too thin?

[@alcapone5791]

definitely just keep building your main channel. This was good content and opens the door to more videos and possibilities

[@RamiShreds]

TheBackyardScientist I personally perfer more experiments. But you have a huge following so I'm sure a sizeable amount of people want videos like this so they can try out their own experiments! Another channel would help keep both camps happy. Keep up the great work!

[@alcapone5791]

No, 99% of viewers will not try this at home. Anyone who tries this at home already had the intentions of doing so before watching this video. I like watching things like this because i will never go out of my way to transform an old oven into a kiln. Its kinda like watching "how its made"
