I used my router with a carbide 1/2" bit on the router table. I attached a vacuum hose to the base of the router to take care of about 90% of the dust. Quick and easy.
John, again your tenacity is admirable and inspiring. You Sir are among a few left that actually do things, and are not afraid to have some fun along the way. Thank you.
I hit like as soon as I saw the wooden vise.
Luckily, you were able to use the tactical muffin top as a third hand. I find mine to be pretty handy too. :-)
As a Vaper, I use this site to figure out ohms, wattage, wire size/length, etc.

John, I love your videos man. Your dry sense of humor reminds me of my Dad's, and my own. I genuinely enjoy watching.
Really cool! I am enjoying this build very much.
Great video. This is the kind of project that got me watching you in the first place. Thanks John
Nice job! Thanks for the video.
John Heisz, Professional Contortionist Extraordinaire!
another victory - thanks john
Thank you for video.
If we were anywhere near each other, you would be my best friend. You wouldn't feel the same about me, but this isn't about you anyway.
Great build John, looking forward to seeing you use it . great use of the roof over the tool shed to support those bricks whilst you were assembling , like most real men i also have a body simular to yours and the extra frontage comes in handy for that extra bit of support.
Looking good, can't wait for the first test of this thing :)
Congratulations John. Mr. Wizard would be proud. I would have dropped those bricks and element putting them in. You've got better skills than I do. Nice nice work!
Loved it! Thanks man.
Well done john
Brilliant!
Love this!
Nice. Can't wait to see the knives you make.
That little router plane is so cool!!!!
I don't know if anyone has commented on this but we had heat treating furnaces with porous bricks in the floor and they were a royal pain in the butt. They scale from the parts would react with the brick and chew it up. We had to replace the hearth every other month. Admittedly those furnaces ran 24-7. We eventually restricted those furnaces to bagged parts.
If you ever do need to replace the bricks and element, maybe lay them on a board and slide that into the case and then pull the board back out without the bricks etc. I totally would have dropped those too, glad you didn't.
Good idea :)
Put it in like a pizza in a pizza-oven. Was my first thinking, as John danced with bricks :-)
And we are taking about eating: Now John knows how to drill mashmellows.
Entarra De'Lacord If I understand correctly, is it like the fairly well known Pringles tip?
Nicely done. :) I was half expecting a brick to drop there man. ;) If you ever need to do it again, or someone else does, maybe lay them on a slightly undersize sheet of 1/4" plywood or something to use as a sled to slide them in easier.
Hi John,
The contortions to get the bricks in & out were fun. It was good for a giggle on this end, too.
A thought: why not make the back of the sheet metal removeable, and then you could lower the enclosure down over the brick stack and replace the back? Probably not worth the effort for the number of times you'll be changing the bricks (I'd wager that trenching the new bricks will be a bigger deal).
As always, a fun build so far!
Keep 'em coming.

It's not often you hear someone say that smoke is a good sign in a work shop ;)
Great job. Reminds me of shawshank redemption. :)
Man, you're so pro. Naughty, but pro.
Oh god them squeaking sounds send shivers down my spine like nails down a chalk board how are u coping with it
I had the satisfaction of knowing it will bug the viewers even more than it bugs me :)
I Build It Scrap Bin Next time, make sure to up the dB at those squeeks.
Did anyone notice that?!! Oh my God. I was so worried that the small piece of brick @ 3:02 will fall down and postpone the whole show. Thank you Mr. Johne
With the exception of the controller, this looks fairly affordable! Great job! Does the outside stay cool enough to give it a slick paint job?
Controller is fairly cheap. The bricks were the expensive part.
Excellent video and design John. Could you possibly use some ceramic disks for insulators in the holes for the wire?
I used a piece of perf board
Hello . how long the resistance can last at 1250 ° C
Great Build! Can you tell me where to find the elements for 120 volt?
Congrats! I'm wondering about the case... How hot does it get on the outside? TY!
10:30 to 10:45 I said the same things at my first time LOL
Omg dude you just made my day.
AvengerDK 11:56 to12:06 was more like my first time LOL
this is brilliant, if only i had the guts to mess around with high voltage and fire....
You said you didn't want to use the table saw, even though it seems it would have been much easier. Maybe because of the dust? Or would this material ruin saw blades like even just a small amount of dirt/sand/concrete residue on wood can?
When we had the insulating bricks replaced in our furnace brazing chamber, the guy used a bandsaw to cut all of the bricks.
Cool project! Forgive my ignorance but is this to do the same thing as the propane fired unit you made some time back or is it for the lower temperature process that follows - I think you called it "tempering"?
Maybe just a pice of thin plywood will do as a temporary support while flipping it ower?
I know more is to come.. are you going to have a thermometer to check Temps?
I need to know more about the electrical circuit
Focus master
It looks a good size for a rectangular pizza for one.
I ain't trying to know nothing, but you could have assembled all the bricks on the bench, with the leads tucked in like you did, and then slide the box over the bricks. That is. . . put the bricks that meet the door on the surface of the bench with the hinge side of the core next to the edge of the bench. Once you've slid the box over the core, just rotate the whole shebang onto its bottom. Easier to do than tell.
All the best,

This is a wonderful video as ever. I'm looking to build my own oven, using yours as inspiration. I presume you're using kanthal wire for your element. What guage are you using and what length? Thanks, Matt.
Ok! So I watched the video again and now I remember that you'd lost the label on the kanthal. How many ohms were you aiming for? I'm looking at around 30!?
One of the benefits of having the belly is to hold and maneuver bricks like this. Something skinny people just won't be able to appreciate
How hot will this oven get?
For some reason I was removed from this channel. I did resubscribe
Cool vape bro.
Now you can cook all the TH-cam trolls 🤣
What gauge is the wire?
Great work. IF you ground the case and have what we in sweden Calls a "jordfelsbrytare" you Will be all set as IF the hot and ground touches the fuse Will trip. And also IF you have connection between ground and neutral the "jordfelsbrytare" Will trip. Surely you guys have something similar in canada :))
No, here in Canada we still use knob and tube with pennies stuck in the fuse sockets.
I Build It Scrap Bin actually i expected as much.
I too was going to say something about grounding the case but I know that John knows he should do it, and who knows, maybe he did and just won't say so that he can stir up the safety Susans? It definitely got my inner WHSO excited haha. Irrespectively it probably still needs to be said though, as that is definitely a trap for young players who don't have the same depth of knowledge as the almighty John. Loving the build by the way!
Of course the ground wire is bolted to the case, and you'll see that in the last video. Oh and I finished this oven yesterday morning, so don't get the idea that it was these comments that "clued" me in to grounding the case. I've made from scratch much more complex electrically powered things than this oven.
What mike makes was saying is that it wouldn't be a big deal if the element wire shorted to the case, since it would just trip the breaker. But it would also very likely burn/ melt the element wire where it touched the case, shortening or ending it's lifespan, so obviously it would be better to stop that from happening.
I Build It Scrap Bin yeah right. You should atleast mention where u got the idea about grounding the case from... the swedish safetypolice.
All kidding aside you would probably would fare better from turning down your nasty attitude... noone is impressed with a sixty-something know IT all on youtube.
Except maybe me who is still a fan...
John, where did you get the fire bricks? I built my gas forge out of the 1/2 thick ones years ago, and now I can't find them anywhere, up here.
I got mine from the pottery supply house in Oakville
Thanks John! Now lets see if I can find one of those in Ottawa.
Searching "insulated fire brick Ottawa" on Google should do the trick.
Oh and I had mine shipped. It would have cost me more in gas and time to go get them.
"Insulated" might make a big difference, when I bought them 10(ish) years ago they were labeled "Fire Brick" and that is always what I have searched for...MDDA, (Mon Dieu Dumb Ass) and always just found the heavy, hard ones...
In this one I cut grooves in the firebricks to support the heating element, then installing the element and try it out.

I Build It Scrap Bin can this be used as a forge to
I Build It Scrap Bin You're in your element John without the belly clamp it would have went south. Got one meself works a treat under certain circumstances 👍
Anyone ever tell you your giggle sounds like scooby doo? :D
"Reporting live from South Korea, Stove heating element limbo, a new sport for the olympics, was dominated by Canadian John Heisz."
Great work man....try a egg in it...;-p
The noise of them bricks rubbing I had to turn the sound off
Lol 4 got what kind of wire it is
When you say body, you mean belly!
Make a tray to slide the fire bricks in with, lol.
Could you put that phone number up again please? :)
Looks like I might need to get a t-shirt printed.
867-5309 ? Is that the number you want ? ;)
