I'm not sure if I missed this in your post somewhere, but I assume you need to use some type of ceramic glass, like a wood stove uses.
BTW, Nice work, as always. Very impressive.

Thanks. I’m going to start with tempered glass like is used in a kitchen oven since I’ve been using a kitchen oven to coat for a while now without issue. Primarily because It’s quite a bit less expensive than the higher temp stuff. I don’t plan on running the oven above ~425 right now. If I want to go hotter at some point I can always upgrade.

Wow, your oven looks like it could be a key piece of equipment for a high tech research lab!!!

Spent the whole weekend on the big I’ve again. Gasket came in for the inspection doors so I broke them down
Drilled out the holes to accept the rivnuts
And began installing the gasket tape.
It’s a silicone foam gasket installed on either side of the glass.
Fairly easy to install and no need to be perfect. The tempered glass gets installed
Gasket to the inside of the trim, and then trim back on the door with the stainless hardware.
And of course the door back on the oven.
The inside
The gasket adds a cool dimension to the inside of the inspection door.
Next I started in on the outer shell and I’ve bracing. I don’t like how sloppy the steel stud walls are so I’m adding six 2.5x2.5x.120 square tube supports that tie the structure of the ceiling to the frame under the oven.

Each will be then tied into the corners of the oven top to bottom with .120 corner guards riveted to the square toning and the studs within the walls.
The tubs are each attached to the bottom frame with brackets primarily to support them while the rest of the work is done but should add strength as well.
Two supports in place, they’re exactly 19.5” apart. Between them will be insulation and some outer wall skins.
The tops bolt through these top plates and into the structure I built into the top of the oven. Now it’s one solid unit.
Lots of rivets. Drilling the panels in place takes a bit but goes faster with a new bit…I found.
With the posts in place now, I cut some skins and began insulating the sides. 2000 degree insulation behind the recessed element boxes and the rockwool behind that.
Panels are inset to match the corners and fastened with rivnuts and 10-24 stainless hardware. Takes longer than rivets but this allows me to gain access easily if I need to get to the ducts or element boxes in the future.
More insulation
More panels
And I ran out of insulation…both sides are to the same point so I’m pleased. Getting very close now to firing it up..

Was tired as **** after the long week so last night I took it easy. Cleaned up and put away all the tools and prep’d for a quick little organization project I’ll tackle this weekend. Need a few shelves below the sand blast cabinet for all the blast accessories, tools, and media. Tired of tripping over it around the cabinet and storing stuff inside the cabinet as well.
This angle was used to attach one of my machines to a shipping pallet and set it aside for this project instead of pitching it.
Since it’s too short, I have to mate two pieces together. Leaving .070 between allows for full pentration sufficient to support weight.
A little flapper disc action gets it flat enough for the project and ready to be cut down to final size. 16 pieces are now 8.

I don't think I've ever tossed a piece of angle more than 1".

They do come in handy. I think I had about 24 of them. I almost threw away half because when would I need 24 pieces of 10” long angle…heh

By now you e figured out that I’m an advocate for tool duplicity to save time and motion. Example - multiple cordless grinders save me needing to swap between cutoff and flap discs. Ain’t cheap but swapping disc for disc 10 times in began session is worth a hundy or two…
Or adding a few extra air grinders so I don’t need to swap deburring cutters during fab. At $50 per, swapping back and forth seems silly…
Or adjusting chamfer depth for various ops isn’t worth $35 per…
90 degree grinders are the same. Sometimes a 3” disc or different grit is the ticket, but swapping drags me down…
Ive set about 2k rivets in the powder coating oven to date. I’ve drilled out maybe a hundred for various reasons and oversized my fair share of holes…two drills has been doable but painful.
Averaging more than 2 changes per rivet prompted me to add two more drills to the fleet.
Remember, time is money even if it’s free time. Efficiency optimizes free time like it does at work. Invest and free yourself up to create.

Insulation and hardware were waiting for me when I got home from work. Stole a couple of hours and got the left side done. Finished up nice but looks as tall as it is now - standing a whoppin 8’ tall.
Here’s a different perspective that better shows how the 1 1/2” of insulation sits between the tubes and the 16ga caps it off.

Still oven…continued on the outer skin and insulation. This time it’s the back of the oven.
Added the vertical post supports drilled and rivnutted into the base frame.
Added the header.
And now it’s back to the insulation and skin game.
Rear is a longer panel so I added a support in the middle, kinda like a standoff. Essentially it attaches to the frame and then creates a way to tie the skin in on the surface of the insulation.
Then it’s rinse and repeat.
Top panel has an access window for the temperature probe.
And a cover with a grommet in it to protect the sensor cable.
Temp sensor installed
And just like that, over shell is DONE

Next step is to get it into its fine position with the machine skates. First moved it forward (into the shop away from the wall) to sweep under it. Damn there was a lot of metal from sheet metal drilling. Moved it maybe 6’ away from the wall/door.
This picture is distorted but gives a better idea of where the overn is within the shop space.
Next step is to get the P gasket installed in the inspection doors. Measure out the spacing and offset of the rivets and drilled the holes for the rivets.
It’s fairly easy with a little patience.
Times two
What’s amazing is that when I designed these in cad I assumed that 3/8 gasket would compress to 1/4” and it does. It’s perfect.
Now to mount the controllers. I cut some and bent hat rails with the correct bit spacing for the boxes and attached them to the right upright supports.
And the boxes installed easily. Like they were designed to.
Im a day away now max.

Are you building an oven or a thermo- nuclear bomb shelter? Either way damn impressive.

And you think they’re not somehow involved?
Nope, max temp is about < 500 degrees or gaskets start to melt…

After about 48 hours you'd have a bunch of charcoal and bones. Then you could run the bones through the shredder into the woods. Or dump them in the septic tank.
Kay.....We're still friends, right?
I'd ask how you know....but then you might have to kill me
With such a badass build and the burn table and router....feels like it needs a name and custom signage. "The Ovenator"...."Powder Melter 5000"...Masterburner.....

Oven name. Oh-**** 3000. It's what I usually say while fishing things out of mine.

Well, I’ve already come up with something. Wanna save it tho so no one else tries to beat me to it. I think it’s really appropriate and sticks with my historical theme a bit.
"gotta see a guy about a thing"
On the first season of Ozark, I built the burner setup JB disposed of a body with. It was an insert that slipped into a real crematory oven. The oven had to cool off for almost 2 days before we could install the panels and it was still very warm. I installed and tested everything the day before filming, which meant crawling in there to connect the gas lines.
Our driver saw me covered with “dust” and freaked out when he found out what they did in that building! He almost didn’t let me ride back to the shop.
