Hi All;    
Started on a new project after stove chat the other day.
Matt Walker suggested, that on my new dragon tech  batchbox doors.
I might want to find a way to Bake the high heat paint on before shipping.
He thought some buyers might have a problem with stinky paint curing in their home during the first burn.

According to the can of 2000F header paint. Freshly painted metal should be brought up to 200F & then cooled for 20 minutes.
Then it is brought up to 400F & then cooled for 20 minutes, finally it is brought up to 600F as a final cure on the paint.

To accomplish this I am designing my new easy bake oven (a no lightbulb version)
Built almost entirely from salvaged pieces on hand.... in the back 40 scrap yard!
I had a large cast iron tub with door from a Victorian estate stove. One side has a 20" hole that the riser will poke thru.
By flipping it upside down and remounting the hinges. I formed the basis for my oven.
A used angle iron frame was perfect size to sit the tub on. Tomorrow I'll extend the legs to bring it up to riser height.
I used my Skamal insulated firebricks to fab a 6" J tube .
The riser is a section of metalbestos insulated chimney.
I'll use a piece of Morgan superwool over the top of the oven to insulate it.

More photo's to follow.

Got the stand made up and got the bottom firebrick bedded in sand!
Now I mix up a batch of mortar and start stacking brick!

A 6" J tube is 5.5" wide...  2x6 planed lumber is 5.5 " perfect as a form board!
Clay sand mortar and sand as a backfill.  The whole core will be covered in a clay cob when I'm done but for now its burning!
I'll get the oven on top as soon as I have help.

And today I got the oven on top of the frame.
I have ceramic blanket over the top and sides and sheet metal over that.
Some nice flat rock to hold the metal down and its time to light it off!

Ignition went very well and before long I had a rocket launch on my hands! Its so cool the way an unrestricted J tube roar's!
Even now hrs later the Skamals still have moisture steaming off.
Without trying very hard I had the easy bake over 440F .

I need to bury the core, in a cob mix. To really seal it up 100%. That should send me up over 500F and headed for the 600F I'm hoping for!

Looks like a hillbilly Star Wars imperial Walker!

A little modest roof over it and you'll be set for baking paint on doors in any condition.

Great job Thomas.

Hi Jordan;   I built this oven to bake the high heat paint on my batchbox doors that I am building for sale.  So not to many bubbly cheese pizzas will be coming from this stove.
I do have my large outdoor wood smoker that I cook in all the time, including bubbly cheese pizzas!

Tried out the easy bake today!
And the first door gets baked !
I never even smelled the paint curing.
Took a bit to get the door up to 600F but it got there

My J tube core will burn hotter, faster after it is buried in cob.
