I just did a sketch using Adobe Illustrator to show the construction as I would build it. It is much stronger and should hold your oven. If however it isn't and flexes, it is easy to add extra strength in the way of another plywood base. Like a house, the stronger the foundation, the longer it wilL last and the less hassles experienced.

Neil has a good idea,, I also might reccomend using microlams for the sides and leaveng them there, they have a ton of strength and support..

How are you planning (besides the handles) to move it around, ie: back of a pick-up truck ?, Harbor freight has some nice big wheels and ramps that would come in handy...

Keep going as this is a cool idea
Good luck

That is an awesome portable oven. Do you have insulation? I see that there is a white board. Insulation? Is this sufficient? How big is your oven opening?

Thanks for the plans. Nothing like getting visuals to understand. Your plans would make it a lot lighter...Structurally, the steel should be welded together right? I'll have to see if I can find a welder. As far as insulation, is 50mm (2") enough?

I know I can get insulation board from Forno Bravo, but I'd like to get it locally. Anyone know if a big box store or what type of store would carry it?

Refractory insulation boards come from refractory specialists, or pottery suppliers for kiln building. Do a google maps search for refractory dealers near you.

David is obviously more creative then me to cook in a 21" oven. I have a 30" low dome oven that I love, and it cooks a mean pie, but I cannot imagine, nor would I recommend an oven any smaller. I knew before I built it I wanted a larger oven in the future, but it didn't fit my current situation. 3+ months of cooking in my 30" oven has only solidified that more.

What are the maximum and minimum sizes of ovens you owned with..

[david s]

An increase of 20% in diam means an increase of 100% in volume. The bigger your oven the more the weight increases to an alarming level. For a mobile oven to be rolled on and off a trailer it needs to be relatively light and therefore small. If you want a larger moble I would recommend that it be on a permanent trailer. My oven is mounted on a base of areated reinforced concrete (75 mm) and the dome is insulated with 75 mm vermicrete topped with 10 mm ferrocement shell.
