how do I build the lightest possible oven? - Forno Bravo Forum: The Wood-Fired Oven Community



New Forno Bravo Forum Feature

Forno Bravo Forum Community,

You will notice a new forum at the top of the main page called, "Ask Me Anything". This forum will be used for live one hour "Ask Me Anything" (AMA) sessions hosted by people who are knowledgeable in different areas pertaining to wood fired ovens. How it works:
- Each AMA will have a "sticky" thread where the community can post questions they would like answered during the live session. This will allow everyone to participate even if you can't be online for the live session. These questions will not be answered by the host until the live AMA; if you need an answer quickly, you should post it in the appropriate Forum area for the community to respond.
- Another thread will be posted for the live AMA. Registered users who are logged in during the live session can interact with the host by asking questions and receiving responses.
- The live thread will remain in the AMA forum to view after the session.

To kick off our AMA feature, we have invited author, chef and master bread maker and host of Pizza Quest, Peter Reinhart, to be our first host! Peter will be in the Forum on Monday, February 15th, from 7:00 - 8:00 pm EST. If you are unable to be online during the live session, you can post your questions in the sticky post. Peter will answer those questions during the live session on February 15th. You can view Peter's answers to your questions as well as what happened during the live session in the session thread.

We hope you enjoy this new feature! Please let us know if there is a topic that you'd like to have as an AMA and we'll look for a host!

  • how do I build the lightest possible oven?

    Hi everybody! I have been trying to figure out if I can build some sort of oven that weighs less then 150 LBS. Is there any way that is possible? they all look super heavy. this is the idea that i have. cut a small 1' across by2' deep steel barrel in half, build walls 2 inches thick with very high fire clay, wrap outside with insulation blanket. then make fire brick hearth, It is for a portable project, that will be carried by a multi- person bicycle. any other suggestions?

    Hi MMichaelson,

    Your objectives conflict with each other... Retained heat oven; with out the capacity for storing heat = thermal mass = weight.

    So, with that in mind (that you can't really store heat without mass) you are into more or less uncharted territory; there is less experience here for light weight ovens, than with masonry ovens. If you build a metal structure, with or without insulation, you might build something that would cook with 'fire in the oven' - pizza type cooking, but you won't have the capacity to 'bake' things. You might get some good pointers from this oven build.


    The BrookenCookie built this propane powered oven. He reports great success with pizza events.


    There was another guy in Australia who built a great looking oven with a 35 gallon container cut in half, long ways (my guess is his structure is about the same size as your proposed oven). He built an oven on a real budget, and he reported that he was cooking food (the oven was working just fine!), and I can't find the link for you here. The point is, there are a few bits of experience on this forum that can help you down this path, but we will all benefit if you do build this oven to keep us all informed on how you build it, and how you like the results!

    If you can draft a specific plan you will be able to detail the volume of materials and calculate weight. A good place to start. Based on what you propose, my guess is you will have a great time cooking great food in the oven you propose. You will need to do the math to confirm how much your design will weigh! The Forum recently started a new category just for projects like your's Other Oven Types - Forno Bravo Forum: The Wood-Fired Oven Community .

    Good luck with your build, it sounds like great fun.

      The idea of dragging a WFO around on a bicycle sounds a bit unrealistic. I hope you weren't planning on climbing any hills ?

        I know. If i can get it light enough, I think it will be possible to climb hills, I just need a really good set of gears, and lots of pedal power.

        What I am thinking, especially after looking at that beer keg oven is that I will need to do something with continuing heat- keep a fire going while I cook. thanks for helping me brainstorm, Ill keep you posted.

          Why not fire it up while you're traveling ? The extra breeze should make the fire burn better. The faster you go the hotter she'll get. You could even cook a pizza or six while on the move. You could also ride down a big hill towards a bank and text them a hold up note. Just be sure to jump clear before it hits the front door- safety first always.
