Help for newbie in oz - 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!

  • Help for newbie in oz

    I've been bitten by the bug and am keen to get a WFO in my backyard.

    There seems to be plenty of info around how to build the slab and the oven itself, (thanks to this forum amongst others) but I'm having trouble with respect to getting some good info on building the base.

    If I were to build the base out of cinder blocks for example - do I need to fill every cavity with cement and rebar or just every third or fourth?

    I've little experience in laying bricks/blocks but have seen you can get some spacers to assist in getting all the gaps between each course identical, are there any more tips anyone can share for a novice?

    I've built a small wall with hebel many years ago and found this easy to work with and cut - are hebel products strong enough to build a base out of?

    Any all advice appreciated

    You could use Hebel, but it is expensive. Standard concrete blocks are cheaper and have better availability. If you mortar the first course of blocks and get them positioned and level, then you can use a masonry adhesive like Selleys liquid nails-landscape, for the rest. Filling every second void with concrete and rebar should be sufficient. If you use 6" blocks rather than 8" you will save a lot of time and effort because there's way less to fill.

      You 'dry stack' the blocks - no mortar - then fill. Its a good idea to fill the corners (end blocks) then every second one. Makes it very strong and stable. I actually used polyurethane construction adhesive (PL500) between the blocks, like mortar, but only real thin. Once that sets up, the blocks won't move during the pour.

        Like mingy said Can't get easier.....stack the bock up like leggo and fill every
        2nd core. Strong simple ....cheap

          Dry stack is the way to go, I did fill every other core although some were back to back fills since I used some 1/2 blocks and wanted to ensure they would not float. My dry stack is documented in my Picassa log. Good Luck

            Thanks very much for all the replies and have had a look at your builds (from the links in signatures).

            I think the dry stack is very well suited to my skill level, but is the first course also dry stacked? (that is no cement between the slab and the first row of blocks?)

            It might sound silly trying to save a few inches but I live on a small inner city block and plan to put the oven in the back corner - can I build right up to the edge of the slab or is it absolutely essential that slab be larger that the outside of the base?

              If your slab is level you could dry stack. If it has irregularities you would want to set the block in mortar (first course only) to get it level. In regard to the size - if you are planning on covering the block with brick, you will need the extra 4 inches. If you plan on a simple render on the block you can get away with it.

              Good luck with your build...

                Thanks Les - answers my question on both counts.

                I hope the slab will be spot on level but if not will set the first course with concrete.

                I hadn't thought about giving it a brick veneer but as the back will essentially be on the boundary and not seen, building to the edge of the slab/boundary on that side would be preferable, not only to save on valuable space but prevent rubbish and pests from gathering.

                  "but as the back will essentially be on the boundary and not seen"

                  Be careful, most councils require you to build 1.5m inside any boundary fence. If you end up with a neighbour dispute (smoke issues?) they would be within their rights to demand you demolish it.
                  Mine is right up against the boundary fence and I look after my neighbours with pizza and bread passed over the fence, but this is not necessarily a guarantee.

                    Here is an easy way to make 100% sure your first course is level:

                    Use shims or whatever you have to to make sure the first row of blocks is level. This should be pretty quick and painless.

                    There is this stuff called 'non-shrink grout'. I don't know what they call it where you are. It is sold in 20kg or so bags and is about 8000psi strength (about 2x concrete). You can mix that stuff from the consistency of milk to almost dry. So mix up a batch which is pretty liquid. Pour enough of it into the first row of blocks so it fills in the bottom. You might have to plug the gaps in the bottom, depending on consistency, so it doesn't leak out. Let it set up, which will be a couple hours, and voila your first row will never move again.

                    You can do a lot of very cool things with grout.

                      You can build right on the boundary now just as long as the material is fire rated for 1/2 hour, 1 skin of brickwork is rated at 1/2 hour.

                      Thats from the Building Code of Australia.
