As mentioned in Intro I am building a BBQ and WFO. The first bit of the project will be to build BBQ and then WFO. So realistically WFO will mostlikely only start in August or later. But doing my homework and will be buying bits every month etc . But bbq will start in 3 weeks
Foundations etc not a problem but Iam more wondering what is better to use for the actual build of the barrel of the oven to stick the bricks together . Cement fondu powder in a bag or castable? Yes i know homebre is also good but can be hard to sometimes source clay powder or not and then the cost of it . Thank you

Hi there and welcome. i bought my fireclay from jewsons for about 15 pounds or so and only used one bag in the whole build. home brew was easy to make/use and works a treat. can't coment on castable or fondu as i have never used them. someone will be along soon to add though i am sure. the planning faze is a lot of fun enjoy and keep us up to date on your progress. good luck. Dave.

Castable that I have used has very fine grit in it. As you are building a Vault build the castable may not allow you to make a nice tight joint on the inner of the bricks which are closest to the arch former for you vault. If you use ciment fondue...you can only make up small batches at a time as the mortar mixed with this cement goes off quite rapid. I would advise fondue only with a Pompeii build that uses a jig. Myself I would use the homebrew mix.......it's only an opinion......hope you get some more feedback on this.

Thanx terry --Cranny and Sumariadave. WHen you say clay Dave was it solid pliable clay or was it clay powder. if its fire clay like the stuff that comes in a bucket ready mix can you use it to build the structure of the barrel dome with it the stuff in the tub. And if its big joints as inside joints will be small but outside can be bigger can you still use the fireclay ready mix. in my mind i would love to just use ready mix fire clay in a bucket but dont know if its strong enough ? Is it fire clay or fire cement ? www.diy.com/nav/rooms/fires-surrounds/fireside-accessories/fire_cement/-specificproducttype-fire_cement/XL-Fire-Cement-FC2-9271683 or www.pizzaovens4u.com/shop/item.aspx?itemid=15 Homebrew is work but no problem apart from clay powder? dont seam to see clay powder for sale: this is the mix i will use if I get clay powder 3 :1:1:1 sand, clay , lime ,portland .

Thanx CEC> But thats what i am trying to establish is it the clay like the putty pliable in your hand or is it like fire cement that you get in a tub. Or is it clay powder that everybody is talking about . If anybody can please give me a link of this product (Name or brand name ) fireclay or fire powder to make up the homebrew than I can source this . Thanx Gentlemen and Lady's

Thank you CEC> Thats what i thought but just wanted to make sure my terminology is the same as yours and others . (Singing of the same hymn sheet) hahahahah ;D Ye iam very good at sourcing things and is sure i might find some . But if not will avail of your ebay link thank you for that . This forum is briliant with all the info and kind likeminded people . Thanx. Also when the lads say lime re homebrew is it normal builders lime ? I found this brilliant youtube clip and said to myself if i just get to seal all the gaps he has then how much better will it work hahahaaha. I cant seam to find the follow on link that I saw before but he made comments of improving it and getting a door and says it worked a trick . He seams like a very likable person Enjoy : www.youtube.com/watch?v=C1QToDg3Ow0

The clay, like the other guys have said is powdered clay (fire clay) and I bought mine from the local Jewsons using the forum discount. Like I said, nice and cheep and convenient. My mix was 3:1:1:1 fire clay, sand, opc, hydrated lime. I did have to sieve mine though to get it nice and fine and the last lumps I crushed between two bricks to break it up. I also bought from Jewsons some fire cement that came in small pots and looks like putty. It was not what I was looking for at all and is only good for small gaps. My build has many large joins, 5cm or more and is holding up just fine with the home brew.
The fire clay was ordered from Hepworth by Jewsons. They did tell them what it was for and they did not think it was a good idea. What do they know eh? Lol.
Hope that helps.
Dave

maybe I'm fairly lucky as there's a tata steel works down the road and so there's a few refactory places about . Ha, my brother used to work there, and has since moved to one of their Rotherham plants. Umhloti, I did the same as samuraidave and used homebrew. I bought my fireclay (yes it was powered) from the place I bought my firebricks (Liam @ kilnlinings) but I wish I had bought it from Jewsons (£10 cheaper than Liam). My mix was the same: 3 parts powdered fire clay 1 part sand 1 part ordinary portland cemet 1 part hydrated lime (again you can buy this in big bags from Jewsons). All measures done by volume. Good luck with the build, I am extremely looking forward to your pictures, given I am in the process of building my own brick oven and BBQ (albeit at a later date). Duncan

Thanx DuncanM & SamuraiDave. I just learned another thing from the 2 of you re: 3 parts clay. I thought it was 1 part clay and 3 parts sand. But see if you dont ask you wont know. And i am so glad i asked . So that will be my ratio 3 1 1 1 clay , opc, sand , lime Thanx again lads

Whilst it's clearly worked for others I think the official home brew mix is 3 parts sand?
This is from the Forno Bravo Plans Version 2
Portland cement Fireclay Mortar Formula •1 part Portland cement •3 parts sand •1 part lime •1 part fireclay
.....but who's to say that's right? Although they are well respected.
In the New UKWFO Forum it seems a bit 50 / 50 as to which has the 3 Parts.
I'm a newbie though so don't take my word as definitive.

Thanx Pete 123>
In my mind I was also thinking in the lines of the Forno Bravo Plans Version 2
But as you say the other lads arew using the 3parts clay. . I can almost agree with both versions.
My reason for leaning to 3 clay rather than 3 sand is becuase clay is a compound and its also contains (soil which is a form of sand ) BUT i still have to make up my mind . And hopefully get more info on here from the lads re pros and cons. Also which is better re damp weather as we are used to . It will be a toss up ;D

Sorry to "misinform" you in my original post, but I quoted the mix I used wrong. I had "remembered" that mix... however having checked my notes this morning (after reading the confusion in this thread it got me thinking) I actually used:
10 parts sand 6 parts fireclay 2 parts OPC 3 parts hydrated lime.
Hope that doesn't confusion the situation anymore.
Cheers, Duncan
