John's 42inch Aussie WFO

Re: John's 42inch Aussie WFO

I thought I would post some of my Pics of my open fire pitt/Grill that is attached to my WFO.

I cooked a lamb over the festive period and it tasted as good as it looked. The grill is not 100% finished as I need to replace the steel sheeting at the back with a nice piece of Stainless steel!! I also erected a temporary cover over the pit in case it rained and guess what?? It pored!!! Luckily my wifes nagging to erect something temporarily worked out fine. lol

The backing of the wall (behind the steel sheet) is 75mm Insulation bricks that limits any heat transfer to the brick wall and reduces the risk of mortar failure.

Hey John,

Wow! I'm speechless. That keystone is awesome, so precise! Were you an Egyptian pyramid builder in a past life?

Nice BBQ pit. Lamb looks delicious. That's a cool BBQ turning thingamajig.

Thanks for the complement Raffy. I am actually a cabinet maker by trade (now a banker) and i guess the 1mm tolerances in the trade has stayed with me.

The electric motor works great!! I beleive it is good up to 30 Kilos but the average Lamb only weighs about 13 kilos so it works effortlessly. Beats turning it by hand for 3 hours! lol

cheers

Re: John's 42inch Aussie WFO

I started work on the chimney landing today and decided to knock down the existing chimney walls that were single brick and build double brick walls for strength and aesthetic purposes.

I purchased some Solid face bricks that have a splay already cut out of one corner and will use these on the inside edge of both the wall and arch.

I considered cutting this splay out of standard bricks but the cut section would not look very pleasing so I just went with the pre-made bricks.

Hi John, your oven is looking great! I like the contrast of the vent walls and your keystone looks good too. What size vent pipe are you planing on? I'm just asking since it appears wise to have an opening that's roughly double the area of the vent pipe's final area.

BTW: Love your lamb & spit set up. I also just had lamb at my cousins Sunday and they had a 30 pounder spinning on theirs. It's a bit messy chopping it up afterward but that's what you have to do to enjoy it .

Thank you Dino.

I had these bricks as leftover after I built the house so they worked out perfect. I just purchased the additional splayed bricks and as you said are a great contrast against the fire bricks.

To be honest I have no idea about the vent opening or pipe I was going to trawl through various posts/photos for ideas and specifications. I liked the way you designed yours so I might steal some of your ideas (as long as you do not mind). Any recommendations or posts to look at would be much appreciated!!

In relation to the Lamb a 30 pounder sounds like a good Size!! mine was about 26.6 pounds. You are spot on though about getting dirty as it is all part of the experience

Great eye for detail Kombiman. I have had it for over 12 years and it is still like new. As they say only the best will do!!

Thanks Mark. I cannot wait to finish so I can cook in it!! I see you have updated the cosmetic appearance of your oven in you Avatar. The colour scheme looks great!!

Re: John's 42inch Aussie WFO

I have been looking around for a vent pipe and came across the attached flue. I want to buy and use this but I am concerned that the thermal shock will crack the flue. The supplier has cautioned be from using this so close to the fire.

Has anyone had any experience with this type of flue set-up?

If I don't go with this I will end up purchasing a stainless steel 8inch flue.

Re: John's 42inch Aussie WFO

hey John,
Thats a beautiful piece... My only concern is there was a guy from england I think.. A few months ago had something similar and it shattered to pieces from the heat.. Does anyone remember whose build that was ??? maybe you can do a form search for clay chimney pipes

Re: John's 42inch Aussie WFO

That is a chimney cap, not a flue pipe. A lot of money, too. I would be afraid to use it that close to the heat.

Re: John's 42inch Aussie WFO

Hey John,

maybe you can do a fourm search for a chimney cap

I stand corrected.... Now that you have the right information you can get the right answer.. My point was I dont believe the cap is made to use that close to the heat...
Its a shame you cant use something that nice without it being destroyed..

some additional info:
Can chimney pots be installed on outdoor fireplaces?(brick oven ?)
Yes, but you should be aware that clay chimney pots may be susceptible to thermal shock when installed on fireplaces or appliances with a short chimney stack of less than four (4) standard length flue liners due to the close proximity to the heat source.

Re: John's 42inch Aussie WFO

The problem with most pots is that they have unequal thickness's of material; all those decorations. That leads to differential thermal expansion, and thus cracking. They are nice units though.
