New build in Sydney

Re: New build in Sydney

Hey all,

Kinda want to have my chimney like this one, anyone had any experience with making a SS flue like this. Supports, construction, parts etc. Any info would be so helpful. It doesn't appear to have a 'base' plate on top of the rendered finish (I wont be doing a rendered finish, as I cant render for shit). Would like to know is it held in place from below within the chimney arch, or are the supports for the flue at the top and rendered over to cover them up.

Any help would be much appreciated. I will be contacting the relevant professional pizza oven builders during the week, just wanted to get the forums views first.

Cheers
Brendan

Re: New build in Sydney

most are attached by a plate mounted to the vent. one use tapcons, mortar, other. you will need to careful of expanding screws since they will crack the brick that you are mounting to. that flue looks to small in diameter to me for that oven, but can't really tell. Simpson makes a base and several have fabricated their own. flue should be 6-7" internal depending on oven. Your height will determine if it needs support. what is your planned height?

I think all these ovens will belch a little smoke at start up. the trick is a small fire directly in front and under the vent in order to warm the flu and get it drawing. once the draw is good, slide the burning logs/fire back into the oven.

Re: New build in Sydney

For what it is worth I just cut a circle in the bricks with a small angle grinder to accommodate the flue and sealed it with fibreglass rope. I braced the flue pipe to a gutter and when I put a roof over it and an outer chimney and cap it was fitted over the existing flue.

I have been using this for 2 years now and it works fine.

There are some more pics in my build pics.

Re: New build in Sydney

I dont have a roof or gutter to brace to. I need some kind of plate. May just tile/brick over the plate.

How big is your chimney. 8 inch internal?

Re: New build in Sydney

Yes, it is 8" and the chimney through the roof is 10". Are you going to put a roof over yours?

Re: New build in Sydney

I wont have a roof Steve. Its sadly going to out in the open, although push come to shove I could make a covered area, it would be ideal in hotter weather.

Will prob just cut a few floor bricks, stack them on top each other and jam in some fibreglass rope. The chimney will only be 1m high and 8 inch diameter so should be fine.

Cheers all for your help.

Re: New build in Sydney

With the flue being one metre high it should sit ok. The 8" pipe is stable if you have a flat base.

I am happy that I put the roof over mine, just makes it easy to use whatever the weather.

Look forward to seeing your end result.

When your mate says "I want my brick saw bacK"

Well thats motivation to finish the dome. So stuck at it in the rain etc and got the frame done, got most of the dome bricked up but ran out of brickies sand, so off to Bunnings tomorrow and the dome will be complete.

Re: New build in Sydney

Finally finished the dome. What a feeling to have finally finished the hard slog of the dome. Its not as pretty as I hoped for near the top of the dome inside but hey its solid, and wont be going anywhere for a long time and wont make the pizzas taste any less special. Give it a week for drying then I start the curing process. Sydney weather isn't going to help much with the drying times anymore so guess I start playing with my second love in life after pizza, FIRE!

Managed to put a thin layer of home brew fire mortar on as well for shits and giggles. Will then completely dry it out/cure. The Alfoil, ceramic blanket, render etc.

The front chimney arch had to go as it wasnt strong enough and I needed it to go to get inside the oven. Big tip for other builders dont build the chimney arch till you have everything done inside the oven first

Re: New build in Sydney

G'day
Think a bit more before you include the alfloil layer.
Aluminium in open air forms a protective crust of aluminum oxides.
Trap it with mortar. Out of the air with moisture and it will corode big time.
Try this a layer of foil on some damp ground and put a brick on it. Leave it for a week. Lift the brick a week later you pristine foil is turning black. Hold it to the light and you'll probably have holes already. Pick a bit of ground that has lime or cement from the build the results will be worse.

Re: New build in Sydney

Congratulations on completing your dome. Looks good. It is tough learning the hard way and the front arch lesson is valuable to all.

When it comes to the Alfoil layer - like Dave said - think about it again. It is good for lots of things but serves no useful purpose in oven building.

Looking forward to following your progress, it just gets better (and tastier) from where you are at.

Re: New build in Sydney

Ok will leave the alfoil out, I thought I read somewhere it was a goo idea. Thanks.

Re: New build in Sydney

Brendan, I had a flat plate cut out of 6mm stainless with an 8" collar welded on to sit the flue in.
I actually sat in on some wet mortar initially as I had to fire it and cure it for our wedding reception.
I revisited it again afterwards and it was surprisingly solid.
Hi temp silicone now forms a seal and the weight of the 6mm plate is enough for it not to have separated or moved.
