Hi from nz

[tanz]

Hey there everyone,from Christchurch, New Zealand,been lurking for a while now,being a sponge to all the great info on here.
Am about to start a venture into the wfo world,so excited.
Wanted to do a brick oven but here in the south of the mighty NZ fire bricks are soooo expensive,hence i have opted for a modular which i have come across.

cheers Tanz

Re: Hi from nz

Gidday, Yeah i'm from Chch also, Sorry didn't see your post before otherwise would have said hi.

There some reasonable supply information here if you haven't read it yet already.

I'm also kinda shafted by the cost of bricks best i can find is about 4.95+gst
i'm thinking of fire bricks for the floor and perhaps arch then the rest out of castable.

How you getting on with your design?

Re: Hi from nz

Sounds like we are going to be doing a very similar oven,we have decided also to go with the firebricks on the floor and arch and a castable that we are getting from Canterbury Clay Bricks.
We have dug out and boxed (we are doing a corner design)and hoping to lay concrete this weekend.
Would be great to keep in touch.

Re: Hi from nz

yeah sounds good, Canterbury clay don't do castable, they sell pretty much everything although i don't know if they have that much in stock though. We are possibly looking at getting half to a full pallet from invercargil direct from the factory later in the year. sounds like your a head of us. I've got structural problems with an existing retaining wall and adjacent tree beside my site which i will need to sort out first, I'm looking at doing a base similar in concept to the Morgans wfo project http://www.fornobravo.com/forum/f21/...uild-6703.html

But just a round dome style oven instead.

Are you going to go geodesic tiles or for full cast. I haven't made up my mind yet.
I'm looking at doing a 900 inside diameter, have you done a drawing up of yours ?

Anyway keep us posted be interested in how you get on and yes would be good to keep in touch.

Re: Hi from nz

G'day guys.
I did a pizza oven here with castable concrete, its much easier than a brick dome, and Im a brickie too....

Re: Hi from nz

Sorry my mistake in saying castable,i meant modular(we have changed our plans so many times it got confusing.Its about a 40 inch oven.

Re: Hi from nz

@Brickie
How thick is your thermal mass? also looks a bit close to the edge on the sides how well did the insulation work there?

@Tanz, Lol, I know what you mean i have so many paper models and drawings laying around i almost don't know whats what anymore... yeah their modular oven looks alright.

What are you planning to do on insulation?
So far we plan on using 100mm Perlite concrete under the firebricks and about 200mm on the outside but still deciding.

Re: Hi from nz

I have no issues with my oven, it takes about 1 1/2 to 2 hours to heat up and retains the heat for hours.
Obviously each oven will be different in the way they perform.

Just build one......

Re: Hi from nz

we are using 50mm silicate board underneath the oven and going to do couple of layers of insulation blanket on top.

Re: Hi from nz

Sweet yeah that will do the deed. did you pick that up from formans insulation?

Re: Hi from nz

Re: Hi from nz

Hey Tanz, where did you get the insulating board from and how much$$$???
cheers rob

[tanz]

Re: Hi from nz

I am getting from Formans here in Christchurch.
There boards are'nt as big as the FB ones but thickness and temp capacity are pretty on par.They measure 610mm length x 300mm width x 50mm thick and will hold temp of up to 1260 degrees c.Price on these boards is $11.70+gst per board (I am getting 8).
Works out a cheaper for me to get 8 of these than one FB BOARD.And I was told I would need 4 of the FB Ones at about $115nz dollars each
They also have the kaowool or supawool.

Re: Hi from nz

Re: Hi from nz
