Fnbrokens Corner WFO in Canberra, Australia

A weep hole is a good idea but it depends on the amount of potential rain you will get in your area, is the oven being enclosed, is there a roof over the oven, etc. Drilling a weep hole in fairly new concrete is easy with the exception of the steel decking which you will need to come in from the bottom. Also it depend on how you will insulate the floor. If you are placing CaSi directly on the hearth then anything you can do to keep water from getting to the CaSi is important since it very water absorbent (we see quite a few wet CaSi floor issues). Some builders raise the CaSi off the hearth with another type of less water absorbent insulation, ie P or Vcrete layer, FoamGlas, patio blocks, hebel.

Nice progress, I am a fan of a integrated arch pour on the base.

Thanks gents!

I found the arch form work pretty easy to do - took measurements and sketched it out. Cut the boards to size and then did the arch after screwing the panels together. A bit of liquid nails down the edges to keep it all in. Definetley recommend doing it in once piece. Was only an extra 1.5 barrows of concrete, plus the steel to reinforce. Thats said - I'm planning on rendering over the whole lot - so you wont see much at the end of the day.

The oven will be outdoors/uncovered for a period of time - until I can extend the pergola to cover it. I was planning on a 50mm (2inch) V or P crete under the calsil just for that added insurance. I think I will put one in simply because there doesnt seem to be a downside to doing so...

Thanks again!

The arch looks great

Hi all...hoping for a little confirmation/advice.

I need to order my oven materials now...and its a 7 hour drive each way to pick it up - so I want to be really sure that I get everything I need in one go.

I've used the dome calculator (awesome work there deejayoh!) for the number of bricks + a few extra - but it doesnt have all the other components required. With the exception of materials readily available from the local hardware store, does the list below look reasonable/complete?

Material	Unit	Total	Hearth	Dome	Inner Vent	Outer Vent	Flu	General
Oven
LiteFill Perlite (100ltr)	ea	8.0	2.0	6.0				-
CaSil (1000x500x50) - 2 layers	ea	8.0	8.0
Castable heat bank (45MC or 45LC)	ea	4.0	4.0
Firebrick(75x115x230)	ea	280.0	30.0	149.0	18.0	19.0	20.0	44.0
Ceramic Fibre Blanket (7200x610*25)	ea	1.5		1.5
Dektite sealant	ea	1.0						1.0
7" pergola kit	ea	1.0					3.0
Refactory mortar Fireclay (20kg)	ea	4.0						4.0

Many thanks all!

Note: I'm buying a trailer in melbourne at the same time - so saving shipping costs on both the WFO materials and the trailer by going and collecting it all - plus I get a weekend away. Any Canberran's needing supplies - sing out - I can probably pick it up for you (Hallam area only)....

Things seems to have stalled a little bit here... I have now got the WFO and outdoor kitchen to the same stage - Very happy with progress.

Looking good. When is the party?

[fnbroken]

well....after a long winter break I managed to pick up the tools again this weekend...

Tiled the outdoor kitchen so I could at least have a BBQ this summer...

Finding the time for a 16 hour return trip to / from Melbourne is the next challenge!
