So many different approaches to building an WFO. Did the sand form have a binding agent to keep it's shape?

Hey KP - That really is an amazing, no bs account of building an oven. How long did that take? You mentioned SS cable, where does that fit in?

Cheers ........... Steve

The stainless steel cable goes around the oven to counter the lateral force created by the low dome. Without it, the walls would push outward and the oven would collapse.

No, just made it sufficiently damp/wet and that did the trick.

That is correct. Although in truth, because the refractory mortar I used is really strong (by way of trial I tried to smash two pieces of brick that were bonded together with it. Rather than breaking the mortar, it broke the brick), I suspect it would be fine without the steel cable.

But I'd rather be safe than sorry.

Wrapped the oven in some CalSil blanket and chicken wire/mesh.

Next stage: make a form around the dome from some bendy plywood and pouring about 4 inches of perlcrete around the sides and over the top.

Can't have enough insulation...

The weather has been pretty bad over the last three weeks so progress has been slow.

Last weekend I did manage to get some work done in between showers.

I fitted a form made from some flashing steel and poured/shaped perlite concrete around the side and over the top. My vent has been fabricated, so if next weekend the weather is any good, I can fit it and do some curing.

Looks real good and seems quick and easy.

Was the steel arch for brick cutting convenience or aesthetics ?
Are you concerned it will draw lots of heat out of the oven?
Are you concerned it will heat and distort at a different rate to the bricks and cause problems down the track?

It looks from the photos that you have already started curing.
