Scotty's 36" Build on the Sunshine Coast, Australia.

[scottsummers]

Long time reader of this forum, I have now started construction on my own 36" oven.
Im using fire bricks (175 of them) on top of a Vermiculite 75mm slab.
I have taken about 10 days to get this far and am about to close the dome, I will do a curing fire about 10 days after closing then apply the Ceramic blanket and mortar/render the final shell.
Photos to follow.

Hi Scott,

You have made a great start it all looks good But!!!!
IMO I would make the flue exit about twice the size it is now.
The width looks OK but it seems to far to narrow not deep enough.
When it comes to the flue entry / exit the bigger the better, it may save some problems later on

Hey Doug, thanks for the heads up, it will be hard to make it any wider (left to right, it's currently 3 bricks wide) but I think I could make it thicker with a bit of ease. I'll cut into the front course of bricks tomorrow to make it 100mm front to back? I have a 2m 150mm stainless flue that will sit ontop, so that should draw well?
I'll make the adjustments tomorrow.
Thanks again.
Scotty

Hey Scott,
That is what I was referring to, the width looks good three bricks will be fine, and if you can cut those bricks and make the exit 100mm that will certainly help, maybe you could even cut them on an angle so that the entry is even deeper at the bottom
