New build - 1.2M dome

[Irish Chippy]

Beautiful build Jon
Did you ever get that Tandoor vessel? Am curious as to the shape you are using.

Jonv, nice build and very informative. Thanks

[jonv]

Thanks very much, and good luck with your build In my view, the key to a good build is in the planning and research - I trawled through lots of builds on here to try to understand all the issues involved before planning my own and I think it was time well spent.

Mate your build is impeccable. I haven’t seen such a precision build as yours, but there probably are some. As such I’m stealing ideas from your post. I just hope mine turns out as good. Cheers from down under !

Hi Marc. There is nowhere for the smoke to go. The gap is filled with ceramic fibre rope and even if it were not, the outer shell completely encloses the oven.

cnegrelli I dug out a photo that shows the break... it's only a small gap so its effectiveness is limited, but it does appear to help a fair bit.

jonv,

Just curious if the break results in smoke escaping prior to going up the flue?

I had some when I was firing it some weeks after the render had been put on. The dome was hotter than usual and if I covered the hole for a moment with a sheet of something I could see vapour gathering on it. The dome is back to being cool to the touch so I guess little steam if any is now escaping but it gives it somewhere to go if (when!?) the insulation does pick up a little moisture

Looking fantastic it's the project that keeps on giving.Do you get any steam from vent?

[jonv]

Nothing much to report Bauldy... finished the gazebo roof, though

Hi boss have you any up to date photos ?

[jonv]

Bit of fun today gently planishing a sheet of copper to make a cover for the dome's steam vent. Drilled some holes in a piece of 22mm pipe and soldered it in the centre of the copper dish. That should keep the rain out

[jonv]

Thanks - I was trying to follow the shape of the underlying firebrick chimney so was left with some odd gaps to fill

[UtahBeehiver]

Nice use of different size bricks and linear and curve lines.

[jonv]

The chimney is finally finished

The brickwork needs a good clean - their rough surface has picked up tons of mortar and I'm not good enough to avoid spreading it all over the place. I have a bit more painting to do and will eventually get around to rendering the base and a few other cosmetic jobs but not in a hurry

[jonv]

The gazebo is almost finished - just a few bits left to fit, then painting, and fibreglassing the roof - so I made a little more progress on the oven's outer skin. I was foolish to think the tricky brickwork was finished with the dome - didn't enjoy this part at all Don't know why, just struggled to get it right. Will be filling in the gap between the sides and arch with some slips before running a couple of full courses around the top.
