sounds like that thing isnt gonna move,,, good job

[metalmaster]

we set the bottom half of the ball on the pipe. just need to level it up and weld it on

Looks very cool,, how or where you planning your door ??

there have been a couple of design changes over the last couple of weeks.
we were unable to locate a propane tank for the inner dome, so we decided to go with fire bricks alone.
the next step is to pour the perlcrete layer for the floor, the plan is to fill the bottom of the ball with the perlcrete to just below the top and set the bricks flush with the top.
the door will be changed from an arch, to a flat opening for ease of fabrication.
right now it has about 8" of water in it

I get old propane tanks from the propane refilling station,, they let me have the ones that are no longer in service.. ((I make forges out of them)) One time I had to wrestle the scrap metal guy for it....

Have you tried them ???

Cheers

here are a couple of pics showing the pouring of the perlcrete.
it took about 36 cubic feet to fill the bottom of the ball.
we also poured the slab while we were there 55 60 lb bags.
I will be starting a new thread in the Pompeii oven section to post
further work on this project now that we have decided to give up on
the steel dome and switch to bricks.

have you considered casting a dome ?

You won't regret this decision. There's just something about a brick oven. It looks right, it cooks right, and it has the weight of tradition behind it.

the door will be changed from an arch, to a flat opening for ease of fabrication.

Building a brick arch may not be as difficult at you think. Once you start cutting your firebricks you'll see how easy to fabricate they are, as opposed to, say, thick steel plate.

Looking forward to seeing your progress: I think your sphere oven is going to look great.

my dad was a mold maker for precast concrete, so we definitely considered it,
but we ended up going with the bricks

it would be to much trouble to install the top of the sphere using a brick
arch and vent. besides metal is what we do
