Dome wall thickness question

Re: Dome wall thickness question

I decided to go with the 3" wall thickness to maximize floor space. Starting from the 4th course up I can and might go with 4.5" bricks, as there will enough clearance from that course on upward.

I started erecting the dome yesterday:

"As far as the shallow entry goes, it will be rectangular with a flared side wall opening. "

This is what I built and I am glad I did. It is a little trickier to make but you get much improved visibility and accessibility into the oven.

Those were exactly the two reasons for the flared opening.
Also, the fire in the chamber can be seen from a wider area.

no problem i like trying to solve puzzles on cad need any dimention
worked out let me know i have that drawing saved.

Re: Dome wall thickness question

Yes, that makes more sense. It is possible to squeeze your oven opening into the insulation circle, but it makes it more difficult. I did pretty much the same thing, and ended building part of my flue support on the top of my dome.

It's really easier if you give yourself a little more room to work.

Thanks again, olddude.
I realize I don't have much latitude trying to build the largest oven I can fit within a 48" circle, especially placement and design of vent/entry. But I think got it figured out and your cad drawing pretty much nails it.

dmun this is what i was thinking that might work for his requirements

This is what I built and I am glad I did. It is a little trickier to make but you get much improved visibility and accessibility into the oven. Another benefit is that you can design a door with "wings" the same angle as the flare. This makes the door easier to place, makes a better seal and is freestanding without a base or struts.

Re: Dome wall thickness question

I'm afraid I don't understand this drawing. Is the vent in the oven chamber?

That's olddude's drawing. I don't think the square lines drawn inside the chamber are part of the vent.

Re: Dome wall thickness question

if you build and opening like this the vent will work

Re: Dome wall thickness question

might help with the drawing lol

Re: Dome wall thickness question

okay how about this one

[olddude]

Re: Dome wall thickness question

yes 3" is good my bad thought i saw 1"

Re: Dome wall thickness question

i keep trying to send you a readable cad drawing showing 2'8" in side
4 /2" wall 3" of insulation then you could stucco the out side


here is a pick of my first row on end get more room

Re: Dome wall thickness question

from what i've seen on this site and others make the oven smaller stay with the 3" of mas but you need more insulation

thermal mas is where the heat is stored for none fire cooking

so if your insulation is small you will lose heat fast
so even if you had 5" of mass wouldn't mean anything

question how will you be cooking for
