Locating the arch????

Re: Locating the arch????

If you are going by the plans, than you want to draw it all out to see how your dome will intersect with the arch.

You should read the Teardrop thread, This is what I didn't know. Or check out my build Round shape to see how I am working with my arch being too far out (I was using the plans as my guidelines for the size of the opening).

Im sure its all about dome to arch height that determines where the arch goes?

I think that would be the main determining factor.

By sketching out the dome profile you will more clearly be able to see where the arch top meets the dome and perhaps place the arch there, although this approach may not give you the exact opening width you want to end up with, but close.

Im sure its all about dome to arch height that determines where the arch goes? But I could be wrong.

I did a rough drawing about it for another thread, Ill see if I can find it.

You are right. If the entry is fairly deep you have way more trouble in working the oven. I believe that if you have decent funneling to the flue pipe then you can make the entry not very deep at all. In my case I made the entry only 5" deep, but my oven is only 21" diam with a 5" flue pipe.I also made the oven mouth quite wide to make it easier to work The disadvantage is probably that more heat is lost through the door. I also placed the entry actually inside the oven diameter too. Works ok. every design change is a compromise. It's like boat design.

I'm laying out the floor on my oven - and am marking where I think the arch / opening should be located. I've seen pics of folks that have the arch too far our - and the dome has to "reach" out to the arch.

Is there a rule of thumb for locating the opening / arch? If I'm building a 42" oven with a 20" opening - do I just locate the opening where the 20" intersects the 42" diameter oven wall?

Here's a plan I found where the 20" opening is still set back a bit into the oven:



Here, in Dino's oven - the 20" opening seems to be set outside of the 42" oven diameter:



is there a preferred location? Has anyone seen any pitfalls associated with locating it in a particular place?

Feedback is greatly appreciated.
