The oven drop

How to do an oven drop.
everything i'll write about here relates to this starting image.

So what you see here is the dome and front bricks to close off the oven, that thin piece of metal marked by the red arrow is going to be placed from the oven to the front arch to stabilise the structure forward of the oven, from back to front it goes oven then chimney section then front arch, they do not intertwin much so placing a rod across them all it will give strenght.
The metal rods around the dome area marked by the lime green arrow, are there until I do the side walls reinforcing, they presently are not doign anything as the dome is solid by itself but they did help until the mortar had set, i'm just keeping them there to make myself feel better !
The front area marked by the blue arrow is where the front terracotta pavers and cream front arch will be built, the pavers haven't arrived yet and they are not going to be "brick height" so i will need to "build that area up" , i have a few options but haven't decided yet, i think but i will lay a small slab to the correct height.
The area marked by the orange arrow is where the chimney bricks will go, they are located outside of the oven dome ....after the "drop" and before the front arch, the plan is that the drop will force the smoke down and out of the oven and the chimney will suck the smoke up so NO msoke reaches the front cream arch and it remains clean !! big hope? we'll see.
The lightblue/aqua arrow is a bit difficult to see what i mean but it is where the drop starts, but it is actually going to be a third of a brick wide with a full brick infront of it, it will then be an arch 1/3rd of the way into the centre that reaches the full drop bricks. HARD to explain but I intend to fully detail the process with images as i go as it has taken me loads of time to work it out as there is little quality info online i can find.
The thin yellow horizontal line will be a metal "L" bar to rest the bricks on, the squiggly angled yellow lines represent the slanted brick "drop".
Next post I will detail the steps I will take to complete the oven.
