The space between the two angle irons could be the trough of your flue/vent.

I widened the thickness of the top of the entry by adding another angle iron. I'm feeling so much better now that I did this, and this morning I closed the course above it.

Neil, I still have plenty of space in front for the vent.....about 11" in front at its deepest point and more than 20" across, in an arc shape.
In fact, I'm thinking of using an old lid from my 22" Weber bbq kettle for the vent by cutting it in half and making a cutout for the 6" pipe. I'm hoping this will draw nicely.

Sixth course is now complete and I'm happy with the way things are turning out so far...
I had one sleepless night thinking about the vent transition but once it was right there in front of you things just fell right into place. I worried for nothing...

Did course 7 today...

Nice work. I just got through that vent/dome transition as well and know it is not too easy. Yours looks nice and solid.

Your progress is quite an inspiration. It's making me wish I had cut bricks today.

Looks great George. I like all the sticks holding up the bricks. It's the best way so you can keep working on other stuff. I'm glade you went with a angle iron opening. I haven't seen one currently being built and I think it's a great option.
Will the outer arch be an angle iron too or a brick arch?

Thanks all!

Hi, the outer opening will be rectangular as well, but will also follow the curvature of the hearth. But I'm not sure yet exactly how I'll 'form' this curvature.....most likely a combination of an angle iron and a flat iron/or rebars bent into shape and welded together. This will also serve as support for the vent.
