Hi,
on paper, my deviationist design for the hearth support structure looks good, with the concrete blocks laid along the axes of a hexagon.
BUT, I just roughed out the 1850 mm diameter circle and placed 400 x 200 x 200 mm concrete blocks and it feels a bit cramped and over-engineered. So I laid the blocks in a simple cross shape (they don't meet on purpose, so that our abundant little red-bellied black snakes can escape if disturbed). Pls see attached snap.
My question is this: will this provide sufficient support for the round hearth slab and central dome? My hunch is that it's ample, but I'd welcome any input from the knowledgeable people on this excellent forum!
Regards,
Carioca
