With much help from my friend, Jon, who cut most of the bricks in to arch bricks,
we got the arch completed and pulled out the former. It was a nice feeling to see this.
The iron work is holding nicely and hence the arch is staying up - I've put 4 inches of ceramic fibre as additional insulation. It looks good.
We gave it a test spin, just because we could, really.
And here is the door in place. I have numbered all these today, and now I have to mix a mortar to paint the brick work with, and to fit the bag wall inside, and I also need to find and clean kiln shelves. Hopefully I'll do a bisque firing next week. I think I have enough pots, although it is a lot bigger than I thought.
Finally, here's a little video of us removing the arch former.
