Another kiln update

I've managed to make quite a bit of progress over the last week. The vertical walls are now at the right height for the arch to spring off and the lower passive damper as well as the middle grate fire mouth are also in place. I'v also put a small side stoke port adjacent to the main fire box. This morning I have positioned the front door arch and removed the former. The rear flues are now all in place and the wall above is ready to receive the back end of the arch. All in all it's starting to feel like a kiln. I just have some fiddly spacer bricks to cut with the angle grinder to finish the last course of bricks as the kiln tapers into the flues and then ready to start making the arch formers. I've added images most recent at the top this time. If you're wondering why a lot of the images seem to be in the dark it's due to me recording progress at the end of each day and at 5pm it's pretty pitch.
