I got right back to work on the kiln as soon as I arrived home from Minnesota. I'm just about finished but I have a small punch list to knock out. I still need to cast salt troughs for the firebox and set the bagwalls, set up the burners, and build some storage for the kiln shelves and posts.
I put up a metal roof for the shed and flashed around the chimney.
This is the door frame and the I-beam trolley system. The beam is about 12' long and extends out the side of the shed.
The oil burners require a much smaller and tapered port. I found these plastic funnels that were just the right size. I built a little frame and cast them using Mizzou castable. They should work just fine.
Here is the 99% finished kiln. The door is constructed of high alumina soft brick, this is the same brick I used on both of my previous wood kilns and it held up pretty well. I coated the kiln side of the brick with a thinned down mix of AP Green #36 high alumina cement. I wanted to use greenpatch 421, which is fairly common amongst potters. My supplier was out of that and recommended the #36 as it has a higher amount of alumina, about 70%. I did discover that it will not bond if there is any dust on the brick, which is a tall order for soft brick, but I think I made it work. Time will tell if that coating makes a difference. The door track works great, I can move the 700# door with one hand quite easily. I'm excited about it!
I mixed clay several days ago and it should come out of the racks in a week or so and then it's on to making pots!
