shed construction 12x20 ft.
CMU foundation going in on gravel bed. approx 6x13ft
This end will have another layer of block for a small rise to the baffle chamber.
figuring out the fire box grate and intakes
floor is in, baffle chamber and chimney floor set.
Interior supporting arch for the back of the ware chamber.
The outside of this little arch is catanary, 22.5x22.5"
The baffle chamber is 22x27". flat top cover of 24" bricks.
A big Thank You to Justin Lambert for discussing the baffle chamber with me. This one is not even half the size of his kiln's, but I'm optimistic it will produce better firings.
Laying out the curved walls.
Vertical walls are 4 bricks high, will need to buttress higher than that.
The "mortar" is liquid fireclay with 70 mesh silica sand. Each brick is dipped before placement.
Placing wedges under the arch former ribs. I was a bit worried that they weren't a steep enough angle. But it worked out.
time to put the lathe on.
Steve the carpenter helping with the lath. Thanks Steve!
final layer of 9" walls, from here up will be single layer hardbrick, kaowool, and skin.
Testing the arch. This is not the final configuration. I studied Simon Levin's kilns to design the front of the arch using castable.
Half brick gaps and others will be filled with castable cement to hold it all together.
I had a lot of small wedges from cutting bricks, and used every one of them on the arch.
The back was a challenging puzzle.
Built a tent around the kiln to keep the castable above 70 degrees, or at least from freezing.
November Super Moon at 4:00 am. Changing propane tanks.
Dropping the form and dismantling it.
First look at the interior.
Temporary door to cure the castable with a small fire and some delicious stout.
Had leftover arch bricks, might as well make some flying buttresses.
New insulating skin coat on all but the sutemma and chimney base.
