I've finished the dome.
Inserted the fiberglass form which is held in place with a car jack.
Working up the dome
And then poured my keystone with refractory castable.
Once the keystone is set hard I get to remove the form and crawl in the oven on my back to clean and point the joints.
Going to spend the time waiting for the castable to set building up a landing around the door for the granite to sit on.
Still have a lot of work to do, but the hard part is done.
